Definition statement

This subclass 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 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.

Relationship between large subject matter areas

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 7/12. This may be in addition to classification in C09D 101/00-C09D 201/00.

Special rules of classification

In this subclass, coating compositions, containing specific organic macromolecular substances are classified only according to the macromolecular substance, non-macromolecular substances not being taken into account.

Example: a coating composition containing polyethene and amino-propyltrimethoxysilane is classified in group C09D 123/06.

However, coating compositions containing combinations of organic non-macromolecular compounds having at least one polymerisable carbon-to-carbon unsaturated bond with prepolymers or polymers other than unsaturated polymers of groups C09D 159/00-C09D 187/00 are classified according to the unsaturated non-macromolecular component in group C09D 4/00.

Example: a coating composition containing polyethene and styrene monomer is classified in group C09D 4/00.

Aspects relating to the physical nature of the coating compositions or to the effects produced, as defined in group C09D 5/00, if clearly and explicitly stated, are also classified in this subclass.

Coating compositions characterised by other features, e.g. additives, are classified in group C09D 7/00, unless the macromolecular constituent is specified.

In this subclass, coating compositions comprising two or more macromolecular constituents are classified according to the macromolecular constituent or constituents present in the highest proportion, i.e. the constituent on which the composition is based. If the composition is based on two or more constituents, present in equal proportions, the composition is classified according to each of these constituents.

Example: a coating composition containing 80 parts of polyethene and 20 parts of polyvinylchloride is classified in group C09D 123/06. A coating composition containing 40 parts of polyethene and 40 parts of polyvinylchloride is classified in groups C09D 123/06 and C09D 127/06.

In groups C09D 101/00-C09D 201/00, any macromolecular constituent of a coating composition which is not identified by the classification according to Note (3) after the title of subclass C09D, and the use of which is determined to be novel and non-obvious, must also be classified in a group chosen from groups C09D 101/00-C09D 201/00.

Any macromolecular constituent of a coating composition which is not identified by the classification according to Note (3) after the title of subclass C09D or the Note above, and which is considered to represent information of interest for search, may also be classified in a group chosen from groups C09D 101/00-C09D 201/00. This can for example be the case when it is considered of interest to enable searching of coating compositions using a combination of classification symbols. Such non-obligatory classification should be given as additional information.

In groups C09D 123/00-C09D 149/00, in the absence of an indication to the contrary, a copolymer is classified according to the major monomeric component.

In groups C09D 165/00-C09D 185/00, in the absence of an indication to the contrary, coating compositions based on macromolecular compounds obtained by reactions forming two different linkages in the main chain are classified only according to the linkage present in excess.
