| titleOfInvention | Quaternized azafluorenones and their use in agents for dying fibers containing keratin |
| abstract | The invention relates to quaternized azafluorenones of formula (I) in which: R<1>, R<2>, R<3> and R<4> represent a hydrogen atom, a halogen atom, a C1-C4 alkyl group, a C1-C4 alkoxy group or a C1-C4 hydroxyalkoxy group, a hydroxy group, a nitro group, an amino group, which can be substituted by C1-C4 alkyl groups, or a C1-C4 acyl group, whereby two of the radicals, together, can also form a fused aromatic ring; Q1, Q2, Q3 and Q4, in total, represent three carbon atoms and a quaternary nitrogen atom which carries the radical R<5> that signifies a C1-C4 alkyl group, a C1-C4 hydroxyalkyl group, a C1-C4 carboxyalkyl group, a C1-C4 sulfoalkyl group, an aryl group, an aralkyl group or a heteroaryl group or also an N oxide; and Y<-> represents halogenide, C1-C4 alkyl sulfate, arene sulfate, C1-C4 alkane sulfonate, C1-C4 perfluoralkane sulfonate, perhalogenate, sulfate, hydrogen sulfate, tetrafluoroborate, hexafluorophosphate, tetrachlorozincate or oxide of an N oxide. These compounds are suited for dying fibers containing keratin, especially human hairs. |
