Verfahren zur Herstellung von echten Färbungen.
Es wurde die überraschende Beobachtung gemacht, dass die in der Imidgruppe substituierten Anthrachinonhydroazyne (Indanthrene) und ihre Derivate die bemerkenswerte Eigenschaft besitzen, die Faser auch in kalter Küpe kräftig anzufärben, während die nicht substituierten Idanthrene und deren Derivate vornehmlich nur in warmer Küpe (über 500) gute Färberesultate liefern. In manchen Fällen, wie bei dem einfachsten durch Kondensation von 1-Amino-2-halogenanthrachinon mit 1-Methylamino-2-halogenanthrachinon erhält lichen Methylindanthren, wird die Faser in kalter Küpo sogar bedeutend kräftiger angefärbt, wie bei den für die nicht substituierten Indanthrenen gebräuchlichen höheren Temperaturen.
Das Verfahren ist auch dadurch von hoher technischer Wichtigkeit, dass es nach demselben gelingt, die genannten Indanthrenderivate leicht mit anderen in kalter Küpe färbenden Produkten, wie z. B. Benzoylaminoanthrachinonen zu kombinieren und so zu äusserst echten Modetönen zu gelangen.
Beispiel.

Diese Lösung giesst man durch ein Sieb in ein Färbebad, das bestellt ist mit 1000 l kaltem Wasser, dem man 1 4 Natronlauge 30 Bé, 1 l Hydrosulfitlösung 17 Bé und 40 kg Kochsalz zugesetzt hat. Man rührt gut um, geht mit dem gut angefeuchteten Garn ein und färbt 3/., bis 1 Stunde kalt. Sodann wird das Garn herausgenommen, gut abgewunden, an der Luft ver-

Egalität.
Wie schon erwähnt, kann der Farbstoff nach diesem Verfahren mit einer grossen Anzahl auch in der Kälte färbender Küpenfarbstoffe der Anthrachinonreihe kombiniert werden. Es werden so die mannigfaltigsten Modenuancen von einer grossen Echtheit erzielt.
Besonders wichtig ist die Egalität der so erhaltenen Mischnuancen. Das neue Verfahren bedeutet somit einen erheblichen technischen Fortschritt, da blaue, kalt färbende Küpenfarbstoffe von solcher Kombinationsfähigkeit bisher überhaupt nicht bekannt waren.
Ganz analog verhalten sich die anderen in der Imidgruppe alkylierten Indanthrene nud deren Derivat.

Process for the production of real dyeings.
The surprising observation was made that the anthraquinone hydroazynes (indanthrenes) and their derivatives substituted in the imide group have the remarkable property of staining the fiber vigorously even in a cold vat, while the unsubstituted idanthrenes and their derivatives primarily only in a warm vat (over 500 ) deliver good dyeing results. In some cases, such as the simplest methylindanthrene obtainable by condensation of 1-amino-2-halogenanthraquinone with 1-methylamino-2-halogenanthraquinone, the fiber is even dyed significantly more vigorously in cold Küpo, as is the case with the unsubstituted indanthrenes higher temperatures.
The process is also of great technical importance that it succeeds after the same, the indanthrene derivatives mentioned easily with other products that dye in a cold vat, such as. B. to combine benzoylaminoanthraquinones and thus achieve extremely real fashion tones.
Example.
Regulation for 50 Ay cotton yarn.
10 methyl indanthrene (10% paste) are mixed with 40 liters of water at 400 C
EMI1.1
good and let stand for about 20 minutes, whereby the dye goes into solution. This solution is poured through a sieve into a dye bath filled with 1000 l of cold water to which 1 4 sodium hydroxide solution 30 Be, 1 l of hydrosulfite solution 17 Be and 40 kg of common salt have been added. Stir well, go in with the moistened yarn and dye 3 /., Cold for up to 1 hour. The thread is then taken out, well unwound, left in the air.
EMI1.2
Equality.
As already mentioned, according to this process, the dye can be combined with a large number of vat dyes of the anthraquinone series that also dye in the cold. The most varied of fashion nuances of great authenticity are achieved in this way.
The evenness of the mixed shades obtained in this way is particularly important. The new process thus represents a considerable technical advance, since blue, cold-dyeing vat dyes of this type were not known at all.
The other indanthrenes alkylated in the imide group and their derivatives behave in exactly the same way.
