PURPOSE:To obtain the mirror surface of a film in a simple combination process by a method in which after an auxiliary film has been laminated on the thermoplastic resin film on which a mirror surface-treatment is to be applied at the working temperature of at least softening point and at most melting point of said resin, the thermoplastic resin film is separated from the auxiliary sheet and is removed. CONSTITUTION:On are surface of the soft polyvinylchloride film composed of the color clear calender sheet with 54 part content of plasticizer, the auxiliary sheet composed of polyethyleneterephthalate film is laminated at 100 deg.C-180 deg.C by using the roll for calender coat, and then after it has been cooled to room temperature, the polyethyleneterephthalate film, as the auxiliary film, is separated from the surface of a soft polyvinylchloride film and is removed, whereby easy adhesion to the smooth surface of e.g. glass formed body, etc. is shown. That is, the thermoplastic resin film providing an excellent mirror surface is obtained in a simple combination process. |
