Definition statement

This place covers:

Coating compositions, e.g. paints, varnishes, lacquers. This includes paints, varnishes or lacquers characterized by their physical nature or by the effects produced; examples of these are emulsion paints, powdery paints, thixotropic paints, antifouling or underwater paints, luminous paints, electrically-conductive paints, thermosensitive paints, paints providing wrinkle, crackle, orange-peel or multicolour effects, camouflage paints, radiation-absorbing paints, pearl essence, paints for electrophoretic applications or for flame-spraying, etc..

Coating compositions 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. Coating compositions based on all synthetic polymers are included.

Coating compositions based on inorganic substances or on organic non-macromolecular compounds having at least one polymerisable carbon-to-carbon unsaturated bond.

Filling pastes.

Chemical paint or ink removers.

Inks, e.g. printing inks or writing inks.

Correcting fluids, e.g. fluid media for correction of typographic errors by coating.

Woodstains.

Pencil-leads, crayon compositions or chalk compositions.

Pastes or solids for colouring or printing, e.g. pigment pastes.

Use of materials for the above-mentioned compositions, including the use of anti-settling or anti-skinning agents or other additives.

Coating composition is a composition of a protective or decorative covering layer.

Relationships with other classification places

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.

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 a "coating composition...", only the C09D classification is given
  • if the claims pertain to a composition as such and to a coating(For example, "composition for use as a coating..."), both the C09D classification and the corresponding C08L classification are given

For searching: Both C08L and C09D sub-classes should be searched, regardless of the wording of the claims about a coating, since documents classified in C08L may have information relating to the use of the composition for coating. In cases where a coating composition contains an organic non-macromolecular compound of interest but is not based on that compound, such a compound is classified in subclass C08K or as an additive in group C08J 3/00 (e.g. C08J 3/24 for crosslinking agents) or C09D 7/40. This may be in addition to classification in C09D 101/00-C09D 201/00 (see C-Sets below).

Coating composition:

  • In this subclass, coating compositions are classified on the basis of the film-forming compound, physical nature or effects produced.
  • When the film forming compound is a specified organic polymer, classification is given in C09D 101/00 - C09D 201/00.
  • When the film forming compound is a specified inorganic polymer, classification is given in C09D 1/00. When the inorganic coating composition includes an additive, classification is given in C09D 7/40C09D 7/70 and C08K is given as additional symbol.
  • When the coating composition is characterised by the physical nature or the effects produced, classification is given in C09D 5/00 - C09D 5/4496, C09D 7/40 - C09D 7/70 and C08K (additional symbol).
  • Coating compositions containing specific organic macromolecular substances are classified according to the macromolecular substance.
  • Coating compositions comprising specific macromolecular substances with other macromolecular substances and/or non-macromolecular substances are also classified under the form of C-Sets as explained below.
  • Coating compositions containing a single polymer and an inorganic or non-macromolecular organic additive as compounding agent are not classified in C08K, but in the C09D subclass together with the corresponding symbol in C08K in the form of C-Sets as explained below (i.e. #C9De).

Allocation of indexing codes:

  • Orthogonal Indexing Codes C08L 2201/00 - C08L 2555/86 are used to specify the role, applications and the characteristics of the polymer compositions.
  • Orthogonal Indexing codes may be allocated in conjunction with combination-set symbols. In these situations, allocations of specific indexing codes are indicated with the related C-Sets in C-Sets classification. 

Combination sets (C-Sets):

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 definition section "Special rules of classification".

Further subdivisions:

When the priming paint relates to an anti-corrosive paint on a metallic substrate.

C09D 5/08 or C09D 5/10 take precedence over this group.

These coatings can be easily removed by washing, e.g. with an alkaline composition. When a coating needs to be removed with a stripping composition according to C09D 9/00 classification in C09D 5/008 is not appropriate.

When the temporary coating can be removed as a coherent film.

C09D 5/20 takes precedence over this group.

Powder slurries are classified in this group and not in C09D 5/03.

