    摘要: An inside spray coating composition comprising:
    an aqueous carrier; and
    an emulsion-polymerized latex copolymer dispersed in the aqueous carrier, and comprising:
    one or more mono-unsaturated monomers each having a single ethylenically-unsaturated group; and
    one or more multi-unsaturated monomers each having two or more ethylenically-unsaturated groups, wherein the multi-unsaturated monomer(s) each have a divalent chain length with at least two carbon atoms between at least two of the ethylenically-unsaturated groups, and constitute from 8% by weight to 25% by weight of the monomers used to produce the emulsion-polymerized latex copolymer;
    wherein the coating composition preferably includes less than 1 weight percent, if any, of vegetable oils;
    wherein the coating composition has an average viscosity ranging from about 5 seconds to about 40 seconds, pursuant to the Viscosity Test; and
    wherein the coating composition has a resin solids content ranging from about 10% by weight to about 30% by weight, based on a total weight of the coating composition.

    摘要: 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.
