  Additional patent to main patent No. 138024. Process for the production of a metal-containing azo dye. It has been found that a new metal-containing dye is obtained if one;

  the Ehrom-containing dye, which by treatment of the azo-dye (, - s, from the nitrated 1-diazo-2-oxynaplitlialin-4-su-Ifos # lure and a-naplitliol with chromium formate in the whirlpool and in the presence of sodium acetate arises, treated with copper compounds which are formed by the action of caustic substances on copper salts in the presence of glycerine.



  The new dye is soluble in water with violet, ett, se, liwarzer, in <B> 10 </B>% sodium hydroxide solution with reddish brownish-violet and in concentrated sulfuric acid with blue color. He dyes wool and silk in black tones.



  <I> Example: </I> <B> 50 </B> parts of the dye from the nitrated 1.-diazo # -, -) - oxynaphthalene-4-sulfos # lure and a-NLapht, liol - become, in <B> 600 </B> parts of water with the addition of <B> 7 </B> parts of sodium hydroxide solution <B>30<I>'</I></B> <I> B6 </I> ge n dissolves and with <B> 15 </B> parts of crystal, sodium acetate, and a solution of 21 parts of chromium formate, containing 40 <B>% </B> Cr # A, 1, in <B> 100 </ B> parts of water added. The mixture is refluxed for three hours and filtered.



  An amount of this solution corresponding to <B> 50 </B> parts of the chromium-containing dye is mixed with <B> 30 '</B>, a copper-containing solution of <B> 2.5 </B> parts of crystalline copper sulfate., <B> 15 </B> parts of glycerine, <B> 5 5 </B> parts of sodium hydroxide solution <B> 3.0 '</B> B6 and 400 parts of water are added. It is left to stand overnight, then the partially insoluble a., B # ges # r, hieid, en, eCr-Cu compound is added by adding <B> 30 </B> parts of acetic acid and <B> egg < / B> r- warm to 40 <B> '</B> in solution, filter, salt out and dry as usual.
