Abstract

PURPOSE: To prepare the titled composition having improved electrical insulation resistance, heat resistance, and punchability, without lowering the flame-retardancy, by compounding a specific epoxy resin to a phenolic resin containing a flame- retardant.
CONSTITUTION: 100pts.wt. of a phenolic resin is mixed with pref. 5W35pts.wt. of a frame-retardant (e.g. a phosphoric acid ester) and an epoxy resin of formula. For example, prepreg sheets prepared by the impregnation and drying of the composition in craft paper sheets, are laminated and pressed between a pair of molding metal plates to obtain a laminated board.
