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 set for ink-jet recording comprises a yellow ink, a magenta ink, and a cyan ink. Changes of colors &Dgr;EY, &Dgr;EM, &Dgr;EC of the yellow ink, the magenta ink, and the cyan ink satisfy the following relationship when the yellow ink, the magenta ink, and the cyan ink are deposited on regular paper, followed by being irradiated with light having a wavelength of 300 nm to 400 nm and an illuminance of 100 W/m2 for 30 hours by using a xenon lamp: |&Dgr;EY−&Dgr;EM|≦5, |&Dgr;EM−&Dgr;EC|≦5, |&Dgr;EC−&Dgr;EY|≦5. The ink set is excellent in color balance after the fading.
