      Zusatzpatent    zum     Hauptpatent    Nr. 205164.    Verfahren zur Herstellung eines neuen Derivates eines     Azofarbstoffes.       Es wurde gefunden, dass man ein neues  Derivat eines     Azofarbstoffes    erhält, wenn man  1     Mol    des     Pentakisazofarbstoffes,    der erhalten  wird durch Vereinigen eines Moleküls     1,3-          Diaminobenzol    mit je einem Molekül des  dianotierten     Disazofarbstoffes    aus dianotierter       2-Aminonaphthalin-4,8-disulfonsäure    und     1-          Amino-3-methylbenzol,

          Weiterdiazotieren    und  Vereinigen mit einem zweiten Molekül     1-          Amino-3-methylbenzol    und einem Molekül  des dianotierten     Monazofarbstoffes    aus diano  tierter     2-Aminonaphthalin-4,8-disulfonsäure     und     1-Naphtylamin,    mit 2     Mol        Benzoylchlorid     in Gegenwart einer tertiären Base     acyliert.     



  Der neue     Farbstoff    stellt ein gelbbraunes  Pulver dar und färbt Baumwolle in echten  gelbbraunen Tönen.    <I>Beispiel:</I>    1,1 Teil des     Pentakisazofarbstoffes,    der  erhalten wird durch Vereinigen eines Mole  küls     1,3-Diaminobenzol    mit je einem Molekül    des dianotierten     Disazofarbstoffes    aus     diazo-          tierter        2-Aminonaphthalin-4,8-disulfonsäure     und     1-Amino-3-methylbenzol,

          Weiterdiazo-          tieren    und Vereinigen mit einem zweiten       Molekül        1-Amino-3-methylbenzol    und einem  Molekül des dianotierten     Monazofarbstoffes     aus dianotierter     2-Aminonaphthalin-4,8-disul-          fonsäure    und     1-Naphtylamin    wird in 5 Teilen       Pyridin    suspendiert und bei 400 mit 1,68  Teilen     Benzoylchlorid    versetzt. Man erwärmt  allmählich auf 90   und hält diese Temperatur  eine Stunde.

   Nach dieser Zeit wird das     Di-          benzoylprodukt    abgeschieden und getrocknet.



      Additional patent to main patent no. 205164. Process for the production of a new derivative of an azo dye. It has been found that a new derivative of an azo dye is obtained if 1 mole of the pentakisazo dye obtained by combining one molecule of 1,3-diaminobenzene with one molecule of the dianotated disazo dye from dianotated 2-aminonaphthalene-4,8-disulfonic acid and 1- amino-3-methylbenzene,

          Further diazotization and combining with a second molecule of 1-amino-3-methylbenzene and a molecule of the dianotized monazo dye from diano-tated 2-aminonaphthalene-4,8-disulfonic acid and 1-naphthylamine, acylated with 2 moles of benzoyl chloride in the presence of a tertiary base.



  The new dye is a yellow-brown powder and dyes cotton in real yellow-brown tones. <I> Example: </I> 1.1 part of the pentakisazo dye, which is obtained by combining one molecule of 1,3-diaminobenzene with one molecule each of the dianotated disazo dye from diazotated 2-aminonaphthalene-4,8-disulfonic acid and 1-amino-3-methylbenzene,

          Further diazo- tate and combine with a second molecule of 1-amino-3-methylbenzene and a molecule of the dianotized monazo dye from dianotized 2-aminonaphthalene-4,8-disulfonic acid and 1-naphthylamine is suspended in 5 parts of pyridine and at 400 with 1 , 68 parts of benzoyl chloride were added. The temperature is gradually increased to 90 and this temperature is maintained for one hour.

   After this time, the dibenzoyl product is separated out and dried.
