PURPOSE: Provided is a reactive black dye composition excellent in the fastness of washing and the fastness of sunlight, which has excellent stability in an alkali dyebath when dyeing cellulose fiber and rayon fiber and low contamination to other fiber when mix-dyeing. CONSTITUTION: The reactive black dye composition comprises 60-95wt% of a dye compound represented by the formula(I), 2-15wt% of at least one dye compound represented by the formula(II)-(VI), and 2-30wt% of at least one dye compound represented by the formula(VII). In the formula, X is a group capable of esterification by substitution, M is hydrogen or a metal salt, A is chloro or fluoro, R1, R2, R3 are independently hydrogen, methyl, ethyl, methoxy, ethoxy, R4 is -CH2CH2OS3H or -CH2=CH2, n is an integer of 0-2, R5 is hydrogen, methyl, ethyl, methoxy, ethoxy, carboxyl, or chloro, Y is hydrogen or sulfone, Y1 is hydrogen, sulfone, carboxyl, -CH2CH2OS3H, -CH2=CH2, Y2 is hydrogen, methyl, ethyl, methoxy, ethoxy, sulfone, carboxyl, Z1 is hydrogen, and Z2 is hydrogen, methyl, ethyl.
