Abstract
A reflector with high total reflection which is resistant to mechanical stresses. The reflector comprises a reflector body and superimposed thereon (a) a functional coating such as a varnish, (b) a reflecting layer structure composed of a reflecting metallic layer and optionally arranged thereon one or several transparent ceramic layers, for example, layers having an optical depth of λ/2. The reflecting layer structure contains, as its surface layer, a protective layer. The protective layer is a silicon oxide of general formula SiO, wherein x is a number from 1.1 to 2.0, or it is aluminum oxide of formula AlO, in a thickness of 3 nm or more. The protective layer protects the underlying layers from mechanical damages. In the DIN 58196 abrasion test the protected surface does not show any damages after 50 test cycles with 100 abrasion strokes.
