  Additional patent to main patent no. <B> 261125. </B> Process for the production of a copperable polyazo dye. The present patent relates to a process for the preparation of a copperable polyazo dye. The process is characterized in that <B> 1 </B> mol of the tetrazo compound of 1- (3'-amino-4'-oxy-benzoylamino)

     <B> - </B> 4 <B> - </B> amino <B> - </B> benzene-3-carboxylic acid on the one hand with <B> 1 </B> mol 2- (4'-oxy- 3'-earboxy-phenylamino) -5-oxy-naphthalene-7-sulionic acid and on the other hand with 1 mol of 2-methoxy-acetic acid. acid anilide coupling.



  The new disazo dye obtained is a brownish-black powder, which looks red in water with purple tinges and in conc. Sulfuric acid with a wine-red color dissolves and stains cellulose fibers in brown tones, which after treatment with copper salts show very good overall strength.

      <I> Example: </I> <B> 28.7 </B> parts of 1- (3'-amino-4-oxy-benzoyl-amino) -4-aminobenzene-3-carboxylic acid are in 400 parts Water with <B> 8 </B> parts of cold sodium hydroxide solution, mixed with <B> 13.8 </B> parts of sodium nitrite and concentrated in the cold with stirring to 40 parts. Hydrochloric acid and <B> 80 </B> parts of water are added dropwise and the excess mineral acid is blunted with soda.

   The tetrazo compound obtained is mixed with 3.7.5 parts of 2- (4'-oxy-3'-earboxy-phenylamino) -5-oxynaphthalene-7-sullonic acid, dissolved in > 300 parts of water in the presence of 20 parts of soda to the one-sided intermediate product and, after coupling is complete, with 20.7 parts of 2-methoxy-aeetacetic anilide and a further addition of 5 Parts of soda combined to disazo dye. The obtained dye of the formula
EMI0001.0037
    is precipitated with table salt, filtered off and dried ge.
