Definition statement

This place covers:

Adhesives and adhesive processes (but see below for adhesive processes), including adhesives characterized by their physical nature or by the effects produced;

Adhesives based on polysaccharides or their derivatives, based on rubbers or their derivatives, based on natural or unspecified macromolecular compounds or their derivatives, or based on organic macromolecular compounds, obtained by (or obtained otherwise than by) reactions only involving carbon-to-carbon unsaturated bonds;

Adhesives based on inorganic substances or on organic non-macromolecular compounds having at least one polymerisable carbon-to-carbon unsaturated bond;

Adhesives in the form of films or foils, including releasable films;

Heat seal adhesives and hot melts;

Use of materials as adhesives, e.g. the use of known or new polymers or products;

Other features of adhesives, e.g. additives for adhesives.

Relationships with other classification places

This subclass is residual in respect of adhesive processes. Attention is drawn to the "References relevant to classification in this subclass (places in relation to which this subclass is residual)" section, below, for details of other places for classifying some adhesive processes.

In cases where an adhesive contains an organic non-macromolecular compound but is not based on that compound, and such a compound is of interest, classification could be made in C08K or as an additive in C08J 3/00 or C09J 11/02. This may be in addition to classification in C09J 123/00-C09J 149/00.

Processes for applying liquids or other fluent materials to surfaces in general are classified in B05D.

Organic dyes or closely-related compounds for producing dyes, mordants or lakes per se, are classified in C09B.

Treatment of inorganic materials other than fibrous fillers used as pigments or fillers are classified in C09C.

Natural resins, French polish, drying-oils, driers, turpentine, per se, are classified in C09F.

Relationship between C08F, C08G, C08L, C09D and C09J

Polymers as such are classified in C08F or C08G. Polymers compositions are classified in C08L. Coating compositions or adhesive compositions are classified in C09D and C09J respectively.

C09D and C09J are seen as "related fields" of C08L - this structure has implications on search and classification.

For classification:

if the claims only pertain to an "adhesive composition...", only the C09J class is given

if the claims pertain to a composition as such and to an adhesive (For example, "composition for use as an adhesive..."), both the C09J class and the corresponding C08L class are given.

For searching both classes are to be searched, regardless of the wording of the claims, since in many documents of C08L, a passage relating to the use of the composition for an adhesive can be found.

Special rules of classification

An adhesive composition with a polymer and organic or inorganic additives should be classified in C09J and C08K for the non-macromolecular component.

Example: An adhesive composition containing polyethylene and amino-propyltrimethoxysilane is classified in groups C09J 123/06 and C08K 5/544.

Use of C-Sets:

When two or more polymers are present in an adhesive composition, classification is given in the form of C-sets: the polymer in majority is given a C09J class (see below), and the minor components are characterised by Indexing Codes. The Indexing Codes are chosen from C08L or C08K and they may be linked or unlinked. The polymer in majority is always first in the C-set.

Therefore at least one Indexing Code must always be present when more than one polymer is mentioned.

Remark: Notes 2 and 4-6 relates to the combination classes which were in use before 2003 or from 09-2003 until 04-2012. In most places, the documents have not been reclassified.

Use of Indexing Codes:

In this group Indexing Codes are used.

  • To indicate the nature of the adhesive an Indexing Code of the type C09J 2400/00-C09J 2499/00 (only head-groups) is given. For example, for an (meth) acrylic adhesive the Indexing Code C09J 2433/00 should be given.

  • To indicate the nature of the pre-treated substrate to be bonded, irrelevant to what the pre-treatment might be, e.g. plasma or corona, an Indexing Code of the type M09J400/00T (T stands for pretreated) is given. For example, for a pre-treated polyolefin substrate the Indexing Code C09J 2423/008 should be given.

To indicate a process of debonding the Indexing Code C09J 2205/302 is given.

Special rules of classification

In this main group, multi-aspect classification is applied, so that subject matter characterised by aspects covered by more than one of its subgroups should be classified in each of those groups.

Adhesives in the form of film or foils without a carrier layer and being specified by the macromolecular constituent are only additionally classified in C09J 7/00 in case that

they show certain properties, e.g. having a textured adhesive surface, having an alternate adhesive layer or being constituted by different adhesive compositions

they relate to an application, e.g. stretch releasable tape.

Properties and applications are indicated by the corresponding Indexing Codes of C09J 2203/00-C09J 2203/342 and C09J 201/00-C09J 2201/626.

Classification of additional information:

In many cases the classification of additional information, e.g. the type of adhesive is very useful for retrieving the document, and therefore very desirable.

