Abstract

PURPOSE: A low-viscosity, long-pot life electrical insulating epoxy resin composition capable of providing cured products with improved heat resistance, comprising a specified epoxy compound and a polycarboxylic acid anhydride.
CONSTITUTION: An epoxy resin composition comprising a polycarboxylic acid anhydride and, as an epoxy resin, an expoxy compound represented by formula I, wherein R1 and R2 are each H or methyl and n is 0 or 1. As the epoxy compounds of formula I, there can be mentioned diglycidyl 4,5-epoxycyclohexane-1,2-dicarboxylate or diglycidyl 3-methyl-4,5-epoxycyclohexane-1,2-dicarboxylate. The epoxy compounds of formula I can be prepared, for example, by epoxidizing an unsaturated cyclic dicarboxylic acid diallyl ester of formula II with an organic peracid.
