Patent ID: 7425374

Claim:
A coatable composition comprising: a) water; b) a film-forming organic polymer; and c) a leveling agent represented by the formula: R f —SO 2 —N(R)—CH 2 CH(OX′)CH 2 -Q-X wherein R f is selected from the group consisting of C 2 to C 6 perfluoroalkyl groups; R is selected from the group consisting of H and a C 1 to C 18 alkyl group; each Q is independently selected from the group consisting of O and S; X is selected from the group consisting of —(C(═O)—(CH 2 ) a -Q) b -M, —((CH 2 ) a —C(═O)-Q) b -M, and —(C(═O)—(CH 2 ) a -Q) b —CH 2 CH(OX′)—CH 2 N(R)SO 2 R f ; wherein M is selected from the group consisting of H and a cation; each a is independently selected from 1 to 5 and each b is independently selected from 1 to 4; and X′ is selected from the group consisting of H and X.
