Abstract

Trisazo dyes capable of forming metallic complex compounds are made by diazotizing aminodisazo dyes containing 8-aminoquinoline or its nuclear substitution products as end component, and coupling with a further azo component. The following dyestuffs are described: aniline-2 : 5-disulphonic acid or 2-naphthylamine - 4 : 8 - disulphonic acid --> a -naphthylamine --> 8-aminoquinoline --> N-phenyl J acid (blue on cotton turning to greenish blue and grey respectively when converted into the copper complex compound). Specification 417,489 is referred to.
