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： Inorganic photochromic crystalline particles which are particularly useful in ophthalmic quality plastic host materials are formed for instance utilizing a silver halide crystal whose dimensions lie generally in the range between 30 Angstroms and 10,000 Angstroms. The surface of the silver halide crystal is coated with an inorganic material in an effective thickness to render the coating resistant to diffusion from within and to protect the crystal from interaction with host material. The stabilized coated particles can be introduced by known schemes into plastic host materials in order to form photochromic plastic articles useful in the preparation of films, sheets, filters for cameras, wall panels and ophthalmic lenses and other optical devices.

摘要： The organic photochromic composition of this invention comprises spiro [indoline-2,3'-[3H]-naphth [2,1-b] [1,4] oxazine] (SO) dye and an unconventional ultraviolet stabilizer. The ultraviolet stabilizer improves the light fatigue resistance of the SO dye and will not hinder the photocolorability of the photochromic composition.

摘要： Laser protection is provided by utilizing certain organic polymers with carboxylic or sulfonic acid groups which exchange their protons with cupric or ferrous metal ions to form cupric or ferrous ion-containing polymers. In addition, laser protection is also provided utilizing organic polymers with functional groups which are capable of forming complexes with cupric or ferrous metal ions. The optical absorption of the metal ions (e.g., the transition metal and rare earth ions) in these two types of metal ion-containing polymers are similar to those in absorbing glasses and will provide absorption in the near IR portion of the spectrum (i.e., greater than 680 nm). Thus, metal ion-containing polymers can be as useful for laser eye protection as known absorbing glasses, while providing high visual transmittance and light weight.
摘要翻译： 通过利用具有羧酸或磺酸基团的某些有机聚合物来提供激光保护，其用铜或黑色金属离子交换其质子以形成含铜或含亚铁离子的聚合物。 此外，还提供了利用能够与铜或黑色金属离子形成络合物的官能团的有机聚合物来提供激光保护。 这两种含金属离子的聚合物中的金属离子（例如过渡金属和稀土离子）的光吸收与吸收玻璃相似，并将在光谱的近IR部分提供吸收（即， 大于680nm）。 因此，含金属离子的聚合物可以像已知的吸收眼镜一样用于激光眼睛保护，同时提供高的视觉透光率和轻的重量。

摘要： An organic photochromic composition comprising spiro [indoline-2,3'-[3H]-naphth [2,1-b] [1,4] oxazine] dye (spirooxazine dye) and unconventional ultraviolet stabilizers. The ultraviolet stabilizers improve the light fatigue resistance of the spirooxazine (S.O.) dye and will not hinder the photocolorability of the photochromic composition. The unconventional ultraviolet stabilizers belong to the class of hindered amine light stabilizers (HALS) and excited state quenchers.
