Abstract: The invention relates to a process for dyeing keratin fibres, preferably the hair, comprising the application to said keratin fibres of a composition comprising at least one oxidation dye base chosen from para-phenylenediamine derivatives of formula (I), their addition salts, their solvates and/or the solvates of their salts, in which R is chosen from a (C1-C4)alkoxy(C1-C4)alkyl radical and a C1-C4 hydroxyalkyl radical, at least one compound chosen from N,N-dicarboxymethylglutamic acid, one of its salts and mixtures thereof and a chemical oxidizing agent. The process may comprise the step of mixing a dyeing composition comprising the oxidation dye base and the N,N-dicarboxymethylglutamic acid compound with an oxidizing composition comprising one or more chemical oxidizing agents and applying the obtained mixture to the keratin fibres. A multi-compartment device comprises a first compartment containing the dyeing composition and a second compartment containing the oxidizing composition.
