Reflector for vehicle rear view mirror, with hydrophilic- and attenuating properties, includes reflective layer with metal oxidized or nitrided sub-stoichiometrically

摘要

A substrate (10) carries a photocatalytic layer (40) based on titanium dioxide and a reflective layer (20) including a metal which is oxidized or nitrided sub-stoichiometrically. The layers are all disposed on the same face of the substrate. The reflective layer (20) is on the rear surface of the photocatalytic layer. A barrier layer (30) is included under the photocatalytic layer. The barrier layer (30) includes silica. A surface layer (50) is located on the front and includes silicon. Reflective layer thickness is 20-100 nm, preferably 30-60 nm. Photocatalytic layer thickness is 20-120 nm, preferably 40-75 nm. The surface layer thickness is 2-10 nm, preferably 3-6 nm. Visible reflectivity is 40-75%, preferably 40-70%. An Independent claim is included for the production of the reflector.
