摘要：
The invention relates to compositions for hair dyeing which contain, as the oxidative dye-stuff, in a cosmetically acceptable medium, para-phenylenediamine and ortho-aminophenol, or their cosmetically acceptable salts, in a ratio para-phenylenediamine/ortho-aminophenol which is such that, after the addition of an equal volume of hydrogen peroxide of 20 volumes strength and application to the hair for 30 minutes, no Bandrowsky's base can be detected in the oxidizing dyeing composition.The compositions according to the invention make it possible to impart background colorations to the hair without the formation of Bandrowsky's base.
