Keith C. Brown , John F. Corbett

ABSTRACT

Synopsis

A study of the REACTIONS OF P -AMINOPHENOLS with m -diamines, m -aminophenols, and resorcinol, under OXIDATIVE conditions, is described. Oxidation of p -aminophenol to p -benzoquinone monoimine is followed by coupling to the meta compound and oxidation to give N-( p -hydroxyphenyl) aminobenzoquinone diimines, aminoindophenols and hydroxyindophenols, respectively. Visible spectra of the dyes are related to DYE COLOR ON HAIR and stability in solution is related to color stability on hair.
