DICHROIC LIGHT POLARIZER Russian patent published in 1999 - IPC

FIELD: organic dyes. SUBSTANCE: invention relates to dichroic light polarizers based on polymer organic dyes which can be used under severe production or operation conditions, e.g. in automotive industry when manufacturing laminated windshields, in lighting equipment, in glass production, building, etc. , that is where utilization of conventional light polarizers is impossible because of their low thermal and radiation resistance as well as of their high price. Polarizer of invention containing polarizing coating constituting, applied on a carrier, molecularly regular film of polymer organic dye or mixture of dyes capable of forming liquid-crystal phase. EFFECT: improved polarization characteristics. 1 dwg, 1 tbl, 36 ex
