A B S T R A C T The invention relates to a resin composition comprising a mixture of resins, a first resin of which consists of the reaction product of an epoxidized fatty acid ester of a polyvalent alcohol with a carboxylic acid and a second resin consists of an ester of a polyva-lent alcohol, modified with carboxylic acid. The resin mixture, moreover, contains an unsaturated polyester resin having a molecular weight of 1200-20,000 per double bond and an acid number of 5-50, between 50% and 90% of the unsatura-tion being formed by a semi-ester of an .alpha.,.beta.-unsaturated dicarboxylic acid. |
