The present disclosure relates to novel N-alkylpolyhydroxylated secondary para-phenylenediamines, to processes for preparing them, to compositions for dyeing keratin fibers, for example keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one such secondary para-phenylenediamine. The present disclosure also relates to processes for dyeing keratin fibers with the compositions according to the present disclosure, and to dyeing kits containing such compositions.

N-alkylpolyhydroxylated secondary para-phenylenediamines, dye compositions comprising them, processes, and uses thereof

The present disclosure relates to novel N-alkylhydroxylated secondary para-phenylenediamine compounds, to a composition for dyeing keratin fibers, for instance human keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one ortho- and/or meta-substituted N-alkylhydroxylated secondary para-phenylenediamine, to a process for dyeing keratin fibers comprising applying this composition, and also a dyeing 'kit.'

Ortho-and/or meta-substituted N-alkylhydroxylated secondary para-phenylenediamine compounds, compositions for dyeing keratin fibers comprising such compounds, and processes of dyeing therewith

The present disclosure relates to novel secondary para-phenylenediamines having a carboxyl group. The present disclosure further relates to a dye composition comprising at least one secondary para-phenylenediamine for dyeing keratin fibers, such as human hair, a process for preparing the composition, and a process and kit for dyeing keratin fibers using the composition.
