1. Hair dyeing composition on the basis of an oxidation dyestuff precursor reacting with peroxide, which contains developing and coupling substance(s) comprising
a) 3-chloro-p-aminophenol;
b) at least one compound selected from the group consisting of: 2-methyl-5-γ-hydroxypropyl aminophenol, 2-methyl-5-methyl aminophenol, 2-methyl-5-ethyl aminophenol, 2-methoxy-5-aminophenal, 2-methyl-4-methoxy-5-aminophenol and 2-methyl-4-methoxy-5-hydroxyethyl aminophenol; and
c) at least one compound selected from the group consisting of 1-methoxy-2,4-diaminobenzene, 1-β-hydroxyethyloxy-2,4-diaminobenzene, 1-(1,2-dihydroxypropyloxy)-2,4-diaminobenzene, 1-methoxy-2-amino-4-β-hy-droxyethyl aminobenzene, 1,3-bis-(2,4-diaminophenoxy)-propane, 2,4-diamino-5-methyl-phenol and/or 1-β-hydroxyethyloxy-5-methyl-2,4-diaminobenzene
wherein said developing and/or coupling substance(s) includes salt forms thereof and said hair dyeing composition produces hair colorations in the range of red.
2. The hair dyeing composition of claim 1 wherein the total concentration of the developing substance is from 0.05% to 5% by weight, calculated from the total weight of the hair dyeing composition excluding the oxidation agent.
3. The hair dyeing composition of claim 1 which further comprises of a shading agent in an amount of from about 0.05% to about 2.5% by weight based on the total weight of the hair dyeing composition (excluding the oxidizing agent).
4. The hair dyeing composition of claim 3 wherein the shading agent is a nitro dyestuff.
