Abstract
The invention relates to polyurethane-polyurea dispersions, also called PU
dispersion. which contain aralkylamine-blocked isocyanate groups, and to their preparation and use. This blocking agent ahs a significantly lower deblocking temperature as compared with the prior art. Coatings produced from this dispersion have high hydrolysis resistances. The arylamine-blocked isocyanate groups are composed of polyisocyanates, polymeric polyols having average molar weights of 400 to 6000, at least one blocking agent, and either or both of nonionically hydrophilicizing compounds or compounds having at least one ionic or potentially ionic group.
