Patent ID: 7922847

Claim:
A process for making a light polarizing article, the process comprising the steps of: (a) providing a light transmitting substrate having at least one surface; (b) forming at least one adhesion-promoting inorganic sub-layer on the substrate; (c) depositing an inorganic intermediate layer directly over and abutting the at least one adhesion-promoting inorganic sub-layer, the inorganic intermediate layer having a first surface abutting the substrate and a second surface distal from the substrate, wherein the inorganic intermediate layer is different from the at least one adhesion-promoting inorganic sub-layer; (d) forming a plurality of micro-grooves on the second surface of the inorganic intermediate layer, wherein the plurality of microgrooves are substantially parallel to each other; (e) depositing an organic light polarizing dye directly onto the second surface to form a light polarizing layer over at least a portion of the second surface, wherein the organic light polarizing dye are deposited and confined in and aligned by the plurality of microgrooves; and (f) forming a protective layer over and abutting the light polarizing layer.
