Aqueous dispersions of hydrophilic polyurethane resins
Abstract:
An aqueous polyurethane resin dispersions containing i) a polyol component with a molecular weight above 300 daltons, containing a polyether diol initiated on an aromatic diol, ii) a polyol component with a molecular weight of 62 to 299 daltons, iii) a monofunctional isocyanate-reactive compound with an ethylene oxide content of at least 50 wt. % and a molecular weight of at least 400 daltons, iv) a polyisocyanate v) an aliphatic polyamine with a molecular weight of 60 to 300 daltons or hydrazine, and vi) a hydrophilic aliphatic diamine, a process for making the dispersion and substrates primed with the dispersion.
