Title (EN) ANTI-SCRATCH AND PHOTOCHROMIC COATING, RESPECTIVE METHOD OF APPLICATION AND USE
(FR) REVÊTEMENT ANTI-RAYURES ET PHOTOCHROMIQUE, PROCÉDÉ D’APPLICATION ET USAGE RESPECTIFS
Abstract:
(EN) The present application relates to an anti-scratch and photochromic coating, respective method of application and use. The main advantage of this coating is that it allows obtaining transparent lenses with high scratch resistance and able to develop, in a few seconds, a grey or brown colouration when exposed to the sun and with the ability to quickly revert to the initial colourless state when placed away from sun exposure. From a practical point of view, the coating now disclosed may be used in any type of material to which it is intended to confer anti-scratch and photochromic properties, such as ophthalmic lenses.
(FR) La présente invention porte sur un revêtement anti-rayures et photochromique, son procédé d’application et son usage respectifs. L’avantage principal de ce revêtement est qu’il permet l’obtention de lentilles transparentes très résistantes aux rayures et pouvant développer, en quelques secondes, une coloration grise ou marron lorsqu’elles sont exposées au soleil tout en pouvant revenir à leur état incolore initial lorsqu’elles ne sont plus exposées au soleil. D’un point de vue pratique, le revêtement selon la présente invention peut servir dans tout type de matériau auquel on prévoit d’attribuer des propriétés anti-rayures et photochromiques, par exemple des lentilles ophtalmiques.
