    摘要: A polyimide film having improved adhesiveness is produced by flow-casting a solution of a polyamic acid, which is prepared by reacting a tetracarboxylic acid component and a diamine component, on a support, and drying the solution to form a self-supporting film; applying a solution containing a surface treatment agent to one side or both sides of the self-supporting film, wherein the solvent of the surface treatment agent solution is a water-soluble liquid and has a surface tension of 32 mN/m or less at 20° C. and a boiling point of 125° C. or higher; and heating the self-supporting film to provide a polyimide film.
