Title
(EN) OPTICAL ARTICLE INCLUDING AN ANTIREFLECTION COATING HAVING IMPROVED CRACK-RESISTANCE PROPERTIES UNDER MECHANICAL STRESS
(FR) ARTICLE OPTIQUE COMPRENANT UN REVÊTEMENT ANTI-REFLETS AYANT DES PROPRIÉTÉS DE RÉSISTANCE AUX FISSURES SOUS CONTRAINTE MÉCANIQUE AMÉLIORÉE
Abstract
(EN)
The invention relates to an optical article including a transparent organic glass substrate, a primary coating including polyurethane and particulate silica, an abrasion-resistant coating, and an antireflection coating, said coatings, and in particular the antireflection coating, having improved crack resistance when the optical article is subjected to high amounts of mechanical stress, e.g., during edge-grinding and the mounting of lenses in eyeglass frames. The invention also relates to a method for manufacturing such an article.
(FR)
Article optique comprenant un substrat transparent en verre orga¬ nique, un revêtement primaire comprenant du polyuréthane et de la silice particulaire, un revêtement anti-abrasion, et un revêtement an¬ ti-reflets, lesquels revêtements, et en particulier le revêtement an¬ ti-reflets, possèdent une résistance améliorée aux fissures lorsque l'article optique subit de fortes contraintes mécaniques, comme par exemple lors des étapes de débordage et de montage des verres dans les montures de lunettes. L'invention concerne également un procédé de fabrication d'un tel article.
