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.
一种用于角蛋白纤维的染料组合物被披露,包括一种特定类型的三氟甲基苯胺衍生物作为显色剂,以及一种偶联物质。该组合物提供了高度饱和度和色彩的生动度,以及良好的色牢度。使用该染料组合物进行染色可以确保各种显色剂-偶联剂组合,可以提供多种颜色,具有高度的色彩饱和度和生动度。所产生的颜色具有出色的耐光性、耐洗性和耐磨性。在作为显色剂使用的三氟甲基苯胺衍生物中,以下式的p-苯二胺型三氟甲基苯胺衍生物是一种新颖的化合物。其中X代表一种特定类型的单或多羟基烷基基团、烷基基团或其他有机基团。
