    Abstract: Producing tetraazapentamethine compounds (I) comprising reacting an azine compound with an oxidizing agent, is new. Producing tetraazapentamethine compounds of formula (I) comprises reacting an azine compound of formula (VI) or (VII) with an oxidizing agent; [Image] [Image] W1a cationic heteroaromatic group of formula (II) or (III); W2a heteroaromatic group of formula (IV) or (V); Z14Z7 or Z1; Z15Z8 or Z2; Z16Z13 or Z0; R25R5 or R1; Z17Z9 or Z3; Z18Z10 or Z4; Z19Z11 or Z5; Z20Z12 or Z6; R26R8 or R3; R27R7 or R4; R28, R29H, 1-6C alkyl or 1-6C alkoxy, but not both H; Z0CR2, N or NR21; Z1O, S or NR9; Z2N or CR10; Z3N or CR11; Z4N or CR12; Z5N or CR13; Z5N or CR13; Z6N or CR14; Z7O, S or NR15; Z8N or CR16; Z9N or CR17; Z10N or CR18; Z11N or CR19; Z12N or CR20; Z13CR6, N or NR22; R2, R6, R10, R16H; 1-4C alkyl substituted with 0-3 of OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, NH2, 1-2C (di)alkylamino, COOH or SO3H; phenyl substituted with 0-2 of OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, NH2, 1-2C (di)alkylamino; COOH; sulfonylamino; R1, R4, R5, R7, R9, R15, R21, R221-6C alkyl substituted with 0-3 of OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, NH2, 1-2C (di)alkylamino, COOH or SO3H; R0, R3, R8, R11-R14, R17-R20H; 1-6C linear or branched hydrocarbyl with 0-3 unsaturations, optionally substituted with 1-3 of OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, NH2, 1-2C (di)alkylamino, COOH, SO3H, sulfonylamino, 2-4C (poly)hydroxyalkylamino or halo and optionally interrupted by O, N, S or SO2; phenyl optionally substituted with 1-3 of OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, NH2, 1-2C (di)alkylamino, COOH, SO3H, sulfonylamino, 2-4C (poly)hydroxyalkylamino or halo; pyrazolyl, pyrrolyl, imidazolyl, thiazolyl, oxazolyl, triazolyl, pyridyl, pyrimidinyl, triazinyl, pyrazinyl or pyridazinyl; X : an anion; R2+R10, R11+R12, R6+R16, R17+R18 can form a 5-6C aromatic ring substituted with 0-2 of OH, NH2, 1-2C (di)alkylamino, 1-2C alkoxy, 2-4C (poly)hydroxyalkylamino. An independent claim is also included for dyeing keratinic fibers by applying (VI) or (VII) onto the wet or dry fibers in the presence of an oxidizing agent. [Image].

    Abstract: Oxidation dye composition for dyeing keratinic fibers comprises an alcohol oxidase enzyme (I) and a substrate for (I), where (I) is a primary alcohol oxidase (EC 1.1.3.13), a secondary alcohol oxidase (EC 1.1.3.18), a long-chain hydrocarbon alcohol oxidase (EC 1.1.3.20), a polyvinyl alcohol oxidase (EC 1.1.3.30), a vanillyl alcohol oxidase (EC 1.1.3.38) or an aromatic alcohol oxidase (EC 1.1.3.7). Independent claims are also included for: (1) a method for dyeing keratinic fibers, comprising applying the above composition to the fibres for a time sufficient for the desired color to develop; (2) a kit comprising an oxidation dye composition in one compartment and a composition containing an enzyme as above in another compartment, where one or both compositions contain a substrate for the enzyme.
