Abstract: The present invention relates to a composition for dyeing keratin fibers, in particular keratin fibers such as the hair, comprising: a) at least one oxidation base 3-(2,5-diaminophenyl)-1-propanol and/or acid salts thereof and/or solvates thereof such as hydrates; b) at least one coupler; c) at least one polymer chosen from cationic polymers and amphoteric polymers, and mixtures thereof; d) at least one fatty substance; the total amount of fatty substances being at least 10%, e) optionally at least one basifying agent; and f) optionally at least one chemical oxidizing agent. The invention also relates to a process for dyeing keratin fibers such as the hair using the composition of the invention, and to a multi-compartment device for using the composition of the invention.
