Presently described are (e.g. brightness enhancing film) optical articles comprising the reaction product of a polymerizable resin and surface modified inorganic nanoparticles, methods of surface modifying inorganic nanoparticles, and surface modified inorganic nanoparticles. The surface treatment comprises at least one monocarboxylic acid having a refractive index of at least 1.50 and/or at least one monocarboxylic acid having a Mn of at least 200 g/mole and an ethylenically unsaturated group and/or at least one dicarboxylic acid.

[EN] Presently described are (e.g. brightness enhancing film) optical articles comprising the reaction product of a polymerizable resin and surface modified inorganic nanoparticles, methods of surface modifying inorganic nanoparticles, and surface modified inorganic nanoparticles. The surface treatment comprises at least one monocarboxylic acid having a refractive index of at least 1.50 and/or at least one monocarboxylic acid having an Mn of at least 200 g/mole and an ethylenically unsaturated group and/or at least one dicarboxylic acid. [FR] La présente invention concerne des articles optiques (par exemple un film augmentant l'éclat) comprenant le produit de réaction d'une résine polymérisable et de nanoparticules inorganiques dont la surface a été modifiée, des procédés de modification de la surface de nanoparticules inorganiques et des nanoparticules inorganiques dont la surface a été modifiée. Le traitement de surface comprend au moins un acide monocarboxylique ayant un indice de réfraction d'au moins 1,50 et/ou au moins un acide monocarboxylique ayant une Mn d'au moins 200 g/mole et un groupe éthyléniquement insaturé et/ou au moins un acide dicarboxylique.
