PURPOSE:To produce the titled compsn. which hardly causes precipitation of fillers and has excellent long-term shelf stability, by adding a filter to an epoxy blend contg. a crystalline epoxy resin and/or a crystalline hardener, heating the mixture at a specified temp. and gradually cooling it. CONSTITUTION:A filler is added to an epoxy blend contg. at least one member selected from among crystalline epoxy resins (e.g., triglycidyl isocyanurate) and crystalline hardeners (e.g., tetrahydrophthalic anhydride). The mixture is mixed at a temp. not higher than a temp. of higher by 10 deg.C than the m.p. of the epoxy resin or the hardener for 30min or shorter and then gradually cooled at a rate of 50 deg.C/hr or below.
