Polyurethane dispersions prepared by polymerization, initiated by free radicals, of polyurethane macromonomers containing carboxyl, phosphonic acid or sulfonic acid groups and lateral vinyl groups and optionally terminal vinyl, hydroxyl, urethane, thiourethane and/or urea groups. These polyurethane dispersions are suitable for the production of coatings on substrates, as adhesives or as binders in printing inks.
