To produce scratch-resistant coatings, a lacquer is obtained which has been obtained by hydrolytic polycondensation of at least one titanium compound, at least one organofunctional silane and, if appropriate, at least one inorganic oxide component, the amount of water used for the precondensation being entered by means of moisture-switching adsorbents, water-containing organic solvents or salt hydrates, onto a substrate and cures the coating obtained by heating. |
