Abstract
The invention pertains to aqueous dispersed, crosslinked microgel polymers useful as a polymeric binder in protective coatings. The microgel polymeric binder comprises epoxy-acrylic graft copolymer dispersed into water, emulsion copolymerized monoethylenically unsaturated monomer, and emulsion copolymerized divinyl benzene adapted to crosslink in the emulsion copolymerization step with the monoethylenic monomers to produce the crosslinked microgel polymer particles. The microgel polymer is particularly useful as binder for can coatings adapted to be heat cured to form a protective film.
