  Process for the preparation of an azo dye containing complexed chromium% s. It has been found that an azo dye containing complex bound chromium can be produced if the azo dye of the formula ## STR3 ## which is treated by Be
EMI0001.0005
    monosulfonated azo dye obtained with sulfonating agents until a sulfonic acid subgroup has entered: is treated with chromium-releasing agents.



  The new chromium compound is a brownish-gray powder: which dissolves in water and in 1.0% solo solution with red-orange, in 10% sodium hydroxide solution with red-brown and in concentrated sulfuric acid with a reddish-yellow color and. Dyes leather in red-brown shades with very good fastness properties.



  The monosulfonated azo dye used as the starting material for the process can be obtained by adding 19.5 parts of the azo dye from diazotized 2-amino-benzene-1-: carboxylic acid and 5-nitroperinaphth- in: dandione below 20 'in 120 parts of fuming sulfuric acid, :

Treatment with chromium-releasing agents is carried out according to the known methods, for example by heating in an aqueous medium with salts:

  of trivalent chromium. <I> Example: </I> 47 parts of the monosulfonated azo dye from diazotized 1-aminobenzene -? - ca- rbonic acid and 5 - nitroperinaphthindanedione are dissolved in 1000 parts of water and mixed with a fluorochrome solution containing 9.1 parts of CrA , Heated to the boil for 24 hours. Insoluble matter is then filtered
