POLYIMIDE FILM, POLYIMIDE LAMINATE COMPRISING SAME, AND POLYIMIDE/METAL LAMINATE COMPRISING SAME

摘要

The adhesion between the adhesive and the adhesive and / or a metal layer of improved polyimide imide film is disclosed. The polyimide film, has at least a polyimide layer (b) and said polyimide layer (b) polyimide layer (a) formed in contact with the polyimide layer (a) is a tetracarboxylic acid dianhydride component and the general a polyimide formed as the diamine component comprising a diamine compound represented by the formula (1). (Wherein represents one, R ¹ is a hydrogen atom, a group having 1 to 12 carbon atoms in the alkyl group or aryl, R ² is an alkyl group having 1 to 12 carbon atoms or aryl group)
