Title (EN) LOW-REFRACTIVE INDEX LAYER, AR COATINGS HAVING SUCH A LAYER AND METHODS FOR PRODUCING THEM
(FR) COUCHE A FAIBLE INDICE DE REFRACTION, REVETEMENTS ANTIREFLETS OBTENUS, ET PROCEDES DE FABRICATION
Abstract:
(EN) A low refractive index layer for anti-reflection film applications includes a fluorinated copolymer as the principal low refractive index material. The fluorinated copolymer is soluble in a non-halogenated organic solvent, enabling deposition of the low refractive index layer of uniform thickness onto conventional substrates via conventional wet coating processes, but without the need for or use of expensive and environmentally unfriendly halogenated solvents. Coating compositions for depositing such a low refractive index layer and methods of depositing them also are disclosed.
(FR) La présente invention concerne une couche à faible indice de réfraction destinée aux applications des films antireflets. Le principal matériau à faible indice de réfraction de cette couche est un copolymère fluoré. Ce copolymère, soluble dans un solvant organique non halogéné, permet le dépôt d'une couche de faible indice de réfraction d'épaisseur uniforme sur des substrats conventionnels par un traitement conventionnel d'application humide, mais sans nécessiter de solvants solvant halogénés dispendieux et peu écologiques. L'invention concerne également les compositions d'application de telles couches, et les procédés d'application correspondants.
