Claim:
A cosmetic composition for treating keratin fibers, comprising: at least one organosilicon compound chosen from silanes comprising one, two and three silicon atoms, wherein the at least one organosilicon compound also comprises at least one basic chemical function and at least one group chosen from hydroxyl and hydrolysable groups per molecule; at least one hydrophobic film-forming polymer; at least one pigment; and at least one volatile solvent; wherein the at least one organosilicon compound comprising one silicon atom is chosen from the compounds of formula (I): wherein: R 4 represents a halogen, a group OR′, or R′ 1 ; R 5 represents a halogen, a group OR″, or R′ 2 ; R 6 represents a halogen, a group OR′″, or R′ 3 ; R 1 , R 2 , R 3 , R′, R″, R′″, R′ 1 , R′ 2 , and R′ 3 represent, independently of each other, a saturated or unsaturated, linear or branched hydrocarbon-based group optionally bearing additional chemical groups, wherein R 1 , R 2 , R′, R″, and R′″ also can be hydrogen, and at least two of the groups R 4 , R 5 , and R 6 are different from the groups R′ 1 , R′ 2 , and R′ 3 . and wherein the at least one organosilicon compound comprising two or three silicon atoms is chosen from the compounds of formula (II): (R 21 O) x (R 22 ) y Si—(B) p —[NR 23 —(B′) p′ ] q —[NR′ 23 —(B″) p″ ] q′ —Si—(R′ 22 ) y′ (OR′ 21 ) x′ (II) wherein: R 21 , R 22 , R′ 21 , and R′ 22 each independently represent a saturated or unsaturated, linear or branched hydrocarbon-based chain, optionally comprising at least one heteroatom, optionally interrupted or substituted with at least one group chosen from ether, ester, amine, amide, carboxyl, hydroxyl, and carbonyl groups, x is an integer ranging from 1 to 3, y=3−x, x′ is an integer ranging from 1 to 3, y′=3−x′, p=0 or 1, p′=0 or 1, p″=0 or 1, q=0 or 1, q′=0 or 1, on the condition that at least q or q′ is other than zero, B, B′, and B″ each independently represent a linear or branched divalent C 1 -C 20 alkylene radical, R 23 and R′ 23 each independently represent a hydrogen atom or a saturated or unsaturated, linear or branched hydrocarbon-based chain, optionally comprising at least one heteroatom, optionally interrupted or substituted with at least one ether, ester of a C 1 -C 20 alcohol, amine, carboxyl, alkoxysilane, C 6 -C 30 aryl, hydroxyl or carbonyl groups, or a heterocyclic or non-heterocyclic aromatic ring, optionally substituted with at least one ester of a C 3 -C 20 alcohol, amine, amide, carboxyl, alkoxysilane, hydroxyl, carbonyl or acyl groups.