For example, if a document discloses an adhesive tape having a carrier and being characterised by an acrylic adhesive layer (covered by C09J 7/385), this document should also be classified in one of the subgroups of C09J 133/00.

Use of Indexing Codes:

In this group Indexing Codes are used.

To indicate the nature of the adhesive an Indexing Code of the type C09J 2401/00 - C09J 2499/00 (only head-groups) is given. For example for an (meth)acrylic adhesive the Indexing Code C09J 2433/00 is given.

To indicate the nature of the barrier layer an Indexing Code of the type C09J 2401/00 - C09J 2499/001 is given . For example for a barrier coating composition comprising a polyvinyl alcohol the Indexing Code C09J 2429/001 should be given.

To indicate the nature of the primer coating composition an Indexing Code of the type C09J 2401/00 - C09J 2499/003 is given. For example for a primer coating comprising an epoxy resin the Indexing Code C09J 2463/003 should be given.

To indicate the nature of the substrate of the adhesive tape an Indexing Code of the type C09J 2401/00- C09J 2499/006 is given. For example for a substrate made of a polyolefin the Indexing Code C09J 2423/006 should be given.

Applications and properties are indicated by the corresponding Indexing Codes of C09J 2203/00-C09J 2203/342 and C09J 201/00-C09J 2201/626. For example the use of an adhesive tape for bundling cables should be indicated by the Indexing Code C09J 2203/302. The presence of an adhesive layer being formed by alternating adhesive areas being chemically different is indicated by the Indexing Code C09J 2201/40 (Fig. 2).

media6.png

In contrast, the presence of different adhesive layers opposing each other is indicated by the Indexing Code C09J 2201/134 (Fig. 3).

media2.png

In case the adhesive layer is interrupted by non-adhesive protrusions extending from the surface of the carrier layer, the Indexing Code C09J 2201/32 is given (Fig. 4).

media3.png

In case the adhesive coating being discontinuous, the Indexing Code C09J 2201/28 is given (Fig. 5).

media4.png

To indicate the presence of an additive in the adhesive or substrate layer the corresponding Indexing Codes C09J 2205/102 and C09J 2205/106 are given. To indicate the nature of the non-macromolecular additive an Indexing Code of the type C08K 3/00-C08K 13/08 is given. For example for an adhesive layer of the adhesive tape comprising an inorganic flame proofing agent the Indexing Code C08K 3/016 may be given as well as the Indexing Code indicating the presence of an additive in the adhesive layer.

Use of C-Sets:

To indicate the nature of a second component in a system a combination of Indexing Codes of the above mentioned type is used.

NB There is no order of the constituents according to their proportions. The codes are given in increasing numerical order.

In order to indicate that the second component relates to a copolymer, the corresponding Indexing Code C09J 2205/114 for should be given. In case of a blend composition the Indexing Code for a copolymer is not given.

For example: For a substrate layer based on a blend of a polyolefin and a polyvinyl acetate the combination of Indexing Codes (C09J 2423/006, C09J 2431/006) should be given.

Additionally, for a substrate layer based on a copolymer of a polyolefin and a polyvinyl acetate the Indexing Code for the copolymer C09J 2205/114 is given.

Further details of subgroups

The subgroups of C09J 7/40 cover release liners used to cover the adhesive surface of an adhesive tape as illustrated in Fig. 1. Release coating layers being part of the adhesive tape (cf. Fig. 1) itself are classified in C09J 7/203, C09J 7/22 and C09J 7/203, C09J 7/21.

This subgroup is given where the release coating composition is applied to the carrier layer (cf. Fig. 1).

This subgroup is given for adhesive tapes having a carrier constituted by a laminate. The presence of a foam, metal, paper, textile or other material layer in the laminate is indicated by the corresponding Indexing Code of C09J 2400/00. The presence of only resin layers in the laminate is indicated by the Indexing Code C09J 2201/162.

In general, the nature of the resin in the laminate support layer is indicated by the corresponding Indexing Code of C09J 2401/00 - C09J 2499/006. For example for a laminate carrier comprising a layer made of a polyolefin the Indexing Code C09J 2423/006 should be given.

Adhesive tape with a laminate carrier having a textile fabrics or paper layer are NOT classified in the subgroups of C09J 7/21.

The presence of a barrier layer, a release coating layer or of a primer layer does not constitute a laminate carrier layer. These layers are considered forming part of the carrier layer (cf. Fig. 1) . In contrast, a carrier layer being coated with an ink receptive layer is considered as a laminate support layer.

Subgroups of C09J 7/21 are given to adhesive tapes having a carrier made of paper or textile fabrics. In order to indicate whether a paper or a textile fabrics carrier layer is present the corresponding Indexing Code of C09J is given.

