摘要： An ink for ink-jet recording is provided, in which an amount of water X (% by weight) in the ink and a saturation viscosity Y satisfy Y≦4.5e0.09X. The saturation viscosity Y is a viscosity (mPa·s) obtained when an ink residual liquid, which is obtained by evaporating volatile components of the ink until a change in weight of the ink is less than 0.05 g/day per 50 g of ink under a condition of a temperature of 60° C. and a humidity of 40%, is cooled to a temperature of 25° C. in an environment of a humidity of 40%. X satisfies 50≦X≦75. The ink exhibits satisfactory jetting stability when the ink is normally used. Further, the ink is easily restored to give a normal jetting state even after undergoing an abnormal condition, for example, when the ink is left to stand without any nozzle cap.

摘要： A water base ink set for ink-jet recording comprises a first ink which contains an anionic dye, and a second ink which contains a cationic dye. At least one of the first and second inks contains at least two glycols selected from the group consisting of diethylene glycol, triethylene glycol, and polyethylene glycol, polyvinyl pyrrolidone, and water. The ink set makes it possible to stably discharge the ink by means of an ink-jet head, and it realizes vivid recording which is highly reliable and highly accurate and which provides good color balance.

摘要： A water-based ink for ink-jet recording and an ink-jet recording method allow the formation of sharp text and lines in high density black, and the formation of a high quality gradation image in which the graininess is reduced in a black image of a medium lightness to a high lightness (e.g., an achromatic image in dark gray to light gray) in ink-jet recording. The water-based ink combination for ink-jet recording comprises a black ink, and a color ink (A) and a color ink (B) that satisfy a color relationship of the following expression (I): about 120°≦|α-β|≦about 240°  (I) wherein α is the hue angle of the color ink (A) and β is the hue angle of the color ink (B).

摘要： A water base ink for ink-jet recording contains self-dispersible carbon black as a coloring agent. The total content of an organic acid having a number of carbon or carbons of 1 to 6 and a salt of the organic acid is not more than 400 ppm. The organic acid having a number of carbon or carbons of 1 to 6 includes monocarboxylic acid, dicarboxylic acid and oxy acid, and the salt of the organic acid includes salts of these acids. When the water base ink is used in an ink-jet recording apparatus, the discharge stability of the ink is improved.

摘要： A water base ink set for ink-jet recording includes a black ink containing water, a black pigment and a water-soluble organic solvent and a color ink containing water, a dye, and a water-soluble organic solvent. The black pigment is a negatively-chargeable and self-dispersible pigment. The dye has a fluorescein structure. The color ink further contains an alkylamine ethylene oxide adduct. The water-soluble organic solvent contained in the black ink is same as that contained in the color ink. With the ink set, not only the bleeding hardly occurs but also satisfactory discharge stability is obtained even when an ink-jet recording is performed on a regular paper.
