Process for manufacturing inductive counting systems
 A process is described for producing inductively operating counting systems by forming a conducting structure on an electrically non-conducting substrate, comprising a step involving the application of a suitable catalyst for the currentless deposition of metals onto the electrically non-conducting substrate as well as conventional pretreatment and post-treatment steps. The following process steps are essential for the process according to the invention: PA1 1) Application of a liquid photoresist, the liquid photoresist being printed only onto the surface not subsequently covered by the conductive pattern and onto the fine-structured portions of the conduction pattern, PA1 2) Subsequent photostructuring of the fine-structured portions of the conductive pattern by illumination and subsequent developing, PA1 3) Subsequent currentless deposition of a first thin metallic layer onto the exposed, catalytically coated surface regions, PA1 4) Subsequent electrolytic deposition of a second metallic layer onto the first metallic layer, and PA1 5) Subsequent application of a decorative protective lacquer or varnish film.
