New substituted 2,6-diaminotoluenes of the general formula I ##STR1## wherein R is a hydrogen atom and R.sup.1 is a radical of the formula Ia --CH.sub.2 --CH(A)--B (Ia) or R and R.sup.1 are independent from each other and are represented by the formula Ia and if A in formula Ia represents a hydrogen atom, B is a hydroxyl group or HO--CH.sub.2 -- group; if A denotes a methyl group, B is a hydroxyl group; with the proviso that formula I is not N-(2-hydroxyethyl)-2,6-toluylenediamine; processes for their preparation and coloring compositions for keratin fibers which contain them. The dyeings produced with the coloring compositions are stable, bright and intense in color. They have improved properties with respect to attack by perspiration, acid rain, detergents, sunlight, UV radiation, seawater and the like.
新的通式I的2,6-二氨基甲苯替代物##STR1##其中R为氢原子,R.sup.1为通式Ia --CH.sub.2 --CH(A)--B(Ia)的基团,或者R和R.sup.1彼此独立且由通式Ia表示,如果在通式Ia中A代表氢原子,则B为羟基或HO--CH.sub.2 --基团;如果A代表甲基基团,则B为羟基;但通式I不是N-(2-羟乙基)-2,6-甲苯二胺;它们的制备方法和含有它们的角蛋白纤维着色组合物。使用这些着色组合物产生的染色稳定,色彩鲜艳且强烈。它们在抵抗汗水、酸雨、洗涤剂、阳光、紫外线辐射、海水等方面具有改进的性能。
