    摘要: A multilayer polyester film, and a method for making the same, is provided. The film consists of alternating layers of polyethylene terephthalate and polyethylene naphthalate. Biaxial orientation and subsequent restrained heat setting of these materials results in thin films with tensile moduli in both stretch directions well in excess of the values obtained with monolithic films of either material. In some embodiments, a slippery surface is imparted to the film without the use of conventional slip agents.

    摘要: Disclosed herein is an optical article having a top layer with a structured surface that collimates light, a core layer secured to the top layer opposite the structured surface, and a bottom layer secured to the core layer opposite the top layer. Either the top layer or the core layer includes a first extrudable polymer having a flexural modulus of greater than 2.5 GPa, and the other layer includes a second extrudable polymer having a flexural modulus of 2.5 GPa or less, an impact strength of greater than about 40 J/m, and tensile elongation at break of greater than about 5%. The bottom layer includes a third extrudable polymer. The bottom layer of the optical article may be structured to diffuse light. One or two optical articles may be secured to an optical film such as a polarizer film. Methods and display devices are also disclosed herein.
