ABSTRACT:
Disclosed are novel light polarizing articles comprising a substrate, a light polarizing layer, an inorganic intermediate layer between the polarizing layer and the substrate, an optional inorganic sub-layer between the substrate and the inorganic intermediate layer, and a protective layer over the light polarizing layer, and method of making the same. Due to the presence of the inorganic intermediate layer and the optional sub-layer, adhesion of the polarizing layer is improved substantially. The light polarizing article has improved chemical, mechanical and thermal resistance. The light polarizing article can be used, for example, as ophthalmic products and in display devices.
