Abstract

The present invention relates to a polymer dispersion which comprises a highly branched polycarbonate having unsaturated fatty acid groups. The invention further relates to highly branched polycarbonates having groups deriving from unsaturated fatty acids, to a process for preparing such highly branched polycarbonates, and to the use of these highly branched polycarbonates for improving the curing properties of coating compositions based on an aqueous acrylate dispersion.
