Claim:
1. An aqueous composition having soft-feel properties and comprising: A) an aqueous polyurethane-polyurea dispersion wherein the polyurethane-polyurea consists of the following units: linear polyester diols or polyester polyols made from acids or anhydrides selected from the group consisting of adipic, decanedicarboxylic, terephthalic, isophthalic, o-phthalic, tetrahydrophthalic, hexahydrophthalic and acid anhydrides, and alcohols selected from the group consisting of ethanediol, di-, tri-, tetraethylene glycol, 1,2-propanediol, di-, tri-, tetrapropylene glycol, butane-1,4-diol, hexane-1,6-diol, 2,2-dimethyl-1,3-propanediol, 1,4-dimethylolcyclohexane and mixtures thereof, with or without the use of polyols of higher functionality; copolymers of hexane-1,6-diol, ε-caprolactone with diphenyl and/or dialkyl carbonates; and hydroxyl-containing polycarbonates prepared by reacting diols selected from the group consisting of 1,4-butanediol, 1,6-hexanediol, and mixtures thereof, with diaryl carbonates; B) a hydroxy-functional polyacrylate copolymer dispersion prepared from 2-ethyl hexyl acrylate, hydroxypropyl methacrylate, hydroxyethyl acrylate, butyl acrylate, butyl methacrylate, isobornyl methacrylate, styrene, methyl methacrylate, acrylic acid or mixtures thereof, and C) a polyisocyanate, which is optionally hydrophilically modified, wherein the copolymer dispersion B) further comprises a hydroxy-functional polycarbonate diol D) as a reactive diluent, wherein the composition has a haptic testing result of 1.
