  zusatzpatent     zun,    Hauptpatent     Nr.   <B>86851.</B>    Verfahren     ztir    Herstellung eines neuen     ehronderbaren        Orthooxyazofarbstoftes.       Es wurde gefunden,     dass    man durch Kup  peln von     diazotiertein        5-Nitt-o-2-aiiiiiio-l-oxy-          benzol    mit der     N-Methylens(ilfo",#i'i(ii-e    der       2-Aminonaplitaliii-6-sulfosätire    einen neuen       ehromierbaren        Orthooxyazofarbstoff    herstellen  kann.

   Dieser Farbstoff bildet ein dunkelvio  lettes Pulver und färbt Wolle     atis    saurein  Bade in     blaustiebig        bordeatixpoten    Tönen an,  welche beim     Nachehromieren    in ein     grün-          stichiges    Blatt von guter     Walk-    und     PottIng-          echtheit    Übergehen.

  additional patent, main patent no. <B> 86851. </B> Process for the production of a new special orthooxyazo dye. It has been found that coupling diazotized 5-Nitt-o-2-aiiiiiio-l-oxybenzene with the N-methylene (ilfo ", # i'i (ii-e of 2-aminonaplitaliii-6- sulfosätire can produce a new honorable orthooxyazo dye.

   This dye forms a dark purple powder and dyes wool atis acidic bath in blue-tinged, bordeatix-like shades, which, when retouched, turn into a green-tinged sheet of good milled and potty-fastness.

      <I> Example: </I> 15.4 <B> kg </B> 5-Niti-o-2-amiiio-l-oxybeiivol would with <B> 30 kg </B> hydrochloric acid from <B> 30 '' / o </B> and <B> 712 </B> kg of technical sodium nitrite as usual dia7.0-. The Diazolz;

  The solution is allowed to run <B> in </B> a solution of <B> 32 kg </B> N-methylene "tilfosäuire of 2-Aminoiiaphtalin-6-stilfosäuti # e (represented by the action of formaldehyde and sodium bistilfit on 2- aniiiioiial) htaliii-6-s (ilfosaures Natron) lgeli ') st in <B> 100 </B> liters of water. The coupling is completed within a few hours at a certain temperature, in which the salt is removed by salting out, decided.
