Abstract

PURPOSE: The titled composition especially suitable for a resin impregnated condenser, having increased dielectric constant, obtained by blending an epoxy resin with an organic compound with high dielectric constant and a curing agent of an acid anhydride.
CONSTITUTION: An epoxy resin (preferably disphenol type) is blended with a curing agnet of an acid anhydride group-containing acid anhydride (anhydrous hexahydrophthalic acid, etc. is effective) in an amount corresponding a ratio of epoxy equivalent 0.7W1.2, preferably 0.8W1.0, and 10W120wt%, preferably 30W 100wt% one or more organic compounds having high dielectric strength selected from the group consisting of glycerol, 3-chloro-1,2-propanediol, 2-undecanone, salicylaldehyde, 0-dichlorobenzene, and 1,4-butandediol. The dielectric constant of the cured resin increases by 10W40%, the dielectric strength in the use of the resin composition as an impregnating resin for a condenser improves by 10W30%, and the size of the condenser can be miniaturized by 10W30%.
