Coating compositions from dicyclopentenyl acrylate and/or methacrylate

A composition according to claim 8 in which the component (2) is selected from the group of acrylic acid or methacrylic acid esters of the subgroup (a) recited in claim 16.

An autoxidizable composition adapted to be used for coating and/or impregnating a substrate comprising a) reactive non-volatile monomeric material comprising at least a predominant proportion of one of dicyclopentenyl acrylate and dicyclopentenyl methacrylate and b) a drying oil-modified polyol/polycarboxylic acid polyester resin dissolved therein, the polycarboxylic acid component of the polyester being predominantly to exclusively an aliphatic dicarboxylic acid having at least 4 carbon atoms, the carboxyl groups being separated by a hydrocarbon group having at least 2 carbon atoms.

An autoxidizable composition adapted to be used for coating and/or impregnating a substrate comprising:

• a. a reactive monomeric material comprising a mixture of a predominant proportion of DCP(M)A and a minor proportion of an ester of an aliphatic alcohol having 10 to 20 carbon atoms with acrylic acid or methacrylic acid or a dialkyl fumarate, maleate, or itaconate in which the alkyl groups are selected from (C.sub.1 to C.sub.8) alkyl groups, and
• b. an oil-modified polyol-polycarboxylic acid alkyd or polyester resin dissolved therein, the polycarboxylic acid precursor of the alkyd comprising a predominant to exclusive proportion of an aromatic dicarboxylic acid or anhydride,
• the relative proportions between a) and b) being 15 to 75% by weight of a) and 85 to 25% of b) respectively.

An autoxidizable composition adapted to be used for coating and/or impregnating a substrate comprising:

• a. reactive non-volatile monomeric material comprising at least a predominant proportion of one of dicyclopentenyl acrylate and dicyclopentenyl methacrylate and
• b. a polyol/polycarboxylic acid polyester resin having at least one unsaturated component dissolved in a), the polycarboxylic acid component of the polyester being predominantly to exclusively an aliphatic dicarboxylic acid having at least 4 carbon atoms and having a hydrocarbon group of at least 2 carbon atoms extending between the carboxyl groups, said acid component comprising an .alpha.,.beta.-ethylenically unsaturated aliphatic dicarboxylic acid, at least part of the curing functionality in the resin being attributable to the last-mentioned diacid component.
