The instant invention discloses a coating composition comprising a) an organic film-forming binder, and b) an inorganic additive of small particle size dispersed in an aqueous or alcoholic solvent prepared by a process which comprises the hydrolysis of a metal alcoholate or a compound of the formula (I) in which R<SUB>1 </SUB>is C<SUB>1</SUB>-C<SUB>8</SUB>alkyl, C<SUB>5</SUB>-C<SUB>8</SUB>cycloalkyl, phenyl or C<SUB>1</SUB>-C<SUB>4</SUB>alkyl substituted phenyl; R<SUB>2 </SUB>is C<SUB>1</SUB>-C<SUB>8</SUB>salkyl, and n is 0, 1, 2 or 3; with a base. These coatings for protecting surfaces are reinforced and show improved scratch resistance. |
