ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to new p-diaminobenzene derivative compounds and compositions for dyeing keratin fibers containing these new compounds.
2. Prior Art
Oxidation dye compounds have long attained substantial importance in the art of dyeing keratin fibers, especially hair dyeing. The dyeing caused by those compounds occurs by reaction of certain developer substances with certain coupler substances in the presence of a suitable oxidizing agent. For example, 2,5-diaminotoluene, 2,5-diaminophenylethyl alcohol, p-aminophenol and 1,4-diaminobenzene can be used as developer substances, while resorcinol, 4-chlororesorcinol, 1-naphthol, 3-aminophenol and derivatives of m-phenylendiamine can be mentioned as coupler substances.
There are numerous additional requirements for oxidation dye compounds that are used to dye human hair besides color in the desired intensity. Thus the dye compounds must be unobjectionable in regard to toxicological and dermatological properties and must provide the desired hair color with a good light fastness, fastness to a permanent wave treatment, acid fastness and fastness to rubbing. The color of the hair dyed with the dye compounds in each case must be stable for at least 4 to 6 weeks to light, rubbing and chemical agents. Furthermore an additional requirement is the production of a broad palette of different color shades using different developer and coupler substances.
It is not possible to fulfill all the above-mentioned requirements with the currently known dye compounds.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide improved developer compounds that fulfill the above-described requirements in a special manner.
It has now been surprisingly found that the new p-diaminobenzene derivative compounds according to formula (I) fulfill the many requirements for developer compounds to an especially great extent. Particularly bright or intense color shades are produced using these developer substances with predominantly known coupler substances, which are however extraordinarily light fast and fast to washing.
The subject matter of the present invention is thus p-diaminobenzene derivative compounds of the following formula (I), or their physiologically compatible water-soluble salts:
