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.
Claims98
1-20. (canceled)
An inside spray beverage can coating composition, comprising:
- an emulsion polymerized latex polymer that is prepared from ingredients including:
- a salt of an acid- or anhydride-functional acrylic polymer and an amine;
- an ethylenically unsaturated monomer component that includes a vinyl aromatic compound and an oxirane-group containing monomer;
- and
- water;
- wherein the coating composition is substantially free of bound bisphenol A, and wherein the coating composition is suitable for forming an inside spray coating of a two-piece drawn and ironed aluminum beverage can.

An inside spray beverage can coating composition, comprising:
- an emulsion polymerized latex polymer, wherein the emulsion polymerized latex polymer is substantially free of bound bisphenol A and bound aromatic glycidyl ether compounds and is prepared from ingredients including:
- a salt of an organic-solution polymerized acid- or anhydride-functional acrylic polymer and a tertiary amine,
- an ethylenically unsaturated monomer component that includes an alkyl (meth)acrylate, a glycidyl ester of an alpha, beta-ethylenically unsaturated acid or anhydride, and a vinyl aromatic component that is at least 20 wt-% of the ethylenically unsaturated monomer component, and wherein the vinyl aromatic component comprises one or more aromatic compounds, and
- water;
- and
- a phenoplast crosslinker;
- wherein the coating composition is substantially free of bound bisphenol A, and wherein the coating composition is suitable for forming an inside spray coating of a two-piece drawn and ironed aluminum beverage can.

An inside spray beverage can coating composition, comprising:
- an emulsion polymerized latex polymer, and wherein the emulsion polymerized latex polymer is prepared from ingredients including:
- a salt of an organic-solution polymerized acid- or anhydride-functional acrylic polymer and a tertiary amine, wherein the polymerizable unsaturated monomers used to generate the organic-solution polymerized acid- or anhydride-functional acrylic polymer include ethyl acrylate, methacrylic acid, and styrene,
- an ethylenically unsaturated monomer component that includes glycidyl methacrylate, styrene, and an alkyl (meth)acrylate, wherein at least 50 wt-% of the ethylenically unsaturated monomer component is used in making the latex polymer, based on the total weight of ethylenically unsaturated monomer component and salt of the organic-solution polymerized acid- or anhydride-functional acrylic polymer, and
- water;
- wherein the coating composition is substantially free of bound bisphenol A, and wherein the coating composition is suitable for forming an inside spray coating of a two-piece drawn and ironed aluminum beverage can.
