Abstract: The invention relates to the compounds of the formula: ##STR1## in which R.sub.1 and R.sub.2 denote, independently of one another, a hydrogen atom, a C.sub.1 -C.sub.4 alkyl radical or a C.sub.2 -C.sub.3 mono- or polyhydroxyalkyl radical,Z and Z' denote, independently of one another, a C.sub.1 -C.sub.4 alkyl or C.sub.2 -C.sub.4 hydroxyalkyl radical, with the proviso that, when R.sub.1 and R.sub.2 simultaneously denote a hydrogen atom, Z and Z' do not simultaneously denote a methyl radical, and to their addition salts with an acid, to a process for preparation thereof and also to their use, by way of couplers, in an aqueous vehicle, in combination with at least one oxidation dye percursor of the para type, for the dyeing of human hair.The invention also relates to the intermediate compounds of the formula: ##STR2## in which R' denotes a hydrogen atom, a C.sub.1 -C.sub.4 alkyl radical, a C.sub.2 or C.sub.3 mono- or polyhydroxyalkyl radical, or an acetyl or .beta.

Abstract: A 2-alkyl-4-methoxy-5-aminophenol or a salt thereof; a 2-alkyl-4-methoxy-5-nitrophenol or 2-alkyl-4-methoxy-5-nitrophenyl mesylate, each an intermediate in the preparation of the 2-alkyl-4-methoxy-5-aminophenol; and a dyeing composition for keratin fibers comprising a color-developing material and the 2-alkyl-4-methoxy-5-aminophenol or the salt thereof as a coupling agent are disclosed.Further, a 2-alkyl-4-methoxy-5-substituted aminophenol or a salt thereof; a 2-alkyl-4-methoxy-5-substituted aminophenol derivative, whcih is an intermediate in the preparation of the 2-alkyl-4-methoxy-5-substituted aminophenol; and a dyeing composition for keratin fibers comprising a color-developing material and the 2-alkyl-4-methoxy-5-substituted aminophenol or the salt thereof as a coupling agent are disclosed.

Abstract: A process for the preparation of predominantly non-cyclic polyalkylenepolyamines comprising contacting a difunctional aliphatic alcohol with ammonia or a primary or secondary aliphatic amine in the presence of a catalyst selected from the group consisting of Group VB metal oxides, niobium phosphates, tantalum phosphates, and mixtures thereof. For example, monoethanolamine is aminated by ethylenediamine to predominantly linear and branched polyethylenepolyamines in the presence of a catalyst containing niobium oxide supported on boehmite alumina.

Abstract: New chloro-meta-phenylenediamines, their use as couplers in the oxidation dyeing of keratinous fibres, dyeing compositions for hair containing these compounds and dyeing process using the said compositions.The invention relates to the compounds of formula: ##STR1## in which Z and Z' denote, independently of one another, an alkyl radical having from 1 to 4 carbon atoms or a hydroxyalkyl radical having from 2 to 4 carbon atoms, andR.sub.1 and R.sub.2 denote, independently of one another, a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms or a mono- or polyhydroxyalkyl radical having 2 or 3 carbon atoms, to their addition salts with an acid, and to their use by way of couplers for the oxidation dyeing of keratinous fibres, especially human hair.These compounds, when they are combined with paraphenylenediamines, surprisingly give beige to light brown hues or purple hues of greater of lesser redness, depending on the substitution of the 5-amino group of the chlorobenzene.
