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.

US Classification:

524590

Abstract:

Phase change ink additives are disclosed which comprise quaternary ammonium salts that are extremely useful in producing phase change inks with increased specific conductance. Suitable and adjustable specific conductance is necessary for reliable functioning of electronic type ink level sensing systems used in phase change ink jet printers. Phase change inks may also be encoded for type by virtue of their specific conductance.
