Patent ID: 8231690

Claim:
A composition for the coloring of keratin fibres in a medium suitable for the coloring of keratin fibres and comprising at least one dye represented by formula (1) in which X is selected from a hydrogen atom; an alkyl radical having from 1 to 10 carbon atoms and optionally substituted with one or more hydroxyl radicals; a phenyl radical optionally substituted with one or more C 1 -C 10 hydroxyl or alkyl radicals, a hydroxyl radical, R1 is selected from a hydrogen atom; a hydroxyl radical; a benzoyl or p- hydroxybenzoyl radical; a phenyl radical optionally substituted with one or more C 1 -C 10 hydroxyl or alkyl radicals, an amino radical NH 2 or NHR or NRR′, R and R′ representing a C 1 -C 10 alkyl or hydroxyalkyl radical, and R and R′ can form, with the nitrogen atom to which they are attached, an aromatic or non-aromatic ring, R2 is selected from a hydroxyl radical; an amino radical NH 2 or NHR or NRR′, R and R′ being as defined previously; a phenyl radical optionally substituted with one or more C 1 -C 10 hydroxyl or alkyl radicals, R3 is selected from a hydrogen atom; a hydroxyl radical; an alkyl radical having from 1 to 10 carbon atoms and optionally substituted with one or more hydroxyl radicals; a radical COR′″ or COOR′″ with R′″ representing a hydrogen atom, a C 1 -C 10 alkyl radical, an amino radical NH 2 or NHR or NRR′, R and R′ being as defined previously, R4 is selected from a hydrogen atom, a C 2 -C 10 alkenyl radical optionally substituted with one or more hydroxyl radicals; a hydroxyl radical; a radical COOR′″ or COR′″ with R′″ equal to hydrogen, a C 1 -C 10 alkyl radical; an amino radical NH 2 or NHR or NRR′, R and R′ being as defined previously, R2 and R4 or R1 and R3 taken two at a time can together form an aromatic or non-aromatic, heterocyclic or carbocyclic ring with 5 or 6 ring members, R5 and R6 represent independently a hydrogen atom; a hydroxyl radical; an amino radical NH 2 and NHR or NRR′, R and R′ being as defined previously, and one or more surfactants or one or more thickening agents or both.
