    摘要： The present disclosure provides multicoat systems exhibiting ultraviolet (UV) stability after ultraviolet exposure and moisture exposure. The systems comprise at least one primer (G), at least one pigmented coating (P) disposed on a surface of the primer, and at least one ultraviolet (UV) absorber which has an absorption maximum of at least 370 nm. The pigmented coating (P) may be comprised of two or more coatings (P1), (P2) to (Pn). The multicoat systems may also comprise a transparent coating material (T) to form a transparent coating (K). The present multicoat systems demonstrate ultraviolet stability, reduced delamination of the pigmented coat from the primer and are available in a variety of shades for use in the finishing, refinishing and coating of component parts.The present disclosure also provides for a process for producing the multicoat system, and provides for the use of the system.

    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.
