摘要： A water base pigment ink for ink-jet recording contains a pigment, a propylene glycol derivative which has a saturation vapor pressure of 2 to 10 hPa and an octanol-water distribution coefficient log P of 0 to 1.35, and dipropylene glycol-n-propyl ether. The propylene glycol derivative is contained in the ink by 0.25 to 1.5% by weight, and the dipropylene glycol-n-propyl ether is contained in the ink by 0.5 to 1% by weight. The ink is excellent in the paper surface drying performance. Further, it is possible to avoid the occurrence of the feathering and the blank stripes in letters.

摘要： A water based ink set for ink-jet recording includes a yellow ink, a magenta ink, a cyan ink, a black ink, and a red ink and/or a blue ink each including at least a coloring agent, water and a water soluble organic solvent. In the water based ink set, a water soluble dye is employed as the coloring agent of each of the yellow ink, the magenta ink and the cyan ink, and a pigment is employed as the coloring agent of each of the black ink and the red ink and/or the blue ink. In an ink-jet recording method employing the water based ink set for ink-jet recording, the red ink and the magenta ink are employed together for a magenta-ink-recording portion, and the blue ink and the cyan ink are employed together for a cyan-ink-recording portion.

摘要： A water-based ink set for ink-jet recording is provided. According to this ink set, graininess in a low density printed part can be reduced without reducing a color reproduction range in red and magenta directions in a high density printed part. In addition, the color reproduction range in the red direction can be extended to improve the vividness of red color. The water-based ink set for ink-jet recording includes a magenta ink and a red ink. The magenta ink is a light magenta ink having a lightness (L*) of about 50 or more in the L*a*b* colorimetric system. Preferably, the ink set further includes a light cyan ink having a lightness (L*) of about 60 or more and a blue ink and/or a green ink.

摘要： A water based ink set for ink-jet recording, capable of reducing graininess, is composed of a combination of a diluting ink and one or more coloring inks. The diluting ink contains at least water and a water soluble organic agent and does not substantially contain a coloring agent, and the coloring ink contains at least a coloring agent, water and a water soluble organic solvent. In this ink set, the dynamic surface tension of the diluting ink is set to be higher than that of the coloring ink.
