ABSTRACT:
Describes a photochromic plastic article, e.g., an ophthalmic photochromic article, such as a lens, in which the article includes (1) a rigid substrate, e.g., 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 photochromic material, e.g., spirooxazine, naphthopyran and/or fulgide, and (3) a dendritic polyester acrylate film coherently appended to the photochromic coating. Describes also the aforedescribed photochromic article having an abrasion-resistant coating affixed to the dendritic polyester acrylate 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.
