Abstract

The present invention, relates, to a process, for producing structured coatings, in which a coating composition comprising at least one inorganic binder, at least one oxide pigment which, after addition of a mixture consisting of 15 ml of 1 M oxalic acid and 15 ml of 20% aqueous hydrochloric acid based on 1 g of substance, under standard conditions, leads to a temperature rise of at least 4° C., and at least one solvent is applied to a substrate, the resulting coating composition film is partially coated with a photoresist and the substrate coated with the coating composition and the photoresist is treated with an acid, to the structured layers obtainable by the process and to the use thereof.