Laminate carrier layers comprising a layer made of paper of textile fabrics are NOT classified in the subgroups of C09J 7/21, instead laminated carriers are classified in the subgroup of C09J 7/29.

This subgroup is given where the release coating composition is applied to the paper or textile fabrics carrier layer. (cf. Fig. 1).

Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Pressure-sensitive adhesive

Pressure-sensitive adhesive (PSA, self-adhesive, self-stick adhesive) is adhesive which forms a bond when pressure is applied to adhere the adhesive with the adherend. No solvent, water, or heat is needed to activate the adhesive.

Metallised plastic

Metallised plastics are plastics coated with a thin layer of metal, usually aluminium. Metallisation is generally performed using physical vapour deposition, plating or thermal/cold spraying processes. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres.

Special rules of classification
  • Adhesive compositions of cellulose or derivatives thereof in solution, together with other macromolecular compounds, or together with an inorganic or non-macromolecular organic additive are considered as an adhesive composition and are thus classified according to the rules of C09J. They are classified according to the mutual proportions by weight of only the macromolecular constituents, in particular according to the macromolecular constituent present in the highest proportion. If all the constituents are present in equal proportions, the composition is classified according to each of these constituents.
  • Adhesive compositions containing a cellulose and an inorganic or non-macromolecular organic additive as compounding agent are not classified in C08K , but in the C09J subclass together with the corresponding Indexing Code(s) in C08K.

Example 1: Adhesive composition of cellulose acetate in solution is classified in C09J 101/12.

Example 2: An adhesive composition consisting of 60 wt% of microcrystalline cellulose and 40 wt.% of maltodextrin is classified in (C09J 101/04, C08L 3/02).

Example 3: An adhesive composition consisting of carboxymethyl cellulose and glycerol (plasticiser) is classified in C09J 101/286 , C08K 5/053 and C08K 5/0016

  • Last place priority rule: Within each group of this subclass, in the absence of an indication to the contrary, classification is made in the last appropriate place.
  • The subject-matter disclosed in both the claims and the examples of a patent document is to be classified.

They are classified according to the mutual proportions by weight of only the macromolecular constituents, in particular according to the macromolecular constituent present in the highest proportion. If all the constituents are present in equal proportions, the composition is classified according to each of these constituents.
  • Adhesive compositions containing a starch and an inorganic or non-macromolecular organic additive as compounding agent are not classified in C08K, but in the C09J subclass together with the corresponding Indexing Code(s) in C08K.

Example 1: Adhesive composition of starch acetate in solution is classified in C09J 103/06

Example 2: An adhesive composition consisting of 60 wt% of crosslinked starch and 40 wt.% of maltodextrin is classified in (C09J 103/04, C08L 3/02) and C08L 2205/02

Example 3: An adhesive composition consisting of carboxymethyl starch and glycerol (plasticiser) is classified in C09J 103/08, C08K 5/053 and C08K 5/0016

  • Last place priority rule: Within each group of this subclass, in the absence of an indication to the contrary, classification is made in the last appropriate place.
  • The subject-matter disclosed in both the claims and the examples of a patent document is to be classified.

Special rules of classification
  • Adhesive compositions of diene rubbers or their derivatives in minority are given an Indexing Code-code C08L 7/00 - C08L 21/00
  • In the absence of an indication to the contrary, classification is made in the last appropriate place.

  • Adhesive compositions are classified according to the macromolecular constituent or constituents present in the highest proportion: if all these constituents are present in equal proportions the composition is classified according to each of these constituents.

Use of C-Sets:

After the notation of C09J 107/00 - C09J 121/02, classification is given in the form of C-sets: the polymer in majority is given a C09J class, and the minor components are characterised by Indexing Codes. The Indexing Codes are chosen from C08L or C08K and they may be linked or unlinked. The polymer in majority is always first in the C-set.

Therefore at least one Indexing Code must always be present when more than one polymer is mentioned.

Inorganic or non-macromolecular organic materials as compounding agents are classified in C08K; Adhesive compositions classified in C08K according to note 3 of C08K, are not classified in C09J. However, if an adhesive composition contains two polymers and an additive following C08K, classification is made in C09J and an Indexing Code from C08K will be given.

Examples:

a: An adhesive composition comprising a blend of 60 parts polybutadiene (C09J 109/00) and 40 parts polyamide (C09J 177/00) is classified in (C09J 109/00, C08L 77/00).

b: An adhesive composition comprising a blend of 50 parts polybutadiene (C09J 109/00) and 50 parts polyamide (C09J 177/00) is classified in (C09J 109/00, C08L 77/00) and (C09J 177/00, C08L 9/00).

c: An adhesive composition comprising a blend of 60 parts polybutadiene (C09J 109/00), 40 parts natural rubber (C09J 107/00) and 40 parts of silica is classified in (C09J 109/00, C08L 7/00 , C08K 3/36).

