Abstract: 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 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.

Abstract: A phase change ink composition comprising a phase change carrier composition, at least one compatible phase change magenta colorant material, and at least one organic sulfonic acid compound is disclosed. The sulfonic acid stabilizes the magenta dye.

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. Higher 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.

Abstract: Phase change carrier compositions made from the combination of at least one urethane resin; at least one urethane/urea resin; at least one mono-amide; and at least one polyethylene wax are disclosed. The order of addition of the reactants to form the reactant product urethane resin and urethane/urea resin permits the tailoring or design engineering of desired properties.

Abstract: Colored waxes are made by reacting selected nucleophiles, including alcohol containing colorants with an isocyanate are disclosed. A phase change ink is made by blending the colored wax with a clear ink carrier composition. The clear ink carrier composition can be a fatty amide-based material and/or a combination of isocyanate-derived resins in which 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 colored wax materials are useful as ingredients with phase change ink carrier compositions to make phase change ink jet inks.

Abstract: A phase change ink composition is disclosed wherein the ink composition utilizes polymeric dyes in combination with a selected phase change ink carrier composition.

Abstract: An aqueous phase change ink contains a water dispersible sulphonated polyester gloss agent and a selected concentration of hyperthermogelling component that causes the ink to gel when its temperature is increased to its thermo-inversion point or when the concentration of the hyperthermogelling component is increased by evaporation, or substrate absorption, of water from the ink. The ink may be jetted directly onto a heated and/or absorptive substrate or jetted onto a cooler and/or hydrophobic surface before being transferred to the substrate. The thermo-inversion point is preferably about ambient temperature, and the preferred hyperthermogelling component is a nonionic surfactant, such as an ethylene oxide propylene oxide block copolymer surfactant.
