Abstract
The present invention relates to a composition intended for dyeing keratin fibres, in particular of human keratin fibres such as the hair, comprising one or more acrylate-functionalized polymers and one or more silicones chosen from silicones functionalized with one or more mercapto groups, amino silicones, and mixtures thereof, and one or more pigments.
Claims19
A composition comprising:
- (i) one or more acrylate-functionalized polymers, wherein the one or more acrylate-functionalized polymer(s) is or are chosen from acrylate-functionalized silicone homopolymers and acrylate-functionalized silicone copolymers,
- (ii) one or more silicones functionalized with one or more mercapto groups, wherein the one or more silicone(s) functionalized with one or more mercapto groups is or are chosen from the compounds of the following formulae:
- in which R1 denotes a saturated or unsaturated, linear or branched, optionally cyclic, hydrocarbon-based chain comprising from 1 to 100 carbon atoms, optionally interrupted with a heteroatom chosen from N, O, S and P,
- R2 denotes an alkyl group containing from 1 to 6 carbon atoms or an alkoxy group containing from 1 to 6 carbon atoms,
- n ranges from 0 to 132,
- n1 ranges from 1 to 132, and
- m ranges from 1 to 132, and
- (iii) one or more pigments.
