Abstract[German]
Gegenstand der vorliegenden Erfindung ist ein Mittel (F) zum Färben von keratinischen Fasern, insbesondere menschlichen Haaren, enthaltend (F-1) mindestens ein Pigment, und (F-2) mindestens ein Chitosan und/oder ein Chitosanderivat, dadurch gekennzeichnet, dass das Gewichtsverhältnis aus allen im Mittel enthaltenen Pigmenten (F-1) zu allen im Mittel enthaltenen Chitosan(derivat)en (F-2), d.h. das Gewichtsverhältnis (F-1)/(F-2), im Bereich von 1,00:1,05 bis 1,00:2,45 liegt.[English]
The invention relates to an agent (F) for dyeing keratin fibers, in particular human hair, containing (F-1) at least one pigment and (F-2) at least one chitosan and/or chitosan derivative, characterized in that the weight ratio of all pigments (F-1) contained in the agent to all chitosan (derivatives) (F-2) contained in the agent, i.e. the weight ratio (F-1)/(F-2), is in the range of 1.00:1.05 to 1.00:2.45.[French]
L'invention se rapporte à un agent (F) de coloration des fibres kératiniques, en particulier des cheveux humains, contenant (F-1) au moins un pigment et (F-2) au moins du chitosane et/ou un dérivé de chitosane, caractérisé en ce que le rapport pondéral de tous les pigments (F-1) contenus dans l'agent sur tous les chitosanes (dérivés) (F-2) contenus dans l'agent, c'est-à-dire le rapport pondéral (F-1)/(F-2), est compris entre 1,00:1,05 et 1,00:2,45.
