ABSTRACT:
An ink set for ink-jet recording includes a first ink which contains glycerol and a first coloring agent, and a second ink which contains a water-soluble organic solvent incompatible with glycerol and a second coloring agent and which does not contain glycerol. The first ink and the second ink are mixed with each other at a low speed. Therefore, the inks permeate into the paper before the inks are mixed with each other. Thus, it is possible to avoid the color bleeding.
