[Problem] To provide an optical reflection film having a refractive index layer that includes a water-soluble resin, wherein there is little coating failure and little cracking even after a long period of use. [Solution] An optical reflection film that is provided with a substrate and a dielectric multilayer film disposed on one surface of the substrate and formed by alternately layering low refractive index layers and high refractive index layers. At least one of the low refractive index layers and high refractive index layers is a water-dispersible hydrophobic resin–containing layer that includes a water-soluble resin and 5–55 mass%, relative to the total mass of the layer, of a water-dispersible hydrophobic resin. |
