The present invention relates to a process for producing a porous layer adhering to a substrate, which comprises the steps: a. preparation of a composition comprising an organic polymer constituent and an inorganic-organic constituent and/or an inorganic constituent, b. application of this composition to a substrate and formation of a layer on the substrate, and c. removal of the inorganic-organic constituent and/or the inorganic constituent from the layer to form a porous layer adhering to the substrate.
