An aqueous liquid composition containing a reactive dye of the following formula D-SO2X)n wherein D is an organic dye residue having 1 to 3 sulfonic acid grups, X is a group of -CH=CH2 or -CH2CH2Y in which Y is a splittable group by the action of an alkali, and n is a number of 1 or 2, in an amount of 5 to 50% by weight based on the weight of the composition, which composition is improved in storage stability at a low temperature, is produced by preparing an undemimeralized agueous solution of the dye of the above formula, dissolving at least one additive selected from lactams and aminoalcohols in the solution, controlling the resulting solution to a temperature of -10 DEG C. to 5 DEG C. to crystallized inorganic salts contained therein, and separating the crystallized inorganic salts, the said additive being used in an amount of 0.1 to 20% by weight based on the weight of the composition.
