    摘要: 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) ##STR1## wherein M is an alkaline metal, ammonium or an amine, or the formula (2) ##STR2## wherein X is a hydrogen atom, a lower alkyl group or a phenyl group which may be substituted by an SO.sub.3 M group; m is 0 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.
