Abstract
The invention relates to a coated article which has (i) at least one electrically non-conducting base layer, (ii) at least one layer of copper and/or a copper alloy, and (iii) a layer which contains at least one electrically conductive polymer, wherein the copper or copper alloy layer (ii) is positioned between the base layer (i) and the layer containing the conductive polymer (iii), and which is characterized in that the layer (iii) contains at least one precious metal or at least one semiprecious metal or a mixture thereof. The invention also relates to a process for its production and also its use for the prevention of corrosion and to preserve the solderability of printed circuit boards.
