Abstract
An infrared radiation reflecting transparent layer system on a transparent substrate and a method for producing same is provided. The infrared radiation reflecting layer system comprises an infrared radiation reflecting layer sequence which includes a selective function usually consisting of a noble metal, mostly silver, or an alloy thereof and having a good selective reflectivity in the infrared range. The layer sequence is supplemented by at least one transparent dielectric layer of an oxynitride of a metal, a semiconductor or a semiconductor alloy having a low to moderate refractive index arranged directly on the substrate or above the infrared radiation reflecting layer sequence.
