Process for the production of a layer composition

The present invention relates a process for the production of a layer composition 9, comprising the process steps: (a) provision of a substrate 10 with a substrate surface 11; (b) formation of a stabilized electrically conductive polymer layer 12 on at least a part of the substrate surface 11, the formation of the stabilized electrically conductive polymer layer 12 comprising the process steps: (b1) formation of an electrically conductive polymer layer 13 comprising an electrically conductive polymer on at least a part of the substrate surface 11; (b2) application of a liquid stabilizer phase, comprising at least one stabilizer 7 and at least one solvent or dispersant, onto the electrically conductive polymer layer 13 obtained in process step (b1) for the formation of a stabilizer layer 14, wherein the at least one stabilizer 7 is a flavonoid. The present invention also relates to a layer composition and to the use of a layer composition.
