  <B> Additional patent </B> to main patent no. 245067. Process for the production of a noun azo dye. The subject of the present additional patent is a process for the production of a s.ubstantive azo dye, because imane denotes the diazotized mixture of 1 mole of 1-oxy-, 2-aminab, enzol-4-oarbonic acid-pheny,

  Iamide and 1-oxy = 2'-aminobenzene-6-chloro-4-sulfonic acid with 1 mol: l 5,5'-dioxy-2,2'-d, inaphthylamine-7,7 '- @ disulfonic 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> 22.8 parts by weight 1-Oxy-2 @ aminobenizo1-4-carbo @ ns5, urephenylamide and 22 1.31 parts by weight 1-Oxy-2-aminobenzene-6-chloro-4 - Sulfonic acid are diazotized at 0 with the addition of 14 parts by weight of sodium nitrite and 54 parts by weight of concentrated hydrochloric acid and, the mixed Dia.zoverbindun,

  g with. 46.1 parts by weight of 5,5'-dioxy-2,2'-dinaphthyl-a.min-7,7'-disulf, onic acid, which as. Sodium salt with the addition of 200 parts by weight of 20% calcium hydroxide was dissolved in 200: 0 parts by weight of water, combined.

           After 4 hours, the dye formed is deposited by adding hydrochloric acid and filtered. The filter residue is treated in a known manner by treating with a solution of 510 parts by weight of crystallized copper sulfate in 200 parts by weight of 2t5% ammonia in 200:

  0 parts by weight of water at 35 ° 40% converted into its copper compound. The copper compound formed precipitates, is filtered and dried. The new dye forms a dark powder that dyes cotton in real blue-violet tones.
