Abstract: The invention relates to compounds of formula ##STR1## in which X denotes a halogen atom, and R and R' denote a hydrogen atom, an alkyl, polyhydroxyalkyl, hydroxyalkoxyalkyl or alkoxyalkyl radical or an aminoalkyl radical optionally substituted on the nitrogen atom provided that at least one of the groups R and R' is a polyhydroxyalkyl, alkoxyalkyl or hydroxyalkoxyalkyl radical, and to dye compositions for keratinic fibres in which they are employed, to the preparation process and to intermediates.

Abstract: A cosmetic composition for application to the hair contains either (a) at least one compound having the formula ##STR1## wherein R is hydrogen, alkyl or halogen; andR' is hydrogen, alkyl, hydroxyalkyl, carbamylalkyl, mesylaminoalkyl, aminoalkyl, acylaminoalkyl, monoalkylaminoalkyl, dialkylaminoalkyl, piperidinoalkyl, morpholinoalkyl, carbamoyl, acyl or carbalkoxy; or (b) at least one of said compounds having formula I above and at least one benzene or heterocyclic oxidation base. The invention also relates to new couplers of formula I as well as to new indo compounds which result from the coupling of said compounds with an oxidation base. These cosmetic compositions for application to the hair are useful in direct dyeing, oxidation dyeing or simultaneous oxidation and direct dyeing or said hair.

Abstract: The invention relates to hair-dyeing compositions based on para-phenylenediamine. These compositions contain, as the oxidation dyestuff, para-phenylenediamine and one or more para-phenylenediamines of the formula ##STR1## in which R denotes alkyl or hydroxyalkyl and R' denotes a hydroxyalkyl group, and also their cosmetically acceptable salts, in a molar ratio para-phenylenediamine/compound(s) of the formula (I), expressed in terms of free bases, 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 is detected in the oxidizing dyeing composition.These compositions make it possible to obtain natural background colorations, ranging from black to light chestnut, of very good quality.
