  The invention concerns a composition for dyeing keratin fibres, in particular human keratin fibres such as hair comprising at least one pyrazolin-4,5-dione of formula (I) and at least one aromatic primary amine. Said composition enables R the dyeing of keratin fibres without an oxidising agent in shades which are strong, varied, resistant and less selective than those of prior art. The invention also concerns dyeing methods and devices using said composition.

  本发明涉及一种用于染色角蛋白纤维，特别是人类角蛋白纤维（如头发）的组合 物，该组合物包含至少一种式（I）的吡唑啉-4,5-二酮和至少一种芳香族伯胺。与现有技术相比，该组合物无需氧化剂即可对角蛋白纤维进行染色，染色色调浓烈、多变、耐受性强且选择性较低。本发明还涉及使用所述组合物的染色方法和设备。
