Patent ID: 8211544

Claim:
A surface modifier comprising an organosilicone compound represented by General Formula (A) and/or General Formula (B): F—(CF 2 ) q —(OCF 2 CF 2 CF 2 ) m —(OC 2 F 4 ) n —(OCF 2 ) o (CH 2 ) p X(CH 2 ) r Si(X′) 3-a (R 1 ) a (A) wherein q is an integer from 1 to 3; m, n, and o are independently integers from 0 to 200, provided that the sum of m, n, and o is 5 or greater; p is 1 or 2; X is O; r is 3; R 1 is a C 1-22 linear or branched hydrocarbon group; a is an integer from 0 to 2; and X′ is hydrolysable group; and wherein Rf is F—(CF 2 ) q —(OC 3 F 6 ) m —(OC 2 F 4 ) n —(OCF 2 ) o (CH 2 ) p X(CH 2 ) r —, wherein q is an integer from 1 to 3; m, n, and o are independently integers from 0 to 200, provided that the sum of m, n, and o is 5 or greater; p is 1 or 2; X is O; r is 3; R 1 is a C 1-22 linear or branched hydrocarbon group; a is an integer from 0 to 2; X′ is hydrolysable group; and z is an integer from 0 to 10 when a is 0 or 1.
