Reinforced coatings with improved scratch resistance

摘要

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 R₁ is C₁-C₈alkyl, C₅-C₈cycloalkyl, phenyl or C₁-C₄alkyl substituted phenyl; R₂ is C₁-C₈salkyl, and n is 0, 1, 2 or 3; with a base. These coatings for protecting surfaces are reinforced and show improved scratch resistance.
