摘要： An ink-jet water-based ink set comprises a black ink and a yellow ink. The black ink contains a black dye, barium hydroxide, and purified water. The yellow ink contains a yellow dye, ammonium chloride, and purified water. When these inks are used to produce liquid drops and to record images on a recording medium with the aid of an on-demand recording head, the barium hydroxide and ammonium chloride initiate an endothermic reaction, whereby color intermixing is reduced, and adequate spraying stability is obtained.

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.

摘要： An ink for ink-recording is provided, which makes it possible to reduce color bleed while suppressing even when recording is performed on regular paper. The ink for ink-jet recording contains water, a coloring agent, a water-soluble organic solvent, and a compound represented by the following general formula (1): wherein R represents a alkyl group having a number of carbons of 8 to 18, and x+y is not more than 10. A surface tension of the ink is controlled to 31 to 35 mN/m, which can reduce color bleed and feathering.
