    摘要： 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 μm, 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 μm, 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 0.2, and where the total concentration of the spherical scattering particles (A) and particles (B) is in the range from 1 to 60% by weight, based on the weight of the light-scattering polymethyl methacrylate layer, where the concentration of the spherical scattering particles (A) cPA, the thickness of the light-scattering polymethyl methacrylate layer dS and the size of the spherical scattering particles (A) DPA is selected in such a way that the ratio cPA*dS/DPA3 is in the range from 0.001 to 0.015% by weight*mm/μm3, the concentration of the spherical particles (B) cPB, the thickness of the light-scattering polymethyl methacrylate layer dS and the size of the spherical particles (B) DPB is selected in such a way that the ratio cPB*dS/DPB3 is in the range from 0.000005 to 0.002% by weight*mm/μm3 and the ratio of the square of average surface roughness of the polymethyl methacrylate layer RZ to the third power of the size of the spherical particles (B) RZ2/DPB3 is in the range from 0.0002 to 0.1300 μm−1.

    摘要： 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.
