ABSTRACT:
Urethane resins are made by reacting selected nucleophiles, such as alcohols including a hydroxyl containing toughening agent, with an isocyanate. A colored urethane resin is combined to form a phase change ink. The order of addition of the isocyanate and the different nucleophiles can tailor the distribution of di-urethane and mixed urethane/urea molecules in the final resin product. The isocyanate-derived resin materials are useful as ingredients as phase change ink carrier compositions used to make phase change ink jet inks.
