    摘要： In an aqueous ink jet recording liquid including at least water, a water-soluble organic solvent and a water-insoluble coloring material, (1) the absolute value of the zeta potential is 20 mV or more, (2) the conductivity is from 0.05 to 0.75 S/m, (3) the number average particle size of dispersed particles is from 15 to 200 nm, and (4) the number of particles having a particle size of 0.5 &mgr;m or more present in one liter is 2.5×1011 or less. Due to the aforementioned, dispersion stability of the coloring material can be maintained in the ink jet recording liquid in which the water-insoluble coloring material is dispersed, and the aqueous ink jet recording liquid is provided, which is excellent regarding stability over long periods of time, causes no ink flow route clogging and prevents kogation in printing, provides a recorded material having excellent rub resistance, printing quality, optical density, water resistance and lightfastness, and can prevent uneven density.
