  Zusatzpatent     züm    Hauptpatent     Nr.    130428    Verfahren zur Darstellung eines     Nüpenfarbstoffes.       Nach dem Hauptpatent     Nr.    130428     ge-          eD          lf,no#t    man zu einem neuen     Käpenfarbstoff,          t'     wenn man ein     real#tionsf'Ihi-#es        a-Derivat          kl     des 4.

       6-Dimetliyl-5-7-dielilorisatins    wie       züm    Beispiel das     a-Chlorid    und     4-Chlor-1.-          Naphtol    aufeinander einwirken     hisst.     



  Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines neuen       Küpenfarbstoffes,    dadurch gekennzeichnet,  <B>Z</B>       dass    man     ein    reaktionsfähiges     (Y-Derivat    des       5-6-Dieblor-7-1#lethylisatins    und     5-Chlor-i-          iiieth,#7-1-3-0-,#ythior.aphten    aufeinander ein  wirken     lässt.     



  Der neue Farbstoff     stelit    trocken ein       violettblaues    Pulver     dar.    Er färbt die Faser  aus     rotstichio,          --olduelber        Küpe    in etwas       zn    en     tD     marineblauen Tönen an.  



  <I>Beispiel:</I>  <B>23</B>     Gewiehtsteile   <B>5</B>     .6-Diehlor-7-methyli-          satin    werden in etwa<B>250</B> Gewichtsteilen  Chlorbenzol suspendiert und nach Zusatz von       ')")    Gewichtsteilen     Phosphorpentachlorid    bis  zur Lösung erwärmt.

   Die entstandene Lösung       lässt    man in eine Lösung von<B>19 . 9</B> Ge-         wichtsteilen        5-Chlor-7-methyl-3-oxytllionaph-          tpn    in<B>9-00</B>     Gewichtsteilen    Chlorbenzol ein  laufen, wobei sich der 5-Clilor-7-methyl-2       tliionaphten-5'-6'-dichlor-7'-mei-Ilyl-2'-indo-          linindigo    sofort abscheidet. Nach kurzem  Erwärmen bei<B>80-90 ' C</B> wird der Farb  stoff     ültriert,    mit Chlorbenzol und dann mit  Alkohol gewaschen und dann getrocknet.

    Er besitzt     eine'violettblaue    Eigenfarbe und  färbt die Faser aus goldgelber     Küpe    in  etwas     rotstichigmarineblauem    Farbton an.



  Additional patent to the main patent No. 130428 Process for the preparation of a pimple dye. According to the main patent no. 130428 ge eD lf, one no # t to a new cap dye, t 'if one real #ationsf'Ihi- # es a derivative kl of the 4th

       6-Dimetliyl-5-7-dielilorisatins as for example the a-chloride and 4-chloro-1.- naphthol interact.



  The subject of the present patent is a process for the production of a new vat dye, characterized in that a reactive (Y-derivative of 5-6-Dieblor-7-1 # lethylisatin and 5-chloro-i- iiieth, # 7-1-3-0 -, # ythior.aphten affect each other.



  The new dye is a violet-blue powder when dry. It stains the fiber from red stichio, gold-colored vat in somewhat zn and tD navy blue tones.



  <I> Example: </I> <B> 23 </B> parts by weight <B> 5 </B> .6-Diehlor-7-methyli-satin are suspended in about <B> 250 </B> parts by weight of chlorobenzene and after adding ') ") parts by weight of phosphorus pentachloride heated until dissolved.

   The resulting solution is immersed in a solution of <B> 19. 9 parts by weight of 5-chloro-7-methyl-3-oxytllionaphthene run into 9-00 parts by weight of chlorobenzene, the 5-chloro-7-methyl-2-thiionaphthene -5'-6'-dichloro-7'-mei-Ilyl-2'-indoline indigo separates immediately. After briefly heating at <B> 80-90 'C </B>, the dye is filtered, washed with chlorobenzene and then with alcohol and then dried.

    It has a violet-blue inherent color and dyes the fiber from the golden-yellow vat in a slightly reddish-tinged navy blue shade.
