Description
Zusatzpatent zum Hauptpatent Nr. 221018. Verfahren zur Herstellung eines ätzbeständigen Beizenf & rbstoffes. Im Hauptpatent wird ein Verfahren be schrieben, gemäss welchem ein Körper der Formel:
EMI0001.0005
mit einem Nitrosokörper eines in Metastel- lung substituierten '-Dälkylanilins konden siert wird, wobei interessante Farbstoffe ent stehen.
Speziell wird das aus dem oben er wähnten Ausgangskörper durch Kondensa tion mit Nitrosodiimethyl-m-chloranilin er haltene Produkt beansprucht.
Wie weiter gefunden wurde, erhält man einen Farbstoff von ähnlicher Eigenschaft, wenn das Nitrosodimethyl - m - ehlora.nilin dureh Nitrosodiäthyl-m-toluidinersetzt wird.
Dass Verfahren wird durch folgendes Bei spiel erläutert: Beispiel: 102 g des Kondensationsproduktes aus 1 Mol. 2-Naphthylamin-5-sulfonsäure und 2 Mal. p-Aminosalicylssäure werden mit 60 g NitrosodiAthyl-meta-to:luidin-clil.orhydrat und 500 g Alkohol verrührt und das Reaktions- gemisch am Rüökflusskühler zum Sieden er hitzt.
Die Masse färbt sich bald violett, hernach schwarzviolett und der sich bildende Farbstoff scheidet sich aus. Nach ungefähr 1i/2 bis 13/4 Stunden ist,die Kondensation be endet. Fas wird unter Rühren, erkalten ge, lassen und abfiltriert. Das Produkt wird mit wenig Alkohol und alsdann mit Wasser ge waschen, zum Schluss in ammoniakhaltigem Wasser gelöst und ausg.esalzen.
Der neue Farbstoff löst sich in Wasser mit violettschwarzer Farbe. Durch Ansäuern wird die Farbstoffsäure ausgefällt. In kon- zentrierter .Schwefelsäure geht der Farbstoff mit gelbbrauner Farbe in Lösung, woraus er beim Zusatz von Wasser in Form von violetten Flocken wieder ausgeschieden wird.
Im Chromdruck liefert dieser Farbstoff auf Naturseide und Viskose blauecliwarze. ätzbest.ä.ndige Farbtöne, die mit einer hy dro- sulfithaltigen Druckpaste überbrückt werden können, ohne dass eine wesentliche Vermin- derung der Fa.rbst:ärke eintritt. Der Farb stoff ist demnach geeignet, im Buntätzdrucl@ verwendet zu werden.
Additional patent to main patent No. 221018. Process for the production of an etch-resistant stain dye. The main patent describes a process according to which a body of the formula:
EMI0001.0005
is condensed with a nitroso body of a '-dälkylaniline substituted in the meta position, whereby interesting dyes arise.
Specifically, the product obtained from the above-mentioned starting body by condensation with nitrosodiimethyl-m-chloroaniline is claimed.
As was further found, a dye with similar properties is obtained if the nitrosodimethyl-m-ehlora.niline is replaced by nitrosodiethyl-m-toluidine.
The process is illustrated by the following example: Example: 102 g of the condensation product from 1 mol. 2-naphthylamine-5-sulfonic acid and twice. p-Aminosalicylic acid is stirred with 60 g of nitrosodiAthyl-meta-to: luidine-clil.orhydrate and 500 g of alcohol and the reaction mixture is heated to the boil on the reflux condenser.
The mass soon turns violet, then black-violet and the dye that forms is precipitated. After about 1 1/2 to 13/4 hours, the condensation will end. Fas is stirred, allowed to cool, and filtered off. The product is washed with a little alcohol and then with water, finally dissolved in water containing ammonia and salted out.
The new dye dissolves in water with a purple-black color. The dye acid is precipitated by acidification. In concentrated sulfuric acid, the yellow-brown dye dissolves, from which it is excreted again in the form of violet flakes when water is added.
In chrome printing, this dye produces blue and purple on natural silk and viscose. Etch-resistant color tones that can be bridged with a hydrosulphite-containing printing paste without any significant reduction in the color. The dye is therefore suitable for use in the Buntätzdrucl @.
