Description

  

  Neues     Farbstoffpräparat    und Verfahren zu dessen Herstellung.    Die symmetrischen 1,2- und     2,1-Naphth-          thioindigos    sind in der Literatur als braune       Küpenfarbstoffe    beschrieben. Näheres über  diese Verbindungen, die bis     anhin    keine Han  delsprodukte waren, ist nicht bekannt. Der       1,2-Napht-htliioindigo    färbt ein Rotbraun, der       29,1-Na-phtlithioindigo    ein gelberes Braun.  



  Es wurde nun gefunden,     dass,    wenn man  diese     Verbindun-,eii    untereinander mischt, und  zwar entweder durch mechanisches Zumischen  oder durch Oxydieren der Lösungen der be  treffenden     Leukoverbindungen    oder der Ge  mische der entsprechenden     Oxythionaphthen-          derivate,    neue Produkte erhalten werden, die  aus der     Küpe    die Faser in braunen Tönen  färben, deren Ergiebigkeit und Lebhaftigkeit  das, was aus, den Färbungen der einzelnen  Komponenten zu erwarten war, ganz     wesent-          lieh    überragen.

   Die erzielte Wirkung ist be  reits bemerkbar, -wenn     weni-e    Prozente des  einen     Fä.rbstoffes    zum andern gegeben wer  den.  



  Gegenstand des vorliegenden Patentes ist  nun ein     Farbstoffpr#Lparat,    welches, aus einer    mechanisch hergestellten Mischung von     sym-          metrischein        1,2-Naphthihioindigo    mit symme  trischem     '-),1-Naphththioindigo    besteht, sowie  ein Verfahren zu dessen Herstellung.    <I>Beispiel:</I>  <B>30</B> Teile     1,2-Naphththioiiidigo    werden mit  <B>70</B> Teilen     2,1-Na.phththioindigo    in einem<B>ge-</B>  eigneten Apparat vermischt.

   Das erhaltene  Produkt färbt aus der     Küpe,    Baumwolle in  rotbraunen Tönen, die den Tönen des reinen       1,2-Na.I)hththioindigos    im Farbton ähnlich,  jedoch ganz bedeutend reiner und voller sind.  



  Ähnliche Produkte werden erhalten, wenn  man     da.s    Mischungsverhältnis nach der einen  oder andern Seite verschiebt. Die Färbungen  sind mit     Hydrosulfit        ätzbar.  



  New dye preparation and process for its production. The symmetrical 1,2- and 2,1-naphthioindigos are described in the literature as brown vat dyes. No further details are known about these compounds, which were previously not commercial products. The 1,2-naphthi-htliioindigo colors a red-brown, the 29,1-Na-phtlithioindigo a more yellow brown.



  It has now been found that if you mix these compounds, eii with each other, either by mechanical admixture or by oxidizing the solutions of the leuco compounds in question or the mixtures of the corresponding oxythionaphthenic derivatives, new products are obtained from the Vat dye the fiber in brown tones, the productivity and liveliness of which surpass what was to be expected from the coloration of the individual components.

   The effect achieved is already noticeable when a few percent of one dye is added to the other.



  The subject matter of the present patent is a dye preparation which consists of a mechanically produced mixture of symmetrical 1,2-naphthioindigo with symmetrical 1-naphthioindigo, as well as a process for its production. <I> Example: </I> <B> 30 </B> parts 1,2-naphththioiiidigo are mixed with <B> 70 </B> parts 2,1-Na.phththioindigo in a <B> ge - </ B> mixed with suitable apparatus.

   The product obtained from the vat dyes cotton in red-brown tones, which are similar in color to the tones of the pure 1,2-Na.I) ththioindigo, but are considerably purer and fuller.



  Similar products are obtained if one shifts the mixing ratio to one side or the other. The colorations can be etched with hydrosulfite.
