Abstract: The object of the invention are p-aminophenol derivatives of general formula (I) or physiologically tolerated, water-soluble salts thereof and oxidative coloring preparations based on a developer-coupler combination containing at least one p-aminophenol derivative of formula (I).

Abstract: The agent for dyeing keratin fibers contains one or more aryl and/or benzyl alcohols, one or more oxidizing enzymes, especially vanillyl oxidase, derivatives of vanillyl oxidase or galactose oxidase, and a nucleophilic compound that forms a dye for dyeing keratin fibers in the presence of the alcohols and enzymes. A method for dyeing keratin fibers with this agent is also disclosed. Two-component kits for performing the method of dyeing keratin fibers include a first compenent (A) and a second component (B) separate from the first component. The first component (A) includes the nucleophilic compound, the alcohol and optionally the oxidizing enzyme. The second component (B) includes the oxidizing enzyme when it is not included in the first component or more alcohol.
