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. When applied to mammalian nails, the present kits provide films exhibiting Peak Adhesive Strengths of greater than about 15 g/mm and exhibiting a Toughness Value of greater than about 1.2 MPa or a Wear Value of greater than about 1000 (MPa)2. The present invention further relates to methods of coating mammalian nails with kits and films formed from the kits which exhibit Peak Adhesive Strengths of greater than about 15 g/mm and exhibit Toughness Values of greater than about 1.2 MPa or Wear Values of greater than about 1000 (MPa)2.

20. A method of coating mammalian nails with a nail polish film, the film comprising two or more layers, wherein the method comprises the steps of:
-
(a) applying a basecoat composition contiguously to the nail, wherein the basecoat composition comprises a film-forming polymer and a liquid diluent; (b) removing sufficient liquid diluent from the basecoat composition to form a substantially dry basecoat; (c) applying a topcoat composition to the nail, wherein the topcoat composition comprises a film-forming polymer and a liquid diluent; and (d) removing sufficient liquid diluent from the topcoat composition to form a substantially dry topcoat; wherein the film exhibits a Peak Adhesive Strength of greater than about 25 g/mm. - View Dependent Claims (21)
