ARTICLE OPTIQUE COMPRENANT UN SUBSTRAT AYANT DES PARTICULES INCORPORÉES DESTINÉES À L'AMÉLIORATION DE LA RÉSISTANCE À L'ABRASION ET/OU AUX RAYURES

摘要

The invention relates to an optical article having a substrate made of an optical material comprising a polymer matrix and an improved abrasion and/or scratch resistance. The substrate comprises an external layer in which particles functionalized by a silane coupling agent are embedded into the polymer matrix, the Bayer value of said substrate determined in accordance with the ASTM F735-81 standard being at least 30 % greater than the Bayer value of the same substrate with no embedded particles.
