PURPOSE: To prevent craze at a colored mirror finished position of a transparent styrene-based film having a print layer and an aluminum vapor deposited layer on a transparent styrene sheet having a specific thickness by so laminating the film that the aluminum vapor deposited layer is disposed outside.
CONSTITUTION: A laminated film in which a transparent styrene-based film 1 having a thickness of 15-100μm and a print layer 3 and an aluminum vapor deposited layer 2 are laminated on a transparent styrene-based sheet 4 having a thickness of 0.1-1.0mm is so laminated that the layer 2 is disposed outside the film 1. A styrene-based sheet is a transparent polymer containing 70% or more of styrene and includes, for example, polystyrene, styrene-acrylonitrile copolymer, etc. As a laminating method, a thermal laminating is preferable. Thus, a color developed position formed of the print layer and the deposited layer is not crazed.
