<p>PURPOSE:To provide the title ink which has excellent long-term dispersion stability and does not cause the clogging of nozzles, etc., consisting of a specified reactive disperse dye, a nonionic surfactant, an anonic surfactant, water and an alkali-generating agent. CONSTITUTION:1-30% (by weight; the same applies hereinbelow) water-insoluble or difficultly water-soluble reactive disperse dye (A) of formula I (wherein D is a residue of a water-insoluble dye; X is O, -NH-, YOR<1> or NR<2>R<3>; R<1>, R<2> and R<3> are each H, a (substd.)alkyl, an aryl or an aralkyl group; R<2> and R<3> may be combined together to form a five- or six-membered nitrogen-contg. heterocyclic ring), 0.2-75.2% mixture (B) of a nonionic surfactant of formula II or III (wherein R<4> and R<5> are each H or alpha-methylbenzyl; R<6> is H or methyl; R<7> is H, methyl or alpha-methylbenzyl provided that one of R<5>, R<6> and R<7> is alpha- methylbenzyl; n is 7-150; m is 6-30) and an anionic surfactant of formula IV (wherein M is Na, K or ammonium salt) and 0.5-15% alkali generating agent (C) of formula V (wherein X<1>, X<2> and X<3> are each Cl or Br; M is Na, K or ammonium) are dissolved in 23.3-98.3% water.</p> |
