1,3-Diamino-4-(aminomethyl)-benzene derivatives of the general Formula (I) or their physiologically tolerated, water-soluble salts, as well as agents for the oxidative dyeing of fibers, containing these compounds.
摘要:
Dyeing agents for keratin fibers, containing N-heteroarylmethyl-m-phenylenediamine derivatives of general formula (I) or the salts thereof and new N-heteroarylmethyl-m-phenylenediamine derivatives.
摘要:
New substituted 2,5-diamino-1-aminomethylbenzene compounds of formula (I), or physiologically compatible water-soluble salts thereof, are described as well as methods for preparing them. In addition, oxidation dye precursor compositions for dyeing keratin fibers, especially human hair, which each contain from 0.005 to 20 percent by weight of at least one of the new substituted 2,5-diamino-1-aminomethylbenzene compounds of formula (I), or their physiologically compatible water-soluble salts, are described. Methods for dyeing hair with ready-to-apply dye mixtures made by mixing these oxidation dye precursor compositions with an oxidizing agent, such as hydrogen peroxide solution, are also described.
