Abstract: Disclosed is an aqueous ink containing water, a water-insoluble colorant and a plurality of water-soluble organic solvents. The water-soluble organic solvents contain a good solvent and poor solvent for the water-insoluble colorant in a specific ratio, and the water-soluble solvent having the largest Ka value among the water-soluble organic solvents is a poor solvent. When such an aqueous ink is in contact with a specific reactive liquid, the dissolution state or dispersion state of the water-insoluble colorant in the ink is destabilized, thereby having a sufficiently large area factor even with a small amount of ink droplet and enabling to obtain an image which is excellent in the image density, bleed resistance and fixability. This aqueous ink is also excellent in shelf life stability.

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.
