Abstract

Abstract Translated from German Es werden Monoazoverbindungen mit faserreaktiven Farbstoffeigenschaften beschrieben, die als Diazokomponente ein durch zwei faserreaktive Gruppen der Vinylsulfon-reihe substituiertes Anilin und als Kupplungskomponente eine solche aus der Anilin-, Hydroxypyridon-, 5-Pyrazolon-oder 5-Aminopyrazol-Reihe besitzen. Sie eignen sich zum Färben von carbonamid- und/oder hydroxygruppenhaltigen Materialien, insbesondere Fasermaterialien, wie bevorzugt von Cellulosefasermaterialien. Monoazo compounds with fiber-reactive dye properties are described which have an aniline substituted by two fiber-reactive groups from the vinylsulfone series as the diazo component and one from the aniline, hydroxypyridone, 5-pyrazolone or 5-aminopyrazole series as the coupling component. They are suitable for dyeing materials containing carbonamide and / or hydroxyl groups, in particular fiber materials, such as preferably cellulose fiber materials.
