ABSTRACT:
A color and/or effect coating material which is free from rheological aids based on phyllosilicates and comprises(A) a water-soluble, water-dilutable and/or water-dispersible polyurethane;(B) a color and/or effect pigment;(C) a dispersing assistant selected from the group consisting of the reaction products of(c1) a functionalized copolymer containing(c11) a copolymerized olefinically unsaturated monomer isocyanate groups, anhydride groups and epoxy groups; and(c12) a copolymerized olefinically unsaturated monomer which is free from isocyanate-, anhydride- and epoxy-reactive functional groups;(c2) at least one homopolymeric polyalkylene glycol, and(c3) at least one compound of the general formula I:in-line-formulae description="In-line Formulae" end="lead"?NR2—C(O)—NR2 (I)in-line-formulae description="In-line Formulae" end="tail"?in which the variables R are selected from the group consisting of hydrogen atoms and organic radicals, at least one of the radicals R containing at least one reactive functional group selected from the group consisting of isocyanate-, anhydride- and epoxy-reactive groups; and(D) a rheological aid based on (meth)acrylate copolymers;and its use to produce single-coat and multicoat color and/or effect paint systems.
