  The subject of the invention is a composition for dyeing keratin fibres, comprising at least one 1,8-dihydroxynaphthalene derivative and at least one basifying agent other than aqueous ammonia; the use of the composition for hair dyeing and also the use of the composition in a dyeing process for keratin fibres. The composition according to the invention makes it possible to dye keratin fibres under mild oxidizing conditions even without using an oxidation base and an aromatic amine, while at the same time covering a broad colour range with 1,8-dihydroxynaphthalene derivatives. The observed dyeing under oxidizing conditions operates under mild conditions of oxidation and/or basifying agent, in particular in the air, and does not produce any unpleasant odour.
