ABSTRACT:
The invention pertains to coating compositions comprising self-curing water-dispersed polymers, epoxy-acrylic copolymers, and preferably including epoxy phosphate polymers. The self-curing water-dispersed polymers produced preferably by step-wise polymerization of ethylenically unsaturated monomers comprising alkylol acrylamide monomer, functional monomers, and other monomers, wherein the alkylol acrylamide monomers are copolymerized in the second stage monomer addition to preferentially locate alkylol acrylamide groups in the surface portion of the latex polymer particles. Melamine resins can be added to improve the cure properties of the coating composition. The coating compositions are advantageously sprayable compositions and are particularly useful for interior coatings for food and beverage containers.
