-
, (2008/06/13)
A keratinous fiber dye composition comprising a developer and a coupler, wherein the coupler is a 2-substituted amino-5-alkylphenol derivative represented by the following formula (1): STR1 wherein the all symbols are defined in the disclosure, is disclosed. The keratinous fiber dye composition imparts a color tone of a high chroma and is excellent in coloring power and fastness.
