Abstract

L’invention concerne, d’une part, un revêtement multicouche à propriétés, notamment, antireflets et antibuée pour vitrages de véhicules automobiles, comprenant au moins deux couches minces, respectivement une couche interne et une couche externe, caractérisé en ce que ladite couche externe présente un fort indice de réfraction tandis que ladite couche interne présente un faible indice de réfraction et est composée d’agents hydrophobes destinés à réduire sa tension de surface de façon à éviter à la fois l’apparition de buée et son encrassement et, d’autre part, un procédé de réalisation dudit revêtement Figure pour l’abrégé : Figure 1The invention relates, on the one hand, to a multilayer coating with properties, in particular, anti-reflective and anti-fog for motor vehicle windows, comprising at least two thin layers, respectively an inner layer and an outer layer, characterized in that said outer layer has a high refractive index while said inner layer has a low refractive index and is composed of hydrophobic agents intended to reduce its surface tension so as to avoid both the appearance of fogging and its fouling and, of on the other hand, a method of producing said coating Figure for the abstract: Figure 1
