ABSTRACT:
Epoxy ester copolymer dispersible in water with the aid of an amine, which may be ammonia, is provided by esterifying a polyepoxide having a 1,2-epoxy equivalency in excess of 1.0 and a molecular weight of from 350 to 8000 with at least 0.5% of the weight of the copolymer of a monoester of a saturated monohydric alcohol with a monoethylenically unsaturated dicarboxylic acid which resists homopolymerization. This polyepoxide ester is copolymerized with from 15% to 70% of monoethylenic monomers, based on the weight of the copolymer, these monoethylenic monomers including carboxyl functional monomer providing an acid number of from 20-150 in the copolymer.
