Abstract
A coated wear resistant and transparent glass substrate has a multi-layer system with at least one layer of an oxynitride of one of hafnium, zirconium, tantalum and titanium, and with no metal layer. The substrate with multi-layer system has a reduced sun energy transmittance and anti-reflective effect in the visual spectral range.
