Process for dyeing keratin fibers by using derivatives of formula: STR1 where: R1 =H, lower alkyl or SiR11 R12 R13 ; R2 and R3, which may be identical or different, =H, alkyl, carboxyl, alkoxycarbonyl or --COOSiR11 R12 R13 ; R4 to R7, which may be identical or different, =H or an O--Z group, where Z=H, C1 -C20 alkyl, aralkyl, formyl, C2 -C20 acyl, C3 -C20 alkenyl, --SiR11 R12 R13, --P(O)(OR8)2, R8 OSO2 ; or a heterocycle which may contain a P(O)(OR8) or CR9 R10 group; with the reservation that at least two of R4 to R7 denotes OZ or form a ring, and that at least one of R4 or R7 represents OZ; R8 and R9 =H, lower alkyl; R10 =alkoxy, mono- or dialkylamino; R11, R12 and R13, which may be identical or different, are alkyl groups; or their alkali metal, alkaline-earth metal, ammonium and amine salts.
