Patent ID: 7625626

Claim:
A light polarizing article comprising a light transmitting substrate having at least one surface, a light polarizing layer comprising an organic light polarizing dye, and a protective layer over the polarizing layer, an inorganic intermediate layer disposed between the substrate and the light polarizing layer, the inorganic intermediate layer having a first side abutting the light polarizing layer, the first side having a plurality of substantially parallel microgrooves and having a composition differing from that of the substrate, wherein the inorganic intermediate layer is formed by a material selected from the group consisting of oxides of Si, Al, Zr, Ti, Ge, Sn, In, Zn, Sb, Ta, Nb, V, Y, mixtures thereof, and combinations thereof, and wherein the oxides of silicon have a formula that is either SiO x , where x≧2, or SiO y , where 0.5≦y≦1.8, and wherein the organic light polarizing dye is deposited as a dye solution directly on the first side.
