PURPOSE:The titled solventless composition having a low viscosity, a long pot life and high heat resistance, containing a polymaleimide, an alkenylphenol (ether) and a polycarboxylic acid allyl ester. CONSTITUTION:A thermosetting resin composition containing a polymaleimide (e.g., N,N'-ethylenedimaleimide), an alkenylphenol and/or its ether (e.g., a reaction product between o-allylphenol and an aldehyde), and a polycarboxylic acid allyl ester (e.g., diallyl terephthalate). This is a thermosetting resin composition having heat resistance class C (>=180 deg.C), and particularly used as a solventless varnish for impregnation, casting, lamination, molding, bonding, etc.
