摘要:
Describes a photochromic article, e.g., an ophthalmic photochromic plastic article, such as a lens, in which the article includes (1) a rigid substrate, e.g., a transparent substrate such as a glass or organic polymeric substrate, as for example, a thermoset or thermoplastic substrate, (2) a photochromic polymeric coating appended to at least a portion of 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, diarylethene and/or fulgide, and (3) a thermally cured transparent thermoset polymeric coating superposed on, e.g., coherently appended to, the photochromic coating, the thermally cured polymeric coating being harder than the photochromic polymeric coating. Describes also the aforedescribed photochromic article having an abrasion-resistant coating affixed to the thermally cured polymer coating, e.g., an abrasion-resistant coating comprising an organo silane; and a photochromic article having an antireflective coating affixed to the abrasion-resistant coating.
