Claim:
1. An actinically-polymerizable amphiphilic polysiloxane of formula (1) or (2) in which: ν1, ν2, and ω1 independently of one another are an integer of from 1 to 500; ω2 independent of each other are an integer of from 1 to 10; R R R L in which R 18 is a substituted or unsubstituted C 1 -C 10 alkylene divalent radical and R 18 ′ is a direct bond or a substituted or unsubstituted C 1 -C 10 alkylene divalent radical, X 1 is a direct bond, a thio ether bond (—S—), —NR 20 — in which R 20 is a substituted or unsubstituted C 1 -C 10 alkyl, or a divalent radical of in which R 19 is a substituted or unsubstituted C 1 -C 10 alkylene divalent radical and R 20 is a substituted or unsubstituted C 1 -C 10 alkyl; L E in which r1 and r2 independent of each other are integer of 0 or 1, R″ is hydrogen or methyl, R 21 is a substituted or unsubstituted C 1 -C 10 alkylene divalent radical, X 2 is in which R 22 and R 23 independent of each other are C 1 -C 8 alkyl, and R 19 is a substituted or unsubstituted C 1 -C 10 alkylene divalent radical, provided that either (i) E 1 and E 2 both are a polymerizable group or (ii) E 3 is a polymerizable group; and hPC is a hydrophilic polymer segment selected from the group consisting of (1) polyoxazoline segment in which R 1 is hydrogen, methyl or ethyl group, and q is an integer from 3 to 500) which is obtained in a ring-opening polymerization of oxazoline, (2) a polypeptide segment composed of at least one amino acid selected from the group consisting of asparagine, glutamine, alanine, glycine, and combinations thereof, and (3) a hydrophilic polymer segment composed of hydrophilic monomeric units derived from at least one hydrophilic vinylic monomer selected from the group consisting of (meth)acrylamide, N,N-dimethyl (meth)acrylamide, dimethylaminoethyl (meth)acrylate, dimethylaminoethyl (meth)acrylamide, N-vinyl-2-pyrrolidone, N-vinyl-N-methyl isopropylamide, N-vinyl-N-methyl acetamide, N-vinyl formamide, N-vinyl acetamide, N-vinyl isopropylamide, N-vinyl-N-methyl acetamide, N-methyl-3-methylene-2-pyrrolidone, 1-ethyl-3-methylene-2-pyrrolidone, 1-methyl-5-methylene-2-pyrrolidone, 1-ethyl-5-methylene-2-pyrrolidone, 5-methyl-3-methylene-2-pyrrolidone, 5-ethyl-3-methylene-2-pyrrolidone, 1-n-propyl-3-methylene-2-pyrrolidone, 1-n-propyl-5-methylene-2-pyrrolidone, 1-isopropyl-3-methylene-2-pyrrolidone, 1-isopropyl-5-methylene-2-pyrrolidone, 1-n-butyl-3-methylene-2-pyrrolidone, 1-tert-butyl-3-methylene-2-pyrrolidone, and mixtures thereof.
