- 8. The coloring composition according to claim 1, wherein said dye vehicle is selected from the group consisting of water, alcohol, and mixtures thereof.
- 9. The coloring composition according to claim 8, wherein said water is present in an amount of from about 30 wt. % to about 90 wt. % by weight of the total coloring composition.
- 10. The coloring composition according to claim 8, wherein said dye vehicle comprises from 0% to about 50% alcohol.
- 11. The coloring composition according to claim 1, further comprising a starch.
- 12. The coloring composition according to claim 11, wherein said starch is present in an amount of from about 2% to about 30% by weight of said coloring composition.
- 13. The coloring composition according to claim 1, further comprising a film forming resin selected from the group consisting of water-soluble resin and alkali-soluble resin.
- 14. A marker ink comprising:
- (a) a colorant selected from the group consisting of a polymeric dye, a pigment, and mixtures thereof;
- (b) water; and
- (c) an anionic dyeblocker in an amount sufficient to enhance the fugitivity of said composition from skin.
- 15. The marker ink according to claim 14, wherein said anionic dyeblocker is an aromatic organic sulfonate.
- 16. The marker ink according to claim 15, wherein said aromatic organic sulfonate is selected from the group consisting of a sulfonated phenol-formaldehyde condensation product, a sulfonated naphthalene condensation product, and mixtures thereof.
- 17. A marking instrument containing an ink, said ink comprising:
- (a) a colorant selected from the group consisting of a polymeric dye, a pigment, and mixtures thereof;
- (b) water; and
- (c) an anionic dyeblocker in an amount sufficient to enhance the fugitivity of said composition from skin.
- 18. The marking instrument according to claim 17, wherein said anionic dyeblocker is an aromatic organic sulfonate.
- 19. The marker ink according to claim 18, wherein said aromatic organic sulfonate is selected from the group consisting of a sulfonated phenol-formaldehyde condensation product, a naphthalene condensation product, and mixtures thereof.
- 20. A method of imparting skin and fabric fugitivity to a composition containing a colorant, comprising adding to said composition an aromatic organic sulfonate selected from the group consisting of a sulfonated phenol-formaldehyde condensation product, a sulfonated naphthalene condensation product, and mixtures thereof in an amount sufficient to enhance the fugitivity of said composition from skin.
- 21. An aqueous ink composition suitable for use in a marking instrument, comprising:
- (a) polymeric dye in an amount of from about 2 wt. % to about 30 wt. % by weight of the aqueous ink composition; and,
- (b) an aromatic organic sulfonate in an amount of from about 1% to about 15% by weight of the aromatic organic sulfonate in said aqueous ink composition.
- 22. The aqueous ink composition according to claim 21, further comprising a film forming component selected from the group consisting of a starch, a water-soluble resin, a alkali-soluble resin, and mixtures thereof in an amount of from about 2% to about 30% by weight of the aqueous ink composition.
