<p>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 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.</p> |
