Abstract

The present invention relates to a process for the production of a layer composition (10) with an electrically conductive layer (11), comprising the process steps: a) provision of a substrate (12) with a substrate surface (13); b) formation of a polymer layer (14) comprising an electrically conductive polymer (15) on at least a part of the substrate surface (13); c) application of a liquid stabilizer phase, comprising a stabilizer and a liquid phase, to the polymer layer (14) from process step b), wherein the stabilizer phase comprises less than 0.2 wt. %, based on the stabilizer phase, of the electrically conductive polymer, wherein the stabilizer is an aromatic compound with at least two OH groups, and a layer composition (10) and uses thereof.
