Abstract: A nanoscale pigment particle composition includes a quinacridone pigment including at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, wherein the functional moiety associates non--covalently with the functional group; and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized particles.

Abstract: A pigmented phase change ink composition comprising an ink vehicle, a dispersant, and pigment particles wherein the dispersant is a chemical compound of formula: (see above formula) wherein R1 is an alkyl group, aryl group, alkylaryl group or arylalkyl group with at least 23 carbon atoms, R2 is an alkylene group, arylene group, alkyarylene group or arylalkylene group with at least 2 carbons and X is a quaternary ammonium salt. The ink can be resistant to substantial aggregation and settling of the pigment particles in the melt and even when exposed to freeze thaw cycles.

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.
