    Abstract: Provided is an ink-jet textile printing process imparting an ink to a cloth by ink-jet recording, which process comprises at least the following three steps of: (a) forming a mixed color area made of at least two different colors on said cloth by ejecting successively ink droplets using at least one of an yellow ink and a black ink and at least one ink selected from the group consisting of a red ink, a green ink and a blue ink, the adhered quantity of corresponding dyes in said mixed color area being from 0.025 to 1 mg/cm ; (b) dyeing said cloth having been subjected to the step(a) with the dyes adhered to said cloth by subjecting to a heat treatment; and (c) washing said cloth having been subjected to the step (b), to remove from said cloth a dye or dyes having not been adsorbed or fixed; and said mixed color area is formed by ejecting ink droplets in the order initiated with a black ink and terminated with an yellow ink. a

    Abstract: An ink-jet textile printing ink, comprising from 5% to 30% by weight of a reactive dye having at least one of a monochlorotriazine group and a vinyl sulfone group, and a water-based liquid medium, wherein said liquid medium comprises from 1% to 50% by weight of thiodiglycol and from 2% to 45% by weight of at least one organic solvent selected from a di-, tri-, or tetramer of oxyethylene, a di-, tri-, or tetramer of oxypropylene, and a mono- or di-C -C -alkyl ether of any of these di-, tri- or tetramers.

    Abstract: Provided is an ink jet printing method for printing inks of at least two colors on a cloth by an ink jet system which comprises at least three steps of: (a) the step of printing, on the cloth, the inks of at least two colors of a black ink and an another ink of at least one color selected from the group consisting of yellow, orange, red, magenta, blue and cyan so that the inks may at least partially overlap, (b) the step of thermally treating the cloth printed with the inks, and (c) the step of washing the thermally treated cloth, said cloth comprising a polyamide fiber, said black ink containing, as a dyestuff, at least one selected from the group consisting of C. I. Acid Black 24, 26, 52, 52:1, 109, 155, 172 and 222, C. I. Direct Black 19, 62 and 113, and a dyestuff represented by the formula (1) wherein M is an alkaline metal, ammonium or an amine, or the formula (2) wherein X is a hydrogen atom, a lower alkyl group or a phenyl group which may be substituted by an SO3M group; m is O or 1; M is an alkaline metal, ammonium or an amine; each of A, B and C is a benzene ring or a naphthalene ring which may have a substituent, but B and C are not simultaneously the naphthalene rings.

    Abstract: Disclosed herein is an ink-jet printing process comprising at least the steps of: (a) successively applying, as ink droplets, at least two inks of different colors to a cloth to form a color-mixed portion; (b) subjecting the cloth to a heat treatment to fix dyes contained in the inks to the cloth; and (c) washing the cloth to remove unfixed dyes from the cloth, wherein the inks comprise water, an organic solvent and individual reactive dyes different from each other in reaction rate, and have a pH within a range of from 4 to 10, and the pH of the ink containing a slower-reacting dye is made higher.
