A front scattering film capable of reducing backward scattering and providing a clear display is provided. The front scattering film comprises a light scattering layer composed of a transparent polymer binder and spherical microparticles dispersed in the binder and having a refractive index different from that of the binder, and substrates provided on the both sides of the light scattering layer, wherein at least one of the substrates is peelable from the light scattering layer. This front scattering film does not impair the function of the liquid crystal display unit by, for instance, affecting polarization, even it is used in a liquid crystal display unit in which a light scattering layer provided by the front scattering film is arranged between a retardation film or polarizer film and a liquid crystal layer.

Front scattering film with a light scattering layer and a peelable substrate

Disclosed is a front scattering film which comprises a light scattering layer consisting of transparent polymer binder containing spherical microparticles , a transparent resin film and an adhesive layer , wherein the spherical microparticles have a mean particle diameter of 1.0 &mgr;m to 10.0 &mgr;m, and a refractive index (n) relative to refractive index of the transparent polymer binder satisfying a condition of 0.91<n<1.09, and the front scattering film has a haze of 30.0% or more and a distinctness of image of 60.0% or more. The front scattering film according to the present invention can exhibit excellent display characteristics including performance of exhibiting paper-like white in white state and black in black state, high contrast of image display, no blurring and the like, and realize extremely easy production control thereof.

A view angle control sheet comprising a non-oriented light permeable polymer layer having cracks of regular directionality is disclosed. The view angle control sheet of the present invention has good view angle control property and can easily be obtained at low cost. The sheet having good view angle control property with respect to two or more directions can also easily be obtained as required at low cost. The view angle control sheet of the present invention can be used in office equipment displays, automobile meters, outdoor displays, windows and the like to desirably control view angles.

View angle control sheet and method for producing the same

A reflection screen includes a light-reflecting substrate laminated with a light-transmitting polymer layer having light absorptive crazes of regular directionality. The reflection screen is formed by coating or laminating the light-reflecting layer on the substrate, drawing over a blade in a direction perpendicular to the blade to form the crazes and inserting a light-absorbing material into the crazes. Images projected on the reflection screen have high contrast and can be observed as sharp images even in a lighted area such as in a room lighted by fluorescent lighting.

Reflection screen and method for producing the same

The present invention is directed to a printing plate using an indirect electrophotographic process. The printing plate comprising an image receiving layer provided on a surface of plastic film wherein the image receiving layer comprises two types of extender pigments having different average particle size range to impart unevenness to the surface of the image receiving layer. The printing plate is suitable for use as a printing plate for lithography.
