Patent ID: 8202326

Claim:
A hair dye composition comprising an alkaline chemical and an oxidation dye intermediate composed of a major intermediate and a coupler, wherein at least one member selected from (1) organic compounds having not more than 4 carbon atoms, which has both of a —SH group and a —NH 2 group and does not have a —COOH group and (2) salts thereof is contained as a component (A), and at least one member selected from aromatic compounds which are specific meta couplers in which the same or different substituents arbitrarily selected from the groups represented by the following chemical formula 1 and chemical formula 2 are each attached to meta positions of a mononuclear benzene ring structure and α-naphthol is contained as a component (B) which is the coupler, and the blending amount of each member of the component (B) is in a range from 0.01 to 0.5% by mass: wherein R1 and R2 are each arbitrarily selected from hydrogen, hydrocarbon groups having not more than 2 carbon atoms, and aliphatic alcohol groups having not more than 2 carbon atoms or salts thereof and R1 and R2 are the same or different groups from each other; and —OR [Chemical formula 2] wherein R is arbitrarily selected from hydrogen, hydrocarbon groups having not more than 2 carbon atoms, and alcohol groups having not more than 2 carbon atoms or salts thereof.
