Use of associative thickeners based on polyurethane and/or dipropylene glycol monoalkyl ethers in colored and/or decorative effect multi-layered lacquers

The invention concerns a novel aqueous composition that can be hardened physically, thermally and/or with actinic radiation, containing a compound of general formula (I): X&lsqb;NH&mdash;C(&boxH;O)&mdash;NH&mdash;Y&mdash;NH&mdash;C(&boxH;O)&mdash;OR&rsqb;2 having at least one urea and urethane group, wherein the variables have the following meaning: R represents identical or different polyalkylene glycol ether radicals; X represents a bivalent substituted or unsubstituted arylene radical; Y represents identical bivalent substituted or unsubstituted arylene radicals, which are the same as or different from radical X or different bivalent substituted or unsubstituted arylene radicals of which none or one is identical to radical X. The invention also concerns the utilization of said compound for the production of novel aqueous coating materials, adhesives and sealants that can be hardened physically, thermally or thermally and with actinic radiation and their derivatives.
