Multilayered film, reflection-type polarizing film, and half mirror |
摘要 |
<p>There is provided a multilayer film which is useful as a refractive polarizer film or a semi-transparent film. The multilayer film comprises a first layer comprising of a polyester whose main recurring unit is ethylene-2,6-naphthalene dicarboxylate and a second layer comprising mainly of a thermoplastic resin which is different from the polyester of the first layer, wherein at least one of the first and second layers contains 0.001 to 0.5 wt% of inert fine particles having an average particle diameter of 0.01 to 2 mu m; the first and second layers each have a thickness of 0.05 to 0.3 mu m and are laminated alternately to form a laminate comprising at least 11 layers; the laminate is oriented at least in one direction; and the second layer has a lower refractive index than the first layer at least in one direction. This multilayer film has excellent handling properties such as film formability and windability and an easily adjustable reflectance.</p> |
