Patent ID: 6881782

Claim:
A latex paint composition comprising (a) a polymer having interpolymerized units that comprise units derived from styrene, methyl styrene, vinyl, or combinations thereof and units derived from one or more acrylates, methacrylates, acrylonitrile, or combinations thereof; (b) hiding pigment; (c) non-cellulosic thickener; and (d) a polyfluorourethane additive that is the reaction product of: (i) at least one isocyanate reactant selected from the group consisting of diisocyanates, polyisocyanates, or mixtures of polyisocyanates containing at least three isocyanate groups per molecule, (ii) at least one fluorochemical compound containing at least one Zerewitinoff hydrogen in an amount sufficient to react with about 5% to about 80% of the isocyanate groups in said diisocyanate, and (iii) at least one non-fluorinated compound represented by the formula R 10 —(R 2 ) k —YH in an amount sufficient to react with about 5% to about 80% of the isocyanate groups in said diisocyanate or polyisocyanate wherein R 10 is a C 1 -C 18 alkyl, C 2 -C 18 omega-alkenyl, or C 2 -C 18 omega-alkenoyl; R 2 is —C n H 2n — optionally end-capped by —[OCH 2 C(R 4 )H] p —, —[OCH 2 C(CH 2 Cl)H] p —, or —C(R 5 )(R 6 )(OCH 2 C[CH 2 Cl]H) p — wherein R 4 , R 5 , and R 6 are each independently H or a C 1 -C 6 alkyl, n is 0 to about 12, p is 1 to about 50; Y is O, S, or N(R 7 ) wherein R 7 is H or C 1 -C 6 alkyl; and k is 0 or 1; wherein said latex paint composition has a pigment volume concentration of at least 20% and less than its critical pigment volume concentration.
