Abstract:
1. Aqueous preparations having soft-feel properties and comprising A) aqueous polyurethane-polyurea dispersions, B) hydroxy-functional, aqueous or water-dilutable binders, C) polyisocyanates, which may have been hydrophilically modified, and D) foam stabilizers; wherein component A) is prepared from: a1) a combination of polytetramethylene glycols and polycarbonate polyols having number average molecular weights of at least 300, containing at least two free hydroxyl groups and which are capable of reaction with isocyanate groups, a2) optionally, diols of the number average molecular weight range 62 to 299, a3) optionally, nonionic hydrophilicizer based on a copolymer of ethylene oxide and propylene oxide, a4) one or more di- or polyisocyanates, a5) one or more aliphatic and/or alicyclic primary and/or secondary polyamines, and a6) one or more isocyanate-reactive, ionically or potentially ionically hydrophilicizing compounds.
