Title: (EN) PHOTOCHROMIC COATING COMPOSITIONS, METHODS OF MAKING COATED ARTICLES AND ARTICLES THEREOF
(FR) COMPOSITIONS DE REVETEMENT PHOTOCHROME, PROCEDES DE PRODUCTION D'ARTICLES REVETUS ET ARTICLES PRODUITS
Abstract:
(EN) Described are ungelled coating compositions of photochromic material, precursor materials for a first polymer polymerizable by free-radical initiated polymerization and precursor materials for a second or additional polymer(s) different from the first polymer. When the second polymer is selected from polyurethane, poly(urea-urethane) and mixtures thereof, the precursor materials include at least one blocked polyisocyanate. Also described are methods of making photochromic articles using the ungelled coating compositions and the photochromic articles produced using these methods.
