1. A photosensitive resin composition comprising(A) a carboxyl group-containing photosensitive resin, (B) an epoxy curing agent represented by the following formula (I):
-
wherein R1, R2, R3 and R4 are independently a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 10 carbon atoms, provided that at least one of R1, R2, R3 and R4 is an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 18 carbon atoms;
R5 and R6 are independently a hydrogen atom or an alkyl group having 1 to 2 carbon atoms; and
n is 0, 1, 2 or 3, and(C) a photopolymerization initiator.
