PATENTAMT.PATENT OFFICE.
In dem Patent 71199 ist ein Verfahren beschrieben zur Darstellung von schwarzen Disazofarbstoffen, darin bestehend, dafs man 2 Molecule gewisser Diazoverbindungen der Benzoloder Naphtalinreihe mit 1 Molecül Ci1 a4-Amidonaphtol a3-monosulfosäure in alkalischer Lösung combinirt;Patent 71199 describes a process for the preparation of black disazo dyes, which consists in combining 2 molecules of certain diazo compounds of the benzene or naphthalene series with 1 molecule of Ci 1 a 4 -amidonaphthol a 3 -monosulfonic acid in an alkaline solution;
•Es hat sich gezeigt, dafs auch die (in bekannter Weise auf der Faser fixirte) Diazoverbindurig des Primulins zur Erzeugung derartiger schwarzer Disazofarbstoffe geeignet ist, wenn man dieselbe mit neutralen oder schwach alkalischen Lösungen der genannten oder auch der isomeren Ci1 a4-Amidonaphtol-a2-monosulfosäure zusammenbringt.It has been shown that the diazo compound of primulin (fixed on the fiber in a known manner) is also suitable for the production of such black disazo dyes if it is mixed with neutral or weakly alkaline solutions of the above or the isomeric Ci 1 a 4 amidonaphthol -a 2 -monosulfonic acid brings together.
Ueberraschend ist, dafs hier die Bildung von Disazofarbstoff eintritt, da die O1Ct4-AmIdO-naphtolsulfosäure mit dem auf der Faser fixirten Diazoprimulin unter Umständen zur Einwirkung gelangt, welche für die Bildung· von Disazofarbstoff vollständig ungeeignet erscheinen. Denn beim Eintauchen des mit Disazoprimulin beladenen Stoffs in die Lösung der CL1 ai - Amidonaphtolsulfosäure befindet sich letztere naturgemäfs in einem enormen Ueberschufs gegenüber Diazoprimulin. Trotzdem aber greift das letztere schneller zum zweiten Mal in den von ihm im ersten Moment gebildeten ungelösten Monoazofarbstoff ein, als in ein neues Molecül des ursprünglichen in Lösung befindlichen Entwicklers.It is surprising that the formation of disazo dye occurs here, since the O 1 Ct 4 -amido-naphthol sulfonic acid with the diazo primulin fixed on the fiber may come into action which appear completely unsuitable for the formation of disazo dye. Because when the substance loaded with disazoprimulin is immersed in the solution of CL 1 a i - amidonaphthol sulfonic acid, the latter is naturally in an enormous excess compared to diazo primulin. Nevertheless, the latter intervenes more quickly for the second time in the undissolved monoazo dye formed by it in the first moment than in a new molecule of the original developer in solution.
Bei Anwendung der Ct1 ai - Amidonaphtol-Ä3-monosulfosäure entsteht eine blauschwarze Färbung, während die isomere «2-Säure einen mehr violettschwarzen Ton veranlafst. Derartige Effecte sind bei Verwendung von Ct1 a4-Amidonaphtol-ß2 ßs-disulfosäure an Stelle der genannten Monosulfosäuren zufolge der geringen Reactionsenergie jener Säure nicht entfernt erreichbar. When using the Ct 1 a i - amidonaphtol-Ä 3 -monosulfonic acid, a blue-black color is produced, while the isomeric « 2 -acid causes a more violet-black tone. Such effects can not be remotely achieved when using Ct 1 a 4 -amidonaphtol-ß 2 ß s -disulphonic acid instead of the monosulphonic acids mentioned, owing to the low reaction energy of that acid.
Eine in bekannter Weise hergestellte, etwa 4 procentige Färbung von Primulin auf Baumwolle wird nach bekannter Methode diazotirt.A 4 percent staining of primulin on cotton produced in a known manner is diazotized according to the known method.
ι ο kg der so präparirten Waare (Trockengewicht) werden hierauf in ein Entwickelungsbad eingeführt, welches hergestellt ist durch Lösen von 1,8 kg A1 a^-Amidonaphtol-ag-monosulfosäure in 0,9 kg Natronlauge 400 B. und 1 50 1 Wasser.ι ο kg of the goods prepared in this way (dry weight) are then introduced into a developing bath which is prepared by dissolving 1.8 kg of A 1 a ^ -amidonaphthol-ag-monosulfonic acid in 0.9 kg of sodium hydroxide solution 40 0 B. and 1 50 1 water.
