Description

Verfahren zum Färben und Drucken von Celluloseestern oder -äthern Es ist gefunden worden, daß Monoaza!-farbstoffe, die als Kupplungskomponente in Parastellung substituierte Phenole oder deren in Orthostellung kupplungsfähige Homologe enthalten, sich in hervorragender Weise zur Herstellung von gelben bis orangen Färbungen und Drucken auf Celluloseestern und -äthern eignen. Die Diazoverbindungen können beliebiger Natur sein, doch dürfen sie nicht mehr als eine Sulfogruppe enthalten. Während die entsprechenden Farbstoffe ohne Hydroxylgruppen, wie z. B. Aminoazobenzol, Airinoazotoluol, auf Acetatseide phofiotrope Färbungen ergeben, zeichnen sich die beidem vorliegenden Verfahren verwendeten Farbstoffe dadurch aus, daß sie diesen großen Nachteil. nicht besitzen. (Gelbe phototrope Farbstoffe sind bekanntlich solche, die, b:esonders in Mischung mit Rot und Blau, nach kurzer Belichtung ihre Gilbe vorübergehend verlieren, sie aber im Dunkeln wiedergewinnen [vgl. Isolationserscheinungen bei Wollfärbungen].) Die ,gemäß der Erfindung verwendeten Farbstoffe sind deshalb zur Herstellung von Mischnuancen besonders wertvoll. Außerdem ergeben die Farbstoffe Färbungen von besonders guter Licht- und Chlorechtheit. B ei spi.el i kg Acetatseide wird in einem Färbebade von 2o bis 251, in den Zog des Farbstoffes p-Pb;enylendiamm: p-Kresol gelöst sind, 3/4 bis i Stunde bei 6o bis 7o° C gefärbt. Man erhält auf diese Weise eine lebhaftgoldgelbe Färbung von guter Licht- und Chlorechtheit.Process for dyeing and printing cellulose esters or ethers It has been found that monoaza! Dyes used as coupling components in Phenols substituted in the para position or their homologues capable of coupling in the ortho position contain, is an excellent way to produce yellow to orange colorations and printing on cellulose esters and ethers. The diazo compounds can be of any nature, but they must not contain more than one sulfo group. While the corresponding dyes without hydroxyl groups, such as. B. Aminoazobenzene, Airinoazotoluene, which produces phofiotropic colorations on acetate silk, stand out in the present process used dyes in that they big disadvantage. not own. (Yellow photochromic dyes are known to be those which, especially when mixed with red and blue, turn yellow after a short exposure temporarily lose it, but regain it in the dark [cf. Isolation phenomena in wool dyeings].) The dyes used according to the invention are therefore particularly valuable for the production of mixed shades. Also give the dyes Dyeings with particularly good light and chlorine fastness. For example 1 kg of acetate silk is in a dye bath from 2o to 251, in the pull of the dye p-Pb; enylenediamine: p-cresol are dissolved, stained for 3/4 to 1 hour at 6o to 7o ° C. One receives on this way a lively golden yellow color with good light and chlorine fastness.

Ersetzt man den im obigen Beispiel angeführtes Farbstoff durch die gleiche Menge des Farbstoffes Acetyl-p-phenylendiamiu p-Kresol, so erhält man auf der Acetyloellulosc ein schönes grünstichiges Gelb von sehr guten Echtheitseigenschaften. Der Farbstoff m-Chloraailin rp-Kresol färbt die Faser schön gelb; der Farbstoff p-Phenylendiamino-sulfosäurne----rp-Kresol färbt ebenfalls gelb.If the dye mentioned in the example above is replaced by the the same amount of the dye acetyl-p-phenylendiamiu p-cresol is obtained on Acetyloellulosc is a beautiful greenish yellow with very good fastness properties. The dye m-chloraailine rp-cresol gives the fiber a nice yellow color; the dye p-Phenylenediamino-sulfonic acids ---- rp-cresol also turns yellow.