Relates to in-can preservation of the (aqueous) emulsion paint.

C09D 5/032 takes precedence over this group.

Thixotropic paints are used on vertical surfaces, where sagging should be avoided. A thixotropic fluid displays a decrease in viscosity over time at a constant shear rate. The thixotropic effect can be obtained by certain clays that also have an anti-settling effect (C09D 7/45).

In contrast a shear thinning or structurally viscous fluids display a decreasing viscosity with increasing shear rate.

The paints provide an anti-microbial effect of the coated film. When the paint prevents the occurrence of contamination visually noticeable on its surface C09D 5/16 takes precedence over this group.

The surface fouling is a visual fouling.

Paints containing hydrolysable groups.

C09D 5/1643 takes precedence over this group.

Paints characterised by the film-forming substance.

C09D 5/1637 takes precedence over this group.

Coatings having a metallic effect without colour interference.

The groups C09D 5/4403 - C09D 5/4476 relating to paints based on a specified

film-forming polymer or mixture of polymers take precedence over the groups

C09D 5/448 - C09D 5/4496 relating to paints characterised by other features.

Special rules of classification

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.

Classification guidance:

  • The subject-matter disclosed in both the claims and the examples of a patent document is to be classified.
  • Coating compositions containing a single polymer and an inorganic or non-macromolecular organic additive as compounding agent are not classified in C08K, but in the C09D subclass together with the corresponding symbol in C08K in the form of C-Sets as explained below (i.e. #C9De).
  • Coating 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 a coating composition and are thus classified according to the rules of C09D.

C-Sets classification:

C-Sets statement: #C9Dc, #C9De, and #C9Df

  • In groups C09D 101/00 - C09D 201/10 coating composition based on polymers, and when present non-macromolecular additive(s), are classified in the form of C-Sets according to the relative proportions by weight percentage of the macromolecular constituents.
  • In #C9Dc, the base symbol, representing the polymer in majority, is taken from the groups C09D 101/00 - C09D 201/10, whereas the subsequent symbol(s) representing the polymer in minority is (are) taken from the groups C08L 1/00 - C08L 101/16.
  • In #C9De, the base symbol, representing the polymer, is taken from the groups C09D 101/00 - C09D 201/10, whereas the subsequent symbol(s) representing compound(s) used as an additive(s), is (are) taken from the groups C08K 3/00 - C08K 13/08.
  • In #C9Df, the base symbol, representing the polymer in majority, is taken from the groups C09D 101/00 - C09D 201/10, whereas the subsequent symbol(s) representing the polymer(s) in minority is (are) taken from the groups C08L 1/00 - C08L 101/16 and further subsequent symbols representing compound(s) used as an additive(s), is (are) taken from the groups C08K 3/00 - C08K 13/08.
  • In addition to C-Set #C9Dc, #C9De or #C9Df, a single symbol is given 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.
  • In the case that several polymers can be in majority, separate C-Sets should be made based on each polymer in majority and its component(s) in minority.
  • Attention is drawn to coating compositions comprising, next to a major macromolecular compound according C09D 101/00 - C09D 201/00 (excluding C09D 183/02 - C09D 183/16), two or more Si-based polymers in accordance with C08G 77/00 which are classified according to #C9Dc(Si) or #C9Df(Si) as explained below.

Special rules of classification

Last place priority rule:

Within each subgroup of this group, in the absence of an indication to the contrary, classification is made in the last appropriate place.

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 coatings based on polyethylene, but subject-matter of the claim is a coating of polyolefin, the document is classified under coatings of polyethylene, e.g. (C09D 123/06).
  • In C09D 123/00, coatings that have only one polymeric component are also classified, e.g. C09D 123/0815 is used for a coating of only one ethylene vinylacetate polymer.
  • Single polymers and their preparation are to be classified in C08F 210/00 on the basis of sufficient disclosure in the document.

