Claims
- 1. A process for dyeing hair comprising applying to hair a dye composition containing (i) at least one anionic polydye of the formula ##STR17## wherein R.sup.1 is a chromophore; R.sup.2 is H, acyl, or --R.sup.1 (X.sup.2).sub.n ; X.sup.2 is an anionic group; n is 0 or 1, and n.sup.1 and n.sup.2 are numbers designating degree of polymerization, and (ii) a polymeric compound of the formula ##STR18## wherein R.sup.3 is epoxypropyl or dimethylaminohydroxypropyl; X.sup.4 is an anionic group, and n.sup.3 is a number designating degree of polymerization, said anionic polydye (I) and said polymeric compound (II) each being present in said composition at concentrations effective to interactively form an amount of a water-insoluble polymeric complex sufficient to be deposited on the hair as an adhering film when the composition is applied to the hair, whereby the hair is dyed.
- 2. The process according to claim 1 wherein said dye composition also contains a surfactant which ensures the essentially complete precipitation of said complex.
- 3. The process according to claim 2 wherein the components of said dye composition are present in said dye composition at levels within the following ranges:
- ______________________________________ % by Wt. Based on Total Wt. of Dye Composition______________________________________(1) Anionic poyldye (I) from about 0.1 to about 0.2%(2) Cationic polymer (II) from about 0.5% to about 1.0%(3) Surfactant to about 1.0%______________________________________
- 4. The process according to claim 3 wherein the chromophore R.sup.1 is selected from the group consisting of nitrobenzenes, anthrapyridines, anthraquinones, azo dyes, nitroanilines, xanthene, phthalocyanine, benzanthrone and naphthalimide dyes; the surfactant is an amphoteric surfactant, and n is 1.
- 5. The process according to claim 4 wherein said amphoteric surfactant is coco imidazoline.
- 6. The process according to claim 1 further comprising forming said dye composition just prior to its application to the hair by mixing a liquid dye vehicle containing said anionic polydye (I) with a liquid vehicle containing said polymer (II).
- 7. The process according to claim 6 wherein said liquid dye vehicle contains a plurality of anionic polydyes.
- 8. A composition for dyeing hair comprising (A) an effective hair dyeing amount of at least one anionic polydye of the formula ##STR19## wherein R.sup.1 is a chromophore; R.sup.2 is H, acyl, or --R.sup.1 (X.sup.2).sub.n ; X.sup.2 is an anionic group; n is 0 or 1, and n.sup.1 and n.sup.2 are numbers designating degree of polymerization, and (B) a polymeric compound of the formula R1 ? ? ##STR20## wherein R.sup.3 is epoxypropyl or dimethylaminohydroxypropyl; X.sup.4 is an anionic group, and n.sup.3 is a number designating degree of polymerization, said anionic polydye (I) and said polymeric compound (II) each being present in said composition at concentrations effective to interactively form an amount of a water-insoluble polymeric complex sufficient to be deposited on the hair as an adhering film when the composition is applied to the hair, whereby the hair is dyed.
- 9. The composition according to claim 8 further comprising a surfactant which ensures the essentially complete precipitation of said complex.
- 10. The composition according to claim 9 wherein said surfactant is an amphoteric surfactant.
- 11. The composition according to claim 8 in which X.sup.2 is an anionic group and n is 1.
- 12. A two-part composition for dyeing hair comprising as a first part a liquid vehicle including a dye and as a second part a liquid vehicle including a polymer, said first and said second parts being suitable for admixture just prior to use to form a hair dye composition, the dye in said first part being an anionic polydye of the formula ##STR21## wherein R.sup.1 is a chromophore; R.sup.2 is H, acyl, or --R.sup.1 (X.sup.2).sub.n ; X.sup.2 is an anionic group; n is 0 or 1, and n.sup.1 and n.sup.2 are numbers designating degree of polymerization and the polymer in said second part being a polymeric compound of the formula ##STR22## wherein R.sup.3 is epoxypropyl or dimethylaminohydroxypropyl; X.sup.4 is an anionic group, and n.sup.3 is a number designating degree of polymerization, said anionic polydye (I) in said first part and said polymeric compound (II) in said second part, when admixed, being present in said hair dye composition at concentrations effective to interactively form an amount of a water-insoluble polymeric complex sufficient to be deposited on the hair as an adhering film when the composition is applied to the hair, whereby the hair is dyed.
- 13. The two-part composition according to claim 12 wherein said liquid dye vehicle also contains a surfactant which ensures the essentially complete precipitation of said complex in the hair dye composition.
- 14. The composition according to claim 12 wherein X.sup.2 is an anionic group and n is 1.
- 15. The composition of claim 13 wherein said surfactant is an amphoteric surfactant.
