  • Radiation curable phase change inks containing curable epoxy-polyamide composite gellants
    Patent number: 7563489
    Abstract: A radiation curable phase change ink preferably used in piezoelectric ink jet devices includes an ink vehicle that includes at least one curable epoxy-polyamide gellant, and at least one colorant. The use of the gellant enables the ink to form a gel state having a viscosity of at least 103 mPa·s at very low temperatures of about 25° C. to about 100° C. The ink may thus be jetted, for example onto an intermediate transfer member surface or directly to an image receiving substrate, at very low jetting temperatures of, for example, about 40° C. to about 110° C.
