REFLECTIVE FILM

摘要

Disclosed is a reflective film which can be used as a reflective panel for use in a liquid crystal display or the like, has a high reflection properties and shows little dimensional change under a heated environment. The reflective film comprises a layer A and a layer B laminated on one another, wherein the layer A comprises an aliphatic polyester resin and a microparticulate filler and has a percentage of void (a) of 5% or higher, and the layer B has a storage elastic modulus at 70°C (E'(70)) and a storage elastic modulus at 90°C (E'(90)) satisfying the following equation (I): Equation (I) ··· 0.5 = E'(90)/E'(70) < 1.0 The layer B does not cause rapid change in storage elastic modulus (E') at least within the temperature range from 70 to 90°C, since the layer B has physical properties satisfying the equation (I). Therefore, it becomes possible to reduce the dimensional change at a standard temperature for heat resistance evaluation (80°C).
