Abstract: 91/F 256 Curable binders obtained by simultaneous reaction of A) urethanes or ureas, B) acrylic or methacrylic compounds containing hydroxyl groups, C) paraformaldehyde and D) if appropriate, polyols, wherein, in the case where no polyol D) is also reacted, the reaction is carried out in the presence of an acid ion exchanger, and in the case where a polyol D) is also reacted, the reaction is carried out in the presence of an acid ion exchanger or a strong acid. These binders are suitable as coating compositions which can be cured by electron beams or by UV light.

Abstract: An aqueous coating composition which contains at least one water-dispersible polyurethane resin containing air-drying groups and optionally further binder resins and conventional (paint) additives, characterised in that the polyurethane resin contains units derived from (A) polyisocyanates, (B) polyols containing air-drying groups, optionally (C) polyols containing no air-drying groups, (D) compounds containing at least two groups which are reactive towards isocyanate groups and containing at least one group which is capable of forming anions, (E) monoalcohols containing air-drying groups, and/or (F) compounds which are different from (B), (C), (D) and (E) and contain at least one group which is reactive with NCO groups. This coating composition has excellent pigment compatibility, and the coatings produced therefrom provide good corrosion protection and have good mechanical properties, even without addition of a siccative.

Abstract: An aqueous coating composition for the manufacture of primers or of filler coatings, which contains at least one water-dispersible binder resin, as well as crosslinking agents and, if appropriate, customary additives, characterised in that the water-dispersible binder resin is at least partly a polyurethane resin which contains components which are derived from (A) polyisocyanates, (B) polyols having an average molecular weight Mn of at least 400, (C) if appropriate low molecular weight polyols, (D) compounds which contain at least two groups which are reactive with isocyanate groups and at least one group capable of anion formation, (E) polyols which carry no further groups reactive with isocyanate groups, where these components (E) are each located on the chain end of the polyurethane resin, if appropriate (F) compounds which are monofunctional or contain active hydrogen of differing reactivity and are different from (E), where these components (F) are also located on the chain end of the polyurethane resin and, if appropriate (G) compounds which are different from (B), (C), (D), (E) and (F) and contain at least two groups reactive with NCO groups. The filler coatings obtainable therefrom are distinguished, inter alia, by improved resistance to flying stones at low temperatures and by good intermediate layer adhesion, while corresponding primers show improved protection against corrosion.
