Abstract
(DE)
Beschrieben wird ein Verfahren zur Bereitstellung einer metallisch spiegelnden, hochglänzenden Oberfläche auf einem Substrat, wobei zur Herstellung der metallisch spiegelnden Oberfläche auf das Substrat eine Schicht aus einem Primer aufgebracht wird, zwecks Bildung einer Silberschicht eine Silbersalzlösung mit einem Reduktionsmittel gemischt und auf die Primerschicht aufgesprüht wird, und auf die Silberschicht eine transparente oder transluzente Decklackschicht, vorzugsweise eine Klarlackschicht, aufgebracht wird. Der Primer enthält ein Korrosionsschutzmittel, welches ausgewählt ist aus der Gruppe umfassend Benzotriazol, Tolyltriazol, Benzimidazol, Derivate der genannten Verbindungen und Mischungen aus zwei oder mehr der genannten Verbindungen und/oder Derivate. Weiterhin werden ein gemäß dem Verfahren hergestelltes Schichtsystem und ein Substrat mit einem solchen Schichtsystem beschrieben.
(EN)
A method is described for providing a metallically reflective, high-gloss surface on a substrate, wherein, to produce the metallically reflective surface on the substrate: a layer of a primer is applied; a silver salt solution is mixed with a reducing agent and sprayed onto the primer layer to form a silver layer; and a transparent or translucent top lacquer layer, preferably a clear lacquer layer, is applied to the silver layer. The primer contains an anti-corrosion agent which is selected from the group comprising benzotriazole, tolyltriazole, benzimidazole, derivatives of the said compounds and mixtures of two or more of the said compounds and/or derivatives. Also described are a layer system produced using the method and a substrate having such a layer system.

L'invention concerne un procédé pour la réalisation d'une surface hautement brillante, à reflets métalliques sur un substrat, dans lequel, pour la fabrication de la surface à reflets métalliques, une couche d'un apprêt est appliquée sur le substrat, en vue de la formation d'une couche argentée, une solution de sel d'argent est mélangée avec un agent de réduction et pulvérisée sur la couche d'apprêt et une couche de laque de recouvrement transparente ou translucide, de préférence une couche de laque claire, est appliquée sur la couche argentée. L'apprêt contient un agent de protection contre la corrosion, qui est choisi dans le groupe comprenant le benzotriazole, le tolyltriazole, le benzimidazole, des dérivés des composés mentionnés et des mélanges de deux des composés et/ou des dérivés mentionnés ou plus. En outre, l'invention concerne un système à couches fabriqué selon le procédé et un substrat présentant un tel système à couches.
