Abstract:
1. An epoxy resin composition comprising a compound (a) having an imide structure represented by the Formula (1), and a compound (b) having at least two epoxy groups, wherein the compound (a) having an imide structure represented by the Formula (1) has a number average molecular weight of 1,000 to 5,000: wherein R 1 has a structure represented by the Formula (2) in an amount of not less than 50%; R 2 is selected from the Formulae (4) below wherein different R 2 s are optionally employed in combination; the benzene ring in any structures selected from the Formulae (4) below is optionally substituted by one or more groups selected from the group consisting of hydroxyl group, C 1 -C 4 alkyl groups, C 1 -C 4 fluoroalkyl groups, C 1 -C 4 alkoxyl groups, C 1 -C 4 fluoroalkoxyl groups, C 2 -C 5 ester groups, carboxyl group, cyano group and nitro group; v is an integer of 1 to 8; and G is selected from the Formulae (5) below wherein different Gs are optionally employed in combination; wherein R 4 and R 5 are each independently selected from the group consisting of C 1 -C 4 alkyl groups, C 1 -C 4 fluoroalkyl groups, C 1 -C 4 alkoxyl groups, C 1 -C 4 fluoroalkoxyl groups, C 2 -C 5 ester groups, carboxyl group, cyano group and nitro group wherein these groups are optionally employed individually or different groups are optionally employed in combination as each of R 4 and R 5 ; X is selected from the group consisting of direct bond, —CH 2 —, —C(CH 3 ) 2 —, —C(CF 3 ) 2 —, —C(C 2 F 5 ) 2 —, —O—, —SO 2 —, fluorene, —CO—, —COO—, —CONH—, —CF 2 — and the Formulae (3) below wherein different Xs are optionally employed in combination; p and q are integers of 0 to 3, s and t are integers of 0 to 4, and s+t>0; and w is an integer of 0 to 8;
