The reactive black dye composition of formula (I) is prepared by coupling 2 moles of aromatic compound of formula (II) with 1 mole of a compound of formula (III-1), 1 mole of a compound of formula (III-2) and 1 mole of a compound of formula (III-3). In the formulas X is a group like -SO3H, which can be isolated by alkylating reaction; R1 and R2 are independently H, methyl or methoxy. Particularly the addition amounts of compounds of formulas (III-1), (III-2) and (III-3) are 55-57 %, 5-10 %, and 20-25 %, respectively.
