Substitutes for 1-naphthylamine. Part 3-disazo direct dyes with 3-amino-4-methoxyacetanilide and 1-naphthylamine components

A parallel series of dyes using 3-amino-4-methoxy acetanilide and 1-naphthylamine as intermediate components, and 6-(N-phenyl)-amino-1-naphthol-3-sulphonic acid as a coupling component, together with some well known disazo components, have been synthesised and compared in order to identify effective substitutes for 1-naphthylamine.
