ABSTRACT:
Process for the production of contact strips on substrates, especially on plates of mineral glass. These substrates are provided with an electrically conductive surface coating which is coated on the side facing away from the substrate with at least one surface layer of a dielectric material. For the production of the contact strips, a noble metal suspension in a liquid is deposited according to the invention on the surface layer in the pattern of the contact strips. Then the substrate with the pack of layers is exposed to a heat treatment at at least 100.degree. C. until a lowered total resistance occurs through the conductive surface coating between the contact strips.
