Abstract

A METHOD OF IMPARTING A PHOTOCHROMIC RESPONSE TO A SYNTHETIC PLASTICS ARTICLE COMPRISES: (A) APPLYING A SUBSTANTIALLY MOTTLE-FREE, SUBSTANTIALLY HOMOGENEOUS FILM OF POLYMERIC RESIN, HAVING A PHOTOCHROMIC MATERIAL DISSOLVED THEREIN ONTO AT LEAST ONE PRINCIPAL SURFACE OF THE PLASTICS ARTICLE; (B) HEATING THE FILM-BEARING PLASTICS ARTICLE AT TEMPERATURES NEAR TO BUT BELOW THE MELTING TEMPERATURE OF THE PHOTOCHROMIC MATERIAL FOR A TIME SUFFICIENT TO INCORPORATE A PHOTOCHROMIC AMOUNT OF THE PHOTOCHROMIC MATERIAL INTO THE SUBSURFACE OF THE PLASTICS MATERIAL; AND(C) THEREAFTER REMOVING THE PHOTOCHROMIC-LEAN FILM FROM THE SURFACE OF THE PLASTICS ARTICLE.PHOTOCHROMIC ARTICLES PREPARED BY THIS METHOD ARE USEFUL IN OPTICAL APPLICATIONS SUCH AS LENSES,FILTERS AND AUTOMOTIVE WINDSHIELDS.
