Abstract

The present invention relates to kits and films formed from the kits which are useful as cosmetic or therapeutic agents, as well as methods of their use. The films and kits herein are particularly useful as polishes for mammalian nails. More particularly, the present invention relates to kits and films which, when applied to mammalian nails exhibit long wear.

Claims

1. A nail polish kit for mammalian nails comprising:

(I) a basecoat composition comprising;

(a) from about 0.1 % to about 20%, by weight of the composition, of a water-insoluble film-forming polyurethane polymer; and

(b) a liquid diluent comprising;

(i) from about 10% to about 90%, by weight of the composition, of a volatile organic solvent; and

(ii) at least about 8%, by weight of the composition, water; and

(II) a topcoat composition comprising;

from about 0.1% to about 40%, by weight of the composition, of a water-insoluble, film-forming, water-borne polymer selected from the group consisting of polyacryls, polymethacryls, styrene-acryl copolymers, and mixtures thereof; and

at least about 30%, by weight of the composition, water.

2. A kit according to claim 1 wherein the polymer of the topcoat composition is a cross-linked polymer.

3. A kit according to claim 2 wherein the topcoat composition further comprises from about 0.1% to about 30% of a coalescent.

4. A kit according to claim 3 further comprising a midcoat composition comprising a liquid diluent and a water-insoluble, solvent-borne, film-forming polymer selected from the group consisting of cellulosic polymers, polyurethanes, polyacryls, polymethacryls, polysiloxanes, and mixtures thereof.

5. A kit according to claim 1 further comprising a midcoat composition comprising a liquid diluent and a water-insoluble, solvent-borne, film-forming polymer selected from the group consisting of cellulosic polymers, polyurethanes, polyacryls, polymethacryls, polysiloxanes, and mixtures thereof.

6. A kit according to claim 5 wherein the midcoat composition comprises from about 10% to about 16% of the film-forming polymer, the liquid diluent comprises from about 60% to about 85% of a volatile organic solvent, and further comprises from about 5% to about 13% of a plasticizer.

8. A method of coating mammalian nails with a kit according to claim 1, wherein the method comprises the steps of:

(i) applying the basecoat composition contiguously to the nail;

(ii) removing sufficient liquid diluent from the basecoat composition to form a substantially dry layer;

(iii) applying the topcoat composition to the nail; and

(iv) removing sufficient liquid diluent from the topcoat composition to form a substantially dry layer.

9. A method of coating mammalian nails with a kit according to claim 5, wherein the method comprises the steps of:

(i) applying the basecoat composition contiguously to the nail;

(ii) removing sufficient liquid diluent from the basecoat composition to form a substantially dry layer;

(iii) applying the midcoat composition to the nail;

(iv) removing sufficient liquid diluent from the midcoat composition to form a substantially dry layer;

(v) applying the topcoat composition to the nail;

(vi) removing sufficient liquid diluent from the topcoat composition to form a substantially dry layer.

10. A kit according to claim 1 further comprising information that use of the kit provides one or more long wear benefits selected from the group consisting of resistance to chipping, resistance to peeling, and resistance to denting.

11. A kit according to claim 5 further comprising information that use of the kit provides one or more long wear benefits selected from the group consisting of resistance to chipping, resistance to peeling, and resistance to denting.

13. A kit according to claim 1 wherein the basecoat composition further comprises a water-insoluble, film-forming polymer selected from the group consisting of polyacryls, polymethacryls, styrene-acryl copolymers and mixtures thereof.

19. A kit according to claim 13 wherein the topcoat composition further comprises a film-forming polymer selected from the group consisting of polyacryls, polymethacryls, styrene-acryl copolymers, and mixtures thereof.

20. A kit according to claim 1 wherein the volatile organic solvent of the basecoat composition is selected from the group consisting of alcohols, esters, and mixtures thereof.

7. A nail polish kit for mammalian nails comprising:

(I) a basecoat composition comprising;

(a) from about 0.1% to about 20%, by weight of the composition, of a water-insoluble, film-forming polyurethane polymer; and

(b) a liquid diluent comprising;

(i) from about 10% to about 90%, by weight of the composition, of a volatile organic solvent; and

(ii) at least about 8%, by weight of the composition, water; and

(II) a topcoat composition comprising from about 1% to about 50%, by weight of the composition, of a water-insoluble, solvent-borne, film-forming polyurethane polymer; and

from about 50% to about 99%, by weight of the composition, of a volatile organic solvent.

14. A kit according to claim 7 wherein the basecoat composition further comprises a water-insoluble, film-forming polymer selected from the group consisting of polyacryls, polymethacryls, styrene-acryl copolymers, and mixtures thereof.

16. A kit according to claim 7 wherein the topcoat composition further comprises a cellulosic film-forming polymer.

17. A kit according to claim 7 wherein the topcoat composition further comprises a film-forming polymer selected from the group consisting of polyacryls, polymethacryls, styrene-acryl copolymers, and mixtures thereof.

18. A kit according to claim 14 wherein the topcoat composition further comprises a cellulosic film-forming polymer.

21. A kit according to claim 7 wherein the volatile organic solvent of the basecoat composition is selected from the group consisting of alcohols, esters, and mixtures thereof.

12. A nail polish kit for mammalian nails comprising:

(I) a basecoat composition comprising;

(a) from about 0.1% to about 20%, by weight of the composition, of a water-insoluble, film-forming polyurethane polymer; and

(b) a liquid diluent comprising;

(i) from about 10% to about 90%, by weight of the composition, of a volatile organic solvent; and

(ii) at least about 8%, by weight of the composition, water; and
