Patent ID: 7311949

Claim:
A composition comprising at least one polymer having at least one fluoro-aliphatic group and at least one hydrophilic group selected from the group consisting of a carboxyl group (—COOH), a sulfo group (—SO 3 H), a phosphonoxy group {—OP(═O)(OH) 2 } and salts thereof in side chain and at least one liquid crystal compound, wherein the polymer comprises at least one repeating unit derived from a monomer having at least one fluoro-aliphatic group, represented by a formula (A1): wherein R 11 represents a hydrogen atom or a methyl group; X represents an oxygen atom, a sulfur atom or —N(R 12 )— where R 12 represents a hydrogen atom or a C 1-4 alkyl group; H f represents a hydrogen atom or a fluorine atom; m is an integer from 1 to 6 and n is an integer from 2 to 4.
