Definitions
- the present invention relates to novel cationic heteroarylazine dyes and colorants for keratin fibers, such as hair, wool or furs, containing these compounds.
- oxidation dyes which result from the oxidative coupling of one or more developer components with one or more coupler components
- direct dyes are generally used.
- oxidation-stable, direct dyes can be added to the oxidative system in order to achieve special color effects.
- Direct dyes are incorporated into suitable substrates to be applied to the fiber. This process, commonly known as tinting, is easy to use, extremely mild and is characterized by little damage to the keratin fiber, since no ammonia or peroxide is added.
- the dyes used here have to meet some requirements. For example, they have to be harmless from a toxicological and dermatological point of view and enable the coloring to be achieved in the desired intensity and brilliance.
- the dyeings obtained must also have good light fastness and resistance to shampooing and good rub fastness.
- a combination of different non-oxidative dyes is generally required for a direct, non-oxidative colorant for keratin fibers in order to achieve certain nuances. Since the selection of such dyes, which sufficiently meet the requirements mentioned, is limited, there is still a great need for such dyes.
- the object of the present invention is therefore to provide direct dyes for dyeing keratin fibers, in particular hair, which meet these requirements.
- cationic heteroarylazine dyes of the general formulas (I) and (II) can be applied very gently to keratin fibers as direct dyes in coloring compositions without the addition of an oxidizing agent.
