An optical reflective film including refractive index layers containing a water-soluble resin is provided, wherein the film has a small color tone variation and less occurrence of cracks even after a prolonged use. An optical reflective film, including: a substrate; and a dielectric multilayer film formed by alternately laminating a low refractive index layer and a high refractive index layer, disposed on one surface of the substrate, wherein at least one layer of the low refractive index layer and the high refractive index layer is a water-dispersible cationic urethane resin-containing layer, containing: a water-soluble resin; a refractive index adjusting agent; a water-dispersible cationic urethane resin; and a cationic polymer having a tertiary amino group or a cation (salt) thereof or a quaternary ammonium group.

Optical reflective film

Provided is means that enables a hard coat layer to resist cracking and to have improved scratch resistance in a laminated film including a substrate, a surfactant-containing layer on one surface of the substrate, and the hard coat layer on the other surface of the substrate. The laminated film includes a substrate, a surfactant-containing layer that is disposed on one surface of the substrate and contains a surfactant, and a hard coat layer disposed on the other surface of the substrate, wherein the hard coat layer contains 0.001 to 3% by weight of a (meth)acrylic modified silicone compound.
