  <B> Additional patent </B> to main patent no. 261125. 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 by that one.

   1 mol of the tetrazo compound of 1- (3 '.- Amino-4'-oxy-benzoyiamino) -4-aminobenzene-3-carboxylic acid on the one hand with 1 mol of 1- (4'-aminophenyl) -3 - phenyl-5-pyrazolone and on the other hand with 11o1 1- (4'-Amino-3'-sulfo-plienyl) -3-methyl-5-pyrazolone couples.



  The new disazo dye obtained is a dark brown powder, which in water with yellow-brown and in conc. Sulfur acid with a yellow color dissolves and stains fibers made from natural or regenerated cellulose after copper-plating in yellow-brown tones, which have excellent fastness properties.

      <I> Example: </I> 28.7 parts of 1- (3'-amino-4'-oxy-benzoyl-amino) -4-amino-benzene-3-carbonsätire are in 400 parts of water with 8 parts of sodium hydroxide solution dissolved cold, mixed with 13.8 parts of sodium nitrite and concentrated in the cold with stirring to 40 parts. Hydrochloric acid and 80 parts of water were added dropwise. After the excess mineral acid has been blunted with sodium bicarbonate, the tetrazo compound is combined with 25.1 parts of 1- (4 'A.mino-phenyl) -3-phenyl-5-pyrazolone,

   dissolved in 200 parts of water and 20 parts of sodium bicarbonate. An aqueous solution of 26.9 parts of 1- (4'-amino-3'-sulfo-phenyl) -3-methyl-5-pyrazolone, 20 parts of soda and 150 parts of pyr- idin flow. After several hours of stirring at room temperature, the disa.zo dye formed is of the formula
EMI0001.0044
