Abstract
The present disclosure relates to agents for the oxidative coloring of keratinic fibers, which are characterized in hat they contain derivatives of anisole as novel developer molecules.
Claims11
An agent for dyeing keratinic fibers, the agent comprising, in a cosmetic carrier, at least one compound of the formula (I) and/or a physiologically compatible salt of a compound of the formula (I),
- in which
- R1, R3 independently of one another stand for a hydroxyl group or amino group, wherein the amino group may be substituted by a group Q,
- R2 stands for a hydroxy group or an amino group, wherein the amino group may be substituted by a group Q,
- Q stands for an alkyl group or an aryl group,
- X stands for a C1-C6 alkyl group or a group of the general formula (II),
- [(CH2)m—Z—(CH2)n]t (II)
- Z stands for an oxygen atom or an amino group,
- m stands for a number from 1 to 3,
- n stands for a number from 0 to 3,
- I stands for a number from 1 to 3, and
- Y stands for a hydrogen atom, a hydroxy group, an alkoxy group or an amino group, wherein the amino group may be substituted with one or two Q groups and Y stands for a hydrogen atom when n=0.

- X stands for a C1-C6 alkyl group or a group of the general formula (II),
- [(CH2)m—Z—(CH2)n]I (II)
- Z stands for an oxygen atom or an amino group,
- m stands for a number from 1 to 3,
- n stands for a number from 0 to 3,
- I stands for a number from 1 to 3, and
- Y stands for a hydrogen atom, a hydroxy group, an alkoxy group or an amino group, wherein the amino group may be substituted with one or two Q groups and Y stands for a hydrogen atom when n=0.
