Abstract: The invention relates to a dyeing composition comprising, in an appropriate dyeing medium, at least one electrophilic monomer and at least one pigment comprising at least one organic part. The composition in accordance with the invention makes it possible to obtain a visible and very chromatic coloration on a dark keratin material. In particular, in the case of dark keratin fibres, a very visible chromatic coloration is obtained without it being necessary to lighten or bleach the keratin fibres and, consequently, without physical degradation of the keratin fibres.

Abstract: Disclosed herein is a cosmetic composition for treating keratin materials, for example, keratin fibers such as the hair, comprising, in a cosmetically acceptable medium, at least one electrophilic monomer and at least one liquid crystal agent. Also disclosed is a method for cosmetically treating keratin materials comprising applying the cosmetic composition to the keratin materials.

Abstract: The present patent application relates to a process for the cosmetic treatment of keratin materials, including keratin fibers such as the hair. The process comprises applying the composition to the keratin materials, wherein the composition comprises, in a cosmetically acceptable medium, at least one electrophilic monomer and at least one non-silicone polymer, the non-silicone polymer being chosen such that the composition gives, after drying, a film with a maximum peel force of greater than 1 newton. The application also relates to the composition.

Abstract: The present disclosure relates to a dyeing composition comprising, in an appropriate dyeing medium, at least one pigment and at least one electrophilic cyanoacrylate monomer of formula (I) in which R is chosen from alkyl radicals and alkoxyalkyl radicals. Dyeing kits comprising said compositions and processes using same are also disclosed.

Abstract: Disclosed is a dyeing keratin materials comprising applying to said materials at least one composition comprising, in a suitable dyeing medium, at least one electrophilic monomer, at least one colored pigment and at least one pigment that has a refractive index greater than the at least one colored pigment.

Abstract: Disclosd herein is a film-forming composition for the cosmetic treatment of keratin materials comprising, in a cosmetically acceptable medium, at least one electrophilic monomer and at least one non-silicone polymer, such that the film obtained from the composition by drying at room temperature and with a relative humidity level of about 50% has a Young's modulus of between 100 and 2000 MPa, measured for a thickness of 0.5 mm and with a tensile speed of 20 mm/min.

Abstract: The present disclosure relates to methods for treating keratin materials, including keratin fibers such as the hair, of a composition comprising, in a cosmetically acceptable medium, at least one electrophilic monomer and microparticles or nanoparticles.

Abstract: Disclosed herein is a cosmetic composition comprising at least one electrophilic monomer and at least one non-reducing organic acid containing from 1 to 12 carbon atoms in a cosmetically acceptable anhydrous medium, and its use for the cosmetic treatment of the hair. Also disclosed herein is a method of cosmetic treatment of the hair which employs the composition.

Abstract: The present invention relates to a composition for dyeing keratin fibers comprising at least one compound bearing at least one amine function, at least one pigment and at least one chemical coupling agent, to the processes for dyeing keratin fibers, using this compound bearing at least one amine function, this pigment and this chemical coupling agent, and also to the use of this compound bearing at least one amine function, of this pigment and of this chemical coupling agent for dyeing keratin fibers. In at least one embodiment, the present invention allows the production of a coloration that is visible on a dark support without it being necessary to lighten or bleach the keratin fibers, and that shows good resistance to the various attacking factors to which the hair may be subjected, in particular to shampoos and to rubbing.

Abstract: The present disclosure relates to compositions for dyeing keratin fibers comprising at least one pigment, at least one polymer PA bearing at least one functional group A, and at least one polymer PB bearing at least one functional group B, wherein the functional groups A and B can form covalent bonds together; to processes for dyeing keratin fibers with the compositions as disclosed herein, and also to the use of this pigment and of these polymers for dyeing keratin fibers in a color-fast manner.
