Abstract:
A coating composition for a food or beverage can that includes an emulsion polymerized latex polymer formed by combining an ethylenically unsaturated monomer component with an aqueous dispersion of a water-dispersible polymer.

Claim (Index 21):
A method, comprising the steps of:\n providing a latex-based acrylic coating composition that comprises a surfactant, a crosslinker, and a latex; wherein the latex includes one or more polymers formed from ethylenically unsaturated monomers; wherein the ethylenically unsaturated monomers include one or more monomers selected from alkyl acrylates and methacrylates, one or more acid-functional monomers, optionally one or more oxirane-group containing monomers, and optionally one or more difunctional (meth)acrylate monomers; wherein acrylamide, methacrylamide, N-isobutoxymethyl acrylamide, or N-butoxymethyl acrylamide are not present in ethylenically unsaturated monomers polymerized in aqueous medium to form the latex; and wherein the coating composition is not made using PVC compounds and is substantially free of mobile and bound bisphenol A; spray applying the coating composition onto an interior surface of an aluminum beverage can including a body portion and an end portion; and curing the coating composition to form a cured coating that exhibits (i) a global extraction result of less than 50 ppm and (ii) a metal exposure of less than 3 mA on average when the can is filled with 1% NaCl in deionized water and tested pursuant to the Initial Metal Exposure test method disclosed herein.
