摘要:
Coating with photochromic properties, method for producing said coating and use thereof applicable to optical articles and glazed surfaces. The coating is formed by the combination of the following three elements: (1) a polymeric matrix, which is typically rigid and deposited on the surface of interest; (2) hollow, sealed micro- and/or nanocapsules dispersed within said matrix; and (3) solutions of photochromic compounds (chosen from a group comprising spirooxazine, azobenzenes or chromenes) in a liquid solvent that does not react (with the photochromic compound and with the capsule wall), which are encapsulated inside said micro- or nanocapsules.