Choice of symbol for copolymer:

  • a composition of copolymers get the symbol of the major component, except if there is a lower group which specifies the comonomer in minority (see also last place rule), e.g. ethylene butene copolymers (ethylene comonomer in majority) would be classified in C09D 123/0815, and not in C09D 123/20, but ethylene butene copolymers (butene in majority) would be classified in C09D 123/20, not in C09D 123/0815.
  • In addition, a separate C-Set representing the copolymer that is formed according to the monomers of C08F must also be given.

C-Sets classification:

In this group, C-Sets (#C9Dc, #C9De, #C9Df, #C9Dc(Si) and #C9Df(Si)) are used. The detailed information about the C-Sets construction and the associated syntax rules are found in the "Special rules of classification" in C09D 101/00.

  • If C09D 123/00 relates to a compositions and two or more polymers are present, classification is given in the form of C-Sets according to the relative weight percentage of the polymer constituents.
  • The polymer in majority is given a symbol as a base symbol, and the polymers in minority are given symbols as subsequent symbols in the form of C-Sets.
  • If all the constituents are present in equal weight percentage, the composition is classified according to each of these constituents.
  • In the case that several polymers can be in majority, separate C-Sets should be made based on each polymer in majority and its component(s) in minority.
  • Orthogonal indexing codes C08L 2201/00 - C08L 2555/86 are also given if applicable.

Example 1: A coating of a blend of 60 parts polyethylene (C09D 123/06) and 40 parts polyamide (C08L 77/00) is classified as (C09D 123/06, C08L 77/00).

Example 2: A coating composition containing 80 parts of polyethene and 20 parts of polyvinylchloride is classified as (C09D 123/06, C08L 27/06).

Example 3: A coating of a blend of 50 parts polyethylene (C09D 123/06) and 50 parts polyamide (C09D 177/00) is classified as (C09D 123/06, C08L 77/00) and (C09D 177/00, C08L 23/06).

Example 4: A coating composition containing 50 parts of polyethene and 50 parts of polyvinylchloride is classified in (C09D 123/06, C08L 27/06) and in groups (C09D 127/06, C08L 23/06).

Example 5: A coating based on a composition of polyethylene and containing CaCO3 is classified in (C09D 123/06, C08K 3/26). If this composition contains also a polyamide, then the classification will be (C09D 123/06C08L 77/00, C08K 3/26).

Example 6: A coating based on a composition based on a first polyethylene (C09D 123/06) and containing a second polyethylene, a phenol and silica is classified as (C09D 123/06, C08L 23/06, C08K 5/13, C08K 3/36) and C08L 2205/025.

Example 7: A coating based on a composition containing a polyamide in majority, a polyester and a polyethylene is classified as (C09D 177/00C08L 67/00, C08L 23/06) and C08L 2205/03.

Example 8: Coatings of compositions containing two polymers of the same dot group, for example compositions of two ethylene vinylacetate copolymers, are characterised by the orthogonal indexing code C08L 2205/025. The complete classification for such a composition therefore would be (C09D 123/0853C08L 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.

Special rules of classification

Classification guidance:

  • Classification should be made based on the examples, but not the general claims in the documents. The use of main group symbols should be avoided if there are subgroups which cover the subject matter to be classified. The classification should be made in the most indented subgroup that covers the subject matter.
  • For example, a document claiming coating compositions of a polymer of an unsaturated alcohol monomer, wherein the examples are limited to e.g. polyvinyl alcohol, should be classified in C09D 129/04 and not in C09D 129/02 or C09D 129/00.

C-Sets classification:

In this group, C-Sets (#C9Dc, #C9De, #C9Df, #C9Dc(Si) and #C9Df(Si)) are used for classification. The detailed information about the C-Sets construction and the associated syntax rules are found in the Special rules of classification in C09D 101/00.

C-Sets searches:

C-Sets search queries may be made according to C-Sets classification rules described in C09D 101/00 and related subclasses. In addition, #C8Lz, #C9Dz and #C9Jz Search Rules may be followed to search for polymers with additives in documents classified prior to April 2012.

