as well as a method for temporarily coloring fibers, for which the coloration, obtained with the aforementioned coloring agent, can be removed once again at any time by a sulfite-colorizing agent.
Beschrieben wird eine photochrome Verbindung, die in an sich bekannter Weise ein Spirooxazin-Gerüst aufweist.
Erfindungsgemäß sind an das Grundgerüst konjungierte Diazol-naphtoxazin bzw. Oxazol-, Thiazol-, Benzooxazol-oder Benzthiazol-Systeme angelagert.
Hierdurch ergibt sich eine verbesserte Absorption im Wellenlängenbereich > als 350nm sowie verbesserte Migrationseigenschaften.
The present invention relates to an agent for dyeing keratin fibers, containing at least one compound with a nucleophilic reaction center, at least one alcohol from the group comprising aryl alcohol derivatives and benzyl alcohol derivatives and at least one suitable oxidizing enzyme, as well as to a method for dyeing keratin fibers using this agent.
