<p>A reactive dye composition comprising at least one alkylnaphthalenesulfonic acid/formaldehyde condensate and a compound represented by the following formula, <IMAGE> wherein D is an organic dye residue having at least one sulfo group, R1 and R2 are independently a hydrogen atom or a C1 to C4 alkyl group unsubstituted or substituted with a halogen atom or a hydroxy, cyano, alkoxy, carboxy, carbamoyl, alkoxycarbonyl, alkylcarbonyloxy, sulfo or sulfamoyl group, A is a phenylene group unsubstituted or substituted with one or two substituents selected from chlorine and bromine atoms and methyl, ethyl, methoxy, ethoxy and sulfo groups, or a naphthylene group unsubstituted or substituted with one sulfo group, X is a halogen atom, and Y is -SO2CH=CH2 or -SO2CH2CH2Z in which Z is a group capable of being split by an alkali, which composition is very readily soluble in water and aqueous alkaline solution, so that a dyeing or printing of cellulose fiber materials can be effectively carried out even by one-bath pad dyeing or one-phase printing methods to give a dyed product of a deep color having excellent levelness and no speck.</p> |
