Preglued nail decorative accessory and making method thereof

Abstract

An ornamental accessory for a fingernail comprises an overlay having a reusable pressure-sensitive adhesive layer pre-applied to a bottom surface 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 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 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 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 fixed to the overlay. The pressure-sensitive adhesive layer is reactivated by adding an aqueous solution to the dried aqueous copolymer emulsion.

AI Technical Summary

Benefits of technology

This technology makes for an easier way to attach something like a fake frog onto their natural nails instead of being permanently fixed into them afterwards. Instead of having permanent stickers made from plasters, this new type of material has two layers - one contains bubbles at regular intervals along its length – allowing easy removal when needed while still providing strong enough bond strength between itself and any other thing they are trying to fix themselves securely over time.

Problems solved by technology

Technic problem addressed in this patented technical solution described in the previous paragraph relates to improving nail ornament designs without compromising their effectiveness due to poor adhesions caused during application process steps such as cleanup after applying glue before drying out. Existing solutions involve adding extra components (such as films) onto the surface of the artificial nails themselves but they may also require multiple applications per day.
