  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 r:

  ai-bstoffes, which consists in the fact that 1 mol of the tetrazo compound from 3,3'-dimethoxy-4,4'-diamino-1,1'-diphenyl with 1 mol of the copper complex compound from the monoazo dye of the composition
EMI0001.0015
         and with 1 mol of 1-phenyl-3-methyl-5-pyrazolone couples and the resulting polyazo dye with splitting of the methoxy groups with a <RTI

   ID = "0001.0022"> treated copper-donating agents. <I> Example: </I> The tetrazo compound from 24.4 parts of 3,3'-dimethoxy-4,4'-diamino-1, 1'-dipheny-1 becomes soda-alkaline with a solution of 63.2 parts the copper complex compound of the monoazo dye of the composition
EMI0001.0031
    in 400 parts of water for intermediate compound 1:

  clumsy. The completely precipitated intermediate is filtered and poured into a solution of 1 T of 1-phenyl-3-methyl-5-pyrazolone iuid 40 parts of soda in 500 parts of water <# et.rayen.



       After completion of the coupling, the trisazo dye is isolated and coppered using the usual demethylating methods.



  When dried, the copper complex compound of the new dye is a dark powder that dissolves blue in both water and concentrated sulfuric acid and dyes cotton in gray tones.
