Abstract

PURPOSE: A composition for an electrical insulating material, stable at normal temperature and quickly curable by heating, obtained by blending an epoxy resin with an amine, carboxylic acid anhydride as a curing agent and a specific cephalosporin compound as a potential curing accelerator.
CONSTITUTION: (A) An epoxy resin, e.g., diglycidyl ether of bisphenol A, is blended with (B) one or more curing agents selected from the group consisting of an amine compound (e.g., 4,4'-diaminodiphenylmethane, etc.), a carboxylic acid anhydride compound (e.g., tetrahydrophthalic anhydride, etc.), phenol-formaldehyde novolak compound, and (C) a curing accelerator consisting of a cephalosporin compound (e.g., diacetylcephalosporin C, etc.) shown by the formula (X is OH or OCOCH3). Preferably an amount of the ingredient B is 0.01W5wt% based on ingredient A, and an equivalent ratio of C to A is 1:0.8W1.5, to give the desired compound.
