Abstract: An operating panel for a household appliance is provided with at least one user interface. The operating panel includes a planar support with an outer support surface facing an external region; a planar glass or glass-ceramic substrate with an outer substrate surface facing the external region and an opposite-lying inner substrate surface facing away from the external region and facing the outer support surface; a display element affixed to the support for luminous indication of information, which is preferably disposed on the outer support surface; and a sensor arrangement having at least two sensors, each of which comprises at least one electrode and is disposed on the inner substrate surface, for interaction with a user located in the external region.

Abstract: A method for producing a sol-gel ink, in particular from TEOS and MTEOS, is provided. The method includes adding inorganic particles as a filler and adding a high-boiling solvent.

Abstract: A substrate of glass or glass ceramics having a semitransparent coating is provided. The semitransparent coating has high scratch resistance, good temperature stability, and good adhesion on a sealing layer. The coating material has at least one sol-gel-based matrix, to which colorants are added, and that a polyester-functionalized and/or an epoxy-functionalized silicone resin, such as a polyester-modified silicone resin, is added to the sol-gel-based matrix.

Abstract: A method for producing a temperature-resistant, electrically conductive coating on a substrate is provided. The method includes at least the steps of providing a binding agent, the binding agent having an inorganically crosslinked, SiO2-containing binding-agent matrix; producing a dispersion of an electrically conductive pigment in the binding agent by mechanical convection, wherein the fraction of electrically conductive pigment amounts to 10 to 40 wt. %, and carbon is used as the electrically conductive pigment; partial, structured printing of the coating material obtained by dispersion onto the substrate; and drying the obtained coating at temperatures in the range of 20 to 250° C. Also provided are preparations for producing an electrically conductive coating on a substrate as well as substrates provided with electrically conductive coatings.
