The present invention comprises the following steps: Applying a color and / or special effect base coat and a clear clear coat top coat layer or a colored single layer top coat top coat layer over the previously applied coating; II. Optionally, applying a sealing layer of a transparent sealing coat over the topcoat layer applied in Step I, III. A method for producing a scratch-resistant automotive coating comprising the steps of curing the topcoat layer applied in step I and optionally the sealing layer applied in step II. Single layer topcoat and / or transparent sealing coat contains modified nanoparticles based on element-oxygen network, elements such as aluminum, silicon, tin, boron, germanium, gallium, lead, and lanthanides and actinides Wherein the modified nanoparticles are selected from the group of the general formula (I) Me (OR 1 ) 4 and / or the general formula (II) Me (OCOR 1 ) 4 It is prepared by treating a compound, in the above formula, R 1 meaning alkyl, aryl and / or aralkyl residues , Me means zirconium and / or titanium. |
