Agent, useful for oxidative coloring of keratin fibers, preferably e.g. human hairs, comprises 6-amino-2-hydroxy-pyridine derivative, as coupler component, in a carrier, further developer component and direct dye

摘要

Agent for coloring keratin fibers, preferably human hairs, comprises at least a 6-amino-2-hydroxy-pyridine derivative (I), as a coupler component, in a carrier. Agent for coloring keratin fibers, preferably human hairs, comprises at least a 6-amino-2-hydroxy-pyridine derivative of formula (I), as a coupler component, in a carrier. R1 : saturated, 5-15-membered heterocycle exhibiting at least one N atom and optionally containing up to 3 further heteroatoms of O or -NR3-, where the heterocycle is bonded to the aromatic ring system over N; R3 : H, 1-6C-alkyl, 2-6C-alkenyl or 1-6C-hydroxyalkyl; and R2 : H, 1-6C-alkyl, 2-6C-alkenyl, 1-6C-hydroxyalkyl, 2-6C-polyhydroxyalkyl, 1-6C-alkoxy, NH 2, di-(1-6C-alkyl)amino, halo or OH. An independent claim is included for a process for coloring the keratin fibers comprising applying the agent and washing the hair after an influential time. [Image].
