摘要： An ink set which comprises a black ink containing an aqueous medium and a pigment dispersed in the aqueous medium by an action of an ionic group, and at least two color inks each containing a coloring material and an aqueous medium, wherein (i) respective images formed with the respective color inks have the same &Dgr;E or have the difference in &Dgr;E that is 10 or less in a CIELAB color space display system in a fading test under conditions that cause fading corresponding to pseudo-indoor sunlight fading through a window for 3 years or more, and (ii) at least one of the color inks contains at least one of a coloring material and an additive that destabilize dispersion stability of the pigment in the black ink. The ink set can provide a high quality multicolor image keeping color balance after long preservation and showing less bleeding between black and color regions.

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： 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： 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°.

摘要： An ink cartridge includes an ink-jet head and plural liquid chambers storing inks different from each other. The minimum value A1 (g/ml) for the ink densities of the inks stored in the plural liquid chambers and the maximum value B1 (g/ml) for the ink densities of inks each obtained by evaporating 10 mass % of each of the inks stored in the plural liquid chambers satisfy the relationship of (B1−A1)/A1≦0.100. A stable image can be obtained, in which, even when the ink cartridge is stored for a long time period at the time of physical distribution, or is stored for a long time period in a state of being mounted on a recording apparatus so that the stored inks are brought into a situation in which the inks are apt to evaporate, a change in color balance is small as compared to an initial state.
