Patent ID: 8512597

Claim:
A polymerizable optically-active imide compound represented by general formula (I): wherein, rings A 1 , A 2 , A 3 , and A 4 each independently represent a benzene ring or a naphthalene ring, wherein a carbon atom in the benzene ring and the naphthalene ring may optionally be substituted by a nitrogen atom; M 1 and M 2 each independently represent a hydrogen atom or a methyl group; R 1 represents a C 1-10 alkyl group, a C 6-20 aryl group, or a C 7-20 arylalkyl group; a hydrogen atom in R 1 may optionally be substituted by a halogen atom; a methylene group in R 1 may be interrupted by —O—, —COO—, or —OCO—; X 1 represents a direct bond, -L 1 -, -L 1 O—, -L 1 O—CO—, -L 1 CO—O—, or -L 1 O—CO—O—; X 2 and X 5 each independently represent a linking group consisting of a direct bond, an ester bond, an ether bond, a C 1-8 alkylene group that may be branched and that may have an unsaturated bond, or a combination thereof; X 3 represents a direct bond, —CO—, -L 2 -, —OL 2 -, —O—COL 2 -, —CO—OL 2 -, or —O—CO—OL 2 -; X 4 represents a direct bond, —CO—, -L 1 -, -L 1 O—, -L 1 O—CO—, -L 1 CO—O—, or -L 1 O—CO—O—; X 6 represents a direct bond, -L 2 -, —OL 2 -, —O—COL 2 -, —CO—OL 2 -, or —O—CO-OL 2 -; L 1 and L 2 each independently represent a C 1-8 alkylene group that may be branched, wherein the C 1-8 alkylene group may be interrupted one to three times by an oxygen atom; and n and m each independently represent 0 or 1.
