    Abstract: The invention relates to a method for producing chromophore and/or effect giving multilayer lacquers according to the wet-on-wet method. A water base lacquer is applied which contains at least one graft copolymer containing (A) at least one (meth)acrylate copolymer and (B) at least one polyurethane. The graft copolymer can be produced by (1) dispersing at least one hydrophilic or hydrophobic self cross-linking polyurethane (B) with a statistical average of at least one terminal and/or at least one lateral olefinically unsaturated group and at least one blocked isocyanate group per molecule in an aqueous medium. (2) A mixture of a at least one monomer (a1) with at least one isocyanate reactive functional group at last one monomer (a2) that can be copolymerised therewith is subsequently radically copolymerised in an emulsion in the presence of the polyurethane (B) or the polyurethanes (B).
