Abstract:
1. A resin composition for an optical material, comprising: (A) a base polymer; (B) a photopolymerizable compound; and (C) a photopolymerization initiator wherein the component (B) contains a photopolymerizable compound which is selected from the group consisting of epoxy(meth)acrylate, acryl(meth)acrylate, fluorene di(meth)acrylate represented by the following general formula (I), (meth)acrylate represented by the following general formula (III) and a compound having 2 or more epoxy groups in a molecule thereof: wherein X is represented by the following formula (II): y is hydrogen or a methyl group; and m and n are each an integer of 1 to 20: wherein R1 to R16 independently represent hydrogen, an alkyl group having 1 to 12 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, an alkoxycarbonyl group having 2 to 7 total carbon atoms, an aryl group having 6 to 10 carbon atoms, or an aralkyl group having 7 to 9 carbon atoms; wherein R 17 is —CH 2 CH(OH)CH 2 —, —(C 2 H 4 O) h C 2 H 4 —, —(C 3 H 6 O) i C 3 H 6 —, or —(C 2 H 4 O) j —(C 3 H 6 O) k C 3 H 6 —; U is —C(CH 3 ) 2 —, —CH 2 —, —SO 2 —, or —O—; V is hydrogen or halogen; and W is hydrogen or —CH 3 , provided that h, i, j, and k are each an integer of 0 to 10.
