  Process for the preparation of a complex copper compound of a polyazo dye. It has been found that a complex copper compound of a polyazo dye by the action of copper-releasing,

      as well as alkaline reducing agents to the azo dye of the formula
EMI0001.0009
         bis to link two molecules through the nitrogen bridge created during the reduction of the nitro groups, if the action of the copper releasing and the alkaline reducing agent is carried out without isolating an intermediate product.



  When dry, the copper compound is a dark powder that dissolves in water and concentrated sulfuric acid with a blue color and stains cotton and rayon on regenerated cellulose from a bath containing Glauber's salt in blue tones.



  The action of the copper releasing agent, as well as the alkaline reducing agents, such as. B. glucose, without isolating an intermediate product, is carried out for example in such a way that a solution of the dye in aqueous caustic alkalis, such as.

   B. in sodium or potassium hydroxide, is heated with the metal donating and the redu decorative agent. Example:

       1.7 parts of 5-nitro-2-amino-1-oxybenzene are diazotized and coupled with 4.4 parts of 2- (4'-oxy-3'-carboxy-) phenylamino-5-oxynaphthalene-7-sulfonic acid.

   The dye obtained is deposited, cleaned, dissolved in 2.50 parts of 60 'water with the addition of 24 parts of 30% strength sodium hydroxide solution and treated for about 10 minutes with a copper agent which is made from a solution of 2;

  5 parts of copper sulfate and 3 parts of tartaric acid in 50 parts of water and the amount of sodium hydroxide solution required for neutralization was prepared. Here you add 1.8 parts of glucose as a 10% solution, heat for about an hour to <B> 60 ', </B>; acidify with acetic acid and separate the color by adding table salt.
