Abstract

The invention provides aqueous preparations having soft-feel properties, foams obtainable by mechanically foaming these preparations, and soft-feel coatings based on the foams. The preparations comprise aqueous polyurethane-polyurea dispersions, hydroxy-functional, aqueous or water-dilutable binders, polyisocyanates which may have been hydrophilically modified, and foam stabilizers.
