An ink composition which comprises (a) a colorant, and (b) a liquid vehicle which comprises (i) water, and (ii) a fluorinated material of the formula (F.sub.3 C(F.sub.2 C).sub.n CH.dbd.CHCH.sub.2 OCH(OH)CH.sub.2).sub.2 NCH.sub.2 COO.sup.- !X.sup.+ !, wherein X is a cation and n is an integer of from about 3 to about 20.
A process for preparing an ink composition which comprises (i) subjecting a composition comprising a material of the formula (F.sub.3 C(F.sub.2 C).sub.n CH.dbd.CHCH.sub.2 OCH(OH)CH.sub.2).sub.2 NCH.sub.2 COO.sup.- !X.sup.+ !, wherein X is a cation and n is an integer of from about 3 to about 20 to ultrasonification;
- and (ii) admixing colorant with the composition, thereby forming an ink, said ink composition further containing water.
