Abstract
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.
