Description

Verfahren zur Herstellung von wasserunlöslichen Azofarbstoffen im Zeugdruck Es wurde gefunden, daß man wasserunlösliche Azofarbstoffe im Zeugdruck herstellen kann wenn man alkalische Gemische aus Arylnitrosaminen oder Wasser- bzw. alkalilöslichen Aryldiazoamino- oder -iminoverbindungen, die keine wasserlöslich machenden Gruppen im Diazorest enthalten, wie sie z. B. durch Kondensation von Diazoverbindungen mit primären aromatischen, sekundären aIiphatischen, aromatischen und heterocyclischen Basen oder Cyanamid bzw. Cyanamidcarbonsäure erhältlich sind, und Metallkomplexverbindungen von wasserunlöslichen Azofarbstoffen aus 'o-Oxy- oder o-Carboxydiazoverbindungen und i, 3-Dioxybenzol oder dessen zweimal kuppelnden Substitutionsverbindungen auf die Faser bringt und die Färbung in üblicher Weise durch Verhängen., Dämpfen oder durch Behandeln mit verdünnten Säuren oder sauren Dämpfen -entwickelt. Man erhält auf diese Weise vorwiegend braune ausgiebige Drucke von guten Echtheitseigenschaften.Process for the production of water-insoluble azo dyes in Stuff printing It has been found that water-insoluble azo dyes can be used in stuff printing can be produced if alkaline mixtures of aryl nitrosamines or water or alkali-soluble aryldiazoamino or imino compounds that are not soluble in water making groups contained in the diazo radical, as z. B. by condensation of diazo compounds with primary aromatic, secondary aliphatic, aromatic and heterocyclic Bases or cyanamide or cyanamide carboxylic acid are available, and metal complex compounds of water-insoluble azo dyes from 'o-oxy or o-carboxydiazo compounds and i, 3-dioxybenzene or its twice coupling substitution compounds the fiber brings and the coloring in the usual way by hanging., steaming or -developed by treatment with dilute acids or acidic vapors. You get in this way predominantly brown extensive prints with good fastness properties.
