Abstract
An aqueous dispersed acrylic grafted epoxy-ester polymer useful as a polymeric binder for protective coatings is produced by first forming a carboxyl functional epoxy-ester by esterifying a low molecular weight epoxy resin with a low molecular weight, unsaturated, carboxyl terminated polyester, followed by in-situ copolymerizing ethylenic monomers in the presence of water-dispersed epoxy-ester.
