摘要： Described are articles having an aminoplast resin photochromic coating prepared from an aminoplast resin, components(s) having hydroxyl functional groups and photochromic substances. The coatings exhibit a Fischer microhardness of from 45 to 180 Newtons per mm2 and desirable photochromic properties, i.e., the formation of darker activated colors and faster rates of photochromic activation and fade when irradiated with ultraviolet light. Also described are photochromic aminoplast resin articles.

摘要： A process for incorporating by thermal diffusion a photochromic substance into a synthetic organic host material is described. In the process, a surface of the host material containing a coating of a resin composition of from about 5 to about 50 parts of hydroxy (C.sub.2 -C.sub.3) alkyl cellulose, e.g., hydroxy propyl cellulose, and from about 95 to about 50 parts of poly(vinylpyrrolidone), which resin composition contains a photochromic substance, is heated to diffuse at least a portion of the photochromic substance into the surface of the host material. Subsequently, the coating is removed by washing with warm soapy water. In a particular embodiment, the host material is a polymer prepared from diethylene glycol bis(allyl carbonate).

摘要： 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 melting temperature of the photochromic substance for a time sufficient to transfer a photochromic amount of the photochromic material into the subsurface region of the plastic article, and thereafter removing the photochromic-lean resin film from the planar surface(s) of the plastic article.
