Flexible multilayer polyimide metal-clad laminates, and their preparation, having at least one layer of aromatic polyimide bonded to at least one layer of a metallic substrate using a heat-sealable copolyimide adhesive containing repeating imide units derived from 4,4'-oxydiphthalic dianhydride and an aromatic ether diamine. The laminates are used in flexible printed circuits and tape automated bonding applications. Additionally, the metallic substrate may be directly coated with the copolyimide adhesive and used as a single-clad laminate for flexible printed circuits.

A reactive oligoimide, which may serve as an adhesive for bonding at least one layer or film to another layer, preferably a flexible metallic layer to a flexible layer of a polyimide, in order to form a flexible multilayer metal-clad laminate.
A multilayer laminate having a metallic layer and a dielectric layer, such as a chemically etchable polyimide, bonded to each other with a chemically etchable adhesive containing phenolic ester groups in the backbone.
A reactive oligoimide which is chemically etchable upon crosslinking, and which may serve as an adhesive for bonding at least onelayer or film to another layer, preferably a flexible metallic layer to a flexible layer of an etchable polyimide, in order to form a flexible multilayer metal-clad laminate.
