Abstract
The cyclohexanetricarboxylic monoester of the present invention is represented by the following formula 1: wherein R is as defined in the specification. The cyclohexanetricarboxylic monoester is useful particularly as the curing agent for epoxy-containing compounds. A heat-curable resin composition comprising the cyclohexanetricarboxylic monoester and an epoxy-containing compound exhibits an excellent curability without using a curing accelerator and provides a colorless transparent cured product which is little discolored even under a long-term exposure to high-temperature conditions. Such a heat-curable resin composition is suitable as sealing materials for photoelectric transducers such as blue LED and white LED, shaped articles, coating materials, adhesives, etc.
