Title: WHITE REFLECTIVE FILM
Abstract:
The present invention addresses the problem of providing a white reflective film that is capable of sufficiently suppressing adherence to a light guide plate, that is a water-based coating layer and suppresses adherence to a light guide plate even in a hot and humid environment, and that has high formability after being recovered. In order to solve the problem, this white reflective film has a coating layer formed from a water-based coating solution having solid content that contains, as main constituent components, a binder resin and particles, wherein the coating layer has, on the surface thereof, protrusions formed by the particles, the number of protrusions having a height of 5 µm or more is 104 to1010/m2, and the binder resin contains, with respect to the mass of the binder resin, 5 to 50 mass% of a copolymerized polyester resin having a glass transition temperature Tg of 100 to 120°C, and 50 to 95 mass% of a thermoplastic resin having a glass transition temperature Tg of less than 100°C.
