L'INVENTION EST RELATIVE A DES COMPOSITIONS TINCTORIALES POUR FIBRES KERATINIQUES CARACTERISEES PAR LE FAIT QU'ELLES CONTIENNENT AU MOINS UN COLORANT REPONDANT A LA FORMULE:(CF DESSIN DANS BOPI)DANS LAQUELLE R ET R DESIGNENT INDEPENDAMMENT L'UN DE L'AUTRE UN ATOME D'HYDROGENE, UN GROUPEMENT ALKYLE, UN GROUPEMENT ALKYLE MONO- OU POLYHYDROXYLE, UN GROUPEMENT ALKYLE SUBSTITUE PAR UN GROUPEMENT ALCOXY, UN GROUPEMENT AMINOALKYLE DONT LE GROUPEMENT AMINO PEUT EVENTUELLEMENT ETRE MONO- OU DISUBSTITUE PAR UN GROUPEMENT ALKYLE, LE RADICAL R PEUT EGALEMENT DESIGNER UN GROUPEMENT PHENYLE, OU PHENYLE SUBSTITUE PAR UN GROUPEMENT ALKYLE, HYDROXYLE, OU AMINO, Z DESIGNE UN ATOME D'HYDROGENE OU UN GROUPEMENT ALKYLE OU LEURS SELS COSMETIQUEMENT ACCEPTABLES. The invention provides dyeing compositions for keratin fibres, which contain at least one dyestuff corresponding to the formula: in which R1 and R2 independently of one another denote a hydrogen atom, an alkyl group, a monohydroxyalkyl or polyhydroxyalkyl group, an alkyl group substituted by an alkoxy group, or an aminoalkyl group of which the amino group can optionally be monosubstituted or disubstituted by an alkyl group, and the radical R2 can also denote a phenyl group or a phenyl group substituted by an alkyl, hydroxyl or amino group, and Z denotes a hydrogen atom or an alkyl group, or their cosmetically acceptable salts. Many of the dyestuffs are novel.
