    Abstract: An ink set for ink-jet recording that comprises a plurality of inks containing coloring materials insoluble in water to form a high quality ink-jet recording image is provided. The water-based ink set for ink-jet recording comprises a black ink and a color ink, wherein the black ink contains a carbon black as a coloring material having a volume average particle diameter determined by dynamic light scattering of not less than 50 nm, the color ink contains a pigment as a coloring material having a volume average particle diameter determined by dynamic light scattering of not more than 60 nm, and an accumulative 90% particle diameter of volume particle size distribution of not more than 100 nm, the volume average particle diameter of the carbon black of the black ink is larger than the volume average particle diameter of the pigment of the color ink, and the black ink has a surface tension higher than that of the color ink.

    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: 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.

    Abstract: Disclosed herein is a liquid discharging method, comprising using a liquid-discharge head equipped with a discharge opening from which a liquid is discharged, a first region to which a first liquid is supplied, a bubble-generating region containing a second liquid and generating bubbles in the second liquid, and a movable member which is displaceable between a first position opposite to the bubble-generating region and a second position within the first region and apart from the bubble-generating region and has a support part more upstream than its free end, in which the movable member is displaced from the first position toward the second position with the generation of a bubble in the bubble-generating region, and the bubble is guided to the discharge opening by the movable member, wherein the first liquid and the second liquid have no compatibility with each other.
