Abstract
The invention relates to a sol-gel coating material, containing (A) an acrylate copolymer solution, consisting of at least one acrylate copolymer (A1), (B) a sol which can be produced by the hydrolysis, condensation and complexing of at least one hydrolysable metal compound (B1) of the dormula (1): MR ; wherein the variable and the index have the following meanings: M=aluminium, titanium or zirconium; R=hydrolysable group, hydroxy groups and non-hydrolysable groups, with the proviso that there should be at least one, preferable two hydrolysable groups; and n=3 or 4; by the hydrolysis, condensation and complexing of at least one hydrolysable silane (B2) of the formula (II): Si(R ) (R ) ; wherein the varible R and R have the following meanings: R =alkyl and/or cycloalkyl radicals and R =alkoxy and/or cycloakoxy radicals; and by the hydrolysis, condensation and complexing of at least one hydrollysable silane (B3) of the formula (III): SiR ; wherein the variable R has the aforementioned given meaning: with the proviso that the silane (B3) is not a silane (B2) according to the general formula (II); and (C) between 0 and 40% by weight in relation to the total quantity of the coating material, of a parent lacquer which can be produced by the hydrolysis and condensation of least one hydrolysable silane (B3) of general formula (III).
