Abstract:
A heat-curable aqueous composition, comprising at least one polymer (A1), which contains from 0 to 5% by weight of an &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid in copolymerized form and which is obtained by free-radical polymerization in the presence of(a) at least one polymer (A2) obtained by free-radical polymerization and containing from 15 to 100% by weight of an &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid in copolymerized form, and (b) at least one amine comprising at least one long chain having at least six carbons, wherein the weight ratio (based on solids) of polymer (A1) to polymer (A2) is from 7:1 to 1:7 and that of polymer (A2) to long-chain amine is from 20:1 to 2:1.
