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.

Dependent claims

A process for producing a structured coating, comprising:

applying
a. a coating composition comprising
i. at least one inorganic binder,
ii. 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
iii. at least one solvent
to a substrate, to obtain a coating composition film on the substrate,
b. partially coating the resulting coating composition film with a photoresist, and
c. treating the substrate coated with the coating composition film and the photoresist with an acid resulting in a leaching out of said at least one oxide pigment from said coating composition film leaving a leached layer.
