| titleOfInvention | Water-soluble azo dyestuffs |
| abstract | Abstract of the disclosure Water-soluble compounds and their salts suitable as dye-stuffs of the formula 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 alipha-tic, 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 com-ponent 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 tri-azine 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 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 correspond-ing heavy metal complex, preferably copper, cobalt and chro-mium 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 syn-thetic 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. |
