Abstract

The invention relates to a method of imparting color onto keratinous substrates involving contacting said substrate with a composition comprising: at least one triarylmethane dye molecule chosen from polymeric triarylmethane dye molecules, copolymeric triarylmethane dye molecules, oligomeric triarylmethane dye molecules, and mixtures thereof; at least one film forming agent; and at least one solvent; and irradiating said substrate with a flash of light.

Claims

1. A process for imparting color onto a keratinous substrate comprising:

(a) providing a keratinous substrate;

(b) providing a cosmetic composition containing;

(i) at least one triarylmethane dye molecule chosen from polymeric triarylmethane dye molecules, copolymeric triarylmethane dye molecules, oligomeric triarylmethane dye molecules, and mixtures thereof;

(ii) at least one film forming agent; and

,

(iii) at least one solvent,

(c) contacting the keratinous substrate with the cosmetic composition to form a treated keratinous substrate; and

,

(d) irradiating the treated keratinous substrate with a flash of light.

2. The process of claim 1, wherein said at least one triarylmethane dye molecule is an oligomeric triarylmethane.

3. The process of claim 1 wherein said at least one triarylmethane dye molecule is chosen from Basic Violet Acetate, Basic Blue Acetate, and mixtures thereof

4. The process of claim 1, wherein said at least one triarylmethane molecule is present in an amount ranging from about 0.05% to about 2% by weight, relative to the total weight of said cosmetic composition.

5. The process of claim 1, wherein said at least one triarylmethane molecule is present in an amount ranging from about 0.075% to about 1% by weight, relative to the total weight of said cosmetic composition.

6. The process of claim 1, wherein said at least one film forming agent is chosen from anionic, non-ionic, cationic, and amphoteric agents.

7. The process of claim 6, wherein said at least one film forming agent is a di-block, tri-block, multi-block or radial copolymer.

8. The process of claim 1, wherein said at least one film forming agent is an imide based copolymer.

9. The process of claim 8, wherein said imide based copolymer is Polyimide-1 or Isobutylene/Ethylmaleimide/Hydroxyethylmaleimide Copolymer.

10. The process of claim 1, wherein said film forming agent is a sulfonate based copolymer.

11. The process of claim 10, wherein said sulfonate based copolymer is chosen from Acrylamide/Sodium Acryloyldimethyltaurate/Acrylic Acid Polymer, sodium polystyrene sulfonate and polyester-5.

12. The process of claim 1, wherein said at least one film forming agent is present in an amount ranging from about 1% to about 20% by weight, relative to the total weight of said cosmetic composition.

13. The process of claim 1 wherein said at least one solvent is selected from an organic solvent, water and a mixture thereof.

14. The process of claim 1, wherein said at least one solvent is ethanol.

15. The process of claim 1, wherein said at least one solvent is present in an amount ranging from about 75% to about 99% by weight, relative to the total weight of said cosmetic composition.

16. The process of claim 1, further comprising a surfactant.

17. The process of claim 16, wherein said surfactant is chosen from magnesium laureth sulfate, sodium laureth sulfate, and mixtures thereof.

18. The process of claim 16, wherein said surfactant is present in an amount ranging from about 0.05% to about 5% by weight, relative to the total weight of the composition.

19. The process of claim 1, further comprising a propellant.

20. The process of claim 19, wherein said propellant is an Isobutane/Propane mixture.

21. The process of claim 19, wherein said propellant is present in an amount ranging from about 0.01% to about 6% by weight, relative to the total weight of the composition.
