PURPOSE:To improve moldability, heat resistance, surface gloss after processing and writing properties, by limiting gloss of a film and film strength at the time of extension. CONSTITUTION:Gloss Gs (60 deg.) of a film is made 10-90%. Since the film whose Gs (60 deg.) is less than 10% is inferior in surface gloss properties, it is not preferable since the surface of a molded product after molding processing becomes roughened too much. On the one hand, it is not preferable since sufficient matting is not given to the surface of molded product in the film exceeding 90%. It is preferably 20-90%. Film strength F110 at the time of extension of 100% under an atmosphere at 150 deg.C is made 0.5-7 kg/mm<2>. The F110 is a mean value of longitudinal and lateral strength of the film at the time of the extension of 100% at 150 deg.C. It is preferably 0.5-5 kg/mm<2>, preferably further a range of 0.5-4kg/mm<2>. |
