Also, finishing compounds may be used to clean the surface of the uv curable coatings resulting in a high-gloss shine. The methods of applying uv-radiation curable nail coatings, bond-enhancing compounds, and finishing compounds to artificial nail-tips and natural nail are also discussed.

A system and method for creating precision fit artificial fingernails is disclosed. Specifically, a system is disclosed that utilizes a scanned and digitized nail surface to form a precision fit three dimensional digitized artificial nail object that can be used to direct a machining device that either creates an artificial fingernail from blank stock, or to machine a custom mold that can be used to make multiple artificial fingernails having the same shape.

An artificial fingernail has an outer layer made of silicone allowing the nail to maintain its form when not in contact with objects but permitting the nail to flex upon contact with objects and bend back to its original shape after contact. Accordingly, the wearer can simultaneously look attractive and engage in vigorous exercise or other vigorous activities such as scrubbing, cleaning, cooking etc. The artificial fingernail may also be combined with jewelry and may be molded with cut-out designs.

Provided is a preformed artificial nail designed to conform to the wearer's natural fingernail. The artificial nail includes an elongated nail body (110) that extends between a proximate edge (120) intended to abut against the cuticle and a distal edge (122) intended to extend beyond the wearer's fingertip. To allow the nail body to conform to the curve of the natural fingernail between the sides, the thickness of the nail body increases from the proximate edge to the distal edge. The relatively thinner proximate edge provides that region of the nail body with an inherent flexibility that allows the nail body to deflect and conform to the natural fingernail. The relatively thicker distal edge provides that region of the nail body with an inherent rigidity and, relatedly, additional strength to the portion of the nail body intended to extend beyond the fingertip.

The present application relates to artificial nail tips, particularly artificial nail tips that have an attachment area with an axial curvature and two cutout portions which provide a comfortable and conforming fit to a variety of natural nails while maintaining structural integrity and minimizing damage to the natural nail. The axial curvature of the attachment area of the nail tips is of a single radius design. The cutout portions of the nail tips are on both sides of the attachment portion of the nail tips, leaving a center attachment area narrower and thinner than the remaining nail tip. The attachment area of the nail tip is in a shape that allows for conformation to all natural nails, regardless of the length or curvature of the natural nail while maintaining the strength of the natural nail and minimizing damage to the natural nail. The shape of the attachment area of the nail tip allows it to deform to the natural nail without losing structural integrity.

Limited shelf life due to pigment settling and the formation of hard packs in pigmented UV curable nail gels is solved by the present invention which describes a composition, method, and use of a UV curable, thixotropic, radiation curable, low viscosity gel comprised of a formulation containing thixotropic additive(s) and in some cases dispersants for additional dispersion stability. The thixotropic pigmented gel has prolonged shelf life and long time storage at ambient conditions. It also contains negligible amounts of unreactive solvent. The thixotropic additive also changes the rheological properties of the gel, which allows the nail gel to be easily applied to nails at a lower viscosity due to shear thinning.

Disclosed is an artificial nail attached with an adhesion sticker having glitter, which is easily wearable and recyclable with an improved outer appearance and high adhesive strength of the sticker. As for the artificial nail for use in nail art, the adhesion sticker having a first sheet, a second sheet and a third sheet compressed together, each of which is formed by silkscreen-printing acrylic emulsion glue, is attached to a lower back end of the artificial nail. Also, the second sheet includes 4-8 wt % of the glitter based on 100 wt % of the acrylic emulsion glue. Further, the artificial nail is provided in the state of the adhesion sticker being attached to the back surface thereof, thus providing more conveniences for the user. Furthermore, after the use of the artificial nail, only the sticker attached to the back surface of the artificial nail is replaced with new ones, thereby recycling the artificial nail. In addition, the glitter is added to the adhesion sticker, whereby the improved outer appearance of the artificial nail is achieved and the generation of air bubbles in the sticker is reduced, therefore increasing the adhesive strength of the sticker.
