An oxidation dye composition for keratin fibers, in particular for human keratin fibers such as the hair, comprising, in a medium which is suitable for dyeing, at least one oxidation dye precursor and optionally one or more couplers, which is characterized in that it also contains an anionic amphiphilic polymer containing at least one hydrophilic unit of an unsaturated olefinic carboxylic acid, and at least one hydrophobic unit which is a (C10-C30)alkyl ester of unsaturated carboxylic acid, preferably exclusively of said (C10-C30)alkyl ester of unsaturated carboxylic acid. The oxidation dye compositions are used in dyeing processes and dyeing devices.
