Abstract

Abstract Translated from German Reaktivfarbstoffe der Formel worin (R) n für n Substituenten R steht, die unabhängig voneinander C 1-4 -Alkyl, C 1-4 -Alkoxy, Carboxy oder Halogen sein kön- ) nen, n = 0 bis 3, m = 1 bis 2, und X ein Rest der Formel worin R 1 und R 2 unabhängig voneinander Wasserstoff oder gegebenenfalls substituiertes C 1-4 -Alkyl, A C 3-7 -Alkylen, das durch Halogen, Hydroxy, Carboxy, Sulfo, Phenyl, Sulfophenyl oder C 1-4 -Alkoxycarbonyl substituiert sein kann, oder Cyclohexylen, das durch C 1-4 -Alkyl substituiert sein kann, oder worin die Gruppe -N(R 1 )-A-N(R 2 )- 1,4-Piperazindiyl ist, und Y Fluor, -NH 2 oder eine substituierte Aminogruppe ist, eignen sich zum Färben und Bedrucken von cellulosehaltigen Fasermaterialien und ergeben nass- und lichtechte Färbungen in leuchtend blauen Tönen. Reactive dyes of the formula wherein (R) n stands for n substituents R, which can independently of one another be C 1-4 alkyl, C 1-4 alkoxy, carboxy or halogen), n = 0 to 3, m = 1 to 2, and X is a radical of the formula wherein R 1 and R 2 independently of one another are hydrogen or optionally substituted C 1-4 -alkyl, AC 3-7 -alkylene, which can be substituted by halogen, hydroxy, carboxy, sulfo, phenyl, sulfophenyl or C 1-4 -alkoxycarbonyl, or cyclohexylene, which may be substituted by C 1-4 alkyl, or wherein the group is -N (R 1 ) -AN (R 2 ) - 1,4-piperazinediyl, and Y is fluorine, -NH 2 or a substituted amino group is suitable for dyeing and printing cellulosic fiber materials and results in wet and lightfast dyeings in bright blue tones.
