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.
