PROBLEM TO BE SOLVED: To provide a laminate film having effective scratch resistance even under conditions of rubbing with a material having high hardness under a heavy load or repeated rubbing with a material having low hardness.SOLUTION: The laminate film includes a surface layer 1 comprising at least one layer formed on a support substrate 2. In a cross section of the surface layer 1 perpendicular to the support substrate 2, elastic modulus E, E, E, Emeasured by an atomic force microscope, at positions corresponding to 5% (position A 3), 35% (position B 4), 65% (position C 5), and 95% (position D 6) of thickness of the surface layer, from the surface of the surface layer 1, respectively, satisfy all of the following conditions: (condition 1) E≤E≤E<E; (condition 2) Eis equal to or less than 100 MPa; and (condition 3) Eis equal to or more than 1 GPa.SELECTED DRAWING: Figure 1 |
