- 1 - Abstract of the disclosure: Water-soluble monoazo compounds of the general formula (1) Image (1) in which M represents a hydrogen atom or the equivalent of a metal, D is a benzene nucleus or a naphthalene nucleus, R1 denotes a hydrogen atom or an alkyl group of 1 to 4 carbon atoms or a sulfo group, R2 is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms, R3 represents a hydrogen atom, an alkyl group of 1 to 4 carbon atoms or an alkoxy group of 1 to 4 carbon atoms and R4 denotes a hydrogen atom or an alkyl group of 1 to 4 carbon atoms or an alkoxy group of 1 to 4 carbon atoms, where R1, R2, R3 and R4 can be identical to or different from one another, Y is a fluorine atom or a bromine atom or, preferably, a chlorine atom and - 2 - X in each case denotes a .beta.-sulfatoethyl group or a .beta.-thio- sulfatoethyl group or a .beta.-chloroethyl group or a vinyl group, where the two Xs can be identical to or different from one another, and the group(s) of the formula -SO2-X are bonded in the benzene nucleus in meta- or para-position relative to the azo group or acylated amino group and can be bonded in the naphthalene nucleus in any position and the second group of the formula -SO3M in the radical of the aminonaphthol- disulfonic acid is bonded in meta- or para-position rela- tive to the acylated amino group. These compounds of the formula (1) are prepared in analogy to known methods from the components evident from the formula (1) (the diazo component with the moiety D, cyanuric chloride, cyanuric bromide or cyanuric fluoride, the 1-amino-8-naphthol-3,6- or -4,6-disulfonic acid and the aniline compound with the group -SO2-X). They have very good fiber-reactive dyestuff properties and produce, for example on cellulose fiber materials, deep and fast dyeings and prints.
