Method for producing a layer structure using a paste on the basis ofa resistive alloy

Method for producing a layer structure comprising the successive steps:

• a. Providing a substrate having a glass or ceramic surface,
• b. Applying a paste A to at least a portion of the glass or ceramic surface of the substrate to obtain a layer of paste A, wherein paste A contains the following constituents:
• I. a glass frit containing at least two mutually different elements as oxides and having a transformation temperature Tg in the range of 600 to 750° C., and
• II. an organic medium,
• c. Drying and, if necessary, burning of the layer of paste A
• d. Applying a paste B to at least part of the layer from step c. to obtain a layer of paste B, wherein paste B contains the following constituents:
• I. A resistance alloy powder having an electrical resistance temperature coefficient of less than 150 ppm/K
• II. an organic medium,
• III. 0-15% by weight glass frit, based on the total weight of paste B, and
• e. Burning and optional drying of the layers of paste B before burning.
