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.
