Definitions

  • the present invention relates to agents for dyeing keratin fibers which contain special m-phenylenediamine derivatives, a process for dyeing hair using these agents, and some of these m-phenylenediamine derivatives themselves and intermediates which are formed in the preparation of these compounds.
  • oxidation coloring agents play a preferred role because of their intense colors and good fastness properties.
  • colorants contain oxidation dye precursors, so-called developer components and
  • the developer components form the actual dyes under the influence of oxidizing agents or of atmospheric oxygen with one another or under coupling with one or more coupler components.
  • M-Phenylenediamine derivatives, naphthols, resorcinol and resorcinol derivatives, pyrazolones and m-aminophenols are generally used as coupler components.
  • Suitable coupler substances are in particular 1-naphthol, 1, 5-, 2,7- and 1, 7-dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinol monomethyl ether, m-phenylenediamine, 1-phenyl -3-methyl-pyrazolone-5, 2,4-dichloro-3-aminophenol, 1,3-bis (2,4-diaminophenoxy) propane, 2-chlororesorcinol, 4-chlororesorcinol, 2-chloro-6-methyl -3-aminophenol, 2-methylresorcinol, 5-methylresorcinol and 2-methyl-4-chloro-5-aminophenol.
  • Good oxidation dye precursors should primarily fulfill the following prerequisites: they must develop the desired color shades with sufficient intensity and authenticity in the oxidative coupling. You must also have a good ability to draw on the fiber, especially in the case of human hair, there must be no noticeable differences between damaged and newly grown hair (leveling ability). They should be resistant to light, heat, sweat, friction and the influence of chemical reducing agents, e.g. Perm liquids. After all, if they are used as hair dye, they should not stain the scalp too much, and above all they should be harmless from a toxicological and dermatological point of view. Furthermore, the coloring achieved should be easily removed from the hair again by bleaching, if it does not correspond to the individual wishes of the individual and is to be reversed.
  • the present invention therefore firstly relates to agents for dyeing keratin fibers, in particular human hair, containing at least one m-phenylenediamine derivative of the formula (I) in a cosmetically acceptable carrier as a coupler component.
  • radicals R 1 , R 2 , R 3 and R 4 independently of one another represent a hydrogen atom, a Cr to C 4 alkyl group, a C 2 to C 6 monohydroxyalkyl group, a C 3 to C 6 polyhydroxyalkyl group, a C to C 4 alkoxy (Cr to C 4 ) alkyl group or a radical of the formula (II)
  • X represents a saturated alkylene group having 2 to 6 carbon atoms, such as a linear or branched alkylene chain, an alkylene ring or the like

  • Keratinic fibers are to be understood according to the invention to mean furs, wool, feathers and in particular human hair.
  • the oxidation colorants according to the invention are primarily suitable for dyeing keratin fibers, there is in principle nothing to prevent their use in other areas, particularly in color photography.
  • the known acid addition salts can be prepared from them in the usual way. All statements in this document and accordingly the claimed scope of protection therefore relate both to the compounds present in free form and to their water-soluble, physiologically tolerable salts. Examples of such salts are the hydrochlorides, the hydrobromides, the sulfates, the phosphates, the acetates, the propionates, the citrates and the lactates. The hydrochlorides and the sulfates are particularly preferred.
  • Examples of the C to C 4 alkyl groups mentioned as substituents in the compounds according to the invention are the groups methyl, ethyl, propyl, isopropyl and butyl. Ethyl and methyl are preferred alkyl groups. Preferred C to C 4 alkoxy groups are the methoxy and ethoxy groups.

However, these writings do not give any indication of the excellent coloring properties of the m-phenylenediamines now claimed. Furthermore, the dyeings with the m-phenylenediamine derivatives now present in combination with p-phenylenediamine and its derivatives are distinguished by an improved stability to shades on the hair compared to the compounds of the prior art. The otherwise frequently observed redshift of the nuances is therefore significantly lower in the m-phenylenediamine derivatives now present, or is even completely omitted.
