The invention relates to a process for dyeing keratin fibres, comprising the use of one or more metal catalysts and o f a composition (A) comprising : - one or more oxidizing agents, and - at least one monoaminobenzene of formula (I), or an addition salt or solvate thereof in which the radicals R1 to R5 represent, independently of each other: a hydrogen atom; a halogen atom, a C1-C6 alkyl radical, a C1-C6 alkoxy radical, a carboxylic radical (-COOH), a sulfonic radical (-S03 H); two of the adjacent radicals R1 to R5 possibly forming, with the carbon atoms that bear them, a saturated or unsaturated 5- to 7-membered ring, optionally comprising from 1 to 2 heteroatoms, preferably oxygen, the said ring being optionally fused with a saturated or unsaturated 5- to 6- membered ring; on condition that at least one of the radicals R1 to R5 represents an optionally substituted alkoxy radical and preferably at least one of the other radicals R1 to R5 is a hydrogen atom.
