An aqueous ink jet ink comprises water, a colorant selected from a dye or a pigment, and a diol derivative according to the following formula (Formula I):
HO-(CHX-CHYO)j-(CH2)a-G-(CH2)b-(OCHW-CHZ)k-OH (I)
wherein G is independently selected from the group consisting of SO2, SO, and CO; X, Y, W, and Z are independently selected from the group consisting of H, CH3 and CnH2n+1 where n equals 2 to about 20; j and k independently equal from 0 to about 100; and a and b independently equal from 1 to about 20. In addition, a multi-color ink jet printing process comprises (1) printing at least one of aqueous ink jet inks comprising the above diol derivative onto a print substrate at any desired sequence by a printhead in a single or multiple pass method according to digital data signals and (2) optionally applying heat to the print substrate and the imaged inks at any stage of said ink jet printing process including before, during, and after printing as well as combinations thereof.
水性喷墨墨水由水、选自染料或颜料的着色剂和符合下式(式 I)的二元醇衍生物组成:
HO-(CHX-CHYO)j-(CH2)a-G-(CH2)b-(OCHW-CHZ)k-OH (I)
其中 G 独立地选自 SO2、SO 和 CO 组成的组;X、Y、W 和 Z 独立地选自 H、CH3 和 CnH2n+1 组成的组,其中 n 等于 2 至约 20;j 和 k 独立地等于 0 至约 100;a 和 b 独立地等于 1 至约 20。此外,多色喷墨打印工艺包括:(1) 根据数字数据信号,通过喷头以单程或多程方法将包含上述二元醇衍生物的至少一种水性喷墨打印到打印基材上;(2) 在所述喷墨打印工艺的任何阶段(包括打印前、打印中和打印后以及其组合),对打印基材和成像油墨进行加热。
