Abstract
This invention provides a process for producing a heat resistant metallic laminated sheet which is composed of mutually insulated outer metallic sheets or foils and an inner binder layer sandwiched therebetween. In this process, the binder layer is a film of a heat resistant heterocyclic polymer from which volatile matter is substantially removed. The sandwiched structure composed of the outer metallic sheets and the binder film put therebetween is bonded at a temperature range above the heat distortion temperature of the binder film to form the metallic laminated sheet.
