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.

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.

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:

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).

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 definition 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.

Coating compositions that are characterized by the polymeric binder are to be classified in groups C09D 101/00 - C09D 201/00.

Further subdivisions:

C09D 5/002

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.

C09D 5/008

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.

C09D 5/02

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

C09D 5/027

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

C09D 5/035

When powder coatings are characterized by the colouring agent, or the special effect of the produced film.

C09D 5/032 takes precedence over this group.

C09D 5/04

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.

C09D 5/14

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.

C09D 5/16

C09D 5/165

Paints containing hydrolysable groups.

C09D 5/1643 takes precedence over this group.

Coatings having a metallic effect without colour interference.

C09D 5/44

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.

Paints showing spontaneous emission of radiation originating from an electronically or vibrationally excited species not in thermal equilibrium with its environment.

Luminescent materials per se are covered by C09K 11/00.

Special processes for incorporating ingredients e.g. incorporating colour pastes in a base paint.

C09D 7/43 and C09D 7/40 are combined with ICO-codes C08K and C08L to further specify the "thickening agent" respectively the "other additive" in the coating composition.

Correcting fluids, i.e. liquid covering of ink, usually in the same colour as the background.

Inks, i.e. pigmented liquids, e.g. printing inks, writing inks, sympathetic, colour changing or electrically conductive inks

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.

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.

Classification guidance:

When a document specifies coating of polyacetal in general, or both homopolyacetals and copolyacetals, classification is done in the main group C09D 159/00 only when the document specifically mentions homopolyacetals or copolyacetals, then classification in C09D 159/02 or C09D 159/04 is given.

Example 1: A coating composition comprising a blend of 60 parts non-specified epoxy resin (C09D 163/00) and 40 parts polyamide (C08L 77/00) is classified as (C09D 163/00, C08L 77/00).

Example 2: A coating composition comprising a blend of 50 parts non-specified epoxy resin (C09D 163/00) and 50 parts Novolak epoxy resin (C09D 163/04) is classified as (C09D 163/00, C08L 63/04), (C09D 163/04, C08L 63/00) and C08L 2205/02.

Coating compositions comprising macromolecular unsaturated compounds, which are epoxidised in a further step, e.g. oxidation by H₂O₂, such as fatty acid-based polymers or epoxidized rubbers

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

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.

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.
