Abstract

To produce functional vitrous, preferably colored or colloid-dyed layers, a composition produced by hydrolysis and polycondensation of PA1 (A) at least on hydrolyzable silane of general formula (I) EQU SiX.sub.4 (I) PA1 wherein the radicals X are the same or different and represent hydrolyzable groups or hydroxy groups, or an oligomer derived therefrom, and PA1 (B) at least one organosilane of general formula (II) EQU R.sup.1.sub.a R.sup.2.sub.b SiX.sub.(4-a-b) (II) PA1 wherein R.sup.1 is a non-hydrolyzable radical, R.sup.2 represents a radical carrying a functional group, X has the meaning given above, and a and b have the values 0, 1, 2 or 3, the sum (a+b) having the values 1, 2 or 3, or an oligomer derived therefrom PA1 with an (A):(B) substance ratio of 5-50:50-95, and optionally PA1 (C) one or more compounds of glass-forming elements, is mixed with at least one function carrier from the group of temperature-stable dyes or pigments, metallic or non-metallic oxides, coloring metallic ions, metallic or metallic compound colloids, and metal ions that react under reduction conditions to form metallic colloids; PA1 the composition mixed with the function carrier is applied onto a su…
