PROBLEM TO BE SOLVED: To provide a laminated film for molding simultaneous transfer which is excellent in the moldability, dimensional stability, processing suitability and the appearance after the molding.SOLUTION: In the laminated film formed by laminating a release layer at least on one side of a base material film whose principal ingredient is a polyester resin, both of the stresses in the longitudinal and width directions at the 100% stretching at 190°C is 5-50 MPa, and both of the dimensional change ratios in the longitudinal and width directions when increasing the temperature from 25 to 100°C at the rate of 5°C/min while applying the load of 5 MPa to the film are 1-5%, and the surface free energy of the release layer is 36-42 mN/m, and the film glossiness is 140-200. |
