Abstract: An ink set, which is an ink set (A) obtained by combining a plurality of aqueous inks (a) and is used together with an aqueous ink (B) containing a water-insoluble color material, is characterized in that respective aqueous inks constituting the ink set (A) contain at least one kind of water-soluble organic solvent serving as a poor solvent for the water-insoluble color material constituting the aqueous ink (B), and among the water-soluble organic solvents which are respectively contained in the aqueous ink (a) and serve as a poor solvent, at least one kind of water-soluble organic solvent has a vapor pressure at 20°C lower than the vapor pressure of water at 20°C. It is possible to obtain an image in which occurrence of the bleeding at the boundaries between different color regions has been suppressed in the case where a full-color image in which the respective color-regions are situated adjacently to one another is formed.

Abstract: Disclosed is an aqueous ink comprising at least water, a plurality of water-soluble organic solvents and a coloring material. The coloring material is a pigment, and, it contains a pigment particle having at least one ionic group bonded to a surface of the pigment particle directly or via another atomic group. The plurality of water-soluble organic solvents have a good medium or good mediums for the pigment and a poor medium or poor mediums for the pigment. The poor medium does not solvate perfectly or substantially the pigment. The ionic group undergoes perfectly or substantially no ionic dissociation in the poor medium. Also, among the respective Ka values of the plurality of water-soluble organic solvents as determined by the Bristow method, the Ka value of the poor medium is maximum.

Abstract: An aqueous ink comprising at least water, a water-soluble organic solvent and a colorant. The colorant comprises a pigment containing a pigment particle having at least one ionic group bonded to a surface of the pigment particle directly or via another atomic group. The organic solvent undergoes completely or substantially no solvation with the pigment and the ionic group of the pigment particle undergoes completely or substantially no ion dissociation in the organic solvent.
