<p>A polyphenylene sulfide resin film is provided which is excellent not only in heat resistance, chemical resistance, and adhesion to a substrate material but in releasability from the substrate material after a treatment. Also provided is a laminate. A polyphenylene sulfide resin composition containing 0.1-30 vol.% syndiotactic polystyrene is biaxially stretched to form a polyphenylene sulfide resin release film having a thickness of 20-100 µm. The film is used as a release film in, e.g., the step of producing a rigid substrate.</p> |
