Abstract

Abstract Resins and waxes made by reacting selected nucleophiles, including alcohols and/or amines, with an isocyanate are disclosed. The order of addition of the isocyanate and the different nucleophiles can tailor the distribution of di-urethane, mixed urethane/urea, and/or di-urea molecules in the final resin product. The isocyanate-derived resin and wax materials are useful as ingredients as phase change ink carrier compositions used to make phase change ink jet inks.