Special rules of classification

The main Group C09J 123/00 should not be used.

Majority rule:

For compositions:

If C09J 123/00 relates to a compositions and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09J class (see above), and the minor components are characterised by C-Sets and Indexing Codes. In the case that several polymers can be in majority, several C09J classes for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers:

Copolymers get the class of the major component, except if there is a lower class which specifies the comonomer in minority (see also last place rule), e.g. ethylene butene copolymers (ethylene comonomer in majority) would be classified in C09J 123/0815, and not in C09J 123/20, but ethylene butene copolymers (butene in majority) would be classified in C09J 123/20, not in C09J 123/0815.

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets:

To indicate the nature of the second component in a system, classification is given in the form of C-sets as mentioned above.

Remark: Note 2 after the title is not relevant for C09J 123/00. All documents from before 2003 are reclassified.

Examples:

a. An adhesive of a blend of 60 parts polyethylene (C09J 123/06) and 40 parts polyamide (C09J 177/00) is classified in (C09J 123/06, C08L 77/00).

b. An adhesive of a blend of 50 parts polyethylene (C09J 123/06) and 50 parts polyamide (C09J 177/00) is classified in (C09J 123/06, C08L 77/00) and (C09J 177/00, C08L 23/06).

c. An adhesive based on a composition of polyethylene and containing CaCO3 is classified in C09J 123/06 and C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09J 123/06, C08L 77/00, C08K 3/26).

d. An adhesive based on a composition based on a first polyethylene (C09J 123/06) and containing a second polyethylene, a phenol and silica is classified in (C09J 123/06, C08L 23/06, C08K 5/13, C08K 3/36) and C08L 2205/02.

e. An adhesive based on a composition containing a polyamide in majority, a polyester and a polyethylene is classified in (C09J 177/00, C08L 67/00, C08L 23/06) and C08L 2205/03.

f. Adhesives of compositions containing two polymers of the same subgroup, for example compositions of two ethylene vinylacetate copolymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such a compositions therefore would be (C09J 123/0853, C08L 23/0853) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes:

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications) and C08K (for inorganic or organic non-macromolecular additives) are used.

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe adhesives based on polyethylene, but subject matter of the claim is a adhesive of polyolefin, the document is classified under adhesives of polyethylene (C09J 123/06, C08L--/--).

In C09J, adhesives are classified which have only one polymeric component are also classified, e.g. C09J 123/0815 represents an adhesive of only one ethylene vinylacetate polymer.

Special rules of classification

The main groups of C09J 133/00 should not be used for classification.

Majority rule:

For compositions:

If C09J 133/00 relates to composition of two or more polymers, classification is given as follows: the polymer in majority is given a C09J class (see above), and the minor components are characterised by C-Sets and Indexing Codes. In the case that several polymers can be in majority, several C09J classes for the polymers which are possibly in majority and the Indexing Codes of C08L for all polymers in minority and additives are given.

For Copolymers:

Copolymers get the class of the major monomer component, except if there is a lower class which specifies the comonomer in minority. An adhesive composition based on a copolymer of ethylene and acrylic acid therefore is to be classified in C09J 123/0869 (ethylene in majority), but in C09J 133/02 if acrylic acid is in majority. However, a adhesive based on a copolymer of acrylic ester and acrylonitrile (acrylic ester in majority) would be classified in C09J 133/18. The monomer composition of the main polymer component can be characterised by Indexing Codes of C08F

The classification of the main component polymer of the adhesive should be according to the most specific, or reactive monomer (i.e. glycidyl methacrylate and not methyl methacrylate in a copolymer of glycidyl methacrylate and methyl methacrylate). All comonomers of the main polymeric component should be characterised by their Indexing Codes in C08F (C08F 2220/325 and C08F 220/14.

Use of C-Sets:

To indicate the nature of the second component in a system, classification is given in the form of C-sets as mentioned above.

Remark: Note 2 is relevant for C09J 133/00. Documents from before 2003 are not reclassified.

