    摘要： There are described dyeing compositions for keratin fibres, and in particular for human hair, containing a dyestuff of the formula: ##STR1## in which A denotes an alkylene group, an alkylene group substituted by one or more OH groups, or an alkylene group interrupted by a hetero-atom such as oxygen or by an --NH-- group, R.sub.1 and R.sub.2, which are identical or different, denote hydrogen, alkyl, monohydroxyalkyl or polyhydroxyalkyl, or R.sub.1 and R.sub.2 can together form a heterocyclic ring chosen from among piperidino or morpholino groups, Y denotes alkoxy or NO.sub.2, R denotes hydrogen or lower alkyl, and if Y denotes alkoxy, Z denotes NO.sub.2 and is located in the para-position to the amine group, and if Y denotes NO.sub.2, (a) Z denotes alkoxy or OH and is located in the para-position to the NO.sub.2 group, or alternatively (b) Z denotes OH and is located in the para-position to the amine group, and also their cosmetically acceptable salts. Many of these dyestuff are novel.

    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.
