摘要

Disclosed is an ink set (A) wherein a plurality of aqueous inks (a) are combined to be used together with an aqueous ink (B) containing a water-insoluble coloring material. Each aqueous ink (a) constituting the ink set (A) contains one or more water-soluble organic solvents which are poor solvents for the water-insoluble coloring material of the aqueous ink (B), and the vapor pressure of at least one of the water-soluble organic solvents contained in each aqueous ink (a) at 20˚C is lower than the vapor pressure of water at 20˚C. When such an ink set is used for combining a plurality of aqueous inks so as to form a full color image wherein different color regions are adjacent to one another, the resulting image can be suppressed in color mixture (bleeding) at the boundaries between different color regions.
