Silylated p-phenylenediamine or p-aminophenol derivatives (I) are new. <??>Compounds of formula (I) and their salts are new: <??>A = OH or NH2; <??>R1, R2 = H, 1-8C alkyl, 1-6C hydroxyalkyl or YB, or NR1R2 is a 4- to 7-membered heterocycle optionally substituted with 1-3C alkyl, OH, NH2 or ZB; <??>R3, R4 = H, 1-4C alkyl, 1-4C alkoxy, halo or ZB; <??>Y = a 1-8C (un)saturated hydrocarbon chain optionally interrupted with O, S or NR; <??>Z = Y, OY or (NR)Y; <??>R = H or 1-4C alkyl; <??>B = SiR5R6R7; <??>R5-R7 = 1-4C alkyl or phenyl; <??>provided that R1 and R2 are H when A is OH and that at least one of R1-R4 is YB or ZB. <??>Independent claims are also included for: <??>(1) an oxidation dye composition comprising a developer of formula (I); <??>(2) a method for dyeing keratinic fibers, comprising applying the composition of (1) and developing the color with an oxidizing agent; <??>(3) a kit comprising a compartment containing the composition of (1) and a compartment containing an oxidizing composition; <??>(4) a colored product produced by oxidizing the composition of (1). |
