Patent ID: 8907002

Claim:
A coating composition comprising a vinyl acrylic copolymer latex, wherein said copolymer latex has a water contact angle of about 60° or higher on the dried latex film surface, wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm 2 /mm/24 hr, wherein said copolymer latex comprises a polymer having Formula I wherein the vinyl acetate is present at about 60 to about 90% by weight of the polymer, the butyl acrylate is present at about 5 to about 30% by weight of the polymer, the vinyl ester of versatic acid 10 is present at about 5 to about 20% by weight of the polymer, the sodium vinyl sulfonate is present at about 0.05 to about 0.5% by weight of the polymer, and the N-(2- methacryloyloxyethyl) ethylene urea is present at about 0.5% to about 1.5% by weight of the polymer, and wherein x=1-15, p=1-10, n=12-200, m=30-500, and k=120-2000.
