Patent ID: RE39423

Claim:
A curable coating composition comprising : 1) a first monomer represented by formula (A) RfOCOC(R)═CH 2 (A) wherein Rf represents a linear or branched fluorinated alkyl group having not less that than 6 carbon atoms, a hydroxyl substituted fluorinated alkyl having not less that than 6 carbon atoms, a fluorinated sulfonamide having not less that than 6 carbon atoms, or a fluorinated amide having not less that than 6 carbon atoms, and R represents H . , F, or C 1-10 fluorinated alkyl; 2) a second monomer represented by formula (B) Rf′OCOC(R′)═CH 2 (B) wherein Rf′ represents a linear or branched C 1-5 fluorinated alkyl and R′ represents —H, —F, or —CH 3 ; and 3) at least one polyfunctional methacrylic curable monomer, wherein the weight ratio of the first monomer to the second monomer is from 75:25 to 99:1.
