Abstract

PURPOSE: A thermosetting resin composition that is made by mixing a specific novolak type condensate, an isocyanate-modified epoxy resin and a curing catalyst in a specific proportion, thus being used as an electrically insulating material because of its high heat resistance, mechanical strength, and good workability.
CONSTITUTION: The objective composition is produced by mixing (A) a novolak type condensate obtained by the reaction between (a) a diphenyl ether derivative of formula I (Y is hydroxyl, 1W4C alkoxy) and (b) a phenolic derivative of formula II (R is alkyl, aralkyl, aryl) in the presence of an acidic catalyst, (B) an isocyanate-modified epoxy resin obtained by the reaction between (c) an isocyanate and (d) an epoxy resin at an equivalent ratio of 1/1.5W5 in the presence of a catalyst for forming heterocyclic ring and (C) a curing catalyst, where the weight ratio of A:B:C is preferably 30W55:70W45:0.2W2.
USE: Laminate, coating and others.
