Process for dyeing keratin fibres with a monohydroxyindole associated with an iodide and hydrogen peroxide

-

, (2008/06/13)

Process for dyeing keratin fibres consisting in applying on these fibres a composition (A) containing at least one indole colorant of formula: STR1 where R1 =H or C1 -C4 alkyl; R2 and R3, which may be identical or different, denote H, C1 -C4 alkyl, carboxyl or alkoxycarbonyl; or a salt or a precursor of a compound (I), associated, either with iodide ions, or with H2 O2 ; application of composition (A) being preceded or followed by the application of a compound (B) which contains, either H2 O2 at a pH of 2 to 12 when (A) contains iodide ions, or iodide ions at a pH of 2 to 11 when (A) contains H2 O2. This process allows particularly powerful and resistant dyes to be made.
