ABSTRACT:
A photopolymerizable epoxy resin composition comprising (a) an epoxy resin and (b) a heteropoly-acid aromatic sulfonium salt or a heteropoly-acid aromatic iodonium salt as a photocuring catalyst exhibits rapid photopolymerization, with the cured product being great in hardness, the corrosive action being weak, and the electrical properties being excellent. The industrial utility of the composition is therefore substantial.
