Beim Erhitzen von 2 · 2'- Dimethyl -1 · 1'-dianthrachinonyl oder dessen Derivaten für sich allein oder mit wasserentziehenden Mitteln entstehen neue wertvolle Körper, welche verschiedenartiger Verwendung fähig sind.On heating 2 · 2'-dimethyl -1 · 1'-dianthraquinonyl or its derivatives by themselves or with dehydrating agents, new valuable bodies arise, which are more diverse Are able to use.
So hat sich gezeigt, daß sich diese Produkte in hervorragender Weise zum Färben und Drucken der vegetabilischen Faser eignen. Be-It has been shown that these products are excellent for dyeing and Printing the vegetable fiber is suitable. Loading
. handelt man sie nämlich mit alkalischen Reduktionsmitteln, z. B. Hydrosulfit, so erhält man eine lebhaft rote, rhodaminähnlich gefärbte küpenartige Lösung, aus welcher Baumwolle mit roter Farbe angefärbt wird. Diese Färbung geht beim Waschen in ein leuchtendes Orange bis Gelb von ausgezeichneter Echtheit über.. if they are dealt with with alkaline reducing agents, z. B. hydrosulfite, a bright red, rhodamine-like color is obtained vat-like solution from which cotton is dyed red. This color turns into a bright when washed Orange to yellow of excellent authenticity.
Es liegen hier also die ersten Vertreter einer neuen Klasse rötlichgelber bis gelber und dabei stickstofffreier Küpenfarbstoffe vor.So here are the first representatives of a new class, reddish-yellow to yellow and nitrogen-free vat dyes.
Um die Produkte zu drucken, verfährt man in der Weise, daß man sie entweder mit oder ohne Reduktionsmittel unter Zusatz von Alkalien druckt und hierauf dämpft oder daß man sie mit einem Reduktionsmittel ohne Zusatz von Alkali druckt und hierauf durch Alkali passiert.In order to print the products, one proceeds in such a way that one either uses them or prints without reducing agents with the addition of alkalis and then steams or that they are printed with a reducing agent without the addition of alkali and then through Alkali happens.
