Disclosed herein are para-phenylenediamine compounds of formula (I), and their salts and solvates:
wherein R
1
and R
2
form, together with the carbon atoms to which they are attached, a 4-, 5-, 6- or 7-membered ring, wherein the ring comprises carbon atoms and, optionally, one or two atoms chosen from oxygen and nitrogen, the ring being optionally substituted, with the proviso that when the ring comprises two atoms chosen from oxygen and nitrogen, these two atoms are non-adjacent. Compositions comprising these compounds and processes of making them, as well as processes and kits for dyeing keratin fibers are also disclosed.
本文披露了化学式(I)的对苯二胺化合物及其盐和溶剂合物:其中R1和R2与它们附着的碳原子一起形成4、5、6或7成员环,该环包括碳原子,可选择地包括一个或两个来自氧和氮的原子,该环可选择地被取代,但当环包括两个来自氧和氮的原子时,这两个原子不相邻。还披露了包含这些化合物的组合物、制备它们的方法,以及用于染色角蛋白纤维的方法和工具箱。
