<p>PCT No. PCT/EP90/02256 Sec. 371 Date Jul. 21, 1992 Sec. 102(e) Date Jul. 21, 1992 PCT Filed Dec. 12, 1990 PCT Pub. No. WO91/09686 PCT Pub. Date Jul. 11, 1991.The present invention relates to a process in which 1. a water-dilutable basecoat composition is applied which contains at least one water-dilutable binder, metallic pigments, if desired color pigments, if desired conventional auxiliaries and additives and up to 20% by weight of organic solvents, 2. a polymer film is formed from this basecoat composition, 3. a transparent topcoat containing a polymer containing silyl groups and obtainable by copolymerization of p1 p1) 0.1 to 40% by weight of ethylenically unsaturated silane monomers of the general formula (* CHEMICAL STRUCTURE *) where R1 is alkyl, aryl, acyl, aralkyl having 1 to 10 carbon atoms R2 is an organic radical having a polymerizable double bond X is a hydrolyzable group n is 1, 2 or 3 p2) 5 to 30 % by weight, preferably 8 to 25% by weight, of monomers having at least 2 polymerizable ethylenically unsaturated double bonds and p3) 30 to 90% by weight of ethylenically unsaturated monomers without groups having active hydrogen, is applied to this base layer 4. and the top layer is cured together with the base layer.</p> |
