Abstract

Enamel-like coatings consisting of glass frits and pigments are used for auto glass panes. An improved opacity of these enamel layers relative to silver conducting tracks on these layers is achieved if 0.1 to 10% by weight silicon, boron, carbon, lead and/or silver in elemental form are added to the enamel.
