    Abstract: 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.

    Abstract: Disclosed is a process for preparing a phase change ink composition which comprises (a) a phase change ink carrier, said carrier comprising at least one nonpolar component and at least one polar component, and (b) pigment particles, said process comprising (1) selecting at least one of the polar carrier components to be a pigment particle dispersant; (2) admixing the pigment particles with the dispersant; (3) extruding the mixture of pigment particles and dispersant in an extruder at a temperature that is at or above about the peak crystallization temperature of the dispersant and below about the peak melting temperature of the dispersant, thereby forming a pigment dispersion; (4) subsequent to extrusion of the pigment dispersion, adding to the pigment dispersion any remaining polar components and the nonpolar component; and (5) subjecting the resulting mixture of pigment dispersion, polar component, and nonpolar component to high shear mixing to form an ink.
