摘要： Described are photochromic polyurethane coatings that meet commercially acceptable “cosmetic” standards for optical coatings. Also described are articles having such coatings. The coatings exhibit a Fischer microhardness of from 50 to 150 Newtons per mm2 and improved photochromic properties, i.e., the formation of darker activated colors and faster rates of photochromic activation and fade when irradiated with ultraviolet light.

摘要： Described are articles having an aminoplast resin photochromic coating prepared from an aminoplast resin, component(s) having at least two different functional groups and photochromic substances. The coatings exhibit a Fischer microhardness of from 45 to 180 Newtons per mm2 and desirable photochromic properties, i.e., the formation of darker activated colors and faster rates of photochromic activation and fade when irradiated with ultraviolet light. Also described are photochromic aminoplast resin articles.
摘要翻译：描述了具有由氨基塑料树脂，具有至少两个不同官能团的组分和光致变色物质制备的氨基塑料树脂光致变色涂层的制品。涂层表现出45至180牛顿/ mm 2的菲舍尔显微硬度和所需的光致变色性质，即形成更暗的活化颜色和较快的光致变色激活速率和用紫外线照射时的褪色。还描述了光致变色氨基塑料树脂制品。

摘要： Describes a photochromic plastic article, e.g., an ophthalmic photochromic article, such as a lens, in which the article includes (1) a polymeric substrate, such as a thermoset or thermoplastic substrate, (2) a photochromic polymeric coating appended to at least one surface of the substrate, the photochromic polymeric coating containing a photochromic amount of at least one organic photochromic material, e.g., spirooxazine, naphthopyran and/or fulgide, and (3) a radiation-cured, acrylate-based film coherently appended to the photochromic coating, the acrylate-based film being (a) resistant to removal by aqueous solutions of inorganic caustic, e.g., potassium hydroxide, (b) compatible with organo silane-containing abrasion-resistant coating, and (c) harder than said photochromic coating. Describes also the aforedescribed photochromic article having an abrasion-resistant coating affixed to the radiation-cured acrylate-based film, e.g., an abrasion-resistant coating comprising an organo silane; and a photochromic article having an antireflective coating affixed to the abrasion-resistant coating.
