MATERIAL FOR PROJECTION SCREEN Russian patent published in 1997 - IPC

FIELD: movie and photographic equipment. SUBSTANCE: material for projection screen includes backing 1 with mirror-metallized surface 2 connected with the aid of color-carrying binder 4 to layer of transparent polymer film 6 with light-scattering stamping. Solid solution of luminophor particles of at least one luminescence color in binder with concentration 0.4-20.5 volume per cent is used as color-carrying binder, concave spherical bends 7 having depth 0.5-500.0 $$$ formed in thermoplastic polymer film are used in the capacity of light-scattering stamping. Backing can be made from thermoplastic polymer with mirror-metallized surface 2 with assemblage of reflecting lenses in the form of concave spherical bends having depth 0.5-500 $$$. EFFECT: facilitated manufacture, increased operational efficiency of screens made from this material. 1 cl, 2 dwg
