Abstract: Water-soluble compounds and their salts suitable as dyestuffs of the formula +TR in which D is a benzene or naphthalene nucleus, R1 and R2 are, inter alia, hydrogen, halogen, lower alkyl, lower alkoxy and sulfo, R1 being in ortho-position to the azo group, X is a fiber-reactive radical of the vinyl sulfone series, K1 and K2 are radicals of coupling components of the acetoacetarylide and pyrozolone series and K2 additionally denotes a radical of the sulfonaphthol series, the coupling components being bound to the triazine ring via amino groups, Y is a halogen atom, a sulfo group, a thio ether or oxygen ether radical, or a primary, secondary or tertiary amino group, A is an aliphatic, aliphatic-heterocyclic, aliphatic-aromatic or aromatic bridge member and n is zero or one. The novel compounds are prepared, for example, by reacting 2 mols of the diazo component with the fiber-reactive radical of the vinyl sulfone series with 1 mol of a bivalent coupling component containing the two radicals K1 and K2 linked to each other by the triazine ring, or 2 triazine radicals linked with each other by bridge member A; or by reacting one mol each of a monoazo compound consisting of the said diazo component with the fiber reactive radical and a coupling component K1 or K2 with a corresponding triazine radical additionally carrying a halogen atom capable of reacting with the amino group. The metal-free compounds can be transformed into the corresponding heavy metal complex, preferably copper, cobalt and chromium complex compounds, by treatment with an agent donating a heavy metal cation. The novel compounds are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural, regenerated and synthetic polyamides. They are distinguished by high tinctorial strength, a very good uptake from a long liquor, a good color-build up. The dyeings and prints obtained therewith have a high fastness to processing and in use.

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: The novel water-soluble disazo dyestuffs consist of two monoazo dyestuff moieties each containing as diazo component an amine of the benzene or naphthalene series and as coupling component an amino-naphthol-mono- or disulfonic acid. The two moieties are bonded to each other via a bridge member bound to the amino groups of the coupling components and comprising two triazine radicals each containing a halogen atom, a sulfonic acid group or a thio ether or oxygen ether group or an amino group and the diazo components contain a fiber-reactive radical of the vinyl sulfone series. The metal-free dyestuffs can be transformed into the corresponding heavy metal complex dyestuffs, preferably copper, cobalt and chromium complex dyestuffs, by treatment with an agent donating a heavy metal cation. The novel dyestuffs are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural, regenerated and synthetic polyamides. They are distinguished by a high tinctorial strength, a very good uptake from a long liquor, a good color- build up and good printing properties.

The two moieties are bonded to each other via a triazine radical which carries a halogen atom, and is bound to the amino groups of the coupling components and the diazo components contain a fiber-reactive radical of the vinyl sulfone series. To produce the dyestuffs 2 mols of the diazo compound carrying the fiber-reactive radical of the vinyl sulfone series is coupled with 1 mol of a bivalent coupling component consisting of 2 radicals of the aminonaphthol bound to the triazine ring via the amino groups, or two monoazo dyestuffs each synthesized from the aforesaid diazo component and an aminonaphthol-disulfonic acid coupling component are reacted with a 1,3,5-trihalogeno-triazine. The metal-free dyestuffs can be transformed into the corresponding heavy metal complex dyestuffs, preferably copper, cobalt and chromium complex dyestuffs, by treatment with an agent donating a heavy metal cation. The novel dyestuffs are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural, regenerated and synthetic polyamides. They are distinguished by clear shades, high tinctorial strength, a very good uptake from a long liquor and a good color-build up. The dyeings obtained therewith have a high fastness to processing and in use.
