DECORATIVE MATERIAL AND METHOD FOR MANUFACTURE OF DECORATIVE MATERIAL Russian patent published in 1998 - IPC

FIELD: manufacture of material for producing continuous optically anisotropic film. SUBSTANCE: decorative material has phase delaying plate including continuous layer of optically anisotropic material with portions differing in phase incursion value and/or direction of quick optical axis, or including continuous optically homogeneous anisotropic material, or it has reflective surface instead of one of polarizers. Method involves forming mosaic structure by embossing optically anisotropic polymeric film or by local thermal heating of optically anisotropic polymeric film. EFFECT: simplified method and increased efficiency. 10 cl, 5 dwg