Common adhesive ingredients like tackifying resins or waxes do only get a C-Sets in C09J 133/00 if they have characterising features for the composition

Examples:

a. An adhesive composition of 60 parts polymethyl methacrylate (C09J 133/12) and 40 parts polyamide (C08L 77/00) is classified in (C09J 133/12, C08L 77/00).

b. An adhesive composition of 50 parts polymethyl methacrylate (C09J 133/12) and 50 parts polyamide (C09J 177/00) is classified in (C09J 133/12, C08L 77/00) and (C09J 177/00, C08L 33/12).

c. An adhesive composition based on polymethyl methacrylate and containing CaCO3 is classified in C09J 133/12 and C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09J 133/12, C08L 77/00, C08K 3/26).

d. An adhesive composition based on a first polymethyl methacrylate (C09J 133/12) and containing as a second polymer a copolymer of acrylic acid, a phenol and silica is classified in (C09J 133/12, C08L 33/02, C08K 5/13, C08K 3/36) and C08L 2205/02.

e. A composition containing a polyamide in majority, a polyester and a polymethyl methacrylate is classified in (C09J 177/00, C08L 67/00, C08L 33/12) and , C08L 2205/03.

f. Adhesive compositions containing two polymers of the same .dot group, for example compositions of two polymers am hydroxyl containing acrylic ester, are characterised by the Indexing Code C08L 2205/025. The complete classification for such a compositions therefore would be (C09J 133/066, C08L 33/066 ) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes:

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F are used.

An adhesive composition containing next to another addition polymer a main component of a copolymer of acrylic ester, acrylamide and hydroxymethylmethacrylate therefore would be classified in C09J 133/26, C08F 220/10 and C08F 220/26, even if less acrylamide monomer is present than acrylic ester and hydroxymethylmethacrylate. If this main component would be in a blend with methylmethacrylate copolymer, an Indexing Code (C09J 133/26, C08L 33/12) would additionally be given.

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used. For example, terpolymers of styrene, vinyl acetate and methyl methacrylate in similar proportions would be classified in C09J 133/12 instead of C09J 125/00 or C09J 131/00. However, Indexing Codes of C08F should be given (C08F 212/08 for styrene, C08F 218/08 for vinyl acetate)

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe adhesives of acrylic copolymers, but subject matter of the claim is a composition of acrylamide copolymer, the document is classified as adhesive of acrylamide copolymers (C09J 133/26, C08L 23/00).

In C09J, adhesives which have only one polymeric component are classified, e.g. C09J 133/08 represents an adhesive of only one acrylic ester polymer.

In the case that several polymers can be in majority, several C09J classes for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Remark: Note 2 is relevant for C09J 135/00. Documents from before 2003 are not reclassified.

Common adhesive ingredients like tackifying resins or waxes do only get a C-Sets in C09J 135/00 if they have characterising features for the composition

Examples:

a. An adhesive of a blend of 60 parts styrene-maleic anhydride copolymer (C09J 135/06) and 40 parts polyamide (C09J 177/00) is classified in (C09J 135/06, C08L 77/00).

b. An adhesive of a blend of 50 parts styrene-maleic anhydride copolymer (C09J 135/06) and 50 parts polyamide (C09J 177/00) is classified in (C09J 135/06, C08L 77/00 ) and (C09J 177/00, C08L 35/06).

c. An adhesive of a composition based on styrene-maleic anhydride copolymer and containing CaCO3 is classified in C09J 135/06 and gets an Indexing Code of C08K, e.g. in C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09J 135/06, C08L 77/00, C08K 3/26).

d. An adhesive of a composition based on a first styrene-maleic anhydride copolymer (C09J 135/06) and containing a second styrene-maleic anhydride copolymer, a phenol and silica is classified in (C09J 135/06, C08L 35/06, C08K 5/13, C08K 3/36) and C08L 2205/025.

e. An adhesive of a composition containing a polyamide in majority, a polyester and a styrene-maleic anhydride copolymer is classified in (C09J 177/00, C08L 67/00, C08L 35/06) and C08L 2205/03.

f. An adhesive of compositions containing two polymers of the same .dot group, for example compositions of two styrene-maleic anhydride copolymer polymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such compositions therefore would be (C09J 135/06, C08L 35/06) and C08L 2205/025. The same applies for adhesive compositions of two polymers only distinguished by physical properties, i.e. molecular weight or density.

Indexing Codes:

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F (for specific monomers) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09J 135/00.

Therefore a terpolymer of styrene, maleic anhydride and acrylic amide should additionally be characterised by an Indexing Code C08F 220/56.

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe adhesives of compositions of styrene-maleic anhydride, but subject matter of the claim is an adhesive of a composition of a vinyl aromatic copolymer, the document is classified as adhesive composition of styrene maleic anhydride copolymer (C09J 135/06, C08L 23/00).

