Abstract
Dyes of formula (1) wherein Z is C10-C20terpeneamino; or N-mono- or N,N-di-C1-C16alkylamino unsubstituted or substituted in the alkyl moiety by phenyl (which may itself be substituted by carboxy, carbamoyl, sulfo or by sulfamoyl), amino, C2-C4alkanoylamino, hydroxy, sulfo, sulfato, carboxy, carbamoyl or by sulfamoyl, which further may be interrupted in the alkyl moiety by one, two or three oxygen atoms or —NH— groups, yield bluish magenta prints and dyeings having good light-fastness properties and a high colour brilliance.
