    摘要: ##STR1## By dehydrating indolines or their salts, the corresponding indoles having formula (I) are obtained. In the formula, R
    1 and R
    3 represent independently from each other hydrogen or alkyl groups with 1 to 4 C atoms, R
    2 stands for hydrogen, a methyl or a carboxyl group, R
    4 and R
    5 represent independently from each other hydrogen, amino groups, hydroxy groups, alkyl groups with 1 to 4 C atoms or alkoxy groups with 1 to 4 C atoms, or, in case R
    4 and R
    5 are bound to adjacent C atoms, both residues may also represent together an alkylene dioxy group with 1 to 4 C atoms. This process allows high yields of very pure indoles to be produced.

    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.
