    • The present invention relates to a dye composition comprising at least four oxidation dye precursors, including at least one oxidation base chosen from suitably selected pyrazolopyridines and diamino-N,N-dihydropyrazolone derivatives and at least one coupler chosen from suitably selected cationic 3,5-diaminopyridines and 4-aminoindoles, 5-amino-6-chloro-2-methylphenol, 6-hydroxybenzomorpholine, 2-methyl-5-hydroxyethylaminophenol and 2-amino-3-hydroxypyridine, and also to the dyeing process using this composition. The present invention makes it possible in particular to obtain a composition for dyeing keratin fibers that is suitable for use in oxidation dyeing and that can produce colorations in varied shades, which are strong or chromatic, powerful, aesthetic, sparingly selective, and resistant to the various attacking factors to which the hair may be subjected, such as shampoo, sweat, permanent reshaping and light. The composition in accordance with the invention moreover shows good harmlessness and good stability.
    • 本发明涉及包含至少四种氧化染料前体的染料组合物,其包括至少一种选自适当选择的吡唑并吡啶和二氨基-N,N-二氢吡喃酮衍生物的氧化碱和选自适当选择的阳离子3,5-二 二氨基吡啶和4-氨基吲哚,5-氨基-6-氯-2-甲基苯酚,6-羟基苯并吗啉,2-甲基-5-羟乙基氨基苯酚和2-氨基-3-羟基吡啶,以及使用该组合物的染色方法。 本发明特别可以获得适用于氧化染色的角蛋白纤维染色用组合物,其可以产生各种色调的色泽,其颜色可以是强烈的或有色的,强大的,美观的,微小的选择性的,并且耐受 头发可能遭受的各种攻击因素,如洗发水,汗水,永久整形和光。 此外,根据本发明的组合物还显示出良好的无害性和良好的稳定性。
