Abstract: A light diffusing film for a back light display is described. The light diffusing film includes a unitary film consisting essentially of polycarbonate and a uniformly dispersed anti-static material in an amount sufficient to impart anti-static properties to the film. The anti-static material may comprise a fluorinated phosphonium sulfonate. The film may additionally include at least one textured surface for the low scattering of light. Alternatively, the film may additionally include a uniformly dispersed acrylic bulk scattering additive of particles having a mean particle size of from about 3 to about 10 microns and present in an amount from about 2 to about 7 percent by weight percent for the high scattering of light.

Abstract: Disclosed herein are backlit devices comprising multiwall sheets (120,220). In one embodiment, a backlit device comprises: a multiwall sheet (120,220) and a light source (106). The multiwall sheet (120,220), that has a viewing side (114), comprises polymer walls and a rib that intersects at least two of the walls. The rib comprises a non-linear geometry. The light source (106) is located on a side of the multiwall sheet (120,220) opposite the viewing side (114), wherein the light source (106) is configured to direct light (104) at the multiwall sheet (120,220).

Abstract: There is provided an optical diffuser sheet. The optical diffuser sheet has a first surface and a second surface opposite to the first surface. The first surface has a plurality of optical structures arranged to diffuse and direct light illuminated onto the first surface. The optical diffuser sheet when illuminated is characterized by an absorption of less than 10% and an absolute hiding power of less than 10%.

Abstract: There is provided an optical plate. The optical plate includes a supporting substrate and an optical diffuser film. The optical diffuser film has a density of light scattering particles to provide light diffusion. The optical diffuser film has a surface facing the supporting substrate, wherein a first portion of the surface facing the supporting substrate contacts the supporting substrate. There exists a gap between a second portion of the surface facing the supporting substrate and the supporting substrate, wherein the ratio of the area of the first portion to the second portion is less than 10%.

Abstract: The invention features a bulk light diffuser material. The bulk light diffuser material may be a sheet or film comprising about 95 to about 99.8 percent by weight of polycarbonate and about 0.2 to about 2.5 percent by weight of a particulate light diffusing component, based on the total weight of the polycarbonate and the light diffusing particles. The sheet material has a percent transmittance of at least 70% and a haze of at least 10% measured according to the American Society for Testing and Materials (ASTM) standard D 1003.

Abstract: A process that is provided for agglomerating rubber particles of a rubbery latex. The process involves producing an agglomerating agent which is in the form of latex having particles which comprise high molecular weight polyoxyethylene bound therein. The agglomerating agent is affixed with an elastomeric latex to form agglomerated elastomeric particles. The process results in the formation of uniform size agglomerating particles, and utilizes a non-surfactant form of polyoxyethylene, which can be utilized in small amounts to yield the desired agglomerated elastomeric latex. The agglomerated particles may then be utilized as the substrate for graft copolymers, such as acrylonitrile-butadiene-styrene graft copolymers.