Special rules of classification

Last place priority rule:

  • Within each subgroup of this group, in the absence of an indication to the contrary, classification is made in the last appropriate place.
  • For example coating compositions comprising terpolymers of styrene, vinyl acetate and methyl methacrylate in similar proportions should be classified in C09D 133/12 instead of C09D 125/00 or C09D 131/00.

Classification guidance:

  • The monomer composition of the main polymer component can be characterised by a C-Set in C08F on the basis of sufficient disclosure in the description or claims.
  • Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe compositions of acrylic copolymers, but subject matter of the claim is a composition of acrylamide copolymer, the document is classified as composition of acrylamide copolymers C09D 133/26.
  • The classification of the main component polymer of the composition should be according to the most specific, or reactive monomer, e.g. 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 symbols in C08F, e.g. C08F 220/32 and C08F 220/14.

Choice of symbol for Copolymers:

  • In a coating composition comprising a copolymer, the copolymer is given the symbol on the basis of the major component, except if there is a lower group which specifies the comonomer in minority.
  • A coating composition based on a copolymer of ethylene and acrylic acid therefore is to be classified in C09D 123/0869 (ethylene in majority), but in C09D 133/02 if acrylic acid is in majority. However, a coating based on a copolymer of acrylic ester and acrylonitrile (acrylic ester in majority) would be classified in C09D 133/20.
  • However, a coating based on a copolymer of acrylic ester and acrylonitrile (acrylic ester in majority) would be classified in C09D 133/20.
  • In addition, a separate C-Set representing the copolymer that is formed according to the monomers of C08F must also be given.
  • The classification of the main component polymer of the coating composition 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).
  • Thus coating compositions comprising copolymers wherein anhydride, carboxylic acid or metal salt containing monomers are present are classified in C09D 133/064; wherein hydroxyl-containing monomers are present are classified in C09D 133/064, copolymers wherein glycidyl-containing monomers are present are classified in C09D 133/068.

C-sets classification:

In this group, C-Sets (#C9Dc, #C9De, #C9Df, #C9Dc(Si) and #C9Df(Si)) are used for classification. The detailed information about the C-Sets construction and the associated syntax rules are found in the Special rules of classification in C09D 101/00.

  • If C09D 133/00 relates to a composition and two or more polymers are present, classification is given in the form of C-Sets according to the relative weight percentage of the polymer constituents.
  • The polymer in majority is given a symbol as a base symbol, and the polymers in minority are given symbols as subsequent symbols in the form of C-Sets.
  • A single symbol is given according to the macromolecular constituent present in the highest proportion.
  • If all the constituents are present in equal weight percentage, the composition is classified according to each of these constituents.
  • In the case that several polymers can be in majority, separate C-Sets should be made based on each polymer in majority and its component(s) in minority.
  • Orthogonal indexing codes C08L 2201/00 - C08L 2555/86 are also given if applicable.

Example 1: A coating composition of 60 parts polymethyl methacrylate (C09D 133/12) and 40 parts polyamide (C08L 77/00) is classified as (C09D 133/12, C08L 77/00).

Example 2: A coating composition of 50 parts polymethyl methacrylate (C09D 133/12) and 50 parts polyamide (C09D 177/00) is classified as (C09D 133/12, C08L 77/00) and (C09D 177/00, C08L 33/12).

Example 3: A coating composition based on polymethyl methacrylate and containing CaCO3 is classified as (C09D 133/12, C08K 3/26). If this composition contains also a polyamide, then the classification will be (C09D 133/12, C08L 77/00, C08K 3/26).

Example 4: A coating composition based on a first polymethyl methacrylate (C09D 133/12) and containing as a second polymer a copolymer of acrylic acid, a phenol and silica is classified as (C09D 133/12, C08L 33/02, C08K 5/13, C08K 3/36) and C08L 2205/02.

Example 5: A composition containing a polyamide in majority, a polyester and a polymethyl methacrylate is classified as (C09D 177/00, C08L 67/00, C08L 33/12) and C08L 2205/03.

