    摘要: A water base pigment ink for ink-jet recording contains a pigment, water, and at least one of polyethylene glycol and diglycerol. The ink is solidified into a solid matter when the water is evaporated. Further, the solid matter is redissolved in the unsolidified water base pigment ink for ink-jet recording. When the ink is used, then neither clog-up of a nozzle nor discharge failure is caused, no load is imposed by the solidified ink on the maintenance system such as the wiping equipment, and the sticking performance on the paper is satisfactory.

    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 is provided, which makes it possible to secure a high recording quality with a sharp image area edge by avoiding any blurring even when recording is performed on regular paper and which has satisfactory purge restoration performance. Therefore, no bubble remains in an ink flow passage, and no discharge failure is caused. Further, the discharge operation never becomes unstable. In the water base ink for ink-jet recording, the surface tension is not less than 40 mN/m, and the amount of dissolved oxygen is not more than 4 mg/L.
