Phase change ink composition and process for preparing same

A process for preparing a phase change ink including (a) subjecting a white colorant to acoustic mixing at an acceleration of from about 30 to about 110 g; (b) optionally, adding a dispersant and subjecting the white colorant and dispersant to further acoustic mixing at an acceleration of from about...

Beschreibung
Zusammenfassung:	A process for preparing a phase change ink including (a) subjecting a white colorant to acoustic mixing at an acceleration of from about 30 to about 110 g; (b) optionally, adding a dispersant and subjecting the white colorant and dispersant to further acoustic mixing at an acceleration of from about 30 to about 110 g; (c) separately melt mixing an optional antioxidant, an optional synergist, and a phase change ink carrier comprising (i) a branched triamide and (ii) a polyethylene wax, a Fischer Tropsch wax, or a mixture or combination thereof, to form a melt mixture; (d) adding the melt mixture of (c) to the acoustically mixed white colorant of (a) or (b) with stirring; (e) optionally, adding a fluorescent dye with stirring; and (d) optionally, filtering the phase change ink.
