Description

  The present invention relates to an artificial nail adhesive sheet that allows an artificial nail to be easily attached to a raw nail.

  Nowadays, women are doing nail art on their raw nails for fashion, or putting on their nails on the raw nails.

  By the way, as a method of attaching the artificial nail to the raw nail, there is a method of attaching using an adhesive or a double-sided adhesive tape (for example, see Patent Document 1).

  However, in the method of attaching the artificial nail using an adhesive, it is necessary to hold the artificial nail until the adhesive is cured. It takes time to apply liquid and soak between the nail and raw nail to dissolve the adhesive.

On the other hand, in the method of attaching an artificial nail using a double-sided pressure-sensitive adhesive tape, after removing the release sheet on one adhesive surface of the double-sided pressure-sensitive adhesive tape and sticking one adhesive surface on the raw nail, The release sheet on the adhesive surface is removed, and the nail is attached to the other exposed adhesive surface, so the attachment / detachment of the artificial nail is shorter than when using an adhesive. When removing the release sheet, the fingertip touches a part of the adhesive layer, the fingertip sticks to the adhesive surface, and it is difficult to stick the double-sided adhesive tape to the raw nail well.

  The adhesive nail pressure-sensitive adhesive sheet according to claim 4 has a releasability with respect to the double-sided pressure-sensitive adhesive sheet material of the releasable protective film as compared with a releasability with respect to the double-sided pressure-sensitive adhesive sheet material of the release mount. When it is picked with a fingertip and peeled off from the release mount, the double-sided PSA sheet is surely detached from the release mount in a state where the double-sided PSA sheet is adhered to the releasable protective film side. Therefore, peeling from the release mount is easy.

  In the false nail pressure-sensitive adhesive sheet according to claim 5, the end edge of the double-sided pressure-sensitive adhesive sheet material and the releasable protective film opposite to the formation position of the peeling tongue piece is directed from the center in the width direction toward both sides in the width direction. Since it is chamfered into a convex R shape, the double-sided PSA sheet can be attached to one end of the raw nail with as little gap as possible by aligning the R part of the double-sided PSA sheet with the R part of the end of the raw nail. The artificial nail can be firmly fixed to the surface of the raw nail.
