Patent ID: 7981320

Claim:
A polymerizable composition comprising a bifunctional (meth)acrylate compound represented by the following general formula (1) and a monofunctional (meth)acrylate compound represented by the general formula (2): wherein R 1 and R 2 each independently represent a hydrogen atom, a methyl group, or a halogen atom; rings A 1 , A 2 , and A 3 each independently represent a benzene ring, a cyclohexane ring, a cyclohexene ring, a naphthalene ring, a decahydronaphthalene ring, a tetrahydronaphthalene ring, or a phenanthrene ring; these rings may be substituted with an alkyl group having 1 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, a halogen atom, or a cyano group; al least one of the rings A 1 , A 2 , and A 3 comprises a substituent; —CH═ in these rings may be replaced by —N═, and —CH 2 — in these rings may be replaced by —S— or —O—: L 1 , L 2 , and L 3 each independently represent —COO—, —OCO—, —(CH 2 ) p —, —CH═CH—, —(CH 2 ) q O—, —CH═CHCH 2 O—, —C≡C—, —(CH 2 ) 2 COO—, or —CF═CF—; n represents an integer from 0 to 3; and, when n is 2 or larger, L 3 and A 3 may be the same or different; p and q each independently represent an integer from 1 to 8: wherein R 1 represents a hydrogen atom, a methyl group, or a halogen atom; rings A 4 and A 5 each independently represent a benzene ring, a cyclohexane ring, a cyclohexene ring, a naphthalene ring, a decahydronaphthalene ring, a tetrahydronaphthalene ring, or an anthracene ring; these rings may be substituted with an alkyl group having 1 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, a halogen atom, or a cyano group; —CH═ in these rings may be replaced by —N═, and —CH 2 — in these rings may be replaced by —S— or —O—; L 4 and L 5 each independently represent a single bond, —COO—, —(CH 2 ) p —, —CH═CH—, —(CH 2 ) q O—, —CH═CHCH 2 O—, —C≡C—, —(CH 2 ) 2 COO—, or —CF═CF—; p and q each independently represent an integer from 1 to 8.
