Abstract:
A method for forming electrically insulating thin films wherein the method comprises coating the surface of a substrate with a composition comprising(A) a resin selected from the group consisting of electrically insulating, heat-curing organic resins and electrically insulating, heat-curing inorganic resins; and(B) a solvent capable of dissolving the resin (A); and(D) at least one solvent-soluble substance selected from(i) substances that upon heating at a temperature of from 0.degree. C. to 800.degree. C. generate a gas or;(ii) substances that by interaction with resin (A) generate a gas;evaporating the solvent (B); and subsequently exposing the substrate to high energy radiation and inducing the generation of gas from the substance (D) during the course of or after the cure of the resin (A).
