Abstract
(DE) Die Erfindung betrifft wäßrige Klarlacke, enthaltend eine mehrkomponentige wäßrige Dispersion, welche enthält: A) mindestens ein hydroxylgruppenhaltiges Bindemittel in wäßriger Dispersion und B) eine mit einem hydroxylgruppenhaltigen Emulgator hergestellte stabile wäßrige Dispersion eines hydrophoben Aminoplastharzes. Bevorzugt ist das hydrophobe Aminoplastharz in Komponente B) ein hydrophobes Melaminharz und das in der Komponente A) enthaltene hydroxylgruppenhaltige Bindemittel ein hydroxylgruppenhaltiges Polyacrylat. Weiterhin umfaßt von der Erfindung sind ein Verfahren zum Aufbringen mehrschichtiger Überzüge, in dem die erfindungsgemäßen wäßrigen Lacke als Decklack eingesetzt werden, sowie mit solchen mehrschichtigen Überzügen beschichtete Substrate.
(EN) The invention relates to aqueous transparent lacquers containing a multicomponent aqueous dispersion, composed of A) at least one binder containing a hydroxyl group in aqueous dispersion and B) a stable aqueous dispersion of a hydrophobic aminoplast resin produced with an emulsifier containing a hydroxyl group. The hydrophobic aminoplast resin in component B) is preferably a hydrophobic melamine resin. The binder containing a hydroxyl group in component A) is preferably a polyacrylate containing a hydroxyl group. The invention also relates to a method for applying multilayer coatings in which the inventive aqueous lacquers are used as a covering lacquer. The invention lastly relates to substrates coated with such multilayer coatings.
(FR) L'invention concerne des vernis aqueux contenant une dispersion aqueuse à plusieurs constituants qui contient A) au moins un liant contenant un groupe hydroxyle en dispersion aqueuse et B) une dispersion aqueuse stable d'une résine aminoplaste hydrophobe, dispersion produite avec un émulsifiant contenant un groupe hydroxyle. La résine aminoplaste hydrophobe dans le constituant B) est de préférence une résine de mélamine hydrophobe et le liant contenu dans le constituant A) et comportant un groupe hydroxyle est de préférence un polyacrylate contenant un groupe hydroxyle. L'invention concerne également un procédé pour l'application de revêtements multicouches, procédé dans lequel on utilise les vernis aqueux selon l'invention comme vernis de finition. L'invention concerne enfin les substrats enduits avec de tels revêtements multicouches.
