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: Methods for printing a conductive object are provided which may comprise dispensing one of a first ink composition and a second ink composition towards a substrate surface to form a deposition region on the substrate surface or on a previously printed object on the substrate surface, wherein the first ink composition comprises an aqueous solution of a metal compound and the second ink composition comprises an aqueous solution of a stable free radical; dispensing the other of the first and second ink compositions in the deposition region to mix the first and second ink compositions and induce chemical reduction of the metal compound by the stable free radical and precipitation of the metal of the metal compound; and removing solvent from the deposition region, thereby forming a conductive object comprising the precipitated metal.
