The first fluorescent dye has a first ultraviolet absorption wavelength region in an absorption spectrum and a first fluorescence emission wavelength region in a fluorescence spectrum. The second fluorescent dye has a second ultraviolet absorption wavelength region which is different from the first ultraviolet absorption wavelength region in an absorption spectrum and a second fluorescence emission wavelength region in a fluorescence spectrum. The first fluorescent dye further has an absorption wavelength region which is different from the first ultraviolet absorption wavelength region and which overlaps at least a part of the second fluorescence emission wavelength region.

摘要： A fluorescent water base ink for ink-jet recording includes water, a first fluorescent dye, and a second fluorescent dye. The first fluorescent dye absorbs light in a first absorption wavelength region in an ultraviolet region to emit fluorescence, and the first fluorescent dye absorbs light in a second absorption wavelength region to emit no fluorescence. The second fluorescent dye absorbs light in an absorption wavelength region in the ultraviolet region, which is different from the first absorption wavelength region of the first fluorescent dye, to emit fluorescence. A wavelength region of the fluorescence of the second fluorescent dye is not overlapped with the first absorption wavelength region of the first fluorescent dye, but at least a part of the wavelength region of the fluorescence of the second fluorescent dye is overlapped with the second absorption wavelength region. The fluorescence intensity of the ink is increased.

摘要： Fluorescent water base ink for ink-jet recording contains water, a fluorescent dye having a skeleton for emitting fluorescence, and a polyol having not less than two hydroxyl groups. A distance between oxygen and oxygen of the two hydroxyl groups in the polyol is substantially equal to or longer than a length of the skeleton of the fluorescent dye. When the fluorescent dye has a xanthene skeleton, 1,5-pentanediol can be used as the polyol. The ink has the high fluorescence intensity.

摘要： A water base ink for ink-jet recording, which is usable for an ink-jet recording apparatus having an ink-jet head provided therein with an ink flow passage formed of nickel or nickel alloy, includes a coloring agent, water, and a water-soluble organic solvent. The ink is blended so that a current density, which is obtained within an electric potential range of −600 to +300 mV, is not more than 100 &mgr;A/cm2 when anodic polarization measurement is performed by using a reference electrode of silver/silver chloride, a counter electrode of platinum, and a working electrode of nickel or nickel alloy. The ink does not corrode any part for constituting the flow passage in the ink-jet head.

摘要： An ink-jet water-based ink set comprises a black ink and a yellow ink. The black ink contains a black dye, barium hydroxide, and purified water. The yellow ink contains a yellow dye, ammonium chloride, and purified water. When these inks are used to produce liquid drops and to record images on a recording medium with the aid of an on-demand recording head, the barium hydroxide and ammonium chloride initiate an endothermic reaction, whereby color intermixing is reduced, and adequate spraying stability is obtained.
