ABSTRACT:
An ink jet recording ink comprising water, a coloring material such as carbon black, (a) a dispersant containing at least one of a sulfonic acid group, sulfuric ester, and salt thereof, such as a polystyrenesulfonate polymer, and (b) a dispersant above-mentioned dispersants is preferably from 0.1 to 20 parts by weight based on 10 parts by weight of the coloring material. Further, the pH, surface tension, and viscosity of the ink are preferably from 7.0 to 10.0, from 30 to 65 mN/m, and from 1.0 to 10.0 mPa.multidot.s, respectively. Dispersion stability for a long period of time is improved, kogation in the thermal ink jet method is prevented, and excellent fixation on paper is obtained containing a carboxyl group or salt thereof, such as a styrene-maleate polymer, wherein the ratio by weight of (a) to (b) is from 1:5 to 1:100.
