A solid sheet comprising transparent polycarbonate matrix, particles of a transparent polymer and an antistatic agent is disclosed. Characterized in that the refractive index of said matrix differs from that of said polymer, the sheet is suitable in making diffuser plate in flat screens.

Light-scattering sheet having high light transmission and improved antistatic properties

A multi-layer article is disclosed. The article contains a base layer that contains at least one thermoplastic resin and a second layer containing a thermoplastic (co)polyformal superimposed over the base layer. The (co)polyformal conforms to formulae (1) or (1), in which O-D-O and O-E-O independently denote a diphenolate group, -D- and -E- independently denote an aromatic group having 6 to 40 carbon atoms, k is a whole number from 1 to 1500, o stands for numbers from 1 to 1500, and m is z/o and n is (o-z)/o wherein z is 0 to o.

Polyformals as a coextrusion protective layer on polycarbonate

A thermoplastic compositions containing polycarbonate and a UV absorbing compound conforming to Formula 1 wherein R denotes a branched or unbranched alkyl group with 4 to 10 carbon atoms is disclosed. The composition is suitable for making molded or extruded articles, including multilayered articles exhibiting improved weatherability.

Compositions containing polycarbonate and novel UV absorbers

The present invention relates to a solid sheet prepared from a composition that includes: (a) a transparent polycarbonate; and (b) transparent polymeric particles having an optical density which differs from the transparent polycarbonate matrix material. The present invention also relates to use of such a solid sheet as a diffuser sheet in flat screens.

Light-scattering shaped articles of high light transmission and the use thereof in flat screens

A light-emitting, transparent, flexible film system based on polymers is produced by including a thermoplastic polyurethane film having an electroluminescent pigment incorporated therein in the flexible film system. These systems are useful as a luminescent system.

Light-emitting, transparent film system based on polymers

A transparent sheet having improved optical properties is disclosed. The sheet that features a deviation angle &#x3b1;(min) according to DIN 52305-A-AS of &#x2266;2.0 and a refracting power D(min) according to DIN 52305-A-AZ of &#x2266;0.05, is prepared by extruding a molding composition comprising linear (co)polycarbonate having weight average molecular weight of 25,000 to 31,000.

Molded polycarbonate articles having improved optical and processing properties

The present invention provides a process for surface finishing sheets made from thermoplastics by applying a partially fused layer of thermoplastic polyurethane.
