摘要：
A polyimide film is described having improved adhesion prepared by coating the surface of a partially cured or partially dried polyamide acid film with an organic solvent solution of a metal salt and heating the coated film to both convert the polyamide acid to polyimide and dry the film. By proper selection of the metal salt either a one-side adherable or two-side adherable polyimide film can be obtained. The polyimide film can be used in electrical insulating and flexible printed circuit applications where superior adhesion is an important requirement.
