  Additional patent to main patent no. 292412. Process for the production of a polyazo dye. The subject of the present patent is a process for the production of a polyazo dye, which consists in that <B> 1 </B> mol of the tetrazo compound from 3,31-dimethoxy-4,4'-diamino-1,1 "-diphenyl with <B> 1 </B> mol of 2-oxynaphthalene-4-si,

  dfonsä-are and with <B> 1 </B> mol <B> 35 </B> of the copper complex compound from the monoazo dye of the composition:
EMI0001.0015
    coupled and treated the polyazo dye obtained after splitting the methoxy group with a copper donor.

      <I> Example: </I> The tetrazo compound from 24.4 parts of 3,3'-dimethoxy-4,4'-diamino-1-, 1'-diphenyl. is coupled in the usual way sodaalkalisell with 22.4 Tei len 2-oxynaphthalene-4-sulfonic acid to inter mediate connection.

   The isolated intermediate compound is entered <B> in </B> a solution of <B> 63.2 </B> parts of the copper complex compound of the mionoazolar material of the composition
EMI0001.0028
         2.50 parts of pyridine and <B> 50 </B> parts of ammonia 2511 / nig in <B> 500 </B> parts of water.

       After the coupling has ended, the trisazo dye is isolated and coppered in a demethylating manner according to the usual methods.



  The copper complex compound of the new dye, when dried, is a dark powder, which dissolves in water as well as in concentrated sulfuric acid with a blue color and dyes cotton in true blue-gray tones.
