The subject matter of the present invention relates to an agent for oxidatively dyeing keratinous fibers, including, in a cosmetic carrier, (A) 4,5-diamino-1-(2-hydroxyethyl)-1H-pyrazole and/or one of the physiologically acceptable salts thereof as developer, (B) at least one p-diaminobenzene derivative from the group comprising p-toluylenediamine, 2-(2,5-diaminophenyl)ethanol, and/or one of the physiologically acceptable salts thereof as developer; (C) at least one m-diaminobenzene derivative from the group comprising 2-(2,4-diamino-phenoxy)ethanol, 1-methoxy-2-amino-4-(2′-hydroxyethylamino)benzene, and/or one of the physiologically acceptable salts thereof as coupler, and (D) at least one m-dihydroxybenzene derivative from the group comprising resorcinol, 2-methylresorcinol, and/or 4-chlororesorcinol as coupler, wherein the molar ratio of all the developers of group (A) included in the agent to all the developers of group (B) included in the agent, i.e., the molar ratio (A)/(B), has a value of at least 1.2. |
