    Abstract: The present invention relates to a method of coating a food or beverage can, the method comprising: forming a composition comprising an emulsion polymerized latex polymer, comprising: forming a salt of an acid- or anhydride-functional polymer and an amine in a carrier comprising water to form an aqueous dispersion; combining an ethylenically unsaturated monomer component with the aqueous dispersion; and polymerizing the ethylenically unsaturated monomer component in the presence of the aqueous dispersion to form an emulsion polymerized latex polymer; and applying the composition comprising the emulsion polymerized latex polymer to a metal substrate prior to or after forming the metal substrate into a food or beverage can or portion thereof. The present invention also relates to a food or beverage can having a coating composition disposed thereon and to a composition for use as a coating of a food and beverage can.
