Composition for dyeing of keratinic fibers comprising a cationic derivative of p-phenylenediamine substituted by a diazacyclohexane or a diazacyloheptane

摘要

Specified derivatives of paraphenylenediamine and their addition salts and of para-nitroaniline, their use in hair dyeing compositions and the compositions themselves. The derivatives of paraphenylenediamine are of formula (I) R 1H, 1-8C hydrocarbon chain in which one or more carbon atoms may be replaced by one or more of O or N or Si or S or SO 2; n : 1-4; R 2, R' 2alkyl non- substituted or substituted with one or more carboxyl or alkylcarbonyl or alkoxycarbonyl or carbamoyl or mono- or dialkylcarbamoyl or heterocyclics with 4-7 atoms where the heteroatoms are N or O or S, CH 2R; R : alkyl substituted with one or more hydroxy or alkoxy or hydrogenothio or halogeno or amino or mono- or dialkylamino or amine substituted by alkylcarbonyl or carbamyl or alkylsulfonyl, aryl, benzyl; R 3H, alkyl, hydroxy, hydroxyalkyl, alkoxy, alkoxyalkyl, alkylcarbonyl, hydroxyalkoxyalkyl, amino optionally mono or disubstituted with alkyl or acetyl or hydroxyalkyl, mono- or dialkylamino, aminoalkyl optionally mono- or disubstituted on the amine with alkyl, acetyl or hydroxyalkyl, hydroxy and amino alkyl, carboxyl, carboxyalkyl, carbamoyl, carbamoalkyl, alkoxycarbonyl, mono- or dialkylaminocarbonyl, mono- or dialkylaminocarbonylalkyl; R 4alkyl, hydroxyalkyl, alkoxyalkyl, alkylcarbonyl, hydroxyalkoxyalkyl, aminoalkyl optionally mono- or disubstituted on the amine with alkyl or acetyl or hydroxyalkyl, hydroxy- and aminoalkyl, carboxyl, carboxyalkyl, carbamoyl, carbamoylalkyl, alkoxycarbonyl, mono- or dialkylaminocarbonyl, mono- or dialkylaminocarbonylalkyl; m : 0-4; X ->a counter ion; R 1 does not comprise a peroxide bond nor diazo, nitro or nitroso radicals. The para-nitroaniline derivatives are of formula (II); The paraphenylenediamine derivative substituted with a diazacyclohexane group and of Formula (I) n, m : 0; R 2, R' 2methyl. and 4-(4-nitrophenyl)-1,1- dimethylpiperazin-1-ium are both specifically excluded from the claim. Independent claims are included for: (1) a method of dyeing keratinic fibers by applying the composition in the presence of an oxidant for a sufficient time to develop the desired color; (2) a device comprising several compartments, one of which contains the claimed composition and another the oxidant.
