Summary: | The present invention relates to an article, comprising a food or beverage container, or a portion thereof, including: a metal substrate; and a coating disposed on at least a portion of the metal substrate, wherein the coating is formed from a coating composition having an emulsion polymerized latex hat is a reaction product of a method comprising:emulsion polymerizing first-stage monomers in an aqueous carrier to produce a first-stage copolymer, wherein the first-stage monomers include greater than 3% by weight of step-growth- functional monomers having step-growth- functional groups, based on an entire weight of the first-stage monomers; and emulsion polymerizing second-stage monomers in the presence of the first-stage copolymer to form a second-stage copolymer;wherein the coating composition is substantially free of structural units derived from (meth)acrylamide-type monomers and bisphenol A. |
