The combination of a fingernail having adhered to the surface thereof and providing a smooth surface, a coating formed from a polymer of an acrylic monomer, a hydrocarbon solvent and a wax. The acrylic monomer can be acrylic or methacrylic. The solvent can be an alkane or alkene having 6 to 8 carbon atoms. The wax can be paraffin. Also included into the composition can be added an antioxidant and/or thickening agent. The novel method which comprises applying to a fingernail a liquid composition containing an acrylic monomer, a hydrocarbon solvent, and a wax, and allowing the composition to dry to form an adherent polymeric coating. The fingernail may be the natural fingernail alone, or together with an artificial fingernail extension.

Scuptured nails

An artificial fingernail or tip formed of polymer plastic contains light diffusing means located only within the front distal portion, the light diffusing means including, a plurality of minute depressions within and throughout at least the upper surface of said polymer strip for providing a textured roughened surface to obtain a natural appearing contrast between the front distal portion and the back proximal portion of the nail. In an additional aspect, the appearance is further enhanced by inclusion of slight pigmentation of the plastic material.

Artificial fingernail

A highly tacky continuous, generally self-sustaining film of pressure sensitive adhesive (formed by combining two pre-formed pressure sensitive adhesive films) without any imbedded supporting film uniquely useful for the bonding of two variably curved surfaces in superposed relationship, especially where said two surfaces are a natural fingernail and a superimposed plastic artificial fingernail, the minimum thickness of said film being at least 8 mils, the maximum thickness being about 12 mils, and the minimum initial adhesion to low energy plastic surfaces of said adhesive being at least 9 as defined by 3M Guide at page 16. In the method of mounting and adhering an artificial nail to a natural finger which includes the steps of: (1) providing an adhesive tab for covering a substantial portion of the area of the outside surface of the natural nail upon which it is desired to mount an artificial nail; (2) providing a superposed plastic artificial fingernail; (3) securing one side of said tab to the outer surface of said natural nail; or the inner surface of said artificial nail; (4) aligning and pressing said artificial nail, said tab, and said natural nail to adhere the artificial nail to the natural nail in superposed relationship; the improvement wherein the adhesive tab comprises: a highly tacky continuous, generally self-sustaining film of pressure sensitive adhesive without any imbedded supporting film uniquely useful for the bonding of two variably curved surfaces in superposed relationship, especially where said two surfaces are a natural fingernail and a superimposed plastic artificial fingernail, the minimum thickness of said film being at least 8 mils, and the minimum initial adhesion to low energy plastic surfaces of said adhesive being at least 9 as defined by 3M Guide at page 16, said self sustaining film being formed by combining two-pre-formed pressure sensitive adhesive films.
