PURPOSE:The titled composition providing a cured material having improved heat-resistant cycle characteristics, obtained by blending a resin composition comprising an epoxy resin and a curing agent with an organic phosphine compound, antimony tetroxide, etc., in a specific ratio. CONSTITUTION:(A) 90-30pts.wt. epoxy resin (novolak type epoxy resin having preferably 170-300 epoxy equivalent) is blended with (B) 10-70pts.wt. curing agent containing >=2 phenolic hydroxyl groups (preferably novolak type phenolic resin, etc.), (C) 0.01-20pts.wt. organic phosphine compound (preferably aryl phosphine compound), (D) 0.1-30pts.wt. one or more of diantimony tetroxide, Sb6O13, and diantimony pentoxide, and, if necessary, (E) a halogen compound (e.g., brominated epoxy resin, etc.), (F) an inorganic filler (e.g., molten silica, etc.), to give the aimed composition. |
