   Die gebildete Kupferverbindung     fällt     aus, wird filtriert und     getrocknet.    Der neue  Farbstoff bildet ein dunkles Pulver, das       Baumwolle    in     echten        blauvioletten    Tönen  färbt.



  Additional patent to main patent No. 245067. Process for the production of a substantive azo dye. The subject of the present additional patent is a process for the production of a substantive azo dye, characterized in that 2 mol of diazotized 1.-oxy-2.-aimino'b: enzene-4-carboxylic acid-phenyl-ami-d .mit 1 mole of 5,5'-dioxy-2 :;

  2 ', dina @ ethyl amine-7,7' -, dssulfonic acid combined in an alkaline medium and the new dye converted into a complex copper compound by treatment with copper-releasing agents. This dyes cotton in real blue-violet tones.



  <I> Example: </I> 45.6 parts by weight of 1-Oxy.2-a@minobenzene- 4-carboxylic acid phenylamide are diazotized with the addition of 14 parts by weight of sodium nitrite and 54 parts by weight of concentrated hydrochloric acid at 0 and the diazo compound with 46, 1 part by weight of 5,5'-dioxy-12;

  , '2'-Dinaphthylamine-7,7' - @ disu, ifonic acid, which as sodium salt with the addition of 200 parts by weight, en 20 5, 'ig em calcium hydroxide in 2,000 parts by weight of water were dissolved, combined. After 4 hours, the dye formed is deposited by adding hydrochloric acid and filtered.

   The filter residue is converted into its copper sulfate in a known manner by treatment with a solution of 50 parts by weight of crystallized copper sulfate in 200 parts by weight of 215% ammonia in 2000 parts by weight of water at 315-40.

   The copper compound formed precipitates, is filtered and dried. The new dye forms a dark powder that dyes cotton in true blue-violet tones.