Example 6: Coating compositions containing two polymers of the same dot group, for example compositions of two polymers amhydroxyl containing acrylic ester, are characterised by the orthogonal indexing code C08L 2205/025. The complete classification for such a composition therefore would be (C09D 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.

Special rules of classification

Further subdivision:

Polymers containing an acrylamide or acrylimide containing a nitrogen containing substituent would be classified in C09D 133/24.

For Copolymers:

  • C09D 139/00 may also be given when the monomer described therein is in minority in the copolymer of a coating composition. A coating 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 C09D 139/08. Additional classification in C09D 133/08 should be considered.

Last place priority rule:

Within each subgroup of this group, in the absence of an indication to the contrary, classification is made in the last appropriate place.

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 coatings of compositions of acrylic ester vinyl pyrrolidone copolymers, but subject matter of the claim is a coating of a composition of an acrylic ester copolymer, the document is classified as coating composition of vinyl pyrrolidone copolymer (C09D 139/06)

C-Sets classification:

In this group, C-Sets (#C9Dc, #C9De, #C9Df, #C9Dc(Si) and #C9Df(Si)) are used for classification. The detailed information about the C-Sets construction and the associated syntax rules are found in the Special rules of classification in C09D 101/00.

  • If C09D 139/00 relates to a composition and two or more polymers are present, classification is given in the form of C-Sets according to the relative weight percentage of the polymer constituents.
  • The polymer in majority is given a symbol as a base symbol, and the polymers in minority are given symbols as subsequent symbols in the form of C-Sets.
  • A single symbol is given according to the macromolecular constituent present in the highest proportion.
  • If all the constituents are present in equal weight percentage, the composition is classified according to each of these constituents.
  • In the case that several polymers can be in majority, separate C-Sets should be made based on each polymer in majority and its component(s) in minority.
  • Orthogonal indexing codes C08L 2201/00 - C08L 2555/86 are also given if applicable.

Example 1: A coating of a blend of 60 parts vinyl pyrrolidone copolymer (C09D 139/06) and 40 parts polyamide (C08L 77/00) is classified as (C09D 139/06, C08L 77/00).

Example 2: A coating of a blend of 50 parts vinyl pyrrolidone copolymer (C09D 139/06) and 50 parts polyamide (C09D 177/00) is classified as (C09D 139/06, C08L 77/00) and (C09D 177/00, C08L 39/06).

Example 3: A coating of a composition based on vinyl pyrrolidone copolymer and containing CaCO3 is classified as (C09D 139/06, C08K 3/26). If this composition contains also a polyamide, then the classification will be (C09D 139/06, C08L 77/00, C08K 3/26).

Example 4: A coating of a composition based on a first vinyl pyrrolidone copolymer (C09D 139/06) and containing a second vinyl pyrrolidone copolymer, a phenol and silica is classified in (C09D 139/06, C08L 39/06, C08K 5/13, C08K 3/36) and C08L 2205/025.

Example 5: A coating of a composition containing a polyamide in majority, a polyester and a vinyl pyrrolidone copolymer is classified as (C08L 77/00, C08L 67/00, C08L 39/06) and C08L 2205/03.

Example 6: A coating of compositions containing two polymers of the same dot group, for example compositions of two vinyl pyrrolidone copolymers, are characterised by the orthogonal indexing code C08L 2205/025. The complete classification for such compositions therefore would be (C09D 139/06, C08L 39/06) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Special rules of classification

Last place priority rule:

Within each subgroup of this group, in the absence of an indication to the contrary, classification is made in the last appropriate place.

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 coatings of compositions of acrylic ester vinyl thioethanol, but subject matter of the claim is a coating of a composition of an acrylic copolymer, the document is classified as coating composition of a vinyl thioethanol copolymer C09D 141/00.

For Copolymers:

  • C09D 141/00 may also be given when the monomer described therein is in minority in the copolymer of a coating composition. A coating based on a copolymer of acrylic ester and vinyl thioethanol which has only a low content of vinyl thioethanol, would be classified in C09D 141/00. Additional classification in C09D 133/08 should be considered.
  • In addition, a separate C-Set representing the copolymer that is formed according to the monomers of C08F must also be given.

