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： An ink set for ink-jet recording of the present invention includes a black ink which has a surface tension of not less than 40 mN/m at 25° C., and a color ink which has a surface tension of not less than 40 mN/m at 25° C. The viscosity ratio of the color ink with respect to the black ink is not less than 1.3. The feathering of the ink is avoided, and the bleeding, which would otherwise appear at the boundary between the black ink and the color ink, is avoided.

摘要： In a water base ink set for ink-jet recording including a pigment-based black ink and a dye-based yellow ink, a first water-soluble dye in which a number of counter ion or ions per one molecule is not more than 3 and a hue angle h* is 95° to 105° is used, as the dye used in the yellow ink, together with a second water-soluble dye in which a number of counter ion or ions per one molecule is not more than 3 and a hue angle h* is 75° to 85°; or 30° to 70°; or 0° to 30° or 350° to 360°. When the ink set is applied to a general ink-jet printer with a simple maintenance system, the coagulation of black pigment in the printer and the blurring or bleeding on the printing paper are prevented, thereby realizing a satisfactory and complex coloring of the dye-based yellow ink.

摘要： A water base ink for ink-jet recording comprises water, a coloring agent, a water-soluble organic solvent, and a benzotriazole-based metal-inactivating agent and alkanolamine. When the ink is used in an ink-jet recording apparatus which has the metal member containing nickel or nickel alloy in an ink supply passage, nickel is eluted from the metal member in an amount of not more than 50 ppm. The ink makes it possible to perform stable jetting operation for a long term without causing any deterioration of metal members of a discharge head due to the metallic corrosion and the elution of nickel into the ink.
