  Zusatzpatent     züm    Hauptpatent     Nr.   <B>86026.</B>    Verfahren zur Herstellung eines zum     Bauinwolldruck    besonders geeigneten       Azofarbstoffes.       Es wurde gefunden,     dass    man durch Kup  peln von     diazotierter        4-Clilor-2-amino-l-oxy-          benzol-6-earbonsäure    mit     1-Oxyiiaphtalin-3-          sulfo-6-earbonsäure    einen     Azofarbstoff    erhält,  welcher sich in Wasser mit blauroter, in kon  zentrierter Schwefelsäure mit blauvioletter  Farbe löst     und    auf Baumwolle,

   nach dem  Chromdruckverfahren bedruckt, seifen-,     chlor-          und    lichtechte violette Töne gibt.  



  <I>Beispiel:</I>  Die auf bekannte Art aus<B>18,7</B> Teilen  4 -Chlor- 2     -amino-   <B>1</B>     -oxybenzol-   <B>6</B>     -carbonsäure     dargestellte     DiazovIerbindung    gibt man unter  Rühren     züi    einer möglichst konzentrierten  Lösung von<B>29</B> Teilen des     Mononatriumsalzes     der     1-Oxynaphtalin-3-stilfo-6-earbonsäure,    40  Teilen Soda und<B>26</B> Teilen Natronlauge a         30        %.        Der        kristallinisch        ausfallende        Farbstoff     wird kalt filtriert,

       gepresst    und getrocknet.



  Additional patent to main patent no. <B> 86026. </B> Process for the production of an azo dye particularly suitable for building wool printing. It has been found that by coupling diazotized 4-chloro-2-amino-1-oxybenzene-6-carboxylic acid with 1-oxyiiaphthalene-3-sulfo-6-carboxylic acid, an azo dye is obtained which turns purple in water , dissolves in concentrated sulfuric acid with a blue-violet color and on cotton,

   Printed using the chrome printing process, gives soap, chlorine and lightfast violet tones.



  <I> Example: </I> The known way from <B> 18.7 </B> parts 4 -Chlor- 2 -amino- <B> 1 </B> -oxybenzene- <B> 6 </ The diazo compound represented by the B> -carboxylic acid is added, with stirring, to a solution as concentrated as possible of 29 parts of the monosodium salt of 1-oxynaphthalene-3-stilfo-6-carboxylic acid, 40 parts of soda and 26 parts / B> Parts of sodium hydroxide solution a 30%. The crystalline precipitating dye is filtered cold,

       pressed and dried.
