    Abstract: of the disclosure: Water-soluble monoazo compounds of the general formula (1) (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 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 aminonaphtholdisulfonic acid is bonded in meta- or para-position relative 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.

    Abstract: 1. Water-soluble azo compounds of the general formula (1) see diagramm : EP0094055,P17,F4 in which M represents a hydrogen atom or the equivalent of a metal, D is a benzene nucleus or a naphthalene nucleus, R**1 denotes a hydrogen atom or an alkyl group of 1 to 4 C-atoms or a sulfo group, R**2 is a hydrogen atom or an alkyl group of 1 to 4 C-atoms, R**3 represents a hydrogen atom, an alkyl group of 1 to 4 C-atoms or an alkoxy group of 1 to 4 C-atoms and R**4 denotes a hydrogen atom or an alkyl group of 1 to 4 C-atoms or an alkoxy group of 1 to 4 C-atoms, where R**1 , R**2 , R**3 and R**4 can be identical to or different from one another, Y is a fluorine atom or a bromine atom or, preferably, a chlorine atom and X in each case denotes a beta-sulfatoethyl group or a beta-thiosulfatoethyl group or a beta-chloroethyl group or a vinyl group, where the two X 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, respectively to the acylated amino group, and can be bonded in the naphthalene nucleus in any position, and the second group of the formula -SO3 M in the radical of the aminonaphtholdisulfonic acid is bonded in meta- or para-position relative to the acylated amino group.

    Abstract: Water-soluble dyestuffs are described which in the acid form possess the formula +TR wherein D is a benzene or naphthalene nucleus, R1 is linked to D in ortho-position to the azo group and means hydrogen, halogen, lower alkoxy, lower alkyl, carboxy or sulfo, R2 is hydrogen, halogen, lower alkyl, lower alkoxy or sulfo and X is the vinyl group or a sulfato-, chloro- or thiosulfatoethyl group, A is a bridging member preferably selected from the diphenylene, diphenylsulfone and diphenylamine series, Z and Z1 each represent a hydroxy or amino group with the proviso that each Z and each Z1 have the same meaning. These novel dyestuffs are prepared by diazotization and coupling of the corresponding diazo and coupling components in usual manner known in the art. The novel dyestuffs possess a very valuable fiber-reactivity and are suitable for dyeing natural and regenerated cellulose or natural, regenerated or synthetic polyamide fiber materials. They can easily be applied and fixed by application methods usual and known in the art, and yield on these fiber materials dyeings and prints which possess good fastnesses, especially fastnesses to light, to washing, to perspiration and to cross-dyeing. Their fixation degree on the fiber material and correspondingly their tinctorial strength are outstanding.
