Zusammenfassung:	Dyes with brilliant copper and gold shades can be obtained by using oxidation colorants, containing 2-aminophenol as a coupling constituent and a compound of formula (I) as a developing agent, wherein X stands for a hydroxyl group or a group NR R , R and R independently stand for hydrogen, a hydroxyalkyl or alkyl group with 1 to 4 carbon atoms each, or stand for a heterocyclic ring system in combination with the nitrogen atom carrying them, and Y, Z and T independently stand for a hydroxyl group or an amino group with the proviso that a maximum of two of the substituents X, Y, Z and T are hydroxyl groups.
