An emulsion core/shell polymer produced by two-stage emulsion copolymerization of monomers where the first stage monomers comprising alkylol acrylamide, functional monomer, and other ethylenic monomers, wherein the alkylol acrylamide and functional monomer are adapted to cross-link to provide a minor amount of cross-linking in the core. The Tg of the core is above 40C and the Tg of the shell is below 20C. The core/shell polymer is used in coating particularly useful as end coatings for ends of beverage containers. |
