PROBLEM TO BE SOLVED: To provide a laminate film which is hardly broken while the laminate film includes an acrylic resin film as a base and is subjected to a surface treatment, and which is suitably used as a protective film of a polarizing film.SOLUTION: A surface-treated laminate film 10 comprises a laminate film 16, in which an acrylic resin layer 12 is laminated on a polycarbonate resin layer 15, and a surface-treated layer 18 is formed on the surface of the acrylic resin layer 12. The surface-treated layer 18 gives a pencil hardness scale of H or harder to the film. The laminate film 16 has a total film thickness of 35 to 100 μm and an internal haze of 5% or less. The thickness of the polycarbonate resin layer 15 is 2 to 45% of the total film thickness of the laminate film 16. The thickness of the acrylic resin layer 12 is 30 μm or more. When the acrylic resin layer is laminated on both surfaces of the polycarbonate resin layer 15, the surface-treated layer 18 is formed on a surface of one of the acrylic resin layers to satisfy the above requirements. |
