Abstract: The present invention relates to a roller device for treating sheet-form material, in particular for smoothing films (F*) or sheets, comprising a first roller unit 1 and a second roller unit 2, wherein each roller unit (1, 2) comprises: at least one drive motor with a motor moment of inertia JM, a roller (10, 20) with a roller moment of inertia JW, and at least one gear for the kinematic coupling of the roller (10, 20) to the at least one drive motor with a transmission ratio iMW between the at least one drive motor and the roller (10, 20), wherein the roller (20) of the second roller unit (2) is rotatable in the opposite direction to the roller (10) of the first roller unit (1), and wherein there is formed between the roller (10) of the first roller unit (1) and the roller (20) of the second roller unit (2) a first roller gap (40) through which the sheet-form material (F) is guided.

Abstract: A film comprising a matrix of transparent polymeric resin, and polymeric particles is disclosed. The particles are characterized in that their refractive index is different from that of the polymeric resin and in that their average particle size is 1 and 100 ?m. One surface of the film is structured its 60° gloss value is greater than 0.5 and smaller than 20%, and its roughness is greater than 3 and lower than 25 ?m. The other surface has a 60° gloss value greater than 50%. The film is suitable for use in flat screens.

Abstract: A thermoplastic composition suitable for making diffuser films is disclosed. The composition contains 90 to 99.95 percent of a transparent first polymeric resin and 0.01 to 10 percent particles of transparent second polymeric resin. The particles have a mean particle diameter of 1 to 100 ?m and their refractive index differs from that of the first polymeric resin. Not more than 500 ppm of said particles have particle diameters in the range of 80 to 200 nm.

Abstract: A composite systems (film laminates) useful for the in-mould decoration (IMD) process is disclosed. The composite comprise a first thermoplastic translucent plastics film having a thickness of from 20 to 1000 &mgr;m, a primer layer having a layer thickness of from 0.5 to 20 &mgr;m, a colored layer containing pigments and a plastics binder, and optional a second primer layer having a layer thickness of from 0.5 to 20 &mgr;m, which may be different from B), a layer of a thermoplastic polyurethane having a Shore A hardness of from 55 to 95, and a thermoplastic plastics film having a thickness of from 20 to 1000 &mgr;m, which may be different from the first plastic film.
