MANUFACTURE OF LAMINATE CONSISTING OF AT LEAST ONE KIND OF LAYER COMPOSED OF METAL AND AT LEAST ONE KIND OF LAYER MADE UP OF POLYIMIDE DIRECTLY COUPLED WITH SAID LAYER

摘要

1. Process for producing laminates from at least one layer consisting of a metal M 1 and at least one polyimide layer, directly bonded thereto, by applying a layer of a solution of a polyimide or of a solution of a polyamide-acid, convertible to a polyimide, to a carrier and converting the solution to solid polyimide, characterized in that a carrier is used which consists of a layer of a metal M 1 and a layer, bonded thereto, of a material M 2 different from M 1, the material M 2 having at least one smooth surface on which the layer of metal M 1 is located, which layer has been produced by vapour deposition, printing, knife application or spraying of the metal M 1 in the elemental form on this surface, that the solution of the polyimide or of the polyamide-acid is applied to the exposed surface of the layer of metal M 1, and that, after the conversion of the solution to solid polyimide, the layer of material M 2 is removed.
