Title
(DE) Beschichtung für den Anzeigebereich von Glas- oder Glaskeramik-Scheiben, Verfahren zur Herstellung einer solchen Beschichtung und deren Verwendung
(EN) Coating for the display area of glass or glass-ceramic panes, method for producing such a coating and its use
(FR) Revêtement pour la zone d'affichage de plaques de verre ou de vitrocéramiques, procédé de fabrication d'un tel revêtement et son utilisation
Abstract
(DE)
Transparente Beschichtung, das Verfahren zur Herstellung der Beschichtung und ihre Verwendung für Anzeigebereiche von flächig beschichteten Glas- oder Glaskeramik-Scheiben, wobei die transparente Beschichtung der Anzeigebereiche in Aussparungen der flächigen, nichttransparenten Beschichtung als Sol-Gel-Farbe mit Alkylsilicaten als Filmbildner angeordnet ist und die aus dem Filmbildner durch thermische Behandlung entstandene Beschichtung über die reaktiven Gruppen der Alkylsilicate, vernetzt ist und direkt an das Silicium gebundene, organische, nicht hydrolisierbare Reste aufweist.

(EN)
Transparent coating for display areas of flat-coated glass or glass-ceramic discs, is claimed. The transparent coating is arranged in recesses of the flat, non-transparent coating as sol-gel-dye with alkyl silicate as film former, where the coating resulting from the film former by thermal treatment is linked via the reactive groups of the alkyl silicate and directly bonded to the silicon, exhibits organic, non-hydrolyzable radicals. An independent claim is also included for producing the transparent coating, comprising applying the transparent coating in recesses of the flat, non-transparent coating as sol-gel-dye with alkyl silicate as film former, where the formation of the transparent coating by a thermal treatment of the applied dye is carried out at = 200[deg] C.
