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, where 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 a process for the production of a multicoat coating in which an aqueous transparent topcoat composition containing a polyacrylate resin as binder is employed. The polyacrylate resin can be obtained by adding, either successively or alternately in part amounts, a mixture of a carboxyl-containing ethylenically unsaturated monomer (a1) and a monomer (a2) free from carboxyl groups and a mixture (b) consisting of (meth)acrylic acid esters which are free from carboxyl groups, of hydroxyl-containing ethylenically unsaturated monomers and, if appropriate, of other ethylenically unsaturated monomers to an organic solvent and carrying out a polymerization in the presence of a radical-forming initiator and, at the end of the polymerization, neutralizing the resultant polyacrylate resin and dispersing it in water. The type and amount of (a1), (a2) and (b) are chosen so that the polyacrylate resin has a hydroxyl value of 40 to 200, an acid value of 20 to 100 and a glass transition temperature (T.sub.G) of -40.degree. C. to +60.degree. C.
