<p>An ornamental accessory (10) for a fingernail comprises an overlay (11) having a reusable pressure-sensitive adhesive layer (12) pre-applied to a bottom surface (14) thereof for application and bonding to the wearer's natural nail, and a method of making the same. The adhesive formulation is a copolymer of acrylic ester and vinyl acetate formed from an aqueous acrylic copolymer emulsion. The bottom surface of the overlay (11) to which the adhesive is applied is textured to enhance adhesion of the adhesive layer. A method for forming a pre-glued ornamental fingernail accessory (10) includes the steps of forming an overlay having the shape and size of a natural fingernail and applying an aqueous copolymer emulsion, as described above, to a bottom surface (14) of the overlay. The emulsion is allowed to cure whereby a substantial portion of the water in the emulsion is evaporated to form a reusable pressure-sensitive adhesive layer (12) fixed to the overlay (11). The pressure-sensitive adhesive layer (12) is reactivated by adding an aqueous solution to the dried aqueous copolymer emulsion. <IMAGE></p> |
