摘要:
Wasserlösliche Monoazoverbindungen entsprechend der allgemeinen Formel (1),
in welcher D Monosulfo- oder Disulfophenyl ist, die beide durch niederes Alkyl, niederes Alkoxy, Halogen, Carboxy und/oder niederes Alkanoylamino substituiert sein können, oder Mono-, Di- oder Trisulfonaphthyl ist, K als Rest einer Kupplungskomponente der para-Phenylenrest ist, der durch niederes Alkyl, niederes Alkoxy, Halogen, niederes Alkanoylamino, Ureido, Carbamoyl und/oder Sulfo substituiert sein kann, oder der 1,4-Naphthylen-Rest ist, der durch 1 oder 2 Sulfogruppen und/oder eine niedere Alkoxygruppe substituiert sein kann, R Wasserstoff oder niederes Alkyl ist, A Phenylen oder eine direkte Bindung ist, W eine direkte Bindung oder niederes Alkylen oder eine durch niederes Alkyl substituierte Aminogruppe ist, wobei A und W nicht gleichzeitig eine direkte Bindung sind, und die Gruppe -SO₂-X eine faserreaktive Gruppe der Vinylsulfonreihe ist. Die Azoverbindungen der Formel (1) sind faserreaktiv und besitzen sehr gute Farbstoffeigenschaften. Sie färben hydroxy- und/oder carbonamidgruppenhaltiges Material, insbesondere Fasermaterial, wie beispielsweise Cellulosefasermaterialien, Wolle und synthetische Polyamidfasern in farbstarken, kräftigen, echten Tönen. Sie sind insbesondere für den Ätz- und Reservedruck geeignet.