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

a. An adhesive of a blend of 60 parts diene vinylfuran copolymer (C09J 137/00) and 40 parts polyamide (C09J 177/00) is classified in (C09J 137/00, C08L 77/00).

b. An adhesive of a blend of 50 parts diene vinylfuran copolymer (C09J 137/00) and 50 parts polyamide (C09J 177/00) is classified in (C09J 137/00, C08L 77/00) and (C09J 177/00, C08L 37/00).

c. An adhesive of a composition based on diene vinylfuran copolymer and containing CaCO3 is classified in C09J 137/00 and gets an Indexing Code of C08K, e.g. in C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09J 137/00, C08L 77/00, C08K 3/26).

d. An adhesive of a composition based on a first diene vinylfuran copolymer (C09J 137/00) and containing a second diene vinylfuran copolymer, a phenol and silica is classified in (C09J 137/00, C08L 37/00, C08K 5/13, C08K 3/36) and C08L 2205/025.

e. An adhesive of a composition containing a polyamide in majority, a polyester and a diene vinylfuran copolymer is classified in (C09J 177/00, C08L 67/00, C08L 37/00) and C08L 2205/03.

f. An adhesive of compositions containing two polymers of the same .dot group, for example compositions of two diene vinylfuran copolymer polymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such compositions therefore would be (C09J 137/00, C08L 37/00) and C08L 2205/025. The same applies for adhesive compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes:

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F (for specific monomers) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09J 137/00.

Therefore a terpolymer of diene, maleic anhydride and vinyl furan should additionally be characterised by an Indexing Codes C08F 222/00 and C08F 236/06.

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe adhesives of compositions of diene vinylfuran copolymers, but subject matter of the claim is an adhesive of a composition of a diene copolymer, the document is classified as adhesive composition of a vinyl furan copolymer (C09J 137/00, C08L--/--).

In C09J 1/00, also adhesives are classified which have only one polymeric component, e.g. C09J 137/00, an adhesive of only one vinyl furan copolymer

Special rules of classification

Majority rule:

For compositions:

If C09J 139/00 relates to a composition and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09J class (see above), and the minor components are characterised by C-Sets and Indexing Codes. In the case that several polymers can be in majority, several C09J classes for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers:

In C09J 139/00, adhesives do not get the class of the major component of the monomer of the copolymers. An adhesive based on a copolymer of acrylic ester and vinyl pyridine, which has a lower content of vinyl pyridine than acrylic ester, would also be classified in C09J 139/08. Additional classification in C09J 133/08 should be considered. The comonomer in majority should get an Indexing Code in C08F (C08F 220/10 for acrylic esters).

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets:

To indicate the nature of the second component in a system, classification is given in the form of C-sets as mentioned above.

Remark: Note 2 is not relevant for C09J 139/00. All documents from before 2003 are reclassified.

Common adhesive ingredients like tackifying resins or waxes do only get a C-Set notation in C09J 139/00 if they have characterising features for the composition

Examples:

a. An adhesive of a blend of 60 parts vinyl pyridine copolymer (C09J 139/08) and 40 parts polyamide (C09J 177/00) is classified in (C09J 139/00, C08L 77/00).

b. An adhesive of a blend of 50 parts vinyl pyridine copolymer (C09J 139/08) and 50 parts polyamide (C09J 177/00) is classified in C09J 139/08, C08L 77/00) and (C09J 177/00, C08L 39/08).

c. An adhesive based on a composition of vinyl pyridine copolymer and containing CaCO3 is classified in C09J 139/08 and C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09J 139/08, C08L 77/00, C08K 3/26).

d. An adhesive based on a composition based on a first vinyl pyridine copolymer (C09J 139/08) and containing a second vinyl pyridine copolymer, a phenol and silica is classified in (C09J 139/08, C08L 39/08, C08K 5/13, C08K 3/36) and C08L 2205/025.

e. An adhesive based on a composition containing a polyamide in majority, a polyester and a vinyl pyridine copolymer is classified in (C09J 177/00, C08L 67/00, C08L 39/08) and C08L 2205/03.

f. Adhesives of compositions containing two polymers of the same subgroup, for example compositions of two vinyl pyridine copolymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such a compositions therefore would be (C09J 139/08, C08L 39/08) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties (e.g.. molecular weight, density etc.)

Indexing Codes:

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications) and C08K (for inorganic or organic non-macromolecular additives) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09J 139/00

A copolymer of acrylic ester, maleic anhydride and vinyl pyrrolidone used in an adhesive therefore would be classified in C09J 139/06, C08F 220/10 and C08F 222/06.

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe adhesives based on an acrylic polymer containing vinyl pyrrolidone, but subject matter of the claim is an acrylic adhesive, the document is classified under adhesives of vinyl pyrrolidone copolymer (C09J 139/06, C08L--/--).

In C09J, adhesives which have only one polymeric component are classified, e.g. C09J 139/06 represents an adhesive of only one vinyl pyrrolidone copolymer.

