Die Farbsalze eignen sich vorzüglich für die Spinnfärbung von Polyacrylnitril. Man erhält rot gefärbte transparente Fasern mit ausgezeichneter Echtheit. Color salts of the formula in which A is the residue of a carbocyclic or heterocyclic aromatic diazo component, RH, optionally substituted alkyl, alkenyl, cycloalkyl, phenalkyl or phenyl, Z optionally substituted alkylene, R 1 and R 2 alkyl, R 3 alkyl, cycloalkyl, hydroxyalkyl or aralkyl or in which R 1 , R 2 and R 3 together with the intermediate N atom form a heterocyclic ring, XH, halogen, alkoxyl, alkyl, YH, halogen, alkyl, alkoxy or alkanoylamino, where, if A is the residue of a heterocyclic diazo component, R 1 , R 2 and R 3 together with the N atom in between form a heterocyclic ring. The color salts are ideal for spin dyeing polyacrylonitrile. Red colored transparent fibers with excellent fastness are obtained.
