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

A process for dyeing keratin fibers, comprising preparing a mixture by mixing 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:
• i) 2-methoxymethyl-para-phenylenediamine of formula (I), addition salts thereof, solvates thereof/or solvates of the salts thereof:
• and
• ii) 2-γ-hydroxypropyl-para-phenylenediamine of formula (II), addition salts thereof, solvates thereof or solvates of the salts thereof:
• and
• at least one (poly)oxyalkylenated amino silicone 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(C3H6O)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;
• x is an integer ranging from 1 to 10,000;
• 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 multi-compartment device for dyeing keratin fibers, comprising at least a first compartment and a second compartment, wherein the first compartment comprises a) a dyeing composition and the second compartment comprises b) an oxidizing composition, wherein:
