发明名称 PHOTOCHROMIC OPTICAL ARTICLE.
摘要 <p>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 flugide, 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.</p>
