    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.

    摘要: Dyeing compositions are disclosed which comprise at least one oxidation dyestuff precursor in combination with at least one direct dyestuff, in an aqueous vehicle, the direct dyestuff being a nitro derivative of the benzene series having the formula: ##STR1## in which R.sub.1 denotes the methyl group, R.sub.2 and R.sub.4 denote hydrogen and R.sub.3 denotes the .beta.-hydroxyethoxy group, or alternatively R.sub.1, R.sub.3 and R.sub.4 denote hydrogen and R.sub.2 denotes the methyl or hydroxyl group, or alternatively R.sub.1 and R.sub.2 denote hydrogen, R.sub.3 denotes the methyl group and R.sub.4 denotes the hydroxyl, (.beta.-hydroxyethyl)-amino or (.beta.-N,N-diethylaminoethyl)-amino group, or R.sub.1, R.sub.2 and R.sub.3 denote hydrogen and R.sub.4 denotes the N,N-bis-(.beta.-hydroxyethyl)-amino group.
