Abstract:
A process for dyeing at least one keratin fiber, comprising applying to said at least one keratin fiber a composition comprising:(a) at least one cationic compound chosen from: (1) compounds having formula (I) and the cosmetically acceptable salts thereof: â€ƒin which: n is an integer ranging from 1 to 4; R1 is chosen from alkyl groups; hydroxyalkyl groups; polyhydroxyalkyl groups; alkylhydroxyalkyl groups; alkylsulfonyl groups; carboxyalkyl groups; aminoalkyl groups; (dihydroxy)alkylaminoalkyl groups; alkyl-NRâ€²Râ€³ groups, wherein Râ€² and Râ€³, which may be identical or different, are each chosen from linear alkyl groups comprising from 1 to 4 carbon atoms and branched alkyl groups comprising from 1 to 4 carbon atoms, and Râ€² and Râ€³ may also form, together with the nitrogen atom to which they attached, at least one ring chosen from 5-membered aliphatic rings, 6-membered aliphatic rings, 5-membered heterocyclic rings, and 6-membered heterocyclic rings; and aryl rings; A and the nitrogen atom, N, together form at least one hydrocarbon-based ring, optionally substituted, chosen from unsaturated rings comprising 5 atoms; unsaturated rings comprising 6 atoms; aromatic rings comprising 5 atoms; and aromatic rings comprising 6 atoms; wherein said at least one hydrocarbon-based ring may be interrupted by at least one atom chosen from nitrogen, oxygen and sulfur; it being possible for said at least one hydrocarbon-based ring to be fused with at least one ring chosen from unsubstituted aromatic rings and substituted aromatic rings; and A is chosen from carbon, optionally substituted; nitrogen, optionally substituted; oxygen; and sulfur; and (2) compounds having formula (II) and the cosmetically acceptable salts thereof: â€ƒwherein: R1, R2, R3, R4, and R5, which may be identical or different, are each chosen from alkyl groups; hydroxyalkyl groups; polyhydroxyalkyl groups; alkylhydroxyalkyl groups; alkylsulfonyl groups; carboxyalkyl groups; aminoalkyl groups; (dihydroxy)alkylaminoalkyl groups; alkyl-NRâ€²Râ€³ groups, wherein Râ€² and Râ€³, which may be identical or different, are each chosen from linear alkyl groups comprising from 1 to 4 carbon atoms and branched alkyl groups comprising from 1 to 4 carbon atoms, and Râ€² and Râ€³ may also form, together with the nitrogen atom to which they attached, at least one ring chosen from 5-membered aliphatic rings, 6-membered aliphatic rings, 5-membered heterocyclic rings, and 6-membered heterocyclic rings; and aryl rings; B is chosen from â€”CHâ€” groups and nitrogen; at least one of R1 and R2, R2 and R3, R3 and R4, R5 and R1, R5 and B, and R4 and B may also form, together with the atoms to which they are attached, at least one hydrocarbon-based ring, optionally substituted, chosen from 5-membered unsaturated rings; 6-membered unsaturated rings; 5-membered aryl rings; 6-membered aryl rings; 5-membered heterocycles; and 6-membered heterocycles; wherein said at least one hydrocarbon-based ring may be interrupted by at least one atom chosen from nitrogen and sulfur; and (b) at least one compound chosen from: (1) aldehydes having formula (III) and the cosmetically acceptable salts thereof: â€ƒin which: R6 is chosen from groups having formula (III A): â€ƒin which: R7 and R8, which may be identical or different, are each chosen from hydrogen; alkyl groups; monohydroxyalkyl groups; polyhydroxyalkyl groups;.alkylhydroxyalkyl groups; alkoxy groups; â€”CF3 groups; and â€”OCF3 groups; R7 and R8, which may be identical or different, may also form, together with the atoms to which they are attached, at least one ring, optionally substituted, chosen from aryl rings; 5-membered heterocyclic rings; and 6-membered heterocyclic rings; m is an integer ranging from 0 to 3; and R9 is chosen from hydrogen; alkyl groups; monohydroxyalkyl groups; polyhydroxyalkyl groups; alkylhydroxyalkyl groups; alkoxy groups; â€”CF3 groups; â€”OCF3 groups; aryl groups, optionally substituted; alkylaryl groups, optionally substituted; 5-membered heterocyclic groups, optionally substituted; and 6-membered heterocyclic groups, optionally substituted; (2) ketones chosen from ketones having formula (IV), ketones having formula (V), and the cosmetically acceptable salts thereof: â€ƒin which: R10 is chosen from groups having formula (III A): â€ƒin which: R7 and R8, which may be identical or different, are each chosen from hydrogen; alkyl groups; monohydroxyalkyl groups; polyhydroxyalkyl groups; alkylhydroxyalkyl groups; alkoxy groups; â€”CF3 groups; and â€”OCF3 groups; R7 and R8, which may be identical or different, may also form, together with the atoms to which they are attached, at least one ring, optionally substituted, chosen from aryl rings; 5-membered heterocyclic rings; and 6-membered heterocyclic rings; m is an integer ranging from 0 to 3; R9 is chosen from hydrogen; alkyl groups; monohydroxyalkyl groups; polyhydroxyalkyl groups; alkylhydroxyalkyl groups; alkoxy groups; â€”CF3 groups; â€”OCF3 groups; aryl groups, optionally substituted; alkylaryl groups, optionally substituted; 5-membered heterocyclic groups, optionally substituted; and 6-membered heterocyclic groups, optionally substituted;
