Zusammenfassung:	UV curable coating composition comprising a non hydrolyzed epoxy- alkoxy-silane, polyfunctional acrylate and/or epoxy compounds and a cationic and/or free-radical photo-initiator; with polyfunctional acrylate and/or epoxy compounds representing more than 40 weight% of the total dry matter and the composition being without any hydrolysed epoxy-alkoxy-silane. This composition is coated and cureed on an optical substrate. Composition de revêtement durcissable aux UV comprenant un époxy-alcoxysilane non hydrolysé, un acrylate polyfonctionnel et/ou des composés époxy et un photo-initiateur cationique et/ou à radical libre; l'acrylate polyfonctionnel et/ou les composés époxy représentent plus de 40% du poids de la matière sèche totale, la composition ne contenant aucun époxy-alcoxysilane hydrolysé. Cette composition est appliquée et durcie sur un substrat optique.
