Abstract

Electrotechnical thin layers usable as heating resistance and/or substrate for conductor layers are produced at high cost and extremely slowly in the established methods. Industrial-scale methods that provide sufficient speed at room temperature are not available.This problem is solved by a room temperature printing process, wherein a redox-reactively deposited, graphite-containing base layer printed at room temperature is obtained, onto which a metal, by redox reaction during print, forms a metal layer in the micrometer scale within minutes to a few seconds in a corresponding manner.The double layer thus obtainable in one printing process is highly flexible, allows soldering to copper layers, and can be used particularly advantageously as a thin-layer heater.
