this invention is directed to the production of laminated , transparent , polarizing glass articles . the inventive method contemplates five basic steps : forming parallel microgrooves on a surface of a glass support ; washing and drying said surface ; depositing on said surface a mixture of organic colorants corresponding to the three primary colors and exhibiting a nematic state to yield a coating displaying polarizing properties ; treating the polarizing coating with an aqueous solution of inorganic salts having an acid ph ; and applying a continuous , optically transparent , composite film upon the polarizing coating and bonding it thereto .
