Abstract

An agent for oxidatively dyeing of keratinic fibers includes, 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 2,4,5,6-tetraaminopyrimidin, 4-hydroxy-2,5,6-triaminopyrimidin, 2-hydroxy-4,5,6-triaminopyrimidin and/or one of the physiologically acceptable salts thereof as developer, (C) at least one m-diaminobenzene derivative selected from 2-(2,4-diaminophenoxy)ethanol, 1-methoxy-2-amino-4-(2′-hydroxyethylamino)benzene, 2,6-bis(2′-hydroxy-ethylamino)-1-methylbenzene, and/or one of the physiologically acceptable salts thereof as coupler, and (D) at least one m-dihydroxybenzoyl derivative selected from resorcinol, 2-methylresorcinol and/or 4-chlororesorcinol as coupler.
