Adhesives and adhesive processes (but see below for adhesive processes), including adhesives characterised 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.

This subclass is residual in respect of adhesive processes. Please see the "References out of a residual place" section below, for details of other places for classifying some adhesive processes.

In cases where an adhesive contains an organic non-macromolecular compound as an additive but not as an essential ingredient, 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 is 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:

Macromolecular compounds as such are classified in C08F or C08G. Compositions of macromolecular compounds 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.

Classification guidance:

Allocation of indexing codes:

In this subclass, C-Sets classification is applied to the following groups, listed in the table below, if the document discloses a pertinent combination of technical features that cannot be covered by the allocation of a single symbol. The fourth column of the table indicates the place where the detailed information about the C-Sets construction and the associated syntax rules can be found, in the section Special rules of classification.

The specific C-Sets rule is located at only one place of the base symbol in the section Special rules of classification in the definition. If the C-Sets rule is applicable to all groups of a subclass, it is located at the subclass level only. If the same C-Sets rule is applicable to multiple groups or subgroups within the same subclass, the C-Sets rule is placed at the highest group or subgroup of the multiple groups.

In this subclass, all exemplified compositions should be classified as separate C-Sets. In the absence of examples, at least one C-Set is given on the basis of sufficient disclosure in the document.

Adhesives based on inorganic constituents unless they are based on compositions of mortars, concrete, artificial stone or hydraulic cement.

Coating compositions for adhesives based on non-macromolecular compounds that are able to be polymerized during the film formation step (in-situ polymerization) in the absence of a pre-formed polymer.

Classification guidance:

C-Sets search queries may be made according to C-Sets classification rules described in C09J and related subclasses. In addition, #C8Lz, #C9Dz, and #C9Jz Search Rules may be followed to search for polymers in documents classified prior to April 2012.

Coating compositions for adhesives based on non-macromolecular compounds that are able to be polymerized during the film formation step (in-situ polymerization) in the presence of a pre-formed polymer.

This includes any composition comprising at least one polymerisable ethylenically unsaturated monomer or oligomer that has at least another polymer and is able to be polymerized by means of the known methods leading to macromolecular compounds of C08F 251/00 - C08F 291/185.

C-Sets search queries may be made according to C-Sets classification rules described in C09J and related subclasses. In addition, #C8Lz, #C9Dz, and #C9Jz Search Rules may be followed to search for polymers in documents classified prior to April 2012.

Use of Indexing Codes:

C09J 2203/00 - C09J 2499/008 are indexing codes related to the use of materials in adhesive processes in general or adhesives in the form of films or foils used in conjunction with C09J 5/00 and C09J 7/00 groups.

C09J 2203/00-C09J 2499/008 are used as single symbols and C09J 2400/00 may also be used in C-Sets (in the case of blends or copolymers). C-Sets rules are explained in C09J 2400/00.

Use of indexing codes as single symbols:

Preparing the surfaces to promote bonding such as using a solvent.

The nature of the pre-treated substrate to be bonded, irrelevant to what the pre-treatment might be, e.g. plasma or corona, is indicated by an Indexing Code in the group C09J 2400/00 - C09J 2499/008. For example, a pre-treated polyolefin substrate is classified with the Indexing Code C09J 2423/008.

Adhesive tapes, films or sheets characterised by having an outer adhesive layer to be applied to a substrate. The outer adhesive layer might be covered by a release liner or a release sheet (see illustrative example).

Adhesives in the form of films or foils without carriers.

Adhesives in the form of films or foils on carriers, e.g. plastics, paper, textile fabrics, laminated material.

Carriers with adhesive in the form of films or foils.

Release liners of adhesives in the form of films or foils.

Release coatings on the carrier.

Primer between the carrier and the adhesive.

Illustrative example of subject matter classified in this place:

The illustrative example shows a carrier mounted adhesive film with a barrier layer, a primer coating, a release coating on the carrier layer and a release liner.

Relationship between C09J 7/00 and H01L 21/00:

Subgroups of C09J 7/00 are generally chemistry-oriented subgroups, whereas subgroups of H01L 21/00 are generally process related subgroups.

Relationship between C09J 7/00 and other groups of the subclass: Adhesives in the form of film or foils with or without a carrier layer and being specified by the macromolecular constituent are classified in C09J 101/00 - C09J 201/00.

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.

Relationship between C09J 7/00 areas and B32B areas:

Layered structures in which the adhesive layer is between other layers that are not removable are classified in appropriate B32B areas. When the adhesive layer represents the outermost layer, which may be covered by only a removable release layer, it is classified as an adhesive tape in the appropriate subgroups of C09J 7/00.

See Table 1 below as an example.

