ABSTRACT:
An aqueous liquid dye composition comprising 5 to 50% by weight of a reactive dye represented by the following formula, ##STR1## wherein D denotes a sulfo group-containing organic dye residue, R.sub.1 and R.sub.2 independently of one another denote a hydrogen atom or a C.sub.1 to C.sub.4 alkyl group unsubstituted or substituted with a halogen atom or a hydroxyl, cyano, C.sub.1 to C.sub.4 alkoxy, carboxy, carbamoyl, C.sub.1 to C.sub.4 alkoxycarbonyl, C.sub.1 to C.sub.4 alkylcarbonyloxy, sulfo or sulfamoyl group, A denotes a phenylene group unsubstituted or substituted with one or two members selected from methyl, ethyl, methoxy, ethoxy, chlorine, bromine and sulfo, or a naphthylene group unsubstituted or substituted with one sulfo group, X denotes a halogen atom, and Y is a group of --SO.sub.2 CH.dbd.CH.sub.2 or --SO.sub.2 CH.sub.2 CH.sub.2 Z in which Z is a splittable group by the action of an alkali, 0.1 to 10% by weight of .epsilon.-caprolactam and the balance of water, the composition having a pH value of 3 to 7, which can be stored for a long period of time at a low temperature such as 5.degree. C. or lower without deterioration in its solution state.
