| 摘要 |
<p>The invention relates to an aqueous coating composition comprising a dispersion of an acrylic copolymer A, a crosslinker B which is a multifunctional isocyanate B1, or an aminoplast crosslinker B2 or a combination of both Bl and B2, and water, wherein the acrylic copolymer A has moieties derived from alkyl(meth)acrylates A1, from hydroxyalkyl(meth)acrylates A2, from olefinically unsaturated carboxylic acids A3, and optionally, further olefinically unsaturated monomers A4 selected from the group consisting of vinyl aromatics A41, vinyl esters A42, vinyl halogenides A43, olefinically unsaturated amides A44, olefins A45, vinyl ester A46, and from an olefinically unsaturated surface-active compound A5 which has at least one olefinic unsaturation, and at least one hydrophilic group per molecule, a method for its preparation, and the use thereof in coating metal substrates, stone, concrete, paper and cardboard.</p> |