Table 1: Difference between a layered structure (B32B) and an adhesive tape (C09J 7/00)

Use of Indexing Codes:

C09J 2203/00 and C09J 2400/00 are indexing schemes that are related to the use of materials in adhesive processes in general or adhesives in the form of films or foils and are used as single symbols or in C-Sets (in the case of blends or copolymers) in conjunction with groups C09J 5/00 and C09J 7/00.

The subgroups of C09J 7/40 cover release liners used to cover the adhesive surface of an adhesive tape as illustrated in the definition statement. Release coating layers being part of the adhesive tape (cf. the illustrative example in the definition statement) 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. illustrative example in the definition statement).

Classification in this subgroup concerns carrier constituted by a metal sheet only.

Classification in this subgroup concerns 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 orthogonal indexing code of C09J 2400/123 – C09J 2499/006. The presence of only resin layers in the laminate is indicated by the orthogonal indexing code C09J 2301/162.

In general, the nature of the resin in the laminate support layer is indicated by the corresponding orthogonal indexing codes 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.

Metallised films or foils are classified in C09J 7/22 or C09J 7/29 depending on the relationship between the metal layer and the adhesive. See Table 2 below.

Table 2: Difference between a metallised film or foil (C09J 7/22) and a laminate carrier layer having one metal layer (C09J 7/29)

Adhesive tape with a laminate carrier that has a textile fabric or paper layer is NOT classified in the subgroups of C09J 7/21.

The presence of a barrier layer, a release coating layer, or a primer layer does not constitute a laminate carrier layer. These layers are considered forming part of the carrier layer (cf. the illustrative example in the definition statement). 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 orthogonal indexing code of C09J 2400/283 and C09J 2400/263, respectively, 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 adhesive composition is applied to the paper or textile fabrics carrier layer. (cf. the illustrative example in the definition statement).

Adhesives that are specified (when the macromolecular constituent is known) and where the emphasis is on the physical nature or the effect produced.

In this place, the physical nature or effect produced refers to non-mechanical, physical nature and/or effects such as optical, electrical or thermal conductivity of the adhesive rather than mechanical properties such as tensile strength, moduli or peel strength.

Adhesives characterised by their mechanical properties are classified according to the specific adhesive or the unspecified adhesive as discussed throughout the C09J definition statement. In other words, the adhesive would be classified as if the mechanical properties were not present.

Classification in C09J 9/00 shall only be done when the adhesive is specified and when the effect due to the presence of an additive cannot appropriately be classified in C08K. The additive responsible for the physical nature or effect produced when the adhesive is specified is classified according to the adhesive and the appropriate C08K symbol for the additive.

Example:

Electrically conductive adhesive comprising a polyurethane adhesive and metallic particles is classified in C09J 9/02 (when the focus of the invention is on the effect obtained), C09J 175/04 (polyurethane) and C08K 3/08 (ADD) (for the additive itself), since C08K 3/08 classifies the metallic particle and not its effect.

Adhesives characterised by their physical nature or effect produced when the adhesive itself is unspecified and the additive is known are classified in C09J 11/00 according to the additive responsible for the physical nature or effect produced.

Example:

Adhesive comprising an unspecified polymer and metallic particles is classified in C09J 11/04 (for the presence of the additive) and in C08K 3/08 (ADD) (for the additive itself).

Additives in adhesive formulations where the adhesive itself is unspecified and the additive is known.

Additives in adhesive formulations where the adhesive itself is specified are classified in the appropriate group in C09J 101/00 – C09J 201/10 and in C08K in the form of a C-Set. See C09J definitions.

Example 2: An adhesive of a blend of 50 parts poly norbornene (C09J 145/00) and 50 parts polyamide (C09J 177/00) is classified as (C09J 145/00, C08L 77/00) and (C09J 177/00, C08L 45/00).

Example 3: An adhesive based on a composition of polynorbornene and containing CaCO3 is classified as (C09J 145/00, C08K 3/26). If this composition contains also a polyamide, then the classification will be (C09J 145/00, C08L 77/00, C08K 3/26).

Example 4: An adhesive based on a composition based on a first polynorbornene (C09J 145/00) and containing a second polynorbornene, a phenol and silica is classified as (C09J 145/00, C08L 45/00, C08K 5/13, C08K 3/36) and in C08L 2205/02.

Example 5: An adhesive based on a composition containing a polyamide in majority, a polyester and a polynorbornene is classified as (C09J 177/00, C08L 67/00, C08L 45/00) and in C08L 2205/03.

Example 6: Adhesives of compositions containing two polymers of the same dot group, for example compositions of two polynorbornenes, are characterised by the orthogonal indexing code C08L 2205/025. The complete classification for such a composition therefore would be (C09J 145/00, C08L 45/00) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Adhesive compositions comprising epoxy resins chemically modified by the reaction of unsaturated compounds

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). The macromolecular compounds are themselves classified in C08G 61/00-C08G 61/127.

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.
