Description

  

  Verfahren zur Herstellung einer     Farbstoffmischung.       Es wurde gefunden, dass Farbstoff  misehungen, die     einerseits    Farbstoffe der       Dibenzanthron-    und     Iso,dibenzanthronreihe,     anderseits Farbstoffe enthalten, die durch  Einwirkung alkalischer Mittel auf     Poly-          anthraehinonylaminobenzanthrone    he     bestellt     sind, die     einen        Anthrachinonylaminrest    in  der     Bzl-,Stellung    enthalten, zur     Herstellung     von besonders wertvollen Schwarztönen ge  eignet sind.

       -Die    hiermit erhaltenen Färbun  gen und Drucke ergeben volle schwarze Töne  von vorzüglichen     Echtheitseigenschaften,    ins  besondere zeigen sie gute     wasch-    und Soda  kochechtheit, sowie eine     gesteigerte    Licht  echtheit.  



  Den vorliegenden     Farbstoffmischungen     können gegebenenfalls noch weitere Farb  stoffe     zugemischt    werden. Man     kann    die  Mischung auch erst in der Farbflotte oder  in -der     Druckmasse    entstehen     lassen.     



       Vorliegendes    Patent bezieht sich nun auf  ein Verfahren zur Herstellung einer Farb-         stoffmischung,dadurch    gekennzeichnet, dass  man das alkalische     Kondensationsprodukt     von     Di-(1'-anthrachinonyl)-6-Bzl-diamino-          benzanthron,        erhältlich    aus     6-Bzl-dihalogen-          benzanthron    mit 2     Mol.        1-Amino-anthra-          chinon,        vergl.    Schweizer Patent Nr. 148872.  mit     Indanthrendunkelblau    BOA mischt.  



  Mit dieser     Mischung    erhält man auf  Baumwolle eine     violettstichig    schwarze Fär  bung.  



  <I>Beispiel:</I>  3,6 Teile -des Farbstoffes,     hergestellt     nach     ,Schweizer    Patent Nr. 148.372,     werden     mit 1,8 Teilen des Farbstoffes     Indanthren-          dunkelblau        B0A    (Schultz,     Farbstofftabellen,     7. Auflage,     Nr.1262)    gemischt.



  Process for the preparation of a dye mixture. It has been found that dye misehings, on the one hand dyes of the dibenzanthrone and iso, dibenzanthron series, on the other hand, dyes that are ordered by the action of alkaline agents on polyanthraehinonylaminobenzanthrones that contain an anthraquinonylamine radical in the Bzl-, position, for the production of particularly valuable black tones are suitable.

       The dyeings and prints obtained in this way result in full black tones with excellent fastness properties, in particular they show good washing and soda boiling fastness, as well as increased light fastness.



  If appropriate, further dyes can be added to the dye mixtures present. The mixture can also be created in the dye liquor or in the printing mass.



       The present patent relates to a process for producing a dye mixture, characterized in that the alkaline condensation product of di- (1'-anthraquinonyl) -6-Bzl-diamino-benzanthrone, obtainable from 6-Bzl-dihalo-benzanthrone, is obtained with 2 mol. 1-amino-anthraquinone, cf. Swiss Patent No. 148872. mixed with indanthrene dark blue BOA.



  This mixture gives a purple-tinged black dyeing on cotton.



  <I> Example: </I> 3.6 parts of the dye, produced according to Swiss Patent No. 148.372, are combined with 1.8 parts of the dye indanthrene- dark blue B0A (Schultz, Dye Tables, 7th Edition, No. 1262 )    mixed.
