Abstract
PURPOSE: To prolong a pot life of epoxy resin and to improve workability, by modifying the epoxy resin with an aryl ester.
CONSTITUTION: An epoxy compound having one or more epoxy groups with high reactivity is modified by an aryl ester in an amount to give 0.3W3, preferably 0.5W 2, aryl ester groups per epoxy groups. When the epoxy compound is an epoxy resin having two or more epoxy groups, the epoxy resin is modified by a polyaryl ester, e.g., triacetyl phloroglucinol, or diphenyl phthalate, in an amount to give 0.1W1.2, preferably 0.3W0.7, aryloxycarbonyl group per epoxy group.
