    Abstract: Water-soluble disazo dyestuffs of the formula which contain a 1-amino-8-naphthol-3,6- or -4,6-disulfonic acid moiety as a bivalent coupling component and which contain diazo components with fibre-reactive groups characterized by the inclusion of one or two chloro-triazinyl groups and one or two of the six groups defined by the substituent Z, namely, CH2SO2CH2CH2OSO3H; SO2CHCH2; +TR each of which are connected to the benzene moiety of the diazo component; the chloro-triazinyl group is further substituted by a substituted or unsubstituted phenylamino or substituted or unsubstituted naphthylamino group, a substitutent of which may be one of the six groups defined by the Z substituent; if there is only one chloro-triazinyl group in the compound, then the diazo component is also substituted by one of the Z substituents; these compounds are dyestuffs which exhibit a good fixation degree of the dyestuffs in fabrics.

    Abstract: Water-soluble coloured compounds containing one or two fibre-reactive groups of the general formula in bound form; in this formula, R denotes a hydrogen atom or an alkyl group of 1 to 4 C atoms; R denotes a hydrogen atom or an alkyl group of 1 to 4 C atoms; A denotes the phenylene radical or a naphthylene radical, each of which can be substituted by one or two substituents from the group consisting of chlorine, bromine, alkyl of 1 to 4 C atoms, alkoxy of 1 to 4 C atoms, hydroxyl, carboxyl and sulpho; M denotes a hydrogen atom or an alkali metal atom or the equivalent of an alkaline earth metal atom. These novel water-soluble coloured compounds have very good fibre-reactive dye properties and produce, by the dyeing and printing processes customary in industry for fibre-reactive dyes, dyeings and prints of high colour strength and good to very good fastness properties on, for example, cellulose fibre materials; they can be prepared analogously to known procedures, for example by reaction of an amino-containing coloured compound with cyanuric fluoride and an aniline or naphthylamine compound containing a beta -thiosulphatoethylsulphonyl group.