C-Sets classification:

In this group, C-Sets (#C9Dc, #C9De, #C9Df, #C9Dc(Si) and #C9Df(Si)) are used for classification. The detailed information about the C-Sets construction and the associated syntax rules are found in the Special rules of classification in C09D 101/00.

  • If C09D 141/00 relates to a composition and two or more polymers are present, classification is given in the form of C-Sets according to the relative weight percentage of the polymer constituents.
  • The polymer in majority is given a symbol as a base symbol, and the polymers in minority are given symbols as subsequent symbols in the form of C-Sets.
  • A single symbol is given according to the macromolecular constituent present in the highest proportion.
  • If all the constituents are present in equal weight percentage, the composition is classified according to each of these constituents.
  • In the case that several polymers can be in majority, separate C-Sets should be made based on each polymer in majority and its component(s) in minority.
  • Orthogonal indexing codes C08L 2201/00 - C08L 2555/86 are also given if applicable.

Example 1: A coating of a blend of 60 parts acrylic ester vinyl thioethanol copolymer (C09D 141/00) and 40 parts polyamide (C08L 77/00) is classified as (C09D 141/00, C08L 77/00).

Example 2: A coating of a blend of 50 parts acrylic ester vinyl thioethanol copolymer (C09D 141/00) and 50 parts polyamide (C09D 177/00) is classified as (C09D 141/00, C08L 77/00) and (C09D 177/00, C08L 41/00).

Example 3: A coating of a composition based on acrylic ester vinyl thioethanol copolymer and containing CaCO3 is classified as (C09D 141/00, C08K 3/26). If this composition contains also a polyamide, then the classification will be (C09D 141/00, C08L 77/00, C08K 3/26).

Example 4: A coating of a composition based on a first acrylic ester vinyl thioethanol copolymer (C09D 141/00) and containing a second acrylic ester vinyl thioethanol copolymer, a phenol and silica is classified in (C09D 141/00, C08L 41/00, C08K 5/13, C08K 3/36) and C08L 2205/025.

Example 5: A coating of a composition containing a polyamide in majority, a polyester and an acrylic ester vinyl thioethanol copolymer is classified as (C08L 77/00, C08L 67/00, C08L 41/00) and C08L 2205/03.

Example 6: A coating of compositions containing two polymers of the same dot group, for example compositions of an acrylic ester vinyl thioethanol copolymer polymers with two different polyethylenes, are characterised by the orthogonal indexing Code C08L 2205/025. The complete classification for such compositions therefore would be (C09D 141/00, C08L 23/06), C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Special rules of classification

Last place priority rule:

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 coatings based on polynorbornene, but subject matter of the claim is a coating of polyolefin, the document is classified under coatings of polynorbornene C09D 145/00.
  • Specific other monomers can be characterised in C08F.

For Copolymers:

  • Copolymers get the symbol of the major component, except if there is a lower group 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 145/00, but ethylene norbornene (norbornene in majority) would be classified in C09D 145/00, not in C09D 123/08.
  • In addition, a separate C-Set representing the copolymer that is formed according to the monomers of C08F must also be given.

  • If C09D 145/00 relates to a composition and two or more polymers are present, classification is given in the form of C-Sets according to the relative weight percentage of the polymer constituents.
  • The polymer in majority is given a symbol as a base symbol, and the polymers in minority are given symbols as subsequent symbols in the form of C-Sets.
  • A single symbol is given according to the macromolecular constituent present in the highest proportion.
  • If all the constituents are present in equal weight percentage, the composition is classified according to each of these constituents.
  • In the case that several polymers can be in majority, separate C-Sets should be made based on each polymer in majority and its component(s) in minority.
  • Orthogonal indexing codes C08L 2201/00 - C08L 2555/86 are also given if applicable.

Special rules of classification

Last place priority rule:

Within each subgroup of this group, in the absence of an indication to the contrary, classification is made in the last appropriate place.

