摘要:
A process for the preparation of a water-dissipatable polyurethane comprising preparation of a polyurethane prepolymer, reacting the polyurethane prepolymer with a mono functional end-capping agent to give a partially end capped polyurethane prepolymer and chain extending the partially end capped polyurethane prepolymer to give the water-dissipatable polyurethane. The polyurethanes are useful in ink jet printing.
