Abstract
The invention relates to aqueous clearcoats comprising a multicomponent aqueous dispersion which comprises: A) at least one aqueous dispersion of a hydroxyl-containing binder, and B) a stable aqueous dispersion of a hydrophobic amino resin, said dispersion being prepared using a hydroxyl-containing emulsifier. The hydrophobic amino resin in component B) is preferably a hydrophobic melamine resin and the hydroxyl-containing binder in component A) is preferably a hydroxyl-containing polyacrylate. Further embraced by the invention are a method of applying multilayer coatings, in which the aqueous coating materials of the invention are used as topcoat, and substrates coated with such multilayer coatings.
