Abstract: The present invention relates to a dyeing composition comprising 2-y-hydroxypropyl-p-phenylenediamine and at least one phosphoric surfactant. The phosphoric surfactant is of formula (I) in which: R1, R2 and R3, which may be identical or different, represent a group chosen from: —a group —OM, in which M represents a hydrogen atom or an alkali metal; —a group —OR4, in which R4 represents a linear or branched C12-C40 alkyl group, a linear or branched C2-C40 alkenyl group, a C3-C40 cyclic alkyl group, a C3-C40 cyclic alkenyl group, a C5-C40 aromatic group or a C6-C40 aralkyl group; and —an oxyalkylene group —(OCH2CH2)n(OCH2CH(CH3))mOR4 in which R4 is defined as above, n represents an integer ranging from 1 to 50 and m represents an integer ranging from 0 to 50; and given that at least one of the groups R1, R2 and R3 is a group —OM and that at least one of the groups R1, R2 and R3 is a group —OR4 or —(OCH2CH2)n(OCH2CH(CH3))mOR4. The present invention also relates to a process for dyeing keratin fibres, comprising the application of the composition according to the invention to the fibres. The invention also relates to the use of the combination 2-y-hydroxypropyl-para-phenylenediamine/phosphoric surfactant, for dyeing keratin fibres.
