ABSTRACT:
The invention relates to laminates comprising at least one layer of an intractable, fully aromatic polyimide which, on one side, is directly bonded to a layer of a substrate and, on the other side, to a layer of a heat-sealable polyimide. The basic elements thus produced may be bonded to one another on the heat-sealable polyimide sides or one basic element may be bonded to another layer of substrate. Further layers may be bonded to one or both outside(s) of the laminates. The laminates may be produced by a novel temperature-controlled process. The substrates are preferably foils of metals or alloys. The multilayer laminates obtained are distinguished by outstanding mechanical, thermal and electrical properties. They may be used as reinforcing materials or for printed electrical circuits.
