Abstract
An aqueous protective coating composition particularly useful for can coatings is based on a polymeric binder comprising epoxy crosslinked microgel particles. The microgel polymer is produced by dispersing into water a carbon grafted, carboxyl functional acrylic-epoxy copolymer, and combined with low molecular weight diepoxide, followed by coreaction and crosslinking between the carboxyl copolymer and diepoxide to form stable aqueous dispersed microgel particles.
