Abstract

PURPOSE: An epoxy resin composition moldable by dry lamination, having improved heat and water resistance, and storage stability, comprising a specific epoxy resin, a cuving agent, a cuving accelerator, etc.
CONSTITUTION: An epoxy resin comprising (A) a novolak epoxy resin, e.g. phenol or o-cresol novolak epoxy resin, (B) a bisphenol A diglycidyl ether, preferably an epoxy equivalent of 350W1,200, (C) dicyandiamine, and (D) a urea derivative of the formula (X1 and X2 are OCH3, NO2, Cl, or H) as a curing accelerator as essential ingredients.
