Claim:
A polymerizable composition containing at least one compound represented by the following formula (A): wherein P 1 and P 2 each represents a polymerizable group selected from the groups represented by the following formulae (P-1) to (P-5): wherein R 11 to R 13 each represents a hydrogen atom or a methyl group; m1 and m2 each indicates an integer of from 2 to 8, and of m1 or m2 CH 2 's, one CH 2 or two or more CH 2 's not adjacent to each other may be replaced by an oxygen atom or a sulfur atom; n1 is 0, 1 or 2; n2 is 1 or 2; A 1 , A 2 , A 3 and A 4 each represents a substituted or unsubstituted, 5- to 18-membered aromatic hydrocarbon ring or 5- to 18-membered aromatic hetero ring residue; R represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, however, when n1 is 1 or 2, R may be an alkyl group having from 5 to 8 carbon atoms; Z 1 and Z 2 each represents —COO—, —OCO—, —NHCO— or —NR 1 CO—, and R 1 represents an alkyl group having from 1 to 10 carbon atoms, however, when n1 is 0, Z 2 may be —OCO—CH═CH—; L 1 and L 2 each represents —O—, —S—, —COO—, —OCO—, —OCOO—, —NHCO— or —NR 1 CO, and R 1 represents an alkyl group having from 1 to 10 carbon atoms, however, when n1 is 0, L 1 and L 2 each may be —OCO—CH═CH—.
