Patent ID: 8158713

Claim:
A coating composition comprising: (A) an aqueous dispersion of thermoplastic copolymer particles comprising: (i) 0.5-2.0% by weight of the copolymer of phosphorus-containing monomers, in polymerized form; and (ii) at least 20% by weight of the copolymer of one or more monomers, in polymerized form, selected from the group consisting of ethyl acrylate, methyl acrylate, and combinations thereof; and (iii) 0.5 to 5.0% by weight of the copolymer of a beta-dicarbonyl monomer or a cyanocarbonyl monomer, in polymerized form; and (iv) up to 74.5% by weight of the copolymer of one or more mono-ethylenically unsaturated monomers, in polymerized form, excluding monomers (i), (ii) and (iii); and (B) one or more opacifying colorants.
