Patent ID: 8318848

Claim:
A coating composition comprising: (A) an aqueous dispersion of particles made from a copolymer comprising, based on the weight of the copolymer: (i) 97.5-99.3 parts by weight of polymerized units of one or more monoethylenically unsaturated monomers; (ii) 0.1-1.0 parts by weight of polymerized units of a carboxylic acid functional or anionic monomer; and (iii) 0.6-1.5 parts by weight of polymerized units of a phosphorus-containing monomer; and where the dispersion further comprises 0.5-5.0 parts by weight, in relation to parts of copolymer, of an nonionic surfactant containing —(CH 2 —CHRO) z —X groups, where R=H or CH 3 , z=3-60, and X is a nonionic functionality, wherein said —(CH 2 —CHRO) z —X groups are adsorbed onto the surface of the particles; and (B) titanium dioxide.
