    摘要: 1,3-disubstitued nitrobenzenes of the general formula I: ##STR1## in which X is a hydroxyl group or an amino group and R.sup.1 is hydrogen or a C.sub.1-4 alkyl group and their salts are suitable for use as an oxidation dye precursor of the coupler type, together with prior art primary intermediate components, for the production of oxidation dyes, preferably for the production of hair colorants. With developers of the p-phenylenediamine, p-aminophenol, 2.5-diaminopyridine, and 2,4,5,6-tetraaminopyrimidine types, primarily brown hues with great light stability are formed.

    摘要: 2,4-Dichloro-3-alkylidene-aminophenols having the formula: ##STR1## wherein R.sub.1 represents hydrogen or an alkyl radical having 1 to 6 carbon atoms and R.sub.2 represents an alkyl radical having 1 to 6 carbon atoms or an aryl radical, with the proviso that R.sub.2 can only be an aryl radical when R.sub.1 is hydrogen.The 2,4-dichloro-alkylidene-aminophenols can be produced by reaction of 2,4-dichloro-3-aminophenol with the corresponding aldehydes or ketones. They are suitable as such, or in the form of their salts with inorganic or organic acids, as coupler components in oxidation hair dyes.

    摘要: Oxidizable developer-coupler combinations wherein the coupler is a water-soluble polyhalogen 3-aminophenol are stable in the absence of free oxygen and chemical oxidizing agents. They provide hair dyeings of specially desirable shades. The dyeings are color fast, wash-fast, thermostable, and non-toxic. The combinations can be applied in customary vehicles. Their dyeing properties are developed by air oxidation, by peroxides, or by both at an acid, neutral or alkaline pH.
