ABSTRACT:
A novel thermosetting resin composition consisting essentially of (a) an isocyanate group-terminated condensate obtained by reacting a polycarboxylic acid compound having at least one acid anhydride ring with a stoichiometrical excess of a polyfunctional isocyanate compound or said condensate containing the unreacted isocyanate compound, (b) a polyfunctional epoxy compound and (c) a catalyst which forms mainly isocyanurate rings and oxazolidone rings. A cured product having excellent thermal resistance and excellent high temperature strength can be obtained by heating said composition.
