PURPOSE:To obtain the ink compsn. which is clear and stable, contains a reactive dye in a concn. high enough, and does not cause viscosity increase, crystal precipitation, etc., even if left standing for a long time by incorporating a specific reactive dye into an ink compsn. CONSTITUTION:The ink compsn. for fiber contains at least one reactive dye of the formula (wherein M is Na or K). The compsn. is based on a liq. medium which at least contains water, pref. deionized water, and a hydrophilic org. solvent. The solvent is selected so as to act as a drying retarder to prevent the occurrence of a solid matter, to act as a viscosity-controlling agent, and not to prevent the dissolution of the dye. |
