Composition comprising a particular oxidation dye precursor, a particular amino silicone and a polyol

A process for dyeing keratin fibers comprising preparing a mixture by mixing at least a) a dyeing composition and b) an oxidizing composition and subsequently applying the mixture to the hair, wherein:

• a) the dyeing composition comprises:
• at least one oxidation base chosen from 2-β-hydroxyethyl-para-phenylenediamine of formula (I), addition salts thereof, solvates thereof or solvates of the salts thereof:
• at least (poly)oxyalkylenated amino silicone, and
• at least one polyol,
• wherein at least one (poly)oxyalkylenated amino silicone is chosen from (AB)n type multiblock (poly)oxyalkylenated amino silicones, A being a polysiloxane block and B being a (poly)oxyalkylene block, including at least one amine group, said silicones having repeating units of the following general formulae (X) and/or (Y):
• [-(SIMe2O)xSiMe2-R-N(R″)-R′-O(C2H4O)a(C3H5O)b-R′-N(H)-R-] (X)
• [-(SIMe2O)xSiMe2-R-N(R″)-R′-O(C2H4O)a(C3H6O)b-] (Y)
• wherein in (X) and (Y):
• a is an integer greater than or equal to 1;
• b is an integer ranging from 4 and 200, inclusive;
• x is an integer ranging from 1 to 10,000, inclusive;
• R″ is a hydrogen atom or a methyl;
• R, which may be identical or different, represents a linear or branched divalent C2-C12 hydrocarbon-based radical, optionally including one or more heteroatoms;
• and
• R′, which may be identical or different, represents a linear or branched divalent C2-C12 hydrocarbon-based radical, optionally including one or more heteroatoms, and
• b) the oxidizing composition comprises one or more chemical oxidizing agents.

A multicompartment device for dyeing kerating fibers comprising a first compartment comprising a) a dyeing composition and a second compartment comprising b) an oxidizing composition, wherein:
