Abstract: Composition (A) for coloring keratin fibers, preferably hair, comprises: one or more fatty substance free of amide function; and one or more cationic direct dyes having tetraazapentamethine structure (I), in a medium. Composition (A) for coloring of keratin fibers, preferably human keratin fibers, especially hair, comprises: one or more fatty substance free of amide function; and one or more cationic direct dyes having tetraazapentamethine structure of formula (W 1-N=N-C(R 0)=N-N=W 2) (I), in a medium. W 1heteroaromatic cationic group of formula (II) or (III); W 2heteroaromatic group of formula (IV) or (V); Z 0N, CR 2or NR 21; Z 1O, S, NR 9or CR 13; Z 2CR 10; Z 3CR 11; Z 4CR 12; Z 5N, CR 3, or C; Z 6N or CR 14; Z 7O, S, NR 15or CR 19; Z 8N or CR 16; Z 9N or CR 17; Z 10N or CR 18; Z 11N, CR 8or C; Z 12N or CR 20; Z 13CR 6, N or NR 22; T : OH, 1-2C alkoxy, 2-4C (poly)-hydroxyalkoxy, NH 2, (di)(1-2C alkyl)amino, carboxy or sulfonic group; R 1, R 4, R 5, R 7, R 9, R 15, R 21, R 221-8C alkyl (optionally substituted by 1-3 groups of T); either R 2, R 6, R 10, R 13, R 16, R 19H, 1-4C alkyl (optionally substituted by 1-3 groups of T), phenyl (optionally substituted by 1-3 groups of OH, 1-2C alkoxy, 2-4C (poly)-hydroxyalkoxy, NH 2or (di)(1-2C alkyl)amino), carboxy, or sulfoamino (HO 3S-NH-); and R 0, R 3, R 8, R 11, R 12, R 14, R 17, R 18, R 20H, 1-16C hydrocarbon chain (optionally saturated and substituted by 1-3 groups of T, sulfoamino, 2-4C (poly)hydroxyalkylamino or halo (preferably Cl, F or Br)), hydrocarbon chain (optionally interrupted by one or two O, N, S or SO 2), 1-4C alkoxy (optionally substituted by 1 or 2 OH groups), phenyl (optionally substituted by OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, (di)(1-2C alkyl)amino, carboxy, sulfonic group or halo (preferably Cl, F or Br)), 5-6 membered aromatic heterocyclic groups (preferably pyrazolyl, pyrrolyl, imidazolyl, thiazolyl, oxazolyl, triazolyl, pyridinyl, pyrimidinyl, triazinyl, pyrazinyl or pyridazinyl or their cationic equivalents of N, or N having 1-6C alkyl), sulfoamino (HO 3S-NH-), carboxy, amino, (di)(1-4C alkyl)amino or 2-4C (poly)-hydroxyalkylamino; or R 2R 10, R 11R 12, R 6R 16, R 17R 185-6 membered aromatic cycle optionally substituted by one or two groups of OH, NH 2, (di)(1-2C alkyl)amino, 1-2C alkoxy, or 2-4C amino(poly)hydroxyalkyl; and X ->organic or inorganic anion. Where: the groups (II)-(V) does not have more than three nitrogen atoms, and two of the three nitrogen atoms can be adjacent; the bond a of 5 membered cationic heteroaromatic group (II) is linked to N, which is linked to W 1of (I); the bond b of 6 membered cationic heteroaromatic group (III) is linked to N, which is linked to W 2of (I); the double bond c of 5 membered heteroaromatic group (IV) is linked to the N, which is linked to W 2of (I); the double bond d of 6 membered heteroaromatic group (V) is linked to the N, which is linked to W 2of (I); the bond b, linking the heteroaromatic group (III) to N, which is linked to W 1of (I), is situated in ortho position of the N carrying the group R 4when Z 5is -CR 3-, or in para position of the N carrying the group R 4, when Z 5is C, or in ortho position of the N carrying the group R 4, when Z 5is N; or the bond c, linking the heteroaromatic group (V) to N, which is linked to W 2of (I), is situated in ortho position of the N carrying the group R 7, when Z 11is -CR 8-, or in para position of the N carrying the group R 7, when Z 11is C, or in ortho position of the N carrying the group R 7, when Z 11is N; and R 0, R 3, R 8, R 11, R 12, R 14, R 17, R 18and R 20are not having peroxide bond, diazo or nitroso group. Independent claims are included for: (1) a method of coloring keratin fibers, particularly human keratin fibers, comprising: either applying (A) to the fiber for a sufficient time to develop the desired coloration, rinsing and optionally shampooing, rinsing again and drying; or applying (A) to the fiber for a sufficient time to develop the desired coloration without final rinsing; or storing a composition (A1) comprising (I) in a medium, in separated form, and composition (B1) comprising one or more oxidizing agent, and then mixing at the time of use before applying the mixture on the keratin fibers, where (A1) and (B1) comprise one or more fatty substance; or storing a composition in separated form (A2) comprising (I) and oxidation base in a medium, and composition (B2) comprising one or more oxidizing agent, and then mixing at the time of use before applying the mixture on the keratin fibers, where (A2) and (B2) comprise one or more fatty substance; and (2) a device with several-compartment or kit with several compartments, comprising a first compartment containing composition (A1) or (A2); and a second compartment containing the composition (B1) or (B2).
