PURPOSE:To provide the title compsn. having excellent low-temperature storage stability, containing a specified reactive dye and lactams and/or aminoalcohols. CONSTITUTION:5-50wt% at least one reaction dye (A) selected from among compds. of formula I (wherein D is a residue of an org. dye having 1-3 sulfo groups; X is a group of formula II or III; Y is a group which an be removed by the action of an alkali; and n is 1 or 2) is blended with 0.1-20wt%, pref. 0.5-8wt%, lactam (e.g., epsilon-caprolactam) and/or aminoalcohol (e.g., triethanolamine) (B). The pH of the mixture is adjusted to 3-7. If desired, a pH buffering soln., etc. are added thereto. The mixture is then kept at a temp. of -10-5 deg.C for 1-10hr. Inorg. salts including Glauber's salt are removed to obtain the title compsn. having a Glauber's salt content of not higher than 2.5wt%.
