are described as well as methods for preparing them. In addition, oxidation dye precursor compositions for dyeing keratin fibers, especially human hair, which each contain from 0.005 to 20 percent by weight of at least one of the new substituted 2,5-diamino-1-aminomethylbenzene compounds of formula (I), or their physiologically compatible water-soluble salts, are described. Methods for dyeing hair with ready-to-apply dye mixtures made by mixing these oxidation dye precursor compositions with an oxidizing agent, such as hydrogen peroxide solution, are also described.
描述了一种新的取代2,5-二氨基-1-氨甲基苯化合物(I)或其生理兼容性水溶性盐,以及制备它们的方法。此外,还描述了用于染色角蛋白纤维,特别是人类头发的氧化染料前体组合物,每种组合物含有按重量占0.005至20%的至少一种新的取代2,5-二氨基-1-氨甲基苯化合物(I)或其生理兼容性水溶性盐。还描述了使用这些氧化染料前体组合物与氧化剂(如过氧化氢溶液)混合制成的即用染料混合物来染发的方法。
