  Process for the production of an azo dye containing complexed cobalt ". It has been found that a complex g iun:

  denes cobalt-containing azo dye L can be produced if the by exposure to the azo dye of the formula
EMI0001.0011
         the Izo dye obtained with sulfonating agents until the entry of an additional sulfonic acid group is treated with agents that donate cobalt.



  The new cobalt compound is a very black powder that dissolves in water with yellow-brown, 10% sodium hydroxide solution, as well as 10% sodium hydroxide solution with brown-red color and in concentrated sulfuric acid with blackish-red color, and animal fibers in real brown tones colors.



  The azo dye containing two sulfonic acid groups and containing two sulfonic acid groups can be obtained by adding 10 parts of the azo dye prepared by alkaline coupling from diazotized 4-chloro-2-amino-1-oxybenzene-6-sulfonic acid and 5-aminoperinaphthindanedione below 1.0 in 100 parts of fuming sulfuric acid, the 2,

  Contains 4% SO3, heated to 95 to 100 for 8 hours, the reaction mixture poured onto 400 parts of ice, heated to 40, filtered and the dye separated from the solution by adding sodium chloride.



  <I> Example: </I> 52.5 parts of the azo dye containing two sulfonic acid groups, which is produced by alkali coupling of diazotized 4-chloro-2-amino-1-ogybenzene-6-sulfonic acid and 5-aminoperinaphthindanedione and the following Treatment with sulfonating agents was made,

   are dissolved in <B> 1000 </B> parts of water and heated to boiling for 10 minutes with a solution of 31 parts of crystallized cobalt sulfate in <B> 150 </B> parts of water. After this time, the azo dye has completely converted into its cobalt compound. This is obtained by adding table salt, filtering and drying
