摘要： Disazo compounds, processes for their preparation and their use as dyestuffs Described are fiber-reactive, water-soluble disazo compounds corresponding to the formula (1) given below, which are capable of dyeing fiber material containing hydroxy, amino, thiol and/or carboxamido groups, such as cellulose fibers, for example cotton, regenerated cellulose fibers, wool and synthetic polyamide fibers, in a high intensity and with good fastness properties. in which: W2 is a particular fiber-reactive grouping, D1 is phenyl or naphthyl, each optionally substituted by substituents customary in dyestuffs, and D2 is phenylene or naphthylene optionally substituted by substituents customary in dyestuffs, M is hydrogen or an alkali metal, R is hydrogen or sulfo and R1 is hydrogen, optionally substituted lower alkyl or optionally substituted phenyl.
