A water-soluble monoazo-dyestuff of the formula (1) (1) <IMAGE> in which X represents -CH=CH2 or -CH2-CH2-Z, the radical Z stands for hydroxyl, sulfato, chlorine, bromine, lower alkyl-sulfonyloxy, lower alkyl-sulfonylamino, phenyl-sulfonyloxy, lower alkyl-phenyl-sulfonyloxy, phenyl-sulfonylamino, lower alkyloyloxy, monosulfobenzoyloxy, phenoxy, di-(lower alkyl)-amino, tri-(lower alkyl)-ammonium, thiosulfato or phosphato, and A is a radical of a coupling component of the aminobenzene, hydroxybenzene amino-naphthalene, hydroxynaphthalene, N-naphthyl- or N-phenyl-amino-pyrazole, N-naphthyl- or N-phenyl-pyrazolone or of the acetoacetanilide series, the coupling component containing at least one water-solubilizing group, and a process for preparing these dyestuffs which are very suitable for the dyeing and printing of native and synthetic carbonamide-groups containing and native, regenerated or synthetic hydroxy-groups containing material, and yield, especially on cellulose fibrous materials in the presence of alkaline agents dyeings and prints of good to very good fastnesses to light and to wet-processing and of good stability to alkalis. The novel dyestuffs also have a very good color-build-up and yield dyeings and prints of high tinetorial strength.
