<P>PROBLEM TO BE SOLVED: To provide an epoxy-based resin composition not only capable of reducing the amount of produced fluoride ions and improving resistance to electrolytic corrosion during thermal cationic polymerization but also having excellent low-temperature quick curability. <P>SOLUTION: The epoxy-based resin composition comprises an epoxy resin and a thermal cationic polymerization initiator. In the resin composition, a sulfonium borate complex represented by formula (1) (wherein, R<SB>1</SB>is an aralkyl group; R<SB>2</SB>is a lower alkyl group, with the proviso that R<SB>1</SB>is not a benzyl group when R<SB>2</SB>is a methyl group; X is a halogen atom; and n is an integer of 1-3) is used as the thermal cationic polymerization initiator. <P>COPYRIGHT: (C)2009,JPO&INPIT |
