    • Provided is a hair dye composition containing a direct dye (1): [wherein, R1, R2, R3, R4, R5 and R6 each represents a C1-6 alkyl group; R7 and R8 each represents a hydroxy group, a C1-6 alkyl group, a C1-6 alkoxy group, an amino group or alkylamino groups; R9 represents a hydrogen atom or a C1-6 alkyl group; and X− represents an anion]. This hair dye composition undergoes a small change in color tone even after storage because it contains the direct dye (1) which has high stability against any one of an alkali agent, oxidizing agent and reducing agent, and at the same time, has markedly high hair dyeing power and exhibits excellent light resistance, washing resistance, perspiration resistance, friction resistance and heat resistance.
    • 本发明提供含有直接染料(1)的染发剂组合物:[其中R 1,R 2,R 3,R 4,R 5和R 6各自表示C1 -6烷基; R 7和R 8各自表示羟基,C 1-6烷基,C 1-6烷氧基,氨基或烷基氨基; R 9表示氢原子或C 1-6烷基; 并且X'表示阴离子]。即使在保存后,这种染发剂组合物也经历色调的小变化,因为它含有对碱金属,氧化剂和还原剂中的任一种具有高稳定性的直接染料(1) 同时具有显着高的染发力,并且具有优异的耐光性,耐洗涤性,耐汗性,耐摩擦性和耐热性。

    • Provided is a hair dye composition containing a direct dye (1), (2) or (3). This hair dye composition has markedly high hair dyeing power, has less color fade over time and undergoes a small change in the color tone of the dye even after storage. wherein, R1 represents a (substituted) aryl group, R2, R4 to R6, R8 and R9 each represents H, a (substituted) C1-6 alkyl group or a (substituted) aryl group, R3 and R7 each represents a (substituted) aryl group, R10 to R12 each represents a (substituted) C1-6 alkyl or (substituted) aryl group, rings A to G each represents a benzene ring which may be substituted by a (substituted) amino group, (substituted) C1-6 alkyl group, C1-6 alkoxy group or halogen atom or may further be cyclocondensed with a benzene ring, and X− represents an anion.
    • 提供含有直接染料(1),(2)或(3)的染发剂组合物。 这种染发剂组合物具有显着高的染发力,随着时间的推移,颜料褪色量减少,即使在保存后也会使染料的色调发生小的变化。其中R1表示(取代的)芳基,R2,R4〜R6, R 8和R 9各自表示H,(取代的)C 1-6烷基或(取代的)芳基,R 3和R 7各自表示(取代的)芳基,R 10〜R 12各自表示(取代的)C 1-6烷基或 (取代)芳基,环A至G各自表示可被(取代的)氨基,(取代的)C 1-6烷基,C 1-6烷氧基或卤素原子取代的苯环,或者可以进一步与 苯环,X-表示阴离子。
