Patent ID: 10012901

Abstract:
The purpose of the present invention is to provide the following: a photosensitive epoxy resin composition that, via photolithography, can form a high-resolution, low-stress image that has vertical side walls and resists moisture and heat, and/or a resist laminate using said photosensitive epoxy resin composition; and an article or articles obtained by curing said photosensitive epoxy resin composition and/or resist laminate. The present invention is a photosensitive resin composition containing the following: an epoxy resin (A), a polyol compound (B) having a specific structure, a cationic-polymerization photoinitiator (C), a silane compound (D) containing an epoxy group, and a reactive epoxy monomer (E) having a specific structure. The epoxy resin (A) contains the phenol derivative represented by formula (1), an epoxy resin (a) obtained via a reaction with epihalohydrin, and an epoxy resin (b) that can be represented by formula (2).
