ABSTRACT:
An ink set for ink-jet recording includes two or more inks each of which contains water, a coloring agent, and a water-soluble organic solvent. The ink set is prepared so that a ratio (Vmin/Vmax) between a maximum permeation velocity Vmax of the ink and a minimum permeation velocity Vmin of the ink is not less than 0.6 when the respective inks are developed by means of paper chromatography on a certain paper. It is possible to suppress the bleeding of a formed image.
