    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 light guide plates, which are suitable for backlighting LCD monitors as well as information and advertising signs and which are illuminated at the edges and re-emit the light fed at the edges via at least one of the two surfaces located perpendicular to the edges. For the light of a light source that is fed at the edges to be able to leave the light guide plate again via one of the surfaces by overcoming total reflection, the light rays in the light guide plate have to be deliberately deflected. At one of the two surfaces of the light guide plate, the light guide plates are provided with optical impurities (2), which are protected against damage by a film (5). Furthermore, a method for the simplified application of said impurities is provided.
