    Abstract: Solvent-free aqueous polyurethane-polyacrylate hybrid dispersions, a process for preparing them and their use for producing elastic coatings. The polyurethane-polyacrylate hybrid dispersions are obtained by preparing a hydrophilic or hydrophilicizable polyurethane by reacting isocyanate components with an equimolar amount of one or more diols or polyols, low molecular weight diols or polyols, and hydrophilic compounds having at least one NCO-reactive group, in the presence of ethylenically unsaturated monomers which are inert towards NCO groups. The resulting NCO-free polyurethane is dispersed in emulsion-polymerizing monomers.
