摘要

The subject of the present invention is compounds of the following formula (I): wherein R 1 and R "1 represent -CH 3; -CH 2 O 2; -CHO; -COOR 10, R 10: H, aklyl; -CONR 11 R 12, R 11, R 12: H, W; at least one of the radicals being different from H; -CH 2 NR 13 R 14, R 13, R 14: H, W, at least one of the radicals being different from H; -COR 15, R 15: alkyl, R 2 and R "2 represent H; -CH3; -CH2OZ; -COR20, R20: alkyl; -COOR21, R21: H, alkyl; -CONR22R23, R22, R23: H, W, at least one of which is different from H; -CH2NR24R25, R24 and R25: H, W, at least one of which is different from H; - C (OH) R 26 R 27, R 26, R 27: alkyl, phenyl, unsubstituted benzyl; R3 and R "3 represent: -OZ; -CH3; -NR31R32, R31 and R32: H, W, at least one of which is different from H; alkylthio; R'3 may additionally be H; R4 and R; "4 represent H; an alkyl; a sugar pattern; -COR40, R40: alkyl; -COOR41, R41: alkyl; -CONR42R43, R42, R43: H, W; -Si (R44) 3 R44: alkyl; Z is H; alkyl; sulfonic, alkylsulphonate, phenylsulphonate or alkylphenylsulphonate group; a -COR 2 group with R 2: alkyl, sugar unit; W represents a hydrocarbon radical C1-C40, linear, branched and / or cyclic, saturated, unsaturated, aromatic or otherwise, optionally substituted; and / or optionally interrupted by one or more heteroatoms and / or groups comprising; n integer varies from 0 to 5; Exclusions of formula (I): * when R4 represents a sugar unit, a (C1-C4) alkylcarbonyl, a mono- or di (C1-C4) alkylaminocarbonyl, then R2 does not represent an alkoxy (C1- C2) carbonyl, hydroxycarbonyl, -CH2OH, R2 also does not represent H when R4 is a sugar; when R4 is H and R1 is -CH3, -CH2OH, then R2 is not H, -CH3, -COOH, -COOCH3. The invention also relates to a composition comprising such compounds and a process for dyeing keratinous fibers implementing it.
