Composition comprising ester of epoxy, unsaturated fatty acid dimer or trimer and acid containing addition polymer, and aqueous coating compositions prepared therefrom

摘要

Non-gelled compositions containing hydroxy ester copolymer having carboxyl groups and substantially free of oxirane groups are disclosed which are the esterification reaction product of (a) acidic addition copolymer; and (b) a polyepoxide which has been partially defunctionalized by reaction with a dimer or a trimer of a fatty acid. The resulting composition is neutralized with amine, is self-emulsifiable in water and is useful for coatings.
