Glass ceramic and metal substrates with a self-cleaning surface, method for the production and use thereof
First Claim
1. A glass, ceramic or metal substrate with at least one self-cleaning surface comprising a layer with a micro-rough surface structure which is arranged on the substrate and made at least partly hydrophobic, characterised in that the layer contains a glass flux and structure-forming particles with a mean particle diameter within the 0.1 to 50 μ
- m range, the glass flux and structure-forming particles are present in a volume ratio within the 0.1 to 5 range, and the micro-rough surface structure has a ratio of mean profile height to mean distance between adjacent profile tips within the 0.3 to 10 range.

Abstract
The invention relates to glass, ceramic and metal substrates with at least one self-cleaning surface, comprising a layer with a micro-rough surface structure which is arranged on the substrate and made at least partly hydrophobic. The layer contains a glass flux and structure-forming particles with a mean particle diameter within the 0.1 to 50 μm range; the glass flux and structure-forming particles are present in a volume ratio within the 0.1 to 5 range, and the micro-rough surface structure has a ratio of mean profile height to mean distance between adjacent profile tips within the 0.3 to 10 range.
To produce the subject of the invention the substrate is coated with a composition containing a glass flux and structure-forming particles, and the layer is burnt in and made hydrophobic.