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 coatings based on polyacetylene, but subject matter of the claim is a coating of polyolefin, the document is classified under coatings of polyacetylene (C09D 149/00).

For Copolymers:

In a coating composition comprising a copolymer, the copolymer is given the symbol on the basis of the major component, except if there is a lower group 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.

C-Sets classification:

In this group, C-Sets (#C9Dc, #C9De, #C9Df, #C9Dc(Si) and #C9Df(Si)) are used for classification. The detailed information about the C-Sets construction and the associated syntax rules are found in the Special rules of classification in C09D 101/00.

  • If C09D 149/00 relates to a composition and two or more polymers are present, classification is given in the form of C-Sets according to the relative weight percentage of the polymer constituents.
  • The polymer in majority is given a symbol as a base symbol, and the polymers in minority are given symbols as subsequent symbols in the form of C-Sets.
  • A single symbol is given according to the macromolecular constituent present in the highest proportion.
  • If all the constituents are present in equal weight percentage, the composition is classified according to each of these constituents.
  • In the case that several polymers can be in majority, separate C-Sets should be made based on each polymer in majority and its component(s) in minority.
  • Orthogonal indexing codes C08L 2201/00 - C08L 2555/86 are also given if applicable.

Example 1: A coating of a blend of 60 parts polyacetylene (C09D 149/00) and 40 parts polyamide (C08L 77/00) is classified as (C09D 149/00, C08L 77/00).

Example 2: A coating of a blend of 50 parts poly acetylene (C09D 149/00) and 50 parts polyamide (C09D 177/00) is classified as (C09D 149/00, C08L 77/00) and (C09D 177/00, C08L 49/00).

Example 3: A coating based on a composition of polyacetylene and containing CaCO3 is classified as (C09D 149/00, C08K 3/26). If this composition contains also a polyamide, then the classification will be (C09D 149/00, C08L 77/00, C08K 3/26).

Example 4: A coating based on a composition based on a first polyacetylene (C09D 149/00) and containing a second polyacetylene, a phenol and silica is classified as (C09D 149/00, C08L 49/00, C08K 5/13, C08K 3/36) and C08L 2205/025.

Example 5: A coating based on a composition containing a polyamide in majority, a polyester and a polyacetylene is classified as (C09D 177/00, C08L 67/00, C08L 49/00) and C08L 2205/03.

Example 6: Coatings of compositions containing two polymers of the same dot group, for example compositions of two polyacetylenes, are characterised by the orthogonal indexing code C08L 2205/025. The complete classification for such compositions therefore would be (C09D 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.)

Definition statement

This place covers:

Coating compositions, e.g. paints, varnishes, lacquers based on polymers (I) obtained by reactions forming a carbon-carbon bond in the main chain other than polymers (II) 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 polymers (I) are themselves classified in C08G 61/00-C08G 61/127. The coating compositions comprise either other macromolecular compounds and/or other ingredients.

Relationships with other classification places

Relationship with other subclasses of classes C08 and C09:

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

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

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 and subgroups. Compositions based on monomers of such polymers are also put in C08G 61/00 and subgroups.

Use or choice of inorganic or non-macromolecular organic materials as compounding agents are classified in C08K, any macromolecular components are classified in C08L.

Relationship with other main groups of the same subclass C09D:

Coating compositions based on polymers prepared by condensation reactions of aldehydes or ketones with phenols only are classified in groups C09D 161/04 - C09D 161/16, since C09D 161/00-C09D 161/34 takes preference. For the same reasons, coating compositions based on condensation polymers of aldehydes or ketones only are classified in C09D 161/02. Coating compositions 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 put in the appropriate groups, e.g. C09D 179/04 for polypyrroles formed from amines and polyketones. Coating compositions based on polyketones are classified in C09D 173/00.

Further aspects:

In cases where a coating composition 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 subclass C08K or as an additive in group C08J 3/00, e.g. C08J 3/24 for crosslinking agents or C09D 7/40. This may be in addition to classification in C09D 101/00-C09D 201/00.

