ABSTRACT:
A polyimide film made of a multicomponent polyimide comprising two or more different polyimide components including (A) a polyimide component A being raw materials of a polyimide A and/or a polyimidation product of the raw materials and (B) a polyimide component B being raw materials of a polyimide B and/or a polyimidation product of the raw materials. The polyimide components A and B are different, for example, such that the absolute difference between solubility parameter SPAof the polyimide A and solubility parameter SPBof the polyimide B, |SPB-SPA|, is 0.5 MPa1/2or more. The polyimide film has markedly modified surface properties as compared with a polyimide film in which all the same raw materials as used in the film of the invention are randomly bonded to one another.
