Curable composition based on branched acrylates with carboxyl groups and/or branched acrylates with epoxide groups and aminoplast resins

摘要

Curable composition based on branched acrylates with COOH groups and/or branched acrylates with epoxide groups, and aminoplast resins. PPThe present invention relates to a curable composition consisting ofPPA) a polymer with at least 2 COOH groups, PPB) a polymer with at least 2 epoxide groups andP PC) an aminoplast resin.PPAt 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.PPThe invention also relates to coating agents based on the curable composition.
