    • The inkjet textile printing ink of the present invention includes a first reactive dye that has at least a sulfonate group and optionally further has an amide group and/or hydroxy group, a second reactive dye that has at least an amide group and/or hydroxy group and optionally further has a sulfonate group, a water-soluble organic solvent, and water. The number of sulfonate groups in one molecule of the second reactive dye is smaller than the number of sulfonate groups contained in one molecule of the first reactive dye, and the total number of sulfonate groups, amide groups, and hydroxy groups in one molecule of the second reactive dye is equivalent to the total number of sulfonate groups, amide groups, and hydroxy groups in one molecule of the first reactive dye, and the hue difference ΔS* between the second reactive dye and the first reactive dye is 4 or less.
    • 本发明的喷墨印花油墨包含具有至少一个磺酸盐基团且任选还具有酰胺基和/或羟基的第一活性染料,具有至少一个酰胺基和/或羟基的第二活性染料 并且任选地还具有磺酸盐基团,水溶性有机溶剂和水。 第二活性染料的一个分子中的磺酸盐基团的数量小于第一活性染料的一个分子中所含有的磺酸盐基团的数量,并且一个分子中的磺酸盐基团,酰胺基团和羟基的总数 第二反应性染料相当于第一反应性染料的1分子中的磺酸基,酰胺基和羟基的总数,第二反应性染料与第一反应性染料的色相差ΔS*为4以下。
