Light-reflecting film and light reflector using the same

Abstract

To provide a light-reflecting film that, while ensuring tight adhesiveness to an adherend having a curved surface, leaves little adhesive residue when peeled from an adherend for the purposes of re-attaching, can be re-attached, and is excellent in durability and heat ray-shielding conductance. A light-reflecting film including: a reflective layer having at least one or more laminate(s) in which a high refractive index layer containing a polymer and a low refractive index layer containing a polymer are laminated; a pressure-sensitive adhesive layer that is disposed on one outermost layer; and a hard coat layer that is disposed on another outermost layer, wherein the elastic modulus of the pressure-sensitive adhesive layer and the elastic modulus of the hard coat layer satisfy the following Formula (1): the elastic modulus of the hard coat layer [Pa]/the elastic modulus of the pressure-sensitive adhesive layer [Pa]≧3, and the instantaneous pressure-sensitive adhesive force exhibited when the pressure-sensitive adhesive layer is applied to glass is from 2 to 8 N/25 mm.
