## Abstract

A gel nail sticker includes a base film layer, and a pressure-sensitive adhesive layer, wherein the base film layer is a PET release film or release paper, and the pressure-sensitive adhesive layer is bonded to the bottom of a soft layer and connected with the base film layer; the soft layer is printed with at least one layer of screen printing color layer or shimmering powder layer by screen printing; a first crystal gel layer covers on the surface of the shimmering powder layer or the screen printing color layer, and a second crystal gel layer envelops the first crystal gel layer, the shimmering powder layer and the screen printing color layer, and is bonded to the soft layer and the pressure-sensitive adhesive layer. A manufacturing process for the gel nail sticker includes screen printing of the various layers.

## Claims

### Claim 1

A gel nail sticker, comprising:
a base film layer being a PET release film or release paper;
a pressure-sensitive adhesive layer connected with the base film layer;
a soft layer having a bottom bonded to the pressure-sensitive adhesive layer;
at least one screen printing color layer or at least one shimmering powder layer printed on the soft layer by screen printing;
a first crystal gel layer covering on the shimmering powder layer or the screen printing color layer; and
a second crystal gel layer enveloping the first crystal gel layer, the shimmering powder layer and the screen printing color layer, and bonded to the soft layer and the pressure-sensitive adhesive layer.

### Claim 2 (depends on 1)

The gel nail sticker of claim 1, wherein the shimmering powder layer is a layer of one or more materials selected from a group consisting of glitter powder, flashing powder, laser powder, camouflage powder, iridescence pigment and pearl powder, or a layer of tinsel or electrochemical aluminium layer.

### Claim 3 (depends on 1)

The gel nail sticker of claim 1, wherein the shimmering powder layer is printed on the soft layer by screen printing, at least one screen printing color layer is printed on the shimmering powder layer by screen printing, the first crystal gel layer covers on a top of the screen printing color layer, and the crystal gel layer envelops the first crystal gel layer, the shimmering powder layer and the screen printing color layer, and is bonded to the soft layer and the pressure-sensitive adhesive layer.

### Claim 4 (depends on 1)

The gel nail sticker of claim 1, wherein at least one screen printing color layer is printed on the soft layer by screen printing, and the shimmering powder layer is printed on a top of the screen printing color layer by screen printing, and the first crystal gel layer covers on the shimmering powder layer.

### Claim 5

A manufacturing process for a gel nail sticker, comprising,
a. screen printing of a pressure-sensitive adhesive layer: a PET release film or release paper is selected as a base film layer having a thickness of 0.05-0.1 mm; one pressure-sensitive adhesive layer is printed on a top of the base film layer by screen printing, and dried for 20-50 minutes at room temperature of 25-35° C.;
b. screen printing of the soft layer: the soft layer is a mixture of isophorone and Ethylene glycol monobutyl ether, with a weight ratio of 40:60; the soft layer is printed on the pressure-sensitive adhesive layer by screen printing to isolate the pressure-sensitive adhesive layer from ink, and then the soft layer is dried for 80-120 minutes at room temperature of 25-35° C.;
c. screen printing of the screen printing color layer: the color layer is an ink layer;
according to the requirement of pattern, if the pattern is in one color, only one layer of ink layer is necessary to be printed, and if the pattern is in two colors, two layers are necessary to be printed, and so forth, by screen overprinting; in order to ensure saturation of the ink, every color is printed twice by screen printing, and instantly dried at room temperature of 25-35° C.;
d. screen printing of the shimmering powder layer: the shimmering powder layer is a layer of various models of glitter powder, flashing powder, laser powder, camouflage powder, iridescence pigment and pearl powder, or a layer of tinsel or electrochemical aluminium layer, and according to the purpose of design, the shimmering powder layer can be printed under or above the ink layer twice by screen printing, and dried for 20-50 minutes at room temperature of 25-35° C., to increase decoration of products;
e. screen printing of the crystal gel layer: a first crystal gel layer and a second crystal gel layer are layers of epoxide resin glue; at room temperature of 25-35° C., epoxide resin glue is printed once by screen printing, and after waiting for 10-15 minutes, the first crystal gel layer is formed, and then epoxide resin glue is printed by screen printing for a second time, and wait for 160-200 minutes to allow the epoxide resin glue to flow naturally to form the second crystal gel layer which is transparent and arc-shaped, and higher in the middle but lower on both sides.
