ABSTRACT:
A dye composition for keratinous fibers comprising a specific type of trifluoromethylated aniline derivative, as a developer, and a coupling substance is disclosed. The composition provides high degree of saturation and vividness of colors as well as good fastness. Dyeing with the use of the dye composition ensures a variety of developer-coupling agent combinations, which can provide a wide variety of colors with a high degree of color saturation and vividness. The color produced possesses excellent light resistance, washing resistance, and wear resistance. Amoung the trifluoromethylated aniline derivative, used as a developer, a p-phenylenediamine-type trifluoromethylated aniline derivative of the following formula is a novel compound. ##STR1## in which X represents a specific type of mono- or polyhydroxyalkyl group, alkyl group, or other organic group.
