Process for making contact bands on substrates, especially on panes, and panes made by this process

Method for producing contact tracks (2, 3) on substrates (6), in particular on discs of mineral glass. These substrates are provided with an electrically conductive surface coating (8), which is coated on the side facing away from the substrate (6) with at least one surface layer (9) made of a dielectric material. To produce the contact tracks (2 and 3), according to the invention, a noble metal suspension in a liquid is applied to the surface layer (9) in accordance with the course of the contact tracks (2, 3). Subsequently, the substrate (6) with the layer package is subjected to a temperature treatment at at least 100 ° C until a reduced total resistance occurs by the conductive surface coating (8) by means of the contact tracks (2, 3).
