  <B>Zusatzpatent</B> zum Hauptpatent Nr. 110287.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man die     3-Oxynaph-          thalin-1,8-dikarbonsäure    mit     diazotierter    4  Chlor-2-a.mino-1=phenol-6-sulfosäure kuppelt  und den so erhaltenen Farbstoff mit     Alkali-          chromit    behandelt. Der neue     Farbstoff    bil  det ein schwärzliches Pulver, löst sich in  Wasser     unter    Zusatz von Natronlauge mit  rotvioletter Farbe und erzeugt im Chrom  ,druck auf Baumwolle sehr echte violette  Töne.  



       Beispiel:     22,3 Teile     4-Clilor-2-,amino-l-ph@enol-6-          sulfosäure    werden wie üblich     diazotiert    und  in eine Lösung von     21.,6    Teilen     3-Oxynaph-          thalin-1,8-dik        @anbons.äureanhydrid,    8 Teilen  Natronlauge und 40 Teilen Soda in 500 Tei  len     Wasser    eingetragen. Man rührt, bis die       Diazoverbindung    verschwunden ist. Hierauf  salzt man mit     go:chsalz    aus und filtriert     Iden     ausgeschiedenen Farbstoff.  



  26,7 Teile dieses Farbstoffes werden in  eine kochende Lösung, enthaltend 8,5 Teile         Cr-#Os,    100 Teile Wasser, 28 Teile     Ätzkali     und 10 Teile Glyzerin eingetragen und län  gere Zeit gekocht. Nach dem     Verdünnen    mit  zirka 200 Teilen Wasser wird filtriert und  aus dem Filtrate der neue Farbstoff durch  Neutralisieren und     Aussalzen    isoliert.



  <B> Additional patent </B> to main patent no. 110287. Process for the production of a new dye. It has been found that a new dye is obtained if the 3-oxynaphthalene-1,8-dicarboxylic acid is coupled with diazotized 4-chloro-2-a.mino-1 = phenol-6-sulfonic acid and the dye thus obtained is coupled with it Treated with alkali chromite. The new dye forms a blackish powder, dissolves in water with the addition of caustic soda with a red-violet color and produces very real violet tones in the chrome print on cotton.



       Example: 22.3 parts of 4-Clilor-2-, amino-l-ph @ enol-6-sulfonic acid are diazotized as usual and converted into a solution of 21.6 parts of 3-oxynaphthalin-1,8-dik @ Anbons.äureanhydrid, 8 parts of sodium hydroxide solution and 40 parts of soda in 500 parts of water entered. Stir until the diazo compound has disappeared. It is then salted out with salt and the precipitated dye is filtered off.



  26.7 parts of this dye are added to a boiling solution containing 8.5 parts of Cr- # Os, 100 parts of water, 28 parts of caustic potash and 10 parts of glycerol and boiled for a longer time. After dilution with about 200 parts of water, the mixture is filtered and the new dye is isolated from the filtrate by neutralization and salting out.
