Abstract

An artificial nail includes: an artificial nail body having a shape corresponding to a shape of at least one portion of the natural nail, and including an upper surface provided to be away from a surface of the natural nail and a lower surface structured to face the surface of the natural nail; and an adhesive member disposed on a first surface of the lower surface of the artificial nail body. The lower surface of the artificial nail body includes the first surface overlapping the natural nail when attached to the surface of the natural nail and a second surface other than the first surface, and at least one portion of the first surface has a first roughness greater than a roughness of the second surface.

Claims (17)

1 . An artificial nail comprising:

an artificial nail body having an upper surface and a lower surface including a first surface and a second surface other than the first surface; and

an adhesive member disposed on the first surface of the lower surface of the artificial nail body,

wherein at least one portion of the first surface has a first roughness greater than a roughness of the second surface,

wherein the first surface of the lower surface includes a predetermined pattern which is not surface treated and having a roughness same as the roughness of the second surface,

wherein the first surface of the lower surface further includes a guide line pattern which is not surface treated and having a closed loop shape surrounding the predetermined pattern with a roughness same as the roughness of the second surface, and

wherein the closed loop guide line pattern serves as an alignment reference for positioning the artificial nail.

2 . The artificial nail according to claim 1 , wherein the artificial nail body includes a first end edge having a first thickness, and a second end edge opposite the first end edge having a second thickness different from the first thickness.

3 . The artificial nail according to claim 2 , wherein the second thickness is about four times thicker then the first thickness.

4 . The artificial nail according to claim 2 , wherein the first thickness is about 0.12 to 0.15 mm, and the second thickness is about 1 to 1.1 mm.

5 . The artificial nail according to claim 2 , wherein the artificial nail body has a shape gradually being thicker from the first end edge to the second end edge.

6 . The artificial nail according to claim 1 , wherein the upper surface has a second roughness greater than the roughness of the second surface by being surface treated.

7 . The artificial nail according to claim 6 , wherein the second roughness of the upper surface is lower than the first roughness of the first surface of the lower surface.

8 . The artificial nail according to claim 1 , wherein the predetermined pattern includes a pattern in the shape of a number, and the predetermined pattern is formed by being embossed or debossed.

9 . The artificial nail according to claim 1 , wherein the guide line pattern is formed by being embossed or debossed.

10 . The artificial nail according to claim 1 , wherein the adhesive member includes a photo-curable material.

11 . The artificial nail according to claim 10 , wherein an optical refractive index of the photo-cured adhesive member and an optical refractive index of the artificial nail body are substantially the same.
