PURPOSE: A reactive black dye composition is provided which shows excellent stability and discharge printing property in an alkaline dyeing bath when printing or continuous dyeing of cellulose fiber of rayon fiber and has improved contamination proof property regarding nylon when being applied to mixed fabric. CONSTITUTION: The reactive black dye composition contains a black dye compound of the formula (1), at least one compound selected from the formula (11) and at least one compound selected from the formula (12). In the formula (1), X is an isolative group by substitution reaction and M is a hydrogen or an equivalent metal. In the formula (11), R1 is an acetyl, a propionyl, a malanyl, a benzyl or a benzoyl, each R2 and R3 is a hydrogen, a methyl or a methoxy group and X is an isolative substituent by alkali. In the formula (12), each R1 and R2 is a hydrogen, a methyl or a methoxy group and X is an isolative substituent by alkali and A is a benzene compound represented by the formula (13), where n is an integer of 0-3 and R3 is a hydrogen, a methyl group or a carboxyl group, or a naphthalene compound of the formula (14), where each m and n is an integer of 0-3 and R4 is a hydrogen, a methyl group or a carboxyl group.
