PAT 87 134 27.03.1987 Curable composition based on branched acrylates with COOH groups and/or branched acrylates with epoxide groups, and aminoplast resins. The present invention relates to a curable composition consisting of A) a polymer with at least 2 COOH groups, B) a polymer with at least 2 epoxide groups and C) an aminoplast resin. At least one of components A) or B) is based on a branched soluble acrylate copolymer, more than 3 to 30% by weight, based on the total weight of the monomers, of a monomer with at least two polymerizable, olefinically unsaturated double bonds being used in the preparation of these branched acrylate copolymers and the proportions of the individual components relative to one another being chosen so that a molar ratio of 3:1 to 1:3 prevails between the carboxyl groups of component A) and the epoxide groups of component B) and a weight ratio of 65:35% by weight to 98:2% by weight prevails between the epoxy resin component and the aminoplast resin component. The invention also relates to coating agents based on the curable composition.
