Oxidation dye composition, useful for dyeing keratin fibers, especially human hair, comprises 2,4-dichloro-3-aminophenol and a bis-p-phenylenediamine or bis-p-aminophenol compound

摘要

Oxidation dye composition for dyeing keratin fibers comprises: (1) 2,4-dichloro-3-aminophenol; and (2) a bis-p-phenylenediamine or bis-p-aminophenol compound (I). Oxidation dye composition for dyeing keratin fibers comprises: (1) 2,4-dichloro-3-aminophenol; and (2) a compound of formula (I). R1, R2 = OH or NR'R; R', R = H, 1-4C alkyl or 1-4C hydroxyalkyl or form part of X; X = a bond or a 2-14C alkylene or cycloalkylene group optionally interrupted by N-containing groups and/or heteroatoms and optionally substituted with OH or 1-8C alkoxy; R9, R10 = H, halo, 1-4C alkyl, 1-4C monohydroxyalkyl, 2-6C polyhydroxyalkyl, 1-4C aminoalkyl or a bond to X; and R3-R8 = H, 1-4C alkyl or a bond to X. Provided that (I) has at least one amino group with at least one H atom. An Independent claim is also included for a method for dyeing keratin fibers, comprising applying the above composition to the fibers, rinsing it off after allowing it to act, and optionally shampooing the fibers.
