Abstract:
A photosensitive resin composition comprising:(a) a polymer having repetition units expressed by a general formula (1): wherein,R1, R3, and R5 each represents a hydrogen atom or a methyl group, R2 represents a non-aromatic bridged cyclic hydrocarbon group having a carbon number in the range of 7 to 22 inclusive, R4 represents a non-aromatic hydrocarbon group including an epoxy group, x+y+z=1, wherein 0the polymer has a weight averaged molecular weight of 1,000 to 500,000; (b) a photo acid generator, the weight ratio between (a) and (b) being 75 to 99.8 weight parts of (a) to 0.2 to 25 weight of (b), and (c) a multi-functional epoxy compound present in an amount of 0.5 to 60 weight parts per 100 weight parts of (a) plus (b) plus (c).
