PROBLEM TO BE SOLVED: To provide a laminated film excellent in abrasion resistance and scratch resistance.SOLUTION: In a laminated film including two transparent thermoplastic resin layers, a stiffness modulus specified by JIS-K-7106 is 260-310 MPa on an upper layer on a surface side, and 50-100 Mpa on a lower layer, and the transparent thermoplastic resin layer has an ethylene-methacrylic acid copolymer as a main chain and intermolecular crosslinking is formed by a metal cation on a side chain. Ranges of the stiffness modulus of resin of the film on the upper layer and the lower layer are specified respectively, they are used in combination, and the laminated film excellent in abrasion resistance and scratch resistance can be obtained. |
