Abstract:
A new class of chemical entities chosen from aminoindolizines of formula (I), acid addition salts thereof, and solvates thereof: their use for dyeing keratin fibers, including human keratin fibers such as the hair; dyeing compositions comprising such chemical entities; and to kits containing compositions comprising those chemical entities.
Abstract:
The subject of the present invention is azo derivatives containing a pyrazolinone unit having the following formula (I), their mesomeric forms, their addition salts with an acid and their solvates and their use for dyeing keratin fibers. The subject of the invention is also a composition for dying keratin fibers comprising at least one azo derivative containing a pyrazolinone unit of formula (I) as direct dye, and the method for dyeing keratin fibers using this composition. The present invention makes it possible in particular to obtain chromatic colors that are resistant to the various attacks to which the hair may be subjected, in particular to shampoos and to light.
Abstract:
The present disclosure relates to a composition for coloring keratin fibers which comprises, in an appropriate dyeing medium, at least one compound chosen from leuco compounds of formula (I), azomethine dyes with a pyrazolinone unit of formula (II), their mesomeric forms, acid addition salts and solvates thereof: and dyeing methods and multicompartment devices for use thereof.

Abstract:
The present invention relates to a para-aminophenol compound of formula (I) the addition salts thereof with an acid and the solvates thereof, dye composition comprising the latter and a dyeing process.
Abstract:
The invention relates to 4-aminoindole derivatives of formula (I), and the addition salts thereof, mesomers thereof, isomers thereof and solvates thereof: and to their use for the oxidation dyeing of keratin fibers, and in particular of human keratin fibers such as the hair. The present invention makes it possible to achieve dark shades, natural shades and dark natural shades. The present invention also makes it possible to obtain powerful, chromatic, aesthetic, sparingly selective coloration of keratin fibers in varied shades, which is resistant to the various attacking factors to which the hair may be subjected. In particular, when the 4-aminoindole derivatives are combined with one or more heterocyclic oxidation bases, they make it possible to obtain a wide range of colors and coloration of keratin fibers that shows good chromaticity and good selectivity.

Abstract:
The subject of the present invention is dye composition for keratin fibres, comprising, in suitable dyeing medium, a coupler of formula (I) or addition salts thereof with an acid a particular cationic or noncationic aminopyrazolopyridine derivative. The composition of the present invention makes it possible in particular to obtain a colouring with varied, intense and/or chromatic, aesthetic and relatively nonselective shades which are highly resistant to the various attacks to which the hair may be subjected.
