<p>[PROBLEMS] To provide a reflective film whose reflectance drop by ultraviolet irradiation is slight, excelling in yellowing prevention. [MEANS FOR SOLVING PROBLEMS] There is provided a reflective film comprising a base layer of resin composition whose main component is an aliphatic polyester resin and, sequentially superimposed thereon, a metal thin film layer and a protective layer, wherein the base layer is arranged on the reflection application side and has internal voids whose proportion based on the base layer is 50% or below, which reflective film when irradiated with light from the base layer side, exhibits an average reflectance of 90% or higher at 420-700 nm light wavelength region. The metal thin film layer can consist of a deposited film of silver per se or alloy of silver and another metal, or can consist of a laminate of a silver deposited film and at least one layer selected from the group consisting of alloy deposited films.</p> |
