  <B> Additional patent </B> to main patent no. 245067. Process for the production of a substantive azo dye. The subject of the present addendum, patent is a process for the production of a substantive azo dye, characterized in that one .diazotized CTemis6h from.

   1 mol each of 1-oxy-2'-aminobenizole-4-carbonic acid-p'henylamide and 1-oxy-2-amino-b, enzene-6 = chloro-4-sulfonic acid with 1 mol of the symmetrical urea, from 2 -Amino-5,

  - Oxynaphtha! lin-7-sulfous acid combined in afkalisidhem medium and the new Fambatoff converted into a complex copper compound by treatment with copper-releasing agents. This dyes cotton in real red-purple tones.



  <I> Example: </I> 2'2.8 parts by weight of 1-oxy-2-aminobenzene-4-carboxylic acid phenyl.amide and 2'3.3 parts by weight of 1-oxy-2-aminob @ enizol- @ 6i- ühI; or-4-:

  su-Ifonic acid with the addition of 14 parts by weight of sodium nitrite and b6 parts by weight of concentrated hydrochloric acid are diazotized at 0, and the diaizo compound with 5'0.4 parts by weight of the symmetrical urea is made from 2 @ amino-5-oxyna] ythalene-7 -sulfonic acid,

      that as sodium salt with the addition of 20.0 parts by weight of 20% i: according to calcium hydroxide: in 2000 parts by weight of water;

  were dissolved, combined. After 4 hours, the dye formed is separated off by adding hydrochloric acid and filtered. The filter residue is treated in a known manner by treating with a solution of 5 parts by weight of crystallized copper sulfate in 200 <RTIgt;

   ID = "0001.0080"> parts by weight of 25% ammonia in 2000 parts by weight of water ei 3: 5-40 into its copper compound! The formed copper compound precipitates, is filtered and net getrock. The new dye forms a dark powder that dyes cotton in similar red-violet tones.
