Embodiment 1

[0111] An aqueous composition was prepared with 10% Pigment 1. 0.5 g of this aqueous solution are applied to 1 g of a clean, dry strand of natural hair having a shade height of 4, according to the natural shade described by C. Zviak, Ed. Masson in "Science des Traitements Capillaires", 1988, p. 278 A classification which corresponds to shades of natural maroon.

[0112] The locks were then dried under a hood and then moistened with 0.5 g of water. 0.5 g of a composition comprising the coloring medium described above and 10% by weight of a cyanoacrylate monomer was applied to the damp lock of hair.

[0113] After 15 minutes of exposure, the locks were blow-dried for 2 minutes.

[0114] The lock of hair obtained was colored orange and the color obtained was maintained for at least six shampoos.

Embodiment 2

[0116] A composition was prepared comprising 10% Pigment 2 in the coloring medium described above. Cyanoacrylate monomer was added to the composition to give a final monomer concentration of 10% by weight. 0.5 g of the composition was applied to a lock of clean, dry natural hair of shade level 4 which had been moistened with 0.5 g of water.

[0117] After 15 minutes of exposure, the locks were blow-dried for 2 minutes. Get blonde hair.

[0118] The coloring thus obtained is very shampoo-resistant.

Embodiment 3

[0119] Embodiment 3 methyl heptyl cyanoacrylate monomer

[0120] Prepare the following compositions:

[0121] DC 1501 Fluid 40g

[0122] DC 245 Fluid 40g

[0123] Prestige Bronze Brown Iron Oxide / Mica Mother of Pearl

[0124] Eckart 10g

[0125] Methylheptyl cyanoacrylate 10g from Chemence

[0126] 0.5 g of the composition is applied to a lock of 1 g of clean, damp hair. After waiting 15 minutes, the strand of hair was blow-dried for 2 minutes with a hair dryer.

[0127] The hair is colored and the color obtained is resistant to shampooing.

Abstract

This coloring composition contains at least one pigment and at least one cyanoacrylate monomer of formula (I) (R is an alkyl or an alkoxyalkyl) in a suitable coloring medium. The composition develops the coloration to the extent of being visible on the dark keratin material.

Description

technical field [0001] The invention relates to a composition for coloring keratinous substances, in particular keratinous fibers such as hair, and to a method for coloring keratinous substances, said composition comprising at least one pigment and at least one specific electrophilic monomer. Background technique [0002] In the field of coloring of keratin fibers, it is known to color keratin fibers by various techniques, either from direct dyes and pigments for a non-permanent coloration, or from dye precursors for a permanent coloration. [0003] Non-permanent coloring and direct coloring involve the coloring of keratin fibers with coloring compositions comprising direct dyes. These dyes are colored or pigmented molecules that have an affinity for keratin fibers. It is applied to the keratin fibers for the time required to obtain the desired coloration and then washed off. [0004] The conventional dyes used are in particular dyes of the nitrobenzene, anthraquinone, nit...
