    摘要: PROBLEM TO BE SOLVED: To provide an improved pigmented phase change ink composition, such as phase change ink having a pigment colorant stably and well dispersed in the ink. SOLUTION: The pigmented phase change ink composition includes an ink vehicle, a dispersant, and pigment particles. The dispersant is a compound represented by formula R 1 -CONH-R 2 -X. Wherein, R 1 is alkyl, aryl, alkylaryl, or arylalkyl having at least 23 carbon atoms; R 2 is alkylene, arylene, alkylarylene, or arylalkylene having at least 2 carbon atoms; and X is a quaternary ammonium salt. The ink has resistance to substantial aggregation and sedimentation of the pigment particles even when exposed to a freeze-drying cycle in the melt. COPYRIGHT: (C)2011,JPO&INPIT
