Claim 14:
15. An aqueous dispersion, containing
A) at least 15 wt. %, but no more than 40 wt. %, of silicates dissolved in water, calculated as SiO2;
B) at least 4 wt. %, but no more than 15 wt. %, of sodium and/or potassium ions dissolved in water, calculated as Na;
C) in total at least 1 wt. %, but in total no more than 10 wt. %, of water-insoluble oxide pigments, comprising oxide pigments of the element Ti and the element Al;
D) less than 10 mg/kg of phosphates, calculated as PO4;
E) a Total Organic Content of less than 10 g/kg, calculated as the amount of CO2;
obtainable by mixing one or more water glass solutions, each containing a silicate of the general empirical formula M2O·nSiO2, where n is a natural number of at least 2.5, but no greater than 4.5, and M is selected from sodium or potassium, with a corresponding amount of the water-insoluble oxide pigments.