Special rules of classification

Majority rule:

For compositions:

If C09J 143/00 relates to a composition and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09J class (see above), and the minor components are characterised by C-Sets and Indexing Codes. In the case that several polymers can be in majority, several C09J classes for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers:

In C09J 143/00, adhesives do not get the class of the major component of the monomer of the copolymers. An adhesive based on a copolymer of acrylic ester and vinyl silane, which has a lower content of vinyl silane than acrylic ester, would also be classified in C09J 143/04. Additional classification in C09J 133/08 should be considered. The comonomer in majority should get an Indexing Code in C08F (C08F 220/10 for acrylic esters).

However, if the major comonomer is ethylene or propene, the corresponding copolymer compositions are classified in C09J 123/0892 or C09J 123/147

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets:

To indicate the nature of the second component in a system, classification is given in the form of C-sets as mentioned above.

Remark: Note 2 is not relevant for C09J 143/00. All documents from before 2003 are reclassified.

Common adhesive ingredients like tackifying resins or waxes do only get a C-Set notation in C09D 143/00 if they have characterising features for the composition

Examples:

a. An adhesive of a blend of 60 parts vinyl silane copolymer (C09J 143/04) and 40 parts polyamide (C09J 177/00) is classified in (C09J 143/04, C08L 77/00).

b. An adhesive of a blend of 50 parts vinyl silane copolymer (C09J 143/04) and 50 parts polyamide (C09J 177/00) is classified in (C09J 143/04, C08L 43/04) and (C09J 177/00, C08L 43/04).

c. An adhesive based on a composition of vinyl silane copolymer and containing CaCO3 is classified in C09J 143/04 and C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09J 143/04, C08L 77/00, C08K 3/26).

d. An adhesive based on a composition based on a first vinyl silane copolymer (C09J 143/04) and containing a second vinyl silane copolymer, a phenol and silica is classified in (C09J 143/04, C08L 43/04, C08K 5/13, C08K 3/36) and C08L 2205/025.

e. An adhesive based on a composition containing a polyamide in majority, a polyester and a vinyl silane copolymer is classified in (C09J 177/00, C08L 67/00, C08L 43/04) and C08L 2205/03.

f. Adhesives of compositions containing two polymers of the same .dot group, for example compositions of two vinyl silane copolymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such a composition therefore would be (C09J 143/04, C08L 43/04) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties (e.g.. molecular weight, density etc.)

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09J 143/00

A copolymer of acrylic ester, maleic anhydride and vinyl silane used in an adhesive therefore would be classified in C09J 143/04, C08F 220/10 and C08F 222/06

Use of C-Sets:

After the notation of C09J 147/00, classification is given in the form of C-sets: the polymer in majority is given a C09J class (see below), and the minor components are characterised by Indexing Codes. The Indexing Codes are chosen from C08L or C08K and they may be linked or unlinked. The polymer in majority is always first in the C-set.

Therefore at least one Indexing Code must always be present when more than one polymer is mentioned.

Inorganic or non-macromolecular organic materials as compounding agents are classified in C08K; Adhesive compositions classified in C08K according to note 3 of C08K, are not classified in C09J. However, if an adhesive composition contains two polymers and an additive following C08K, classification is made in C09J and an Indexing Code from C08K will be given.

Special rules of classification

Majority rule:

For compositions:

If C09J 149/00 relates to a compositions and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09D class (see above), and the minor components are characterised by C-Sets and Indexing Codes. In the case that several polymers can be in majority, several C09D classes for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers:

Copolymers get the class of the major component, except if there is a lower class which specifies the comonomer in minority (see also last place rule), e.g. ethylene copolymers (ethylene comonomer in majority) would be classified in C09D 123/0807, and not in C09D 149/00, but ethylene acetylene (acetylene in majority) would be classified in C09D 149/00, not in C09D 123/08

Last place rule

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets

After the notation of C09J 149/00, classification is given in the form of C-sets: the polymer in majority is given a C09J class (see below), and the minor components are characterised by Indexing Codes. The Indexing Codes are chosen from C08L or C08K and they may be linked or unlinked. The polymer in majority is always first in the C-set.

Therefore at least one Indexing Code must always be present when more than one polymer is mentioned.

Remark: Note 2 is not relevant for C09J 149/00. All documents from before 2003 are reclassified.

