The present invention is to provide a novel polymerizable chiral compound (chiral agent) having high left-handed helical twisting power, a polymerizable liquid crystal composition comprising the polymerizable chiral compound and a polymerizable liquid crystal compound, a liquid crystal polymer, and an optically anisotropic body. The object was achieved by a left-handed-helix-inducing polymerizable chiral compound represented by the following formula (I), a polymerizable liquid crystal composition comprising the polymerizable chiral compound and a polymerizable liquid crystal compound, a liquid crystal polymer and an optically anisotropic body:
wherein X represents the following formula (X-i) or (X-ii) wherein * represents a bond:
wherein Y1 to Y6 are each one selected from the group consisting of -O-, -S-, -O-C(=O)-, -C(=O)-O- and so on; Yx is one selected from the group consisting of -C(=O)-, -O-C(=O)-, -CH=CH-C(=O)-, -CH 2 - and so on; Yz is one selected from the group consisting of -C(=O)-, -C(=O)-O-, -C(=O)-CH=CH- and so on; G1 and G2 are each a divalent aliphatic group which has 1 to 20 carbon atoms and which may have a substituent; Z1 and Z2 are each an alkenyl group which has 2 to 10 carbon atoms and which may be substituted by a halogen atom; Q1 to Q4 are each a hydrogen atom or an alkyl group which has 1 to 6 carbon atoms and which may have a substituent; A1 to A6 are each a divalent organic group having 1 to 30 carbon atoms; and a and b are each 0 or 1. |
