Fiber-reactive tetrazo dyes of the formula ##SPC1##
Wherein each of D.sub.1 and D.sub.2 represents a benzene residue which contains at least one sulphonic acid group, one of the two substituents Y.sub.1 and Y.sub.2 represents the HO group and the other represents the H.sub.2 N group, X represents a halogen atom and B represents a benzene residue which is devoid of sulphonic acid groups, are suitable dyes for dyeing and printing materials of the most diverse kind, especially for dyeing of cellulosic materials of fibrous structure by the exhaustion process. The dyes are characterized by increased reactivity and high degree of fixation.
