  Process for the preparation of monoazo dyes for wool.
 EMI1.1
 black milled and lightfast wool dyes by combining diazotized 5-nitro- -2-aminophenol ethers with aryl-2.8-aminouaphthol-6-sulfonic acid in acidic solution.



   It has now been found that dyes with very similar properties are obtained if the 5-nitroaminophenyl ethers are replaced by other unsulfated nitroamino-

    Example 10 138 parts of o-nitroaniline are diazotized as usual. The excess acid will

 violet of high lightfastness.



   If the o-nitroaniline is replaced by a derivative such as 2-nitro-4-acetphenylenediamine and the phonyl-2. 8-aminonaphthol-6-sulfonic acid by tolyl- or anisidyl-2,6-aminonaphthol-sulfonic acid, etc., the properties remain essentially the same.
