Abstract
ABSTRACT OF THE DISCLOSURE Described is a method for imparting a photochromic response to a synthetic plastic article, e.g., an optical lens such as a sunglass lens prepared from an allyl diglycol carbonate monomer. The method described comprises depositing a thin uniform substantially dry film of a photochromic-bearing polymeric resin onto at least one planar surface of the synthetic plastic material, heating the plastic article and resin film substantially uniformly at temperatures near to but below the melt-ing temperature of the photochromic substance for a time sufficient to transfer a photochromic amount of the photochromic material into the sub-surface region of the plastic article, and thereafter removing the photochromic-lean resin film from the planar surface(s) of the plastic article.
