Patent ID: 7575696

Claim:
A liquid crystal composition, comprising at least one compound represented by formula (I) and at least one compound represented by formula (II): Q1-SP1-X1-MG-X2-SP2-Q2 Formula (I) wherein Q1 and Q2 each independently represent an ethylenically unsaturated polymerizable group, SP1 and SP2 each independently represent a divalent linking group selected from the group consisting of —O—, —S—, —CO—, —NR′—(R′ represents an alkyl group having 1 to 7 carbon atoms, or a hydrogen atom), a divalent chain group and a group made by any combination of two or more thereof, X1 and X2 each independently represent a single bond, —O—, —CO—O—, —O——CO—, —CO—NH—, —NH—CO— or —O—CO—O—, and MG is represented by formula (MG-1): -(A1-Z 1 )m-A2-Z 2 -A3- Formula (MG-1) wherein A1, A2 and A3 each independently represent a 1,4-phenylene group, a heterocyclic group in which one, or two or more CH groups of a 1,4-phenylene group have been replaced by a nitrogen atom (N), a 1,4-cyclohexylene group, a heterocyclic group in which one CH 2 group, or two CH 2 groups that are not adjacent to each other of a 1,4-cyclohexylene group have been replaced by an oxygen atom (O) and/or a sulfur atom (S), a 1,4-cyclohexenylene group, or a naphthalene-2,6-diyl group, each of which may have a substituent; Z 1 and Z 2 each independently represent —COO—, —OCO—, —CH 2 CH 2 —, —OCH 2 —, —CH 2 O—, —CH═CH—, —C≡C—, —CH═CH—COO—, —OCO—CH═CH— or a single bond; and m represents an integer of 0, 1 or 2, and wherein R a , R b and R c each independently represent -L 1 -R 1 , -L 2 -R 2 or —NHR; at least one of R a , R b and R c is —NHR; L 1 and L 2 each independently represent a single bond or a divalent linking group; R 1 and R 2 each independently represent a hydrogen atom or a substituent; and R represents a group having a polymerizable group.
