Claim:
1. An agent for oxidatively dyeing keratinic 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 pyrimidine derivative selected from the group consisting of 2,4,5,6-tetraaminopyrimidine, 4-hydroxy-2,5,6-triaminopyrimidine, 2-hydroxy-4,5,6-triaminopyrimidine, and one of the physiologically acceptable salts of each recited pyrimidine as developer, (C) at least one m-diaminobenzene derivative selected from the group consisting of 2-(2, 4-diaminophenoxy) ethanol, 1-methoxy-2-amino-4-(2′-hydroxyethylamino)benzene, 2,6-bis(2′-hydroxy-ethylamino)-1-methylbenzene, and one of the physiologically acceptable salts of each recited m-diaminobenzene as coupler, and (D) at least one m-dihydroxybenzene derivative selected from the group consisting of resorcinol, 2-methylresorcinol, and 4-chlororesorcinol as coupler, wherein a molar ratio (C)/(D), defined as the molar ratio of all couplers of group (C) included in the agent to all couplers of group (D) included in the agent has a value of at least 0.5 and has a maximum value of 1.5.
