Abstract: Dichroïc mirrors, also known as optical filters, having a particular use as a rear view mirror includes a vitreous substrate coated with a stack of interferential layers and with a metallic reflector. The stack of layers includes, successively from the substrate, a layer of high refractive index material in the range of 1.9 to 2.8, a layer of a lower refractive index material in the range of 1.2 to 2.2, and a layer of a semiconductor material having a refractive index of more than 3. The refractive indices of the layers of high refractive index material and lower refractive index material differ by at least 0.2 and the coated substrate has a transmittance at 550 nm of at least 6% and a reflectance at 550 nm greater than 45%.

Abstract: A composite article, in particular, a rear-view mirror for a motor vehicle, comprising a substrate generally made of glass, a reflective layer composed of an oxidized or nitrided metal, possibly in an under-stoichiometric state disposed on either the front face or the rear face, and a coating stack disposed on the front face. The coating stack comprises a layer having generally photocatalytic properties, preferably a titanium dioxide based layer, which may be covered by a fine hydrophilic layer. The coating stack may also comprise a barrier sub-layer. Preferably the hydrophilic layer and barrier sub-layer are composed of silicon oxide. A process for forming the composite article includes sputter deposition of various layers followed by heat treatment. Advantageously the article has an attenuated reflection which can vary between 40% and 75%.
