ABSTRACT:
The invention relates to rear projection screens comprising a light-scattering layer of a mixture of 95-5% by weight of a wax-like substance having a low light-scattering power, such as paraffin, and 5-95% by weight of a wax-like substance having a high light-scattering power, such as white bees wax or microcrystalline paraffin. The light-scattering layer may be attached to one transparent carrier, e.g. to a glass or synthetic resin plate, or may be positioned between two transparent carriers. The rear projection screens according to the invention have a fine grain structure, may be adjusted to optimum values of half value angle and resolving power, and are remarkably free from scintillation. Further, the invention relates to a process for preparing the rear projection screens.
