    摘要： An ink-jet ink comprises water, a water-soluble coloring material having a molecular weight of 600 or less as a free acid form, at least two kinds of water-soluble organic solvents, and urea or a derivative thereof. The vapor pressures at 25° C. of the at least two kinds of water-soluble organic solvents are lower than that of water. The water-soluble organic solvents include a water-soluble organic solvent A and a water-soluble organic solvent B. The solubility of the water-soluble coloring material in the water-soluble organic solvent A is higher than its solubility in water, while its solubility in the water-soluble organic solvent B is equal to or lower than its solubility in water. The difference between the solubilities of the water-soluble coloring material in the water-soluble organic solvent A and in the water-soluble organic solvent B is 10% or more. The ink-jet ink does not cause clogging of an ejection portion nor deposition of a coloring material and is capable of providing good print quality even after leaving a printed image for a long term under high temperature and humidity conditions.

    摘要： A color ink jet recording method/apparatus is capable of reducing blurring of ink dots without reducing dot saturation, generating no difference in tones of secondary colors, and inviting no reduction of throughput, hence materializing an excellent performance of recording in high quality at high speed. A color image is formed by causing ink dots of plural colors to land in such a manner that each of the ink dots is essentially not superposed. The ink dots have the optical density of 1 or more and 1.5 or less. Thereby, overlapping between adjacent ink dots is lessened, and thus a high-quality color image having no difference in tones of secondary colors and a high saturation can be attained.

    摘要翻译： 彩色喷墨记录方法/装置能够减少墨点的模糊，而不会降低点饱和度，不产生二次色调的差异，并且不会降低生产量，因此以高速实现高质量记录的优异性能 。 通过使多个颜色的墨点以使得每个墨点基本上不重叠的方式落地来形成彩色图像。 墨点的光密度为1以上且1.5以下。 由此，可以减少相邻墨点之间的重叠，从而可以获得没有二次色调和高饱和度的高质量彩色图像。

    摘要： An ink cartridge for storing ink includes a thermal ink-jet head provided with a heating portion that generates thermal energy for discharging the ink. The heating portion has, on its surface in contact with the ink, a protective layer containing at least one of a silicon oxide, a silicon nitride, and a silicon carbide. The ink contains a substance that dissolves the protective layer and a compound represented by the following formula (1), and the content X (% by mass) of the compound of the formula (1) satisfies a relationship of 1≦X≦30: Formula (1) R1-A-R2, wherein A represents one selected from —S—, —S(═O)—, and —S(═O)2—, and R1 and R2 each independently represent a group selected from a hydrogen atom, a hydroxyl group, an alkyl group, a hydroxyalkyl group, an alkenyl group, an acyl group, a carbamoyl group, a carboxyl group, and a sulfonyl group.
