  • Publication number: 20080138610
    Abstract: The invention relates to a process for production of foils or sheets composed of thermoplastic with electrically conductive coating by means of the following steps of a process: a) single-side coating of a backing foil composed of a thermoplastic with a lacquer composition based on silicon and comprising inorganic semiconductor particles, b) extrusion of an extrudate of a thermoplastic, c) bringing the coated side of the backing foil and the extrudate of the extruded thermoplastic together in the nip of the polishing stack, d) peeling of the backing foil from the composite, whereupon the coating of the backing foil remains on the extruded thermoplastic, e) if appropriate, cooling of the plastics web to ambient or room temperature. The invention further relates to the extruded and coated foils and sheets, and also to their uses.

  • Publication number: 20070197703
    Abstract: The present invention relates to a foil encompassing at least one PMMA layer coloured with a yellow anthraquinone dye, where the chromaticity coordinates (x;y) in the CIE 1931 Standard Colorimetric System of the PMMA layer are within the range of 0.4?x?0.54 and 0.44?y?0.54, where the concentration of the yellow dye of the PMMA layer is at least 3% by weight, based on the total weight of the PMMA layer.

  • Publication number: 20060209403
    Abstract: The present invention relates to a rear-projection screen encompassing at least one light-scattering polymethyl methacrylate layer, which comprises a polymethyl methacrylate matrix and spherical scattering particles (A) and spherical particles (B) with a different median particle size V50, where the spherical scattering particles (A) have a median size V50 in the range from 0.1 to 40 ?m, the difference between the refractive index of the spherical scattering particles (A) and that of the polymethyl methacrylate matrix being in the range from 0.02 to 0.2, where the spherical particles (B) have a median size V50 in the range from 10 to 150 ?m, the difference between the refractive index of the spherical particles (B) and that of the polymethyl methacrylate matrix being in the range from 0 to 0.
