Abstract
A glazing for motor vehicles is provided with at least one zone, in particular in the form of a filtering band attenuating the light radiation and the heat radiation in the upper area of the glazing. The filtering band is made with a transparent coating of a bakable enamel, which contains at least one nobel metal present in colloidal dispersion. The coating has a constant layer thickness, is applied by silk-screening and exhibits a geometrically exact screening on its entire surface. The degree of coverage of the screen is 85-95% in the area close to the edge.
