    摘要： Dye compositions comprising a coupler having to the formula ##STR1## in which formula R.sub.1 and R.sub.2 are identical or different and represent a hydrogen atom or an alkyl radical having 1 to 2 carbon atoms and n represents a number equal to 1 or 2 and a paraphenylenediamine.This coupler is particularly suitable for use in a dyeing composition comprising paraphenylenediamines responding to the formula ##STR2## or the corresponding acid salts; formula in which R.sub.1, R.sub.2 and R.sub.3 are identical or different and represent a hydrogen atom, an alkyl or alkoxy radical having 1 to 2 carbon atoms, R.sub.4 and R.sub.5 are identical or different and represent a hydrogen atom, a alkyl radical, hydroxyalkyl, alkoxyalkyl in which the alkoxy group comprises 1 to 2 carbon atoms, carbamylalkyl, mesylaminoalkyl, acetylaminoalkyl, ureidoaminoalkyl, carbethoxyaminoalkyl, the alkyl groups in R.sub.4 and R.sub.5 having 1 to 3 carbon atoms, with the reservation that R.sub.1 or R.sub.3 represents hydrogen when R.sub.4 and R.sub.5 do not represent a hydrogen atom.

    摘要： The invention provides dyeing compositions for keratin fibres, which contain at least one dyestuff corresponding to the formula: ##STR1## in which R.sub.1 and R.sub.2 independently of one another denote a hydrogen atom, an alkyl group, a monohydroxyalkyl or polyhydroxyalkyl group, an alkyl group substituted by an alkoxy group, or an aminoalkyl group of which the amino group can optionally be monosubstituted or disubstituted by an alkyl group, and the radical R.sub.2 can also denote a phenyl group or a phenyl group substituted by an alkyl, hydroxyl or amino group, and Z denotes a hydrogen atom or an alkyl group, or their cosmetically acceptable salts. Many of the dyestuffs are novel.

    摘要： The invention relates to a process for the preparation of nitroanilines, which consists in reacting an amine RNH.sub.2, or ammonia, with 3,4-methylenedioxynitriobenzene to give the products of the formula: ##STR1## in which R denotes hydrogen, alkyl, monohydroxyalkyl or polyhydroxyalkyl, alkoxyalkyl or aminoalkyl of the formula: ##STR2## in which R.sub.1 and R.sub.2, which are identical or different, denote hydrogen, alkyl or monohydroxyalkyl or polyhydroxyalkyl and n denotes an integer from 2 to 4, or of the formula: ##STR3## in which A denotes OCH.sub.2 or ##STR4## and R.sub.1 denotes --CH.sub.2 CH.sub.2 OH or ##STR5## or their salts. The invention also relates to the dyeing compositions for keratin fibres, and in particular for hair, which contain a dyestuff of the above formula (I) in which R denotes alkyl, polyhydroxyalkyl, alkoxyalkyl or aminoalkyl of the abovementioned formula, and to the dyestuffs of the formula (I) in which R denotes alkoxyalkyl or aminoalkyl of the above formula, and of the formula (IIB), which are novel.
