Abstract: Hair dyeing compositions contain N-cycloalkyl-3-aminophenols corresponding to the following formula ##STR1## in which n is an integer of 4 to 8 and R.sup.1, R.sup.2, and R.sup.3 independently of one another represent hydrogen, methyl groups or chlorine,or salts thereof as oxidation dye intermediates of the coupler type in addition to typical primary intermediates in a carrier. In conjunction with typical primary intermediates, for example of the p-phenylenediamine derivative type, the new coupler compounds produce shades of brown of high fastness.

Abstract: Compounds of formula I are disclosed: ##STR1## and their salts with inorganic and organic acids, wherein either X denotes H and Y denote OR or HNR, or X denotes OR or NHR and Y denotes H, and R represents hydroxy(C.sub.2 -C.sub.3) alkyl, 2,3-dihydroxypropyl, methoxy(c.sub.2 -C.sub.3) alkyl, tetrahydrofurylmethyl or tetrahydropyrylmethyl. Processes are described for the preparation of compounds of formula I as well as aqueous coloring agents for keratin fibers, such as fur and human hair, containing at least one compound of formula I as the coupler and at least one developing component, as well as customary additives and auxiliaries.
Abstract: Composition for the oxidative dyeing of hair based on a combination of developer substances and coupler substances contains, as developer substance, a diaminopyrazol of the general formula (I), ##STR1## wherein R.sup.1, R.sup.2 and R.sup.4 are identical or different and designate hydrogen, alkyl with 1 to 4 carbon atoms, hydroxyalkyl with 2 to 4 carbon atoms, benzyl or phenyl, and R.sup.3 is hydrogen, alkyl with 1 to 4 carbon atoms, hydroxyalkyl with 2 to 4 carbon atoms, with the proviso that the amino groups are in 3,4 or 4,5 position, or its physiologically tolerated, water-soluble salt, new diaminopyrazol derivatives of the above general formula I are also described herein in which R.sup.1 is methyl or benzyl and the R.sup.2 and R.sup.4 are either benzyl, phenyl, hydrogen, alkyl with 1 to 4 carbon atoms or hydroxyalkyl with 2 to 4 carbon atoms and R.sup.3 is either hydrogen, alkyl with 1 to 4 carbon atoms or hydroxylakyl with 2 to 4 carbon atoms.

Abstract: Process for dyeing human keratinous fibres, characterized in that there are applied on these fibres, in separate stages, a composition (A) containing a metal salt chosen from copper, iron, cobalt, magnesium, and silver salts, or mixtures thereof, in a cosmetically acceptable medium, and, before or after the application of the composition (A), a composition (B) containing, in a cosmetically acceptable medium, at least one dye corresponding to the formulae: ##STR1## in which formulae R.sub.1 denotes hydrogen or hydroxy, R.sub.2 and r.sub.3 denote hydrogen, alkyl, alkoxy; R.sub.4 denotes hydrogen, hydroxy, alkoxy, alkyl, chlorine; R.sub.5 denotes hydrogen, chlorine, alkoxy, hydroxy; and R.sub.6, R.sub.7 and R.sub.8 denote hydrogen or hydroxy.
Abstract: Iron complex dyes which are particularly suitable for dyeing leather in brown shades are obtained by coupling a naphthylaminesulfonic acid with resorcinol, subsequently coupling the reaction product with 4-nitro-2-aminophenol and metallizing with an iron compound.
Abstract: Process for dyeing hair in several separate steps consisting in applying a cosmetically acceptable composition containing at least one cupric salt and, before or after this application, a cosmetically acceptable composition containing a dye chosen from brazilin and its hydroxyl derivative.
Abstract: The invention relates to a dyeing composition for keratinous fibres containing, in a suitable vehicle, at least one nitrated direct dye of the 2-nitro-paraphenylenediamine series, in which the amino group in position 4 is mono- or disubstituted with lower alkyl or hydroxyalkyl radicals and in which the amino group in position 1 is optionally monosubstituted with a lower alkyl or hydroxyalkyl radial, and the aromatic ring can be substituted or unsubstituted on the remaining positions; the invention consists in introducing into such a composition an imidazolidinedione or one of its substitution derivatives, to improve the solubility of the abovementioned nitrated direct dye by a co-solubilization phenomenon. The invention also relates to a process for dyeing keratinous fibres using such compositions.
