    摘要: PROBLEM TO BE SOLVED: To provide a phase change ink composition containing a synergist for pigment dispersion.SOLUTION: A phase change ink composition comprises: a pigment; a carrier; a dispersant; and a synergist, where (a) for a given sample of the synergist, about 80 to about 100% of the sample has a volume average particle diameter of about 50 to about 200 nm; (b) the synergist has a surface area of about 30 to about 100 m/g; and (c) the synergist has a density of about 0.6 to about 2 g/cm. The synergist is a mixture of a sulfone group-substituted copper phthalocyanine isomer mixture and ammonium ions having H or Calkyl groups.
