<p>The present invention provides a protective film which can be adhered to a substrate having a three-dimensional characteristic. This can be achieved even when the operation is conducted in-situ at temperatures of 40° C. to 60° C. The decorative protective film comprises a toughening layer, a protective (preferably embossable) layer, and an adhesive layer. The protective layer is on one side of the toughening layer. The adhesive layer is on the other side of the toughening layer. The protective layer comprises a thermoplastic amorphous polyester resin having a tensile modulus of 400 to 2100 MPa. The toughening layer comprises a polyurethane resin having a glass transition temperature of -50°C. to 0°C. The toughening layer may be colored.</p> |
