摘要： A water-based ink for ink-jet recording contains water, a water-soluble organic solvent, a coloring agent and a crown ether. Even when the water-based ink is employed in the ink passage of an ink-jet recording apparatus and comes into contact with rubber members employed in the ink passage, the occurrence of precipitation is prevented.

摘要翻译： 用于喷墨记录的水性油墨包含水，水溶性有机溶剂，着色剂和冠醚。 即使在喷墨记录装置的油墨通道中使用水性油墨并与油墨通道中使用的橡胶构件接触时，也防止了沉淀的发生。

摘要： A water base ink for ink-jet recording contains a self-dispersible coloring agent, a propylene glycol ether, and a surfactant represented by the following general formula (3): R1—O—(CH2CH2O)n—SO3M  (3) wherein R1 represents an alkyl group having a number of carbon atoms of 12 to 15, M represents Na or triethanolamine, and n represents an integer of 2 to 4, and wherein the propylene glycol ether is dipropylene glycol propyl ether. The ink satisfies three requirements of i) the satisfactory initial introduction performance of the ink into an ink flow passage of a stacked type printer head, ii) the prevention of the occurrence of feathering, and iii) the prevention of the insufficient spread of the ink.

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 contains 0.1% by weight to 4.0% by weight of C.I. Direct Yellow 132; not less than 0.5% by weight of glycol ether having a melting point of not more than −45°C.; and a water-soluble organic solvent in which a solubility of C.I. Direct Yellow 132 at 20° C. is not less than 5%. The ink satisfies 0.2≦B/A and 3≦C/A. B/A represents a weight ratio of the glycol ether to the C.I. Direct Yellow 132 contained in the ink, and C/A represents a weight ratio of the water-soluble organic solvent to the C.I. Direct Yellow 132 contained in the ink. The stability in long-term storage after the evaporation of water or at low temperatures can be obtained even when C.I. Direct Yellow 132 is used in the water-base ink for the ink-jet recording.
