Abstract: The invention relates to a soluble, crosslinkable acrylate copolymer which is obtainable by copolymerization of more than 3 to 30% by weight of monomers having at least two polymerizable, olefinically unsaturated double bonds, from 5 to 50% by weight of monomers having a cross-linkable group, with the exception of hydroxyl groups and carboxyl groups, and from 20 to 92% by weight of further monomers having a polymerizable, olefinically unsaturated double bond, the sum of the monomers being 100% by weight. The invention furthermore relates to processes for the preparation of acrylate copolymers and coating agents based on the acrylate copolymers according to the invention.

Abstract: The invention relates to a hydroxylic acrylate copolymer which contains a proportion of copolymerized monomers having at least 2 double bonds, and to the process for the preparation of the acrylate copolymer. The invention also relates to coating agents which contain acid-curable binders, organic solvents and, if appropriate, pigments, fillers and conventional assistants and additives and which contain, as the essential binder, the hydroxylic acrylate copolymer and an alkylated melamine/formaldehyde resin. The invention also relates to coating agents which, as the essential binders, contain the hydroxylic acrylate copolymer in one or more different polyfunctional isocyanates.

Abstract: 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.