Examples:

a. An adhesive composition of a blend of 60 parts polyacetylene (C09J 149/00) and 40 parts polyamide (C09J 177/00) is classified in (C09J 149/00, C08L 77/00).

b. An adhesive composition of a blend of 50 parts poly acetylene (C09J 149/00) and 50 parts polyamide (C09J 177/00) is classified in (C09J 149/00, C08L 77/00) and (C09J 177/00, C08L 49/00).

c. An adhesive composition based on a composition of polyacetylene and containing CaCO3 is classified in C09J 149/00 and C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09J 149/00, C08L 77/00, C08K 3/26).

d. An adhesive composition based on a composition based on a first polyacetylene (C09J 149/00) and containing a second polyacetylene, a phenol and silica is classified in (C09J 149/00, C08L 49/00, C08K 5/13, C08K 3/36) and C08L 2205/02.

e. An adhesive composition on a composition containing a polyamide in majority, a polyester and a polyacetylene is classified in (C09J 177/00, C08L 67/00, C08L 49/00) and C08L 2205/03.

f. An adhesive composition containing two polymers of the same .dot group, for example compositions of two polyacetylenes, are characterised by the Indexing Code C08L 2205/025. The complete classification for such a compositions therefore would be (C09J 149/00, C08L 49/00) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties (e.g.. molecular weight, density etc.)

Special rules of classification

Use of C-Sets:

After the notation of C09J 149/00, classification is given in the form of C-sets: the polymer in majority is given a C09J class (see below), and the minor components are characterised by Indexing Codes. The Indexing Codes are chosen from C08L or C08K and they may be linked or unlinked. The polymer in majority is always first in the C-set.

Therefore at least one Indexing Code must always be present when more than one polymer is mentioned (see Notes 2 and 3 after C09J title).

Examples:

a. An adhesive composition comprising a blend of 60 parts non-specified epoxy resin (C08J163/00) and 40 parts polyamide (C09J 177/00) is classified in (C08J163/00, C08L 77/00).

a': An adhesive composition comprising a blend of 50 parts non-specified epoxy resin (C08J163/00) and 50 parts Novolak epoxy resin (C09J 163/04) is classified in (C08J163/00, C08L 63/04), (C08J163/04, C08L 63/00) and C08L 2205/02.

b. An adhesive composition based of a polyepoxide and containing CaCO3 is classified in C08J163/00, C08K 3/26. If this composition

contains also a polyamide, then the classification will be (C08J163/00, C08L 77/00, C08K 3/26).

Definition statement

This place covers:

Adhesives and adhesive processes (but see below for adhesive processes) based on macromolecular compounds obtained by reactions forming a carbon-carbon bond in the main chain other than polymers obtained by reactions only involving the polyaddition of carbon-to-carbon unsaturated bonds (wherein in the latter case the reactive carbon-carbon group stays intact without cleavage of fragments). Said macromolecular compounds are themselves classified in C08G 61/00-C08G 61/127. The use of such materials as adhesives.

Relationships with other classification places

Relationship with other subclasses of classes C08 and C09:

Macromolecular compounds per se obtained by polyaddition reactions only involving carbon-to-carbon unsaturated bonds wherein the reactive carbon-carbon group stays intact without cleavage of fragments are classified in C08F. Compositions based on monomers of such polymers are also classified in C08F.

This main group includes metathesis polymerization products, but it does not include common addition polymers such as polymethylmethacrylate.

Macromolecular compounds obtained by reactions forming a carbon-carbon bond in the main chain other than polymers obtained by reactions only involving the polyaddition of carbon-to-carbon unsaturated bonds are classified in C08G 61/00. Compositions based on monomers of such polymers are also placed in C08G 61/00.

Coating compositions and other polymer compositions for similar uses, e.g. paints, inks, woodstains and printing pastes, are classified in C09D.

Relationship with other main groups of the same subclass C09J:

Adhesives based on polymers prepared by condensation reactions of aldehydes or ketones with phenols only are classified in groups C09J 161/04 - C09J 161/16, since C09J 161/00-C09J 161/34 take precedence.

For the same reasons, adhesives based on condensation polymers of aldehydes or ketones only are classified in C09J 161/02. Adhesives of polymers, which may otherwise be formed by carbon-carbon bond formation, but which are prepared by condensation reactions other than those involving the formation of carbon-carbon bonds in the main chain are classified in the appropriate groups, e.g. C09J 179/04 for adhesives based on polypyrrole formed from amines and polyketones. Polyketone-based adhesives are classified in C09J 173/00.

Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Addition polymers

An addition polymer is a polymer which is formed by an addition reaction (polyaddition), where monomers bond together via rearrangement of bonds without the loss of any atom or molecule. This is in contrast to a condensation polymer which is formed by a condensation reaction where a molecule, such as water, is lost during the formation.

Condensation polymers

Condensation polymers are macromolecules formed my means of reactions in which water or some other simple molecule is eliminated from 2 or more monomer molecules as they combine to form the polymer (polycondensation).
