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:
A wax-tethered photoinitiator that is a photoinitiator compound including a wax chain therein, wherein the photoinitiator compound is activated by ultraviolet radiation, and method of making the same is described. The wax-tethered photoinitiator may be used in a curable wax composition for incorporation into a toner. The wax-tethered photoinitiator exhibits an affinity for the wax phase, thereby insuring its presence in the wax for the initiation of curing thereof.

摘要:
A method for forming toner particles includes polymerizing monomers to form a latex comprising polymer particles; combining the latex with unsaturated curable resin to form aggregates containing the polymer particles and the unsaturated curable resin particles; and heating the aggregates to form coalesced particles. A toner composition that may be formed by the process described herein contains toner particles containing polymer containing photoinitiator and unsaturated curable resin. Another toner composition that may be formed by the process described herein contains toner particles containing unsaturated curable resin and, on the surface of the toner particles, photoinitiator.
摘要:
An ink that may be used in ink jet devices is a photochromic ink comprising an ink vehicle that includes at least one radiation curable component, at least one photochromic material and at least one photoinitiator. The ink is cured via exposure to radiation that cures the at least one radiation curable component of the ink. A radiation curable ink capable of exhibiting photochromatic color changes, which may be used to indicate a document's authenticity, is thus achieved.
