    摘要： A process for improving the intercoat adhesion in a multicoat paint system utilizing a primer coat, an aqueous basecoat, and a clearcoat, where the multicoat paint system has been produced by means of a wet-on-wet technique. The clearcoat is produced using a pseudoplastic powder clearcoat slurry prepared by a secondary dispersion process or a melt emulsification process. The aqueous basecoat material used to produce the aqueous basecoat comprises a dispersed graft copolymer whose particles are composed of a hydrophobic core of copolymerized olefinically unsaturated monomers and of a hydrophilic shell which comprises a polyurethane, wher said copolymer is prepared by free-radical (co)polymerization of the monomers in the presence of at least one polyurethane containing specially selected olefinically unsaturated groups.

    摘要： The invention relates to coating materials containing a water-dilutable polyurethane resin as binder. The resin can be prepared by reacting some of the free isocyanate groups present in a prepolymer (I) which contains acidic groups and isocyanate groups with a blocking agent so as to form a prepolymer (II) which contains blocked isocyanate groups, the blocking agent being employed in a quantity such that the prepolymer (II) still contains on average at least one free isocyanate group per molecule, reacting the prepolymer (II) with a compound which contains at least one primary or secondary amino group and at least one hydroxyl group in the molecule, to give a polyurethane resin, and finally converting the polyurethane resin prepared in this way into a water-dilutable polyurethane resin by at least partial neutralization of the acidic groups.
