The invention relates to reactive-group-containing monoazo dyestuffs of formula (I), their salts or mixtures thereof, wherein R1 signifies hydrogen, methyl, methoxy or ethoxy, R2 signifies hydrogen, methyl, NHCONH2 or NHCOCH3', RG signifies (a), (b) or (c), X signifies hydrogen or chlorine, Z signifie a group -CH = CH2, -CH2CH2W or mixtures thereof wherein W is a leaving group removable by alkali and -SO2-Z may be bonded in a meta- or para-position with respect to the azo group. These compounds are useful as reactive dyestuffs in printing or dyeing hydroxy-group-containing or nitrogen-containing organic substrates. |
