Abstract: The invention relates to an optical article, for example, an ophthalmic lens, comprising at least one multilayer anti-reflective coating on a transparent substrate made from organic or mineral glass. Said coating comprises successively and starting at the substrate, a layer of material with high refractive index (HI), made from a hybrid organic/inorganic matrix within which are dispersed particles of mineral oxide or chalcogenide with a diameter of 2 to 50 nm and a layer of material with low refractive index (BI), obtained by hardening of a composition comprising at least one silane precursor (I) with 4 hydrolysable groups and at least one fluorosilane precursor (II), said second composition comprising at least 10% in mass of fluorine in a theoretical dry extract and with a molar ratio I/I+II greater than 80%.

Abstract: Optical lens comprises a substrate, a coating comprising at least a colorant sensitive to photodegradation and a protective coating (I) against the photodegradation (i.e. anti-UV coating) comprising at least a colorant sensitive to photodegradation, where (I) is obtained from a photopolymerization of acrylate oligomer and mono- or polyfunctional acrylate monomers, an UV absorber at 5-30 wt.% and a photoinitiator at 3-12 wt.%. An independent claim is included for: a process of manufacturing the optical lens, particularly colored and/or polarized lens comprising depositing the coating sensitive to photodegradation on a transparent substrate or a varnish coated substrate, optionally preparing a chemical surface on the obtained substrate, depositing (I), and photopolymerizing (I).

Abstract: La présente invention concerne un article optique, en particulier une lentille ophtalmique comprenant un substrat, un revêtement comprenant au moins un colorant sensible à la photodégradation, et un revêtement pour la protection contre la photodégradation (anti-UV) du revêtement comprenant au moins un colorant sensible à la photodégradation, le revêtement pour la protection contre la photodégradation comprenant un mélange d'oligomères acrylate et de monomères acrylate monofonctionnels ou multifonctionnels; au moins un absorbeur UV, et au moins un photoamorceur. Ce revêtement anti-UV utilisé est particulièrement adapté à une lentille ophtalmique dans laquelle la fonction polarisante est apportée par un système bicouche dont une couche comprend des cristaux liquides associés à des colorants, et plus particulièrement des colorants dichroïques. Avantageusement le revêtement anti-UV selon l'invention est combiné avec une couche barrière à l'oxygène.
