Abstract
A transparent electrical conductor with a transparent substrate and an electrically conductive layer on the substrate are provided. The conductive layer has a plurality of electrically conductive nanoscale additives. The additives are in electrically conductive contact with one another, in order to form the electrically conductive layer. The substrate is formed from a glass or glass-ceramic material or a composite material having a glass and/or glass-ceramic. The additives are embedded in a matrix layer at least in some regions. The matrix layer is formed by a transparent matrix material. In order to make such a transparent electrical conductor useful, particularly for application in a display, as a touch sensor, or the like for cooking surfaces, the transparent electrical conductor exhibits a temperature resistance of at least 140° C. The additives are dispersed in a matrix material, which is applied as a coating material onto the substrate in one coating step.
