    Abstract: A hair dyeing composition comprising a special developer and a coupling agent is disclosed. The developer is a 4-aminophenol derivative substituted at the 2-position which is represented by the following formula (I), in which X represents a group -NHCOR (R is a linear or branched alkyl group having 1-5 carbon atoms), a group -COOR [R is a hydrogen atom, a linear or branched alkyl group having 1-5 carbon atoms, a monohydroxy alkyl group having 1-5 carbon atoms, a polyhydroxy alkyl group having 1-5 carbon atoms, or a group -(CH2)nNR R (R and R individually represent a hydrogen atom or a linear or branched alkyl group having 1-5 carbon atoms, and n denotes an integer of 1-5)], a group -CONHR , a nitrile group, a group -SO3R , or a group -SO2NR2_2 (R has the same meaning as defined above and the two R s may be the same or different), or a salt thereof. The dye composition provides a high degree of saturation and vividness of colors as well as good fastness.

    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. in which X represents a specific type of mono- or polyhydroxyalkyl group, alkyl group, or other organic group.
