Coloring and/or effect-creating multilayer enamel coating, method for the production thereof and its use

   
   

A multicoat color and/or effect coating system ML for a primed or an unprimed substrate comprising--lying above one another--(1) a surfacer coat FL which absorbs mechanical energy, and (2) a color and/or effect topcoat DL, or (1) a surfacer coat FL which absorbs mechanical energy, (2) a color and/or effect basecoat BL, and (3) a clearcoat KL, or (1) a color and/or effect basecoat BL and (2) a clearcoat KL, wherein at least one coat, preferably at least two coats, and in particular all coats of the multicoat system ML has or have been produced from a coating material comprising at least one constituent (A) preparable by free-radical polymerization of a) olefinically unsaturated monomers and b) olefinically unsaturated monomers I different than the olefinically unsaturated monomers (a): R.sup.1 R.sup.2 C=CR.sup.3 R.sup.4 (I), in which the radicals R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each independently of one another are hydrogen atoms or alkyl, cycloalkyl, alkylcycloalkyl, cycloalkyalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the privso that at least two are aryl, arylalkyl or arylcycoalkyl radicals; in an aqueous medium.

Un sistema de capa ml del color y/o del efecto del multicoat para haber preparado o unprimed el substrato que abarcaba -- mintiendo sobre uno otro -- (1) una capa FL de la cepilladora que absorbe energía mecánica, y (2) un abrigo DL del color y/o del efecto, o (1) una capa FL de la cepilladora que absorbe energía mecánica, (2) un basecoat BL del color y/o del efecto, y (3) un clearcoat kilolitro, o (1) un basecoat BL del color y/o del efecto y (2) un clearcoat kilolitro, en donde por lo menos una capa, preferiblemente por lo menos dos capas, y en detalle todas las capas del sistema el ml del multicoat tiene o han sido producidas de un material de capa abarcando por lo menos un (a) constitutivo preparable por libre-radical la polimerización monomers no saturados y b) monomers olefinically no saturados I diferente que los monomers olefinically no saturados (a): R.sup.1 R.sup.2 C=CR.sup.3 R.sup.4 (i), en el cual los radicales R.sup.1, R.sup.2, R.sup.3 y R.sup.4 cada uno de uno otro son independientemente átomos del hidrógeno o radicales del alkyl, del cycloalkyl, del alkylcycloalkyl, del cycloalkyalkyl, del aryl, del alkylaryl, del cycloalkylaryl, del arylalkyl o del arylcycloalkyl, con los radicales del privso que por lo menos dos son aryl, del arylalkyl o del arylcycoalkyl; en un medio acuoso.
