An ink jet ink composition for textile printing including a dye containing copper or chromium and 5% to 30% by mass of a cyclic amide that is liquid at normal temperature and that has a normal boiling point in the range of 190° C. to 260° C., wherein the hue angle ∠h° defined by the CIELAB color space on a recording medium ranges from 260 to 310 degrees.

A dye printing method and an ink capable of performing printing on more types of media than in the related art are shown. A dye printing method using ink 10 containing a solvent 11, and particles of a thermoplastic resin dispersed in the solvent 11 and containing a dye 13 is characterized by including a printing process of performing a printing on a medium 20 with the ink 10, a particle fixing process of fixing the particles 12 to the medium 20 by drying the solvent 11 of the ink 10 ejected to the medium 20 by the printing process, and a resin fixing process of fixing the thermoplastic resin to the medium 20 by heating the particles 12 fixed to the medium 20 by the particle fixing process, at least at a glass-transition temperature or higher.

A printing ink having a first fluorescent dye acting as donor and a second fluorescent dye acting as acceptor. The first fluorescent dye, upon excitation by electromagnetic radiation falling within an excitation wavelength range λ.sub.1a of the first fluorescent dye, is capable of emitting electromagnetic radiation in at least one first emission wavelength range λ.sub.1e, said first emission wavelength range λ.sub.1e of the first fluorescent dye overlapping with at least one excitation wavelength range λ.sub.2a of the second fluorescent dye, to thereby excite the second fluorescent dye to emit electromagnetic radiation in a second emission wavelength range λ.sub.2e.

The present invention relates to an inkjet ink comprising a photo-chromic colorant and a UV absorber. The ink may be used as a time-temperature indicator and is particularly useful in packaging food and/or drink to provide an indication of the quality of the contents.
