Abstract: Water-soluble fibre-reactive dyestuffs containing one or two fibre-reactive groups of the vinylsulfone series and one or two fibre-reactive groups of the fluoro-s-triazinyl-amino series. These dyestuffs can be applied on fibre materials containing hydroxy and/or carbonamide groups by known application and fixation techniques for fibre-reactive dyes to yield deep and fast dyeings on these materials.

Abstract: Water-soluble disazo dyestuffs of the formula ##STR1## 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, ##STR2## 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: A process for dyeing or printing fiber materials containing hydroxy and/or carbonamide groups, in which process a fiber-reactive, water-soluble dyestuff of the type defined below is applied to the fiber material and is then fixed on the fiber material at an ordinary or elevated temperature, if appropriate in the presence of agents having an alkaline reaction. This water-soluble dyestuff, which contains at least one sulfonic acid group, contains one or more groupings belonging to the group comprising the formulae (1a), (1b) and (1c)--SO.sub.2 --CH.dbd.CH.sub.2 (1a)--SO.sub.2 --CH.sub.2 --CH.sub.2 --Hal (1b)--SO.sub.2 --CH.sub.2 --CH.sub.

Abstract: Water-soluble anthraquinone compounds of the formula (1) ##STR1## wherein M is a hydrogen atom or the equivalent of a metal, such as in particular sodium or potassium, R is a hydrogen atom, a halogen atom, the methyl, ethyl, methoxy, ethoxy or carboxy group, and X is the vinyl group, a .beta.-thiosulfatoethyl, .beta.-sulfatoethyl or the .beta.-chloroethyl group. These compounds may be prepared in a manner know by itself by reacting an anthraquinone compound of the formula (2) ##STR2## wherein M is defined as above, with an equimolar quantity of cyanuric chloride and an amine of the formula (4) ##STR3## wherein R and X are defined as above, or by reacting said anthraquinone compound of the formula (2) with a compound of the formula (5) ##STR4## wherein R and X are defined as above. The new compounds of the formula (1) are valuable dyestuffs having fiber-reactive properties.

Abstract: Dihalogenotriazinylamino-naphthol compounds of th formula (1) ##STR1## in which the radicals X each mean fluorine, chlorine or bromine, R is hydrogen or alkyl of 1 to 4 C-atoms, M is hydrogen or the equivalent of a metal, and Z is hydrogen or a group of the formula --SO.sub.3 M with M having the abovementioned meaning, are prepared in water as reaction medium by reaction of an aminonaphthol compound of the formula (2) ##STR2## in which R, M and Z have the abovementioned meanings with a cyanuric halide compound of the formula (3) ##STR3## in which the radicals X have the abovementioned meanings, at pH 5 or smaller than 5 by introducing the aminonaphthol compound of the formula (2) in solid, undissolved form into the reaction, and carrying out the reaction in suspension.
