    摘要: A recording ink composition comprises pure water, a water-soluble dye, a polyvalent alcohol, and phosphoric acid. When iron is contained as an impurity in the recording ink composition, the iron and phosphoric acid form a ferric (III) phosphato complex ion represented by �Fe(HP0.sub.4)(H.sub.2 O)!.sup.+. Owing to the formation of the complex ion, the recording ink composition is prevented from discoloration which would be otherwise caused by iron ion. Further, the recording ink composition is prevented from formation and deposition of iron compounds. Therefore, the obtained ink has an excellent color tone, and the ink avoids blocking at a nozzle of a printing head or the like of an ink-jet printer.

    摘要: An inventive ink comprises a water-soluble dye or a pigment as a coloring agent, 5 to 15% by weight of polyvalent alcohol monoalkyl ether selected from the group consisting of tetraethylene glycol monoalkyl ethers and pentaethylene glycol monoalkyl ethers, 5 to 50% by weight of polyvalent alcohol, and pure water. When recording is performed in accordance with the ink-jet recording system by using the inventive ink, an excellent result is obtained from any viewpoint concerning, for example, the recording characteristic, the fixation to an objective recording material, the quick drying characteristic, the printing quality characteristic, and the low odor characteristic. The inventive ink is useful as an ink to be used for ink-jet recording apparatuses based on various recording systems, making it possible to obtain an excellent recording result.
