COLOUR-NEUTRAL WEAR-RESISTANT COATING, SUBSTRATE WITH SUCH A NEUTRAL WEAR-RESISTANT COATING AND PROCESS FOR PRODUCING THE SAME

摘要

The present invention relates to a color-neutral wear protection layer for substrates. The invention also relates to a substrate with such a color-neutral wear protection layer and a method for its production. The substrate comprises glass or glass ceramic, the wear protection layer being formed over the entire surface or largely over the entire surface of at least one surface of the substrate and having a chromaticity in the CIELAB color system of C* is less than 14, preferably less than 7 and particularly preferably less than 4 when exposed to light, measured in remission with standard illuminant A or standard illuminant C or with blackbody radiation at a temperature between 2,500 K and 10,000 K, and the wear protection layer has a light transmittance in the visible wavelength spectrum of less than 60%, preferably less than 50% and particularly preferably less than 40%.
