Abstract
Abstract A photo-curable epoxy resin type composition which comprises (a) an epoxy resin, (b) a compound having at least one group represented by the formula: -NH-, (c) an organic metal compound, and (d) an organic silicon compound capable of forming a silanol group by irradiation with light. The photo-curable epoxy resin type composition according to this invention is capable of readily curing by light (ultraviolet ray in particular) and also capable of heat-curing at a temperature of 150 °C or more, and yet free from inclusion of ionic impurities from the cured product, free from corrosion of metallic materials which may be in contact with the composition, and having excellent electrical properties.
