Urethane isocyanate-derived resins for use in a phase change ink formulation

摘要

Urethane resins are made by reacting selected nucleophiles, including alcohols, with an isocyanate. The order of addition of the isocyanate and the different nucleophiles can tailor the distribution of mixed urethane molecules in the final resin product. The final resin product can be colored or uncolored. The isocyanate-derived resin materials are useful as ingredients as phase change ink carrier compositions used to make phase change ink jet inks.
