ABSTRACT:
A method for preparing a high-heat-resistant-epoxy-resin composition which comprises adding, as catalytic curing agent, a quinoxalinium salt having a benzyl group to difunctional and multifunctional epoxy resin and thermoset resin having a similar structure. The epoxy-resin composition obtained by the present invention is excellent in its impregnating property, processability, impact resistance, drug resistance, electric-insulating property, and adhesiveness.
