    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： If an ink for a particular color (for example, red) having an excellent color developing characteristic is used in addition to inks for three primary colors of subtractive color mixture, the high color reproducibility is to be maintained for a long period. To accomplish this, at least one (for example, a yellow ink) of the inks of two colors between which the hue angle of red, included in the three primary colors, is sandwiched is applied to an area of a printing medium to which a red ink is applied so that the inks overlap each other. Thus, the yellow ink, having a high weatherability, is applied to an area on the printing medium to which only the red ink, having a low weatherability, is otherwise applied. It is therefore possible to improve the weatherability while maintaining the color developing characteristic at a high level.

    摘要翻译： 除了用于三基色减色混合物的油墨之外，如果使用具有优异显色特性的特定颜色（例如红色）的油墨，则可以长时间保持高色彩再现性。 为了实现这一点，将包含在三原色中的红色的色相角夹在其间的两种颜色的至少一种（例如，黄色油墨）施加到打印介质的区域， 施加红色墨水使得墨水彼此重叠。 因此，具有高耐候性的黄色油墨被施加到打印介质上仅具有低耐候性的红色油墨的区域。 因此，可以在将显色性保持在高水平的同时提高耐候性。

    摘要： Disclosed herein is an image-forming method, including performing image formation on the basis of pixel data by using at least a yellow recording agent, a magenta recording agent, and a third recording agent. A color represented on a recording medium by the third recording agent on a color space of CIE-L*a*b* has lightness higher than lightness of a color reproduction region represented on the recording medium by a combination of the yellow recording agent and the magenta recording agent, and has a hue angle in the color reproduction region. A difference in hue angle on the color space between a color represented by the yellow recording agent and a color represented by the magenta recording agent is in a range of 60 to 113°.
