Abstract: An ecologically acceptable process is provided for the production of a chip resistant coating finishes by application of a chip resistant intermediate coating layer said coating comprising an aqueous based composition containing from 30 to 60% by weight carboxyl-containing polyesters or (meth)acrylates and copolymers thereof with vinyl compounds having an average acid value of 30 to 100 mg KOH/g and an average OH value of 50 to 250 mg KOH/g, neutralized with nitrogen bases, 5 to 25% by weight of a water-soluble or water-dispersible, blocked isocyanate prepolymer, 15 to 30% by weight water and @0 to 50% by weight pigments, fillers and/or auxililaries and additives, wet-in-wet overcoating with an aqueous filler, common stoving and painting with an aqueous based finishing paint.The chip resistant coatings are aqueous (water) based and essentially free of ecologically contaminating volatile organic solvents.
