  • Patent number: 7459014
    Abstract: An ink preferably used in piezoelectric ink jet devices includes an ink vehicle that includes at least one curable monomer, at least one polymerizable organic gelator, at least one initiator, at least one colorant and optionally at least one low molecular mass non-reactive organic gelator and/or at least one thermal solvent. The use of the curable gelator enables the ink to form a gel state having a viscosity of at least 102.5 cps at very low temperatures of about 30° C. to about 50° C. The ink may thus be jetted at low temperatures of about 50° C. to about 90° C. The ink is heated to a first temperature above the gel point of the ink, jetted onto a surface maintained at a second temperature at which the ink forms a gel state, and when on the image receiving substrate, is exposed to radiation energy to polymerize the polymerizable components of the ink.

  • Patent number: 7384463
    Abstract: Phase change ink comprising an ink vehicle that includes at least one amphiphilic molecule. The amphiphilic molecule is capable of co-crystallizing into the at least one wax monomer to form functionalized spherulites which are then capable of hydrogen bonding to other similarly functionalized spherulites to form a bonded network of spherulites. Increased adhesive and cohesive strength of the ink on paper can result, thereby generating a robust image.