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, 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

A condensation polymer is a polymer in which water or some other simple molecule is eliminated from 2 or more monomer molecules as they combine to form the polymer.

Definition statement

This place covers:

Coating compositions comprising macromolecular compounds obtained by reactions forming in the main chain of the macromolecule a linkage containing silicon with or without sulfur, nitrogen, oxygen or carbon only (Si-based macromolecular compounds in accordance with C08G 77/00 or "Si-based polymers" hereunder), e.g.

  • block- or graft-copolymers containing polysiloxane sequences (corresponding to group C08G 77/42) or
  • polymers in which at least two but not all the silicon atoms are connected by linkages other than oxygen atoms (corresponding to group C08G 77/48);

Coating compositions of derivatives of such polymers.

Coating compositions made form mixtures of different reactive silanes (sol-gel compositions) are classified in the respective subclass of C09D 183/00. It is assumed that in such mixtures there has always been formed a siloxane polymer via hydrolysis/condensation.

Relationships with other classification places

The groups for coating compositions are structured in analogy to the adhesive compositions C09J 183/00. All notes in C09J 183/00 apply for C09D 183/00.

Special rules of classification

The following symbols are given if applicable:

C08G 77/70 for every document which uses the MDTQ nomenclature in the claims or the examples;

C08G 77/80 for polysiloxanes having aromatic substituents such as phenyl side groups.

C-Sets classification:

In this group, multiple C-Sets, specifically C-Sets (#C9Dc, #C9Df, #C9Dc(Si), #C9Dc(Si)2, #C9Df(Si) and #C9Df(Si)2) are used for classification. The detailed information about the C-Sets construction and the associated syntax rules are found in the "Special rules of classification" of following places:

  • See C-Sets #C9Dc, #C9Df, #C9Dc(Si) and #C9Df(Si) in C09D 101/00
  • See C-sets #C9Dc(Si)2 and #C9Df(Si) 2 present in this group below.

C-Sets statement : #C9Dc(Si)2, #C9Df(Si)2

#C9Dc(Si)2, and #C9Df(Si)2 are a special use of #C9Dc and #C9Df, are applied for a composition comprising two or more Si-based polymers in accordance with C08G 77/00.

  • In groups C09D 183/02-C09D 183/16, the feature relating to a coating composition comprising one Si-based polymer in majority with one Si-based polymer in minority optionally with non Si-based polymer is classified in the form of C-Sets.
  • In #C9Dc(Si)2, the base symbol, representing the polymer in majority, is taken from the groups C09D 183/02-C09D 183/16, whereas the subsequent symbol(s) representing the Si-based macromolecular compound(s) in minority is (are) taken from the group C08L 83/00 and optionally from the groups C08L 1/00 - C08L 101/16 for any other polymer .
  • In #C9Df(Si)2, the base symbol, representing the polymer in majority, is taken from the groups C09D 183/02-C09D 183/16, whereas the subsequent symbol(s) representing the Si-based macromolecular compound(s) in minority is (are) taken from the group C08L 83/00 and optionally from the groups C08L 1/00 - C08L 101/16 for any other polymer and further subsequent symbols representing compound(s) used as an additive(s), is (are) taken from the groups C08K 3/00 - C08K 13/08.

  • A single symbol is given according to the macromolecular constituent present in the highest proportion.

C-Sets syntax rules:

  • C-Sets of #C9Dc(Si)2 shall contain at least two symbols.
  • C-Sets of #C9Df(Si)2 shall contain at least three symbols.
  • While duplicate symbols are allowed in these C-Sets, only one symbol selected from the range C09D 183/02-C09D 183/16 is permitted per C-Set.
  • The order of C09D and C08L symbols in C-Sets of #C9Dc( Si)2 is relevant as it reflects the relative amounts of the polymers.
  • In #C9Df(Si)2, the C08K symbols for the additives always appear after the symbols for the polymers (C09D or C08L). The order of C08K symbols of additives is not relevant if there is more than one additive in the composition.
