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).

The invention claimed is: 1. 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 diallyl quaternized ammonium salt polymer derivative (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 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 from 0.08 to 2.00. 2. The hair dye composition according to claim 1 , 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 0.08 to 1.5. 3. The hair dye composition according to claim 1 , wherein the component (B) is one or more member selected from the group consisting of dimethyl diallyl ammonium chloride polymer, a dimethyl diallyl ammonium chloride/acrylic acid copolymer, a dimethyl diallyl ammonium chloride/acrylamide copolymer, a dimethyl diallyl ammonium chloride/acrylic acid/acrylamide polymer, and hydroxyethylcellulose/dimethyl diallyl ammonium chloride copolymer. 4. The hair dye composition according to claim 1 , wherein a nitrogen content in the component (B) is 0.3 mass % or more and 9.0 mass % or less. 5. The hair dye composition according to claim 1 , wherein a content of the component (B) is 0.01 mass % or more and 10 mass % or less of a whole composition. 6. The hair dye composition according to claim 1 , wherein a content of component (C) is 0.2 mass % or more and 7 mass % or less of the whole composition. 7. The hair dye composition according to claim 1 , further comprising an anionic surfactant (D1) or a nonionic surfactant (D2) as a component (D). 8. The hair dye composition according to claim 7 , 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. 9. The hair dye composition according to claim 7 , wherein a content of the component (D) is 0.1 mass % or more and 20 mass % or less of the whole composition. 10. The hair dye composition according to claim 1 , 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. 11. 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 diallyl quaternized ammonium salt polymer derivative (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 and sulfuric acid. 12. The hair dye composition according to claim 11 , wherein the component (C) is one or more member selected from the group consisting of sodium chloride, potassium chloride, sodium sulfate, and potassium sulfate. 13. A method for dyeing hair, comprising: applying the hair dye composition according to claim 1 to the hair, allowing to stand for 1 to 60 minutes, and washing away the composition.
