Abstract:
A hair dye composition, comprising:a one-part aqueous formulation containing a direct dye compound represented by formula (1), (II), (III) or (IV): wherein, m stands for 0, 1 or 2, n stands for 1 or 2,m units of R1 and n units of R4 each independently represents a hydrogen atom, a C1-4 alkyl group or a halogen atom, m units of R2 each independently represents a hydrogen atom, a C1-4 alkyl group or an aryl group, with the proviso that at m=2, two R2s, taken together with the adjacent &boxH;Câ€”CH&boxH;Câ€”, may form a carbocyclic structure or an oxygen-containing heterocyclic structure, n units of R3 each independently represents a hydrogen atom or a C1-4 alkyl group, n units of R5 each independently represents a hydrogen atom or a C1-4 alkyl group, or is bonded, via a group â€”COâ€”Oâ€”, to a ring B5 to form a lactone ring, R6 represents a hydrogen atom or a C1-4 alkyl group, A1 represents the below-described formula (1), (2) or (3), A2 represents the below-described formula (4), A3 represents the below-described formula (5), (6), (7), (8) or (9), A4 and Z1 each independently represents the below-described formula (10), (11), (12), (13), (14), (15) or (16), Z2 represents the below-described formula (17), Z3 represents the below-described formula (18), (19), (20) or (21): â€ƒwherein a broken line means the presence or absence of bonding, D1 represents an oxygen atom, a sulfur atom or a group NR25, D2 represents an oxygen atom, a sulfur atom, a group NR26 or a group CR27R28, D3 represents a nitrogen atom or a group CR29, D4 represents an oxygen atom, a sulfur atom or a group NR30, R7, R8, R9, R14 and R25 each independently represents a C1-6 alkyl group which may have a substituent, R10, R11, R13, R15, R16, R21, R22, R27, R28 and R29 each independently represents a hydrogen atom or a C1-6 alkyl group, R12 and R26 each independently represents a hydrogen atom or a C1-6 alkyl group which may have a substituent, R17 and R18 each independently represents a hydrogen atom, a C1-6 alkyl group which may have a substituent or an aryl group which may have a substituent, or R17 and R18, taken together with the adjacent nitrogen atom, form a nitrogen-containing heterocycle or one or both of R17 and R18 is (are) bonded to the ring B5 to form a nitrogen-containing heterocycle, R19 and R23 each independently represents an aryl group which may have a substituent, R20 represents a C1-6 alkyl group, R24 and R30 each independently represents a hydrogen atom, a C1-6 alkyl group which may have a substituent, or an aryl group which may have a substituent, Y1 and Y2 each independently represents an oxygen atom or a sulfur atom, rings B1, B2, B3 and B4 each independently has a ring structure which may have, as a substituent, a halogen atom, an aryl group or a C1-4 alkyl group or may further be cyclocondensed with a benzene ring, B5 has a ring structure which may have, as a substituent, a halogen atom, an aryl group or a C1-4 alkyl group, may be condensed with a benzene ring, or may be bonded to R17 or R18 to have a ring structure which may be cyclocondensed with a nitrogen-containing heterocycle, and Xâˆ’ represents an anion, with the proviso that Xâˆ’ does not exist when R7, R8, R9 and R25 each has a sulfonium group as a substituent, the composition having a pH ranging from 6-11 that is adjusted to within said range by an alkali agent and containing at least one cosmetic ingredient selected from the group consisting of hydrocarbons, animal or vegetable fats and oils, fatty acids, organic solvents, hair penetration promoters, cationic surfactants, natural or synthetic polymers, alcohols, ethers, amphoteric surfactants, nonionic surfactants, protein derivatives, amino acids, antiseptics, chelating agents, stabilizing agents, antioxidants, plant extracts, crude drug extracts, vitamins, colorants, perfumes, aerosolizing agents and UV absorbers.
