Definitions

  • the invention relates to agents for dyeing keratin fibers containing special Diaminobenzolderivate developer component in combination with at least one coupler component, a process for dyeing keratin fibers with these agents, and the use of the dye combinations according to the invention in cosmetic centers, in particular for dyeing keratin fibers.
  • keratin fibers are understood to mean furs, wool, feathers and, in particular, human hair.
  • Human hair is today treated in a variety of ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures and the bleaching, dyeing and shaping of the hair with dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role.
  • dyeing or tinting agents which contain so-called direct drawers as a coloring component. These are dye molecules that grow directly on the hair and do not require an oxidative process to form the color. These dyes include, for example, the henna already known from antiquity for coloring body and hair. These dyes are against Shampooing is usually sensitive, so that a much undesirable nuance shift or even a visible "discoloration" can occur.
  • oxidation dyes play a special role because of their intense colors 1 and good fastness properties, which are achieved at relatively low dyeing temperature and in short dyeing times.
  • colorants contain in a suitable, usually aqueous carrier, a developer component which forms the dye under the influence of atmospheric oxygen or oxidizing agents by oxidative coupling.
  • This dye can be intensified by coupling with another developer component or with so-called coupler components, which themselves can not form dyes, and modified in nuance.
  • Good oxidation dye precursors are primarily intended to meet the following requirements: They must form the desired color shades in sufficient intensity and authenticity in the oxidative coupling. You must also have a good AufziehFab on the fiber, especially in human hair no significant differences between strained and freshly regrowed hair may exist (leveling ability). They should be resistant to light, heat, friction and the influence of chemical reducing agents, e.g. Perm liquids. Finally, if applied as a hair dye, they should not stain the scalp too much and above all they should be safe in terms of toxicology and dermatology. Furthermore, the coloring achieved by bleaching should be easily removed from the hair, if it does not meet the individual wishes of each person and should be reversed.
