摘要

PCT No. PCT/AT94/00203 Sec. 371 Date Jun. 24, 1996 Sec. 102(e) Date Jun. 24, 1996 PCT Filed Dec. 22, 1994 PCT Pub. No. WO95/17450 PCT Pub. Date Jun. 29, 1995A process is disclosed for preparing water-dilutable, acrylate copolymer-based lacquer binders. A polycarboxylic component is reacted with an epoxide group-containing polyhydroxylic component, and the carboxylic groups are then at least partially neutralized. As epoxide group-containing monomers for the polyhydroxylic components, glycidyl(meth)acrylate and/or glycidylallylether are used in proportions from 0.1 to 3% by weight. Associated with cross-linking components and if required with other lacquer binders, these lacquer binders are suitable for producing water-dilutable baking enamels with a low auxiliary organic solvent content.
