Abstract:
1. 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 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 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.
