Description

Verfahren zur Herstellung von wasserunlöslichen Azofarbstoffen im Zeugdruck Zusatz zum Patent 704 54I Gegenstand des Patents 7o4 54I ist ein Verfahren zur Herstellung von wasserunlöslichen Azofarbstoffen im Zeugdruck. Das Verfahren besteht darin, daß man alkalische Gemische aus Arylnitrosaminen oder Wasser- bzw. alkalilöslichen Aryldiazoamino- oder -iminoverbindungen, die keine wasserlöslichmachenden Gruppen im Diazorest enthalten, wie sie z. B. durch Kondensation von Diazoverbindungen mit primären aromatischen, sekundären aliphatischen, 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 Addendum to patent 704 54I The subject of patent 7o4 54I is a process for the production of water-insoluble azo dyes in fabric printing. The procedure consists in using alkaline mixtures of aryl nitrosamines or water or alkali-soluble aryldiazoamino or imino compounds that are not water-solubilizing Contain groups 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 1,3-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.

Es wurde nun gefunden, daß man ebenso wertvolle wasserunlösliche Azofarbstoffe im Zeugdruck herstellen kann, wenn man an Stelle der in dem Verfahren nach Patent o4 54 i als Azokomponenten verwendeten Metallkomplexverbindungen hier Metallkomplexverbindungen von wasserunlöslichen Azofarbstoffen aus o-Oxy- oder o-Carboxydiazoverbindungen und I, 3-Diaminobenzol oder I-Amino-3-oxybenzol oder deren zweimal kuppelnde Substitutionsverbindungen verwendet. Diese Azokomponenten sind z. B. erhältlich nach dem Verfahren der Patentschrift 6I8 748. Metallkomplexhaltige o-Oxyazofarbstoffe können aber auch aus o-Halogenaminen oder o-Alkoxyaminen als Diazokomponenten unter Abspaltung des Halogens oder Aufspaltung der Alkoxygruppen hergestellt werden.It has now been found that valuable water-insoluble azo dyes can also be used can produce in stuff printing, if you replace the in the process according to patent o4 54 i metal complex compounds used as azo components here metal complex compounds of water-insoluble azo dyes from o-oxy or o-carboxydiazo compounds and I, 3-diaminobenzene or I-amino-3-oxybenzene or their twice coupling substitution compounds used. These azo components are e.g. B. obtainable by the process of the patent 6I8 748. Metal complex-containing o-oxyazo dyes can also be obtained from o-haloamines or o-alkoxyamines as diazo components with elimination or splitting of the halogen of the alkoxy groups.

Das vorliegende Verfahren bietet den Vorteil, daß danach - tiefere Brauntöne erhalten werden, als sie nach bekannten Verfahren mit vergleichbaren Kombinationen erhältlich sind. Beispiel I Eine Druckpaste, die in Iooo Gewichtsteilen 28 Gewichtsteile der Diazoaminoverbindung aus I-Amino-2-methoxy-5-chlorbenzol und Methylaminoessigsäure, 32 Gewichtsteile Kupferkomplex des essigsauer gekuppelten Monoazofarbstoffes aus diazotiertem i-Amino-2-oxy-5-chlorbenzol und i-Amino-3-oxybenzol, 3o Gewichtsteile Natronläuge 38° 8e, 5o Gewichtsteile Äthylenglykol, 5oo Gewichtsteile neutrale Stärketragantverdickting, Rest Wasser enthält, wird aufgedruckt, getrocknet, 5 Minuten im Essigsäure-Ameisensäure-Dampf gedämpft, gespült, geseift, gespült und getrocknet. Man erhält einen sehr vollen, tiefbraunen Druck von guten Echtheitseigenschaften.The present method offers the advantage that afterwards - deeper Brown tones can be obtained when using known methods with comparable combinations are available. Example I A printing paste which, in Iooo parts by weight, contains 28 parts by weight the diazoamino compound from I-amino-2-methoxy-5-chlorobenzene and methylaminoacetic acid, 32 parts by weight of the copper complex of the acetic acid-coupled monoazo dye diazotized i-amino-2-oxy-5-chlorobenzene and i-amino-3-oxybenzene, 30 parts by weight Sodium hydroxide solution 38 ° 8e, 50 parts by weight Ethylene glycol, 500 parts by weight neutral starch carrier thickening, the remainder contains water, is printed on, dried, Steamed, rinsed, soaped, rinsed and steamed for 5 minutes in acetic acid-formic acid steam dried. A very full, deep brown print with good fastness properties is obtained.

An Stelle des Kupferkomplexes des satuer gekuppelten Monoazofarbstoffes kann man auch den Kupferkomplex des alkalisch gekuppelten Farbstoffes verwenden. Beispiel Eine Druckpaste, die in Iooo Gewichtsteilen 28 Gewichtsteile der Diazoaminoverbindung aus I-Amino-z-methoxy-5-chlorbenzol und Methylaminoessigsäure, 3I Gewichtsteile Kupferkomplex des Monoazofarbstoffes aus diazotiertem I Amino-2-oxy-5-chlorbenzol und I, 3-Diaminobenzol, 5o Gewichtsteile Äthylenglykol, 5oo Gewichtsteile neutrale Stärke tragantverdickung, Rest Wasser enthält, wird, wie im Beispiel l beschrieben, gedruckt und entwickelt. Man erhält einen rötlichbraunen Druck.Instead of the copper complex of the satuer coupled monoazo dye the copper complex of the alkaline-coupled dye can also be used. Example A printing paste which, in 100 parts by weight, contains 28 parts by weight of the diazoamino compound from I-amino-z-methoxy-5-chlorobenzene and methylaminoacetic acid, 3I parts by weight Copper complex of the monoazo dye from diazotized I-amino-2-oxy-5-chlorobenzene and I, 3-diaminobenzene, 50 parts by weight of ethylene glycol, 500 parts by weight of neutral Starch tragacanth thickening, the remainder containing water, is, as described in Example 1, printed and developed. A reddish-brown print is obtained.

Beispiel 3 Eine Druckpaste, die in Iooo Gewichts teilen 28 Gewichtsteile der Diazoaminoverbindung aus I Amino-e-methoxy-5-chlorbenzol und Methylaminoessigsäure, 42 Gewichtsteile Kupferkomplex des Monoazofarbstoffes aus diazotiertem I-Amino-2-oxy-5-chlorbenzol und I-(4'Methylphenylamino)-3-oxybenzol, 3o Gewichtsteile Natronlauge 38° 8e, 5oo Gewichtsteile neutrale Stärketragantverdickung, Rest Wasser, enthält, wird, wie im Beispiel I beschrieben, gedruckt und entwickelt. Man erhält einen tiefbraunen Druck.Example 3 A printing paste which divides 28 parts by weight into Iooo weight the diazoamino compound from I amino-e-methoxy-5-chlorobenzene and methylaminoacetic acid, 42 parts by weight of the copper complex of the monoazo dye from diazotized I-amino-2-oxy-5-chlorobenzene and I- (4'-methylphenylamino) -3-oxybenzene, 3o parts by weight of sodium hydroxide solution 38 ° 8e, 5oo Parts by weight of neutral starch thickener, the remainder being water, will contain, like described, printed and developed in Example I. You get a deep brown Pressure.
