Nach dem Aussalzen mit Natriumchlorid und der Trocknung erhält man einen Farbstoff, der Baumwolle in echten goldgelben Nuancen färbt und der Formel entspricht.After salting out with sodium chloride and drying, a dye is obtained that dyes cotton in real golden-yellow shades and has the formula is equivalent to.

Weitere erfindungsgemäße Farbstoffe sind in Tabelle 2 aufgeführt. In Spalte I ist die anstelle von 2-Aminonaphthalin-3,6,8-trisulfosäure verwendete Diazokomponente, in Spalte II das anstelle von Cyanurchlorid verwendete Acylierungsmittel und in Spalte III das anstelle von 4,4'-Diaminodiphenyl-2,2'-disulfonsäure verwendete Diamin aufgeführt.Further dyes according to the invention are listed in Table 2. In column I is the one used instead of 2-aminonaphthalene-3,6,8-trisulfonic acid Diazo component, in column II the acylating agent used instead of cyanuric chloride and in column III that used instead of 4,4'-diaminodiphenyl-2,2'-disulfonic acid Diamine listed.
