It is shown that phenols which are covalently linked into wool keratin may be coupled with diazonium compounds to give covalently linked dyes. In addition to the many simple phenols which have been shown in Parts I and II [10, 11] to link covalently, the amides of hydroxy- naphthoic acid are linked in this manner and are shown to give good colorations which are fast to subsequent alkaline washing.
