Abstract:
The present invention relates to urea-terminated polyurethanes dispersants based on diols and polyether diols, aqueous dispersions of such polyurethanes, the manufacture of the urea terminated polyurethane dispersions and inks containing pigments and/or disperse dyes dispersed with these urea terminated polyurethane dispersants. The urea termination can have nonionic hydrophilic substituents.
