A reactive black dye compsn. is produced by dispersion-dissolving 5-30 wt.% cpd. of formula (II) contg. vinylsulfone cpd. and triazine cpd. and 1-10 wt.% cpd. of formula (III) in 60-90 wt.% cpd. of formula (I), and spray-drying the mixt. In the formulas, R is -COCH3 or -CONH2; R1 and R2 are each H, methyl, ethyl or methoxy; R3 is Cl, aromatic amine cpd. or (a); R4 is (a); X is -CH2CH2OSO3H. The dye compsn. is used in printing and dyeing cellulose fibers, and has a good stability.
