Dye compositions comprising, in a medium suitable for dyeing: at least one first oxidation base chosen from 4,5-diaminopyrazole derivatives of formula (I) and addition salts thereof, at least one second cationic oxidation base chosen from monobenzenic, dibenzenic and heterocyclic oxidation bases, and the addition salts thereof, comprising at least one cationic group Z chosen from aliphatic chains optionally bearing at least one ring chosen from saturated and unsaturated rings; wherein said at least one cationic group Z is linked directly to at least one benzenic ring or to at least one heterocycle of said at least one second cationic oxidation base or linked to at least one amine functional group borne by said at least one benzenic ring or said at least one heterocycle; and at least one coupler; as well as the use of this composition for dyeing keratin fibres and the dying process using this composition.
