    摘要: Organic photochromic materials comprise a photochromic pigment stabilized with a protective inorganic coating which serves to protect the pigments from deactivation by exposure to moisture, oxygen, various plastic host materials, reactive chemicals or even normal atmospheric conditions. Useful organic photochromic pigments include the anils, hydrazones, semicarbozones, osazones, sydnones, fulgides and others. Inorganic coatings comprising such materials as zinc oxide, titanium dioxide, aluminum oxide, antimony oxide and silicon dioxide are useful in the preparation of photochromic plastic films, sheets, ophthalmic lenses such as lenses for sunglasses and in camera lenses and filters.

    摘要: Organic photochromic materials comprising a photochromic dye and a resinous material can be stabilized with a protective coating which will protect them from deactivation by exposure to moisture, oxygen, various plastic host materials, reactive chemicals or even normal atmospheric conditions. Useful organic photochromic dyes include the spiropyrans, the spirooxazines, the metal dithizonates, the phenazines, the phenothiazines and other known photochromic compositions. Useful resinous materials include vinyl-type thermoplastics, cellulosic materials, polyesters, epoxy resins and aminoplast resins. The encapsulated photochromic materials of the invention comprise an organic photochromic dye in combination with an organic resinous material enclosed within an outer shell of an inorganic material and find use in the preparation of photochromic plastic films, sheets, ophthalmic lenses such as lenses for sunglasses and in camera lenses and filters.

    摘要: A lens having an optical density which is variable under differing light conditions can be produced by imbibing a synthetic polymer lens such as a polycarbonate or diethylene diglycol bis allyl carbonate polymer with a solution of a metal dithizonate. A polarizing sheet can be laminated thereto or alternatively, a passive dye can be utilized on the inner surface of the lens to provide non-variable reduced optical density in the assembly.

    摘要: A method for producing photochromic plastic materials is disclosed which is characterized by forming a transparent polymeric shape from a mixed polymer consisting of a polyester resin made by esterification of an unsaturated polybasic organic acid with a polyhydric alcohol, and a polar vinyl monomer, swelling a surface layer of the cured polymeric shape with a polar solvent, absorbing silver and halide ions into the swelled surface layer, and collapsing the swelled surface layer.
