Patent number: 6878169Abstract: 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.Type: GrantFiled: December 16, 2002Date of Patent: April 12, 2005Assignee: Kao CorporationInventor: Kenichi Matsunaga
