Title (EN) ELECTROCHROMIC COMPOUNDS AND OPTICAL ARTICLES CONTAINING THEM
(FR) COMPOSÉS ÉLECTROCHROMES ET ARTICLES OPTIQUES CONTENANT CES DERNIERS
Abstract:
(EN) The present invention relates to a group of novel electrochromic compounds. More specifically, it relates to electrochromic compounds comprising one or several pyridinium rings and the use of these compounds as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.
(FR) La présente invention concerne un groupe de nouveaux composés électrochromes. Plus spécifiquement, l'invention porte sur des matériaux électrochromes comprenant un ou plusieurs cycles pyridinium et sur l'utilisation de ces composés en tant que milieu à transmittance variable pour la fabrication d'un article optique, tel qu'une lentille ophtalmique.
