    Abstract: A reaction solution to be used for image recording with an ink containing a coloring material in a dissolved or dispersed state in order to achieve a high level of image density with stability, wherein the reaction solution contains a polyvalent metal ion and an organic solvent to destabilize the dissolved or dispersed state of the coloring material in the ink in contact with the ink, has a pH of 2 or higher, and has a buffering action for pH, wherein the buffering action means it can maintain pH variation within the range of 0.5 before and after the addition of 1.0 ml of a 0.1 N aqueous lithium hydroxide solution to 50 ml of the reaction solution.

    Abstract: The present invention provides a fluorescence ink having a high fluorescence intensity, and an ink jet recording method using the same. The ink contains a first fluorescent coloring material that emits fluorescence at a predetermined fluorescence wavelength to be used for measurement or determination with excitation at a predetermined excitation wavelength, a second fluorescent coloring material that emits fluorescence on excitation at the predetermined excitation wavelength, where the excitation spectrum of the first coloring material in the ink to obtain the fluorescence at the predetermined emission wavelength has a peak wavelength range next to the predetermined fluorescence wavelength, and the emission fluorescence spectrum of the second coloring material has an emission wavelength region substantially including at least the above peak wavelength range.

    Abstract: Disclosed herein is an ink-jet printing process comprising the three steps of (a) applying inks containing a disperse dye, a compound for dispersing the disperse dye and an aqueous medium to a cloth comprising fibers dyeable with disperse dyes according to an ink-jet system (b) subjecting the cloth, to which the inks have been applied, to a heat treatment and (c) cleaning the heat-treated cloth, wherein the inks comprise two or more inks which separately contain disperse dyes of the same hue and are different in dye concentration, and the thermal diffusivity of the disperse dye used in the ink having a low dye concentration is higher than that of the disperse dye used in the ink having a high dye concentration.
