Abstract: Water-emulsifiable polyisocyanates (I) comprise: (A) (cyclo)aliphatic or aromatic polyisocyanates; and (B) reaction prods. contg. at least one reactive NCO gp. and made by reacting (A) with polyvinyl pyrrolidones (PVP's). Pref. the PVP content of the (A)+(B) compsn. is 1-20 wt.%. The PVP, which esp. contains one or more NCO- reactive OH gps., is of Mn 400-40000. The (I)-contg. aq. dispersions are based on polyurethanes or radically-polymerised polymers.
