Soluble acrylate copolymer containing carboxyl groups, processes for its preparation and coating agents based on the acrylate copolymer

摘要

The invention relates to a soluble acrylate copolymer which can be obtained by copolymerization of more than 3 to 30% by weight, based on the total weight of all the monomers, of a monomer with at least 2 polymerizable, olefinically unsaturated double bonds, monomers which carry functional groups and other monomers with a polymerizable double bond, the acid number of the acrylate resin being 15 to 200. The invention furthermore relates to processes for the preparation of the acrylate copolymers and coatings based thereon and based on polyepoxides.
