Abstract:
A thermoplastic film 10 is a thermoplastic film comprising a light-emitting layer 11, wherein the light-emitting layer 11 comprises a thermoplastic resin and a light-emitting material that emits light by being irradiated with excitation light, and when laminated glass obtained by bonding two sheets of clear glass in accordance with JIS R 3211(1998) having a thickness of 2.5 mm with the thermoplastic film interposed therebetween is irradiated, from one surface, with excitation light, which the light-emitting material is capable of absorbing, in a quantity of light of 7 mW/cm2, a difference between luminance A observed on a side of the one surface and luminance B observed on a side of the other surface, (A−B), is 5 cd/m2 or more. According to the present invention, a thermoplastic film such that when laminated glass is made using the thermoplastic film, information is displayed relatively strongly on one surface, and the information is displayed relatively weakly on the other surface, and a laminated glass comprising this thermoplastic film can be provided.
