Abstract:
1. A photocurable resin composition comprising: (A) 100 parts by weight of an epoxy group-containing polymer compound having repeating units represented by the following general formula (1) and having a weight average molecular weight of 3,000 to 500,000, where R 1 to R 4 , which may be identical or different, are each a monovalent hydrocarbon group of 1 to 8 carbon atoms, m is an integer of 1 to 100, a, b, c and d each indicate the proportion of each of the repeating units based on the total number of the repeating units, and are each 0 or a positive number, such that c and d are not simultaneously 0 and that 0 <(c+d)/(a+b+c+d)≦1.0, and X and Y are each a divalent organic group represented by the following general formula (2) or (3), provided that the polymer compound has at least one divalent organic group represented by the formula (3), where Z is a divalent organic group selected from among n is 0 or 1, R 5 and R 6 , which may be identical or different, are each an alkyl or alkoxy group of 1 to 4 carbon atoms, and k is any of 0, 1 and 2, where V is a divalent organic group selected from among p is 0 or 1, R 7 and R 8 , which may be identical or different, are each an alkyl or alkoxy group of 1 to 4 carbon atoms, and h is any of 0, 1 and 2; (B) 0.05 to 20 parts by weight, based on 100 parts by weight of component (A), of a photoacid generator represented by the following formula (8),  and (C) a solvent.
