Substrates, in particular a substrate of glass, ceramic, plastic and metal and glazed or enamelled substrates, with a self-cleaning surface comprise an at least partly superficially hydrophobic structured (elevations and depressions) coating located on the substrate. Substrates according to the invention comprise particles with an average diameter of less than 100 nm, in particular 5 to less than 50 nm, for formation of the structure of the coating. Compositions according to the invention which are employed for the production of the structured coating of substrates according to the invention comprise, in addition to the structure-forming particles, a layer-forming material in a weight ratio of 100 : 1 to 1 : 2, in particular 20 : 1 to 1 : 1. In addition to having good self-cleaning properties, the coating is distinguished by its transparency. The use of the substrates is aimed in particular at the most diverse glass articles.
Substrat, en particulier un substrat en verre, c~ramique, plastique ou m~tal et substrat vitrifi~ ou ~maill~ poss~dant une surface auto-nettoyante et comprenant un revÚtement pr~sentant une structure au moins partiellement hydrophobe en surface (~l~vations et creux). Substrats comprenant des particules dont le diamtre moyen est inf~rieur ~ 100 nm, en particulier, de 5 ~ moins de 50 nm, servant ~ cr~er la structure du revÚtement. Compositions mises en application pour la fabrication du revÚtement structur~ de ces substrats et comprenant, en plus des particules constituant la structure, une matire constituant une couche selon un rapport en poids de 100:1 ~ 1:2, en particulier 20:1 ~ 1:1. En plus de ces propri~t~s auto-nettoyantes, ce revÚtement est caract~ris~ par sa transparence. Ces substrats sont utilis~s pour des articles vitrifi~s trs diversifi~s.
