PURPOSE: The titled composition, capable of being easily impregnated and cast, having improved heat resistance and mechanical properties, and comprising an epoxy resin containing an imide ring, an acid anhydride and a polyfunctional maleimide compound.
CONSTITUTION: A composition comprising (A) an epoxy resin containing an imide ring obtained by reacting (a) an imidodicarboxylic acid having at least one imide ring in the molecule, e.g. formula I (R1 is bifunctional organic group) with (b) a polyfunctional epoxy compound, e.g. bisphenol A epoxy resin, (B) an acid anhydride as an epoxy resin curing agent and (C) a polyfunctional maleimide compound, e.g. formula II (R2 is H or CH3). The amount of the component (C) is 80W5pts.wt. per 20W95pts.wt. the mixture of the components (A) with (B). 0.5W20pts.wt. a phenoxy resin is further incorporated with 100pts.wt. the composition if necessary.
