A hair dye composition comprising the following components (A), (B) and (C) and having pH (25° C.) of 7.5 or more and 12 or less: (A): one or more azo dyes selected from the group consisting of the following (A-1), (A-2) and (A-3): (B): a cationic compound (C): 0.1 mass % or more and 8 mass % or less of at least one alkali metal salt of an acid selected from the group consisting of hydrochloric acid, carbonic acid and sulfuric acid.

First claim

Opening claim text (preview).

1 - 16 : (canceled) 17 : A hair dye composition comprising the following components (A), (B) and (C) and having pH (25° C.) of 7.5 or more and 12 or less: (A): one or more azo dyes selected from the group consisting of the following (A-1), (A-2) and (A-3): (B): a cationic compound represented by the following formula (1): wherein R 1 , R 2 , R 3 and R 4 each independently represent a hydrogen atom or a hydrocarbon group; one or two of R 1 , R 2 , R 3 and R 4 have 8 to 36 carbon atoms and the remainders represent a hydrogen atom or a hydrocarbon group having 1 to 7 carbon atoms; and X-represents an anion; (C): 0.1 mass % or more and 8 mass % or less of at least one alkali metal salt of an acid selected from the group consisting of hydrochloric acid, carbonic acid and sulfuric acid; wherein a molar ratio of the component (B) relative to a total of the component (A) and the component (C) in the whole composition, (B)/[(A)+(C)], is 0.01 or more to 8 or less. 18 : The hair dye composition according to claim 17 , wherein the molar ratio of a whole component (B) relative to the total of a component (A) and a component (C) in a whole composition, (B)/[(A)+(C)], is 0.02 or more and 2.01 or less. 19 : The hair dye composition according to claim 17 , wherein the component (B) is one or more member selected from the group consisting of lauryl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, and behenyl trimethyl ammonium chloride. 20 : The hair dye composition according to claim 17 , wherein a content of the component (B) is 0.05 mass % or more and 20 mass % or less of the whole composition. 21 : The hair dye composition according to claim 17 , further comprising an anionic surfactant (D1) or a nonionic surfactant (D2) as a component (D). 22 : The hair dye composition according to claim 21 , wherein the component (D) is one or more member selected from the group consisting of an alkyl sulfate salt, a polyoxyalkylene alkyl sulfate salt, a fatty acid salt, an alkyl ether carboxylate salt, an alkyl glyceryl ether, and an alkyl polyglucoside. 23 : The hair dye composition according to claim 21 , wherein a content of the component (D) is 0.1 mass % or more and 20 mass % or less of the whole composition. 24 : The hair dye composition according to claim 21 , wherein a mass ratio of the component (B) relative to a total of the component (A) and the component (D1) in the whole composition, (B)/[(A)+(D1)], is 1.2 or less. 25 : The hair dye composition according to claim 17 , further comprising an alkali agent as a component (E) in an amount of 0.01 mass % or more and 20 mass % or less of the whole composition. 26 : A method for dyeing hair, comprising: applying the hair dye composition according to claim 17 to the hair, allowing to stand for 1 to 60 minutes, and washing away the composition.
