Abstract
A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes an emulsion-polymerized latex copolymer having copolymer chains of one or more mono-unsaturated monomers that are cross-linked with one or more multi-unsaturated monomers. The method also includes heating the sprayed coating composition to cure the coating composition, thereby providing the coating on the interior surface of the food or beverage container.
