    Abstract: According to the invention, trisazo dyes are produced by half-side coupling bis-diazotized 4-(4-amino phenylsulfamoyl)aniline to 1-amino-8-hydroxynaphthalene monosulfonic and disulfonic acids, by subsequently coupling diazotized substituted anilines to the other portion of the sulfonic acid, and finally by reacting the second diazonium group on the 4-(4-amino phenylsulfamoyl)aniline with a coupling partner. The inventive trisazo dyes are particularly suited for dying leather and polyamide fibers.
