      Additional patent to the main patent No. 245067. Process for adjusting a substantive azo dye. The subject of the present additional patent is a process for the production of a sübstantiven azo dye, characterized in that 2 Mo:

  l Diazotized 1-oxy-2-aminotbenzene-4-earbonic acid-phenylamide combined with 1 mol of the symmetrical urea of 2-amino-5-oxynap: hthalene-7-sulfonic acid in an alkaline medium and, the new dye by treating with copper yellowing:

  en means converted into a complex copper compound. This colors tree walls in real red-violet tones.



       Example: 45.6 parts by weight of 1-oxy-2'-aminobenzene-4-: carboxylic acid phenylamide are dianotized at 0 with the addition of 14 parts by weight of sodium nitrite and 5'4 parts by weight of concentrated hydrochloric acid and the diazo compound with 50.4 parts by weight:

  the symmetrical urea of 2-amino-5-oxynaphthihalin-7-sulphonic acid, which was dissolved in 200.0 parts by weight of water as the sodium salt with the addition of 200 parts by weight of 210% calcine hydroxide.

   After 4 hours: the dyestuff formed is deposited by adding hydrochloric acid and filtered.

   The filter residue is converted into its copper compound in a known manner by treating it with a solution of 5.0 Gewhbs @ tei, 1en crystallized copper sulfate in 2100 parts by weight of 25% ammonia in 21000 parts by weight of water at 35-40.

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