Abstract
A paint substitute film comprises a base film, a colored layer, and a hard coat layer, wherein the base film, the colored layer, and the hard coat layer are laminated in this order. The base film contains thermoplastic resin and concealing material. Refractive index of the concealing material is not less than 1.70. Scattering coefficient from wavelength 400 nm to 700 nm of the base film is not less than 0.20 μm−1. Contrast ratio of the base film when at 20% elongation is not less than 0.70.
