摘要：
The present invention is directed to aqueous stoving lacquers containing pigments or fillers wherein the binders are based on combinations of (a) polyurethane prepolymers containing partly or completely neutralized carboxyl groups and blocked isocyanate groups and (b) polyurethane prepolymers containing free hydroxyl groups and partly or completely neutralized carboxyl groups. The binder components are further characterized by polyester and polyether segments, each being present in amounts of greater than 10% by weight.The present invention is also directed to films and coatings prepared from these aqueous stoving lacquers.
