Abstract

Secondary disazo dyes capable of forming metallic complex compounds are made by coupling a diazo compound with 8-aminoquinoline or its nuclear substitution products, again diazotizing and coupling with a further azo component. In an example, the dyestuff sulphanilic acid --> 8-aminoquinoline --> N - 3<1> - carboxyphenyl - J acid (deep blue on cotton when after treated with copper compounds) is described; 2 - naphthylamine - 4 : 8-disulphonic acid is also specified as a diazo component. Specification 417,489 is referred to.
