Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 276120. <B>Verfahren zur Herstellung von</B> trockenen Küpenfarbstoffpräparaten <B>und nach diesem</B> <B>Verfahren hergestelltes Präparat.</B> Gegenstand des Hauptpatentes ist ein Ver fahren zur Herstellung von trockenen Küpen- farbstoffpräparaten durch Trocknen von Farbstoffteigen, die Küpenfarbstoffe in zum Drucken geeigneter Verteilungsform enthal ten, bei welchem man den Teigen vor dem Trocknen alkaliunempfindliche, viskos wasser lösliche Äthercarbonsäuren hochpolymerer Kohlenhydrate bzw.
wasserlösliche Salze der selben in einer Menge zusetzt, die mindestens 101/o das Farbstofftrockengewichtes beträgt, sowie ein nach diesem Verfahren hergestelltes Präparat.
Es wurde nun gefunden, dass man zur Durchführung des im Hauptpatent geschütz ten Verfahrens zweckmässig solche Äthercar bonsäuren hochpolymerer Kohlenhydrate bzw. wasserlösliche Salze derselben verwendet, die sich von Dextrin bzw. von solchen hochpoly meren Kohlenhydraten ableiten, deren Mole külgrösse derjenigen von Dextrin mindestens gleichkommt.
Während die aus Dextrin selbst erhaltenen Äthercarbonsäuren in wässeriger Lösung be reits eine gewisse nicht unerhebliche Viskosität. zeigen und brauchbar sind, ist es zweckmässig, solche Äthercarbonsäuren zu verwenden, deren wässerige Lösungen eine noch höhere Viskosi tät besitzen. Solche Äthercarbonsäuren leiten sich beispielsweise von nicht abgebauter Stärke oder von Cellulose ab.
<I>Beispiel 1:</I> 150 Teile eines wässerigen Presskuchens von 4,5'-Di-(benzoylamino)-1,1'-dianthrimid- carbazol mit einem Trockengehalt von 18,7% werden mit 8 Teilen 50%iger Sulfitablauge bis zur Erreichung der erforderlichen Fein heit in einer Kugelmühle gemahlen.
Nach Zugabe von 18,4 Teilen celluloseglykolsau- rem Natrium in Form einer wässerigen Lösung wird eine weitere Stunde in der Kugel mühle gemahlen und .die entstandene Paste im Zerstäubertrockner getrocknet.
<I>Beispiel 2:</I> 200 Teile eines wässerigen Presskuchens mit einem Gehalt von 15% Indanthron (Schulz- Farbstofftabellen Nr.1228) werden mit 3 Tei len dinaphthylmethandisulfonsaurem Natrium bis zur Erreichung der erforderlichen Fein heit in der Kugelmühle nass gemahlen.
Nach Zugabe von 7,5 Teilen celluloseglykolsaurem Natrium in Form einer wässerigen Lösung und 48 Teilen 50%iger Sulfitablauge wird eine weitere Stunde in der Kugelmühle ge mischt und die entstandene Paste im Zerstäu- bertrockner getrocknet. Das erhaltene Farb- stofftrockenpräparat ist besonders für das Färben nach dem Pigmentverfahren sehr gut. geeignet.
Nach der gleichen Vorschrift kann auch der Farbstoff des vorhergehenden Beispiels verarbeitet werden.
<B> Additional patent </B> to main patent no. 276120. <B> Process for the production of </B> dry vat dye preparations <B> and preparation produced by this </B> <B> process. </B> Subject matter of The main patent is a process for the production of dry vat dye preparations by drying dye doughs that contain vat dyes in a distribution form suitable for printing, in which the dough is mixed with alkali-insensitive, viscous water-soluble ether carboxylic acids of highly polymeric carbohydrates or carbohydrates before drying.
water-soluble salts are added to the same in an amount which is at least 101 / o of the dry weight of the dye, as well as a preparation produced by this process.
It has now been found that in order to carry out the process protected in the main patent, it is advisable to use those ether-carboxylic acids of high-polymer carbohydrates or water-soluble salts thereof, which are derived from dextrin or from those hochpoly meren carbohydrates whose molecular size is at least equal to that of dextrin.
While the ether carboxylic acids obtained from dextrin itself already have a certain not inconsiderable viscosity in aqueous solution. show and are useful, it is advisable to use those ether carboxylic acids whose aqueous solutions have an even higher viscosity. Such ether carboxylic acids are derived, for example, from undegraded starch or from cellulose.
Example 1: 150 parts of an aqueous presscake of 4,5'-di- (benzoylamino) -1,1'-dianthrimide carbazole with a dry content of 18.7% are mixed with 8 parts of 50% strength Sulphite waste liquor ground in a ball mill until the required fineness is achieved.
After the addition of 18.4 parts of sodium cellulose glycol in the form of an aqueous solution, it is ground for a further hour in the ball mill and the resulting paste is dried in an atomizer dryer.
<I> Example 2: </I> 200 parts of an aqueous presscake with a content of 15% indanthrone (Schulz color table No. 1228) are wet-ground with 3 parts of sodium dinaphthylmethanedisulphonic acid until the required fineness is achieved in the ball mill.
After adding 7.5 parts of sodium cellulose glycol in the form of an aqueous solution and 48 parts of 50% strength sulphite waste liquor, the mixture is mixed in the ball mill for a further hour and the resulting paste is dried in an atomizer dryer. The dry dye preparation obtained is particularly good for dyeing by the pigment process. suitable.
The dye of the previous example can also be processed according to the same instructions.
