ABSTRACT:
The heat-curable resin composition of the present invention comprises an epoxy-containing resin and a curing agent, wherein the curing agent is cyclohexanetricarboxylic acid and/or an anhydride thereof. The heat-curable resin composition exhibits an excellent curability without using an curing accelerator and provides a colorless transparent cured product which is little discolored under high-temperature conditions and irradiation conditions of high-energy light. The heat-curable resin composition is suitable for producing coating compositions, adhesives, shaped articles, protective films for color filters and sealing materials for photosemiconductors such as blue LED and white LED.
