Substrates with a self-cleaning surface, a process for their production and their use

A coated substrate, comprising:

• a coating disposed on a glass, ceramic, plastic or metal substrate, or disposed on a glazed or enamelled substrate, the coating comprising nanoscale structure-forming particles that form a surface structure that is at least partly hydrophobic, and the nanoscale structure-forming particles have an average diameter of less than 100 nm, and the coating further comprising an inorganic or organic layer-forming material that binds the structure-forming particles to the substrate;
• and the coating further comprises micro-scale structure-forming particles having an average diameter in a range of from about 0.1 micrometers to about 50 micrometers, the micro-scale structure-forming particles being contained in a same first layer as the nanoscale particles, or in an optional second layer that is disposed underneath the first layer, whereby the micro-scale structure-forming particles support the nanoscale structure-forming particles that are disposed thereon.
