  Zusatzpatent     zum    Hauptpatent     Nr.   <B>110287.</B>    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man die     3-Oxytiaph-          thalin-1,8-dikarbonsäure    mit     diazotierter        4-Me-          thyl-2-amitio-l-phenol-6-sulfosätii,e    kuppelt und  den so erhaltenen Farbstoff mit     Chromformiat     behandelt.

   Der neue Farbstoff bildet ein  schwärzliches Pulver, löst sich in Wasser  unter Zusatz von Natronlauge mit rotvioletter  Farbe und erzeugt im Chromdruck auf Baum  wolle sehr echte violette Töne.    <I>Beispiel:</I>  <B>25</B> Teile     4-Methyl-2-amino-l-phenol-6-sulfo-          säure    werden wie üblich     diazotiert    und in  eine Lösung von<B>21,6</B> Teilen     3-Oxynaphtbaliii-          1,8-dikarbonsäureanhydrid,   <B>8</B> Teilen     Natron-          lange    und 40 Teilen Soda in<B>500</B> Teilen  Wasser eingetragen. Man rührt, bis die     Diazo-          verbindung    verschwunden ist.

   Hierauf salzt       man    mit Kochsalz aus und filtriert den aus  geschiedenen Farbstoff.    <B>25,6</B> Teile dieses     Farbstoffes    werden in  <B>500</B> Teilen Wasser heiss gelöst Lind mit einer       Chromformiatmenge,    entsprechend 12,5 Teilen       C'r20s,    versetzt. Man kocht einige Zeit und  filtriert den durch     Kochsalzzusatz    abgeschie  denen Farbstoff.



  Additional patent to main patent no. <B> 110287. </B> Process for the production of a new dye. It has been found that a new dye is obtained if the 3-oxytiaphthalene-1,8-dicarboxylic acid is coupled with diazotized 4-methyl-2-amitio-1-phenol-6-sulfosätii, e and the like obtained dye treated with chromium formate.

   The new dye forms a blackish powder, dissolves in water with the addition of caustic soda with a red-violet color and creates very real violet tones when printed with chrome on cotton. <I> Example: </I> <B> 25 </B> parts of 4-methyl-2-amino-1-phenol-6-sulfonic acid are diazotized as usual and converted into a solution of <B> 21.6 Parts 3-Oxynaphtbaliii- 1,8-dikarbonsäureanhydrid, <B> 8 </B> parts of long soda and 40 parts of soda in <B> 500 </B> parts of water. Stir until the diazo compound has disappeared.

   It is then salted out with common salt and the dye which has separated out is filtered off. <B> 25.6 </B> parts of this dye are dissolved in <B> 500 </B> parts of hot water and an amount of chromium formate corresponding to 12.5 parts of C'r20s is added. It is boiled for some time and the dye separated by the addition of common salt is filtered off.

<B>PATENTANSPRUCH:</B> Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man die S-Oxynaphthalin-1,8-dikarbonsätire mit di- azotierter 4-Methyl-2-amino-l-phenol-6-sulfo- säure kuppelt Lind den so erhaltenen Farb stoff mit Chromformiat behandelt. Der neue Farbstoff bildet ein schwärzliches Pulver, löst ,sich in Wasser unter Zusatz von Natronlauge mit rotvioletter Farbe und ei-zeugt im Chrom druck auf Baumwolle sehrechte violette Töne. <B> PATENT CLAIM: </B> Process for the preparation of a new dye, characterized in that the S-oxynaphthalene-1,8-dicarboxylic acids are mixed with azotized 4-methyl-2-amino-1-phenol-6-sulfo - Acid couples and the dye obtained is treated with chromium formate. The new dye forms a blackish powder, dissolves, dissolves in water with the addition of caustic soda with a red-violet color and, in the chrome print on cotton, creates vertical violet tones.
