    摘要： An in situ process for preparing a phase change magnetic ink including heating a phase change ink composition to a first temperature sufficient to provide a melt composition; wherein the phase change ink composition comprises a carrier, an optional colorant, and an optional dispersant; placing the melt composition under inert atmosphere; heating the melt composition to a second temperature sufficient to effect decomposition of a metal carbonyl; adding the metal carbonyl to the melt composition under inert atmosphere at this second temperature to form metal nanoparticles thus forming in situ a phase change magnetic ink including the metal nanoparticles; optionally, filtering the phase change magnetic ink while in a liquid state; and cooling the phase change magnetic ink to a solid state.

    摘要： An ink set including at least two inks. A first ink includes an optional colorant, a first multi-functional monomer, a second multi-functional monomer that is different from the first multi-functional monomer, and a peroxide initiator comprising a thermal free radical initiator. A second ink includes an optional colorant, a first multi-functional monomer, a second multi-functional monomer that is different from the first multi-functional monomer, and an amine activator having a catalyst which catalyzes the homolytic cleavage of the thermal free-radical initiator at low temperatures into radicals. The first ink is free of the amine activator and the second ink is free of the peroxide initiator. The first multi-functional monomer and the second multi-functional monomer accelerate reaction kinetics through a Trommsdorff effect. The components are each present in an amount relative to the other that provides a) early onset of gelation that accelerates polymerization, and b) an ink viscosity that is suitable for jetting from an ink jet printer.

    摘要： A process including disposing at least one phase separation ink in an imagewise fashion onto a final image receiving substrate to form an ink image, wherein disposing is at a first temperature at which the at least one phase separation ink is in a molten, unseparated state; cooling the ink image to a second temperature sufficient to initiate crystallization of at least one component of the at least one phase separation ink, wherein at the second temperature the at least one phase separation ink comprises a crystalline phase and an amorphous phase; wherein the amorphous phase of the at least one phase separation ink substantially penetrates into the final image receiving substrate; and wherein the crystalline phase of the at least one phase separation ink substantially remains on the surface of the final image receiving substrate; applying pressure to the ink image on the final image receiving substrate; and allowing the ink to complete crystallization.
