| titleOfInvention | 2,5-Diaminopyridine oxidation bases, dye preparations for staining keratin fibers containing them, and method for staining keratin fibers |
| abstract | The present invention relates to a dye composition comprising as suitable dye oxidation base at least one 2,5-diaminopyridine derivative of formula (I) or a corresponding addition salt thereof, wherein Z1 is OR3 or NR4R5, R1, R2, R4 and R5 are independently hydrogen, C 1-6 alkyl, C 2-6 (poly) aminoalkyl, C 2-6 (poly) alkylaminoalkyl, C 2-6 aminohydroxyalkyl, C 2-6 acylaminoalkyl, C 2-6 alkoxyalkyl, 2 C 6 -C 6 hydroxyalkoxyalkyl, C 2 -C 6 aminoalkoxyalkyl, C 2 -C 6 (poly) hydroxyalkyl, C 2 -C 6 carboxyalkyl or C 2 -C 6 sulfoalkyl; R1 and R2, and R4 and R5, independently of the nitrogen atom to which they are attached, may also form a saturated 5-8 membered heterocyclic group which may be optionally substituted with one or more of the following groups: halogen, amino, (di) alkylamino, hydroxyl, carboxyl, carboxamido or alkoxy, or C 1-6 alkyl optionally substituted one or more times by hydroxyl, amino, (di) alkylamino, alkoxy, hydroxy, alkoxy, aminoalkoxy, carboxyl or sulfo, and the heterocyclic group may contain one or more additional heteroatoms selected from oxygen, nitrogen (optionally substituted) or sulfur or SO2, and the heterocyclic group contains neither a peroxide bond nor a diazosemitroso group; R3 is a straight-chain or branched alkyl having 1 to 6 carbon atoms which may be substituted one or more times by a hydroxyl, amino, C1-C3 mono- or dialkylamino group, the alkyl moiety of which is optionally one or more hydroxyl, amino, May be substituted by C 1-2 alkoxyalkoxy or carboxyl; with the exception of 2,3,6-triaminopyridine or its acid addition salts. Also within the scope of the invention are the novel compounds of formula (I) and the dyeing process with the compositions of the invention. SHE |
