    摘要: The phase change, curable composition comprises curable monomer, photoinitiator that initiates polymerization of the curable monomer, and phase change agent that provides the composition with an increase in viscosity of at least four orders of magnitude, from a first temperature, the first temperature being from 50° C. to 130° C., to a second temperature, the second temperature being from 0° C. to 70° C., wherein the second temperature is at least 10° C. below the first temperature. A coating over an image may be applied by providing a composition comprising curable monomer at a first temperature; applying the composition over the image, the image being at a second temperature; and exposing the composition to radiation to initiate polymerization of the curable monomer. In this process, the composition has a viscosity at the second temperature that is at least four orders of magnitude greater than its viscosity at the first temperature.

    摘要: 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.
