摘要： An ink set for ink-jet recording of the present invention includes a black ink which has a surface tension of not less than 40 mN/m at 25° C., and a color ink which has a surface tension of not less than 40 mN/m at 25° C. The viscosity ratio of the color ink with respect to the black ink is not less than 1.3. The feathering of the ink is avoided, and the bleeding, which would otherwise appear at the boundary between the black ink and the color ink, is avoided.

摘要： 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.
