Abstract (en)
[origin: WO2006119818A1] The invention relates to agents for dyeing keratin-based fibres, in particular human hair, comprising in a cosmetic vehicle, compounds of formula (I) and/or a enol form thereof, wherein not more than two rests R1, R2, R3 and R4 are independently of each other a hydrogen atom, a halogen atom, a hydroxy group, a cyano group, a nitro group, a carboxyl group, a sulphonamide group, a (C<SUB>1</SUB>C<SUB>6</SUB>)-alkyl group, a (C<SUB>1</SUB>C<SUB>6</SUB>)-alkoxy group, a (C<SUB>2</SUB>-C<SUB>6</SUB>)-alkenyl group, an optionally substituted aryl group, an optionally substituted heterocycle, an aryl-(C<SUB>1</SUB>C<SUB>6</SUB>)-alkyl group, a (C<SUB>2</SUB>-C<SUB>6</SUB>)-hydroxyalkyloxy group, a C<SUB>2</SUB>-C<SUB>6</SUB>)-hydroxyalkyl group, a (C<SUB>2</SUB>-C<SUB>6</SUB>)-polyhydroxyalkyl or a R<SUP>I</SUP>R<SUP>II</SUP>N-(CH<SUB>2</SUB>)<SUB>m</SUB> group, wherein R<SUP>I</SUP> and R<SUP>II</SUP> are independently of each other a (C<SUB>1</SUB>C<SUB>6</SUB>)-alkyl group, a (C<SUB>2</SUB>-C<SUB>6</SUB>)-alkenyl group or a aryl-(C<SUB>1</SUB>C<SUB>6</SUB>)-alkyl group, wherein R1 and R11 can form jointly with a hydrogen atom a cyclic 5, 6 or 7-membered compound, m is an 0, 1, 2, 3, 4, 5 or 6 number and X is an oxygen atom, a sulphur atom, or an NR5 group, wherein R5 is a hydrogen atom a (C<SUB>1</SUB>C<SUB>6</SUB>)-alkyl group, a (C<SUB>2</SUB>-C<SUB>6</SUB>)-alkenyl group, an aryl-(C<SUB>1</SUB>C<SUB>6</SUB>)-alkyl group, a (C<SUB>2</SUB>-C<SUB>6</SUB>)-hydroxyalkyloxy group, an alkoxy (C<SUB>1</SUB>C<SUB>6</SUB>)-alkyl group or a (C<SUB>2</SUB>-C<SUB>6</SUB>)-polyhydroxyalkyl group, provided that at least two rests adjacent between R1, R2, R3 and R4 form jointly with a residual molecule an optionally substituted condensed an aromatic, carbocyclic or heterocyclic ring, or an optionally substituted condensed aromatic, carbocyclic or heterocyclic ring combination. The inventive dyeing agents are used for revitalising or nuancing already dyed keratin-based fibres.
