Abstract
PURPOSE: To produce a film excellent in the dimensional stability and having no pinhole, by casting a resin solution onto a solvent-resistant thermoplastic film having a heat resistance of over 100°C, and predrying it to have a remaining solvent amount of 15W40wt% followed by peeling thereof.
CONSTITUTION: The resin solution comprising as main constituents one or more of resins selected from a group consisting of polyimide precursors, polyamide precursors, polyimide polymers and polyamide-imide polymers is cast onto a support comprising a solvent-resistant thermoplastic resin film having a heat resistance of over 100°C, is predried to have a remaining solvent amount of 15W40wt%, is peeled off from the support, and is further dried to produce the polyimide film or poly-amide- imide film. Accordingly, as the formed film is easily released from the support, a film excellent in the dimensional stability and having no pinhole can be produced.
