Description

3D texture transfer film

A 3D texture transfer film that enables the transferred texture to be more pronounced or deeper and reduces film processing and materials.

In recent years, 3C products have been widely used in people's daily lives, such as mobile phones, notebook computers, tablet computers or handheld electronic products. Although such electronic products have made people's lives quite convenient, the shells of such electronic products have been made. The system is relatively monotonous, so all major manufacturers are thinking about how to improve the style of the outer casing.

A common improvement is in the envelope or film mode, which coats or attaches a film or grain to the outer casing to improve the appearance of the outer casing.

Referring to FIG. 1 , the existing three-dimensional (3 dimension) 3D texture film system is a transfer film having a carrier 10 , a first hardened layer 11 , a release layer 12 , and a second hardened layer . 13. A printed layer 14, a metal layer 15 and an adhesive layer 16, the layers being stacked in sequence.

However, when the film body is actually produced, it is coated with a first colloid on one side of the carrier 10, and the colloid is pressed with a textured roller or a mold so that one side of the colloid has a first texture 110.

An ultraviolet or a high temperature cures the colloid to form a first hardened layer 11 having a first texture 110, the release layer 12 is disposed on the first texture 110, and a coating is applied to one side of the release layer 12. The second colloid, the first texture 110 is transferred to the second colloid through the release layer 12, and the second colloid has a second texture 130, and the second adhesive system is further cured to form the second hardened layer 13, and then printed. The layer 14, the metal layer 15 and the subsequent layer 16 are sequentially stacked to form the above-mentioned film body.

The film system is attached or coated on the outer layer through the adhesive layer 16 and passes through the release layer 12 to remove the carrier 10 and the first hardened layer 11, so that the outer shell has a striatum, Color or text.

However, one of the most criticized ones is that the release layer 12 between the first texture 110 and the second ridge 130 generally causes the first texture 110 to be ineffectively transferred to the second gel, while the texture of the second texture 130 is made. Too light or unable to render, and can not achieve the effect that the operator wants.

In addition, the use of the multilayer material of the first hardened layer 11, the release layer 12 and the second hardened layer 13 invisibly increases the cost and waste of materials, so how to improve the existing film body becomes a space for the industry to work hard.

In view of the above disadvantages, the object of the present invention is to provide a 3D texture transfer film and a method for manufacturing the same, which can reduce the material of the film to reduce the cost and directly transfer the first texture to the second texture, so that The second texture is more pronounced or deeper, and meets the needs of the industry.

In order to achieve the above object, the technical means of the present invention is to provide a 3D texture transfer film having a carrier layer having a first texture on one side and a glue layer on the carrier layer having a first texture. On the other side, the glue layer has a second texture corresponding to the position of the first texture; and an adhesive layer is attached to the other side of the glue layer.

In summary, the transfer film of the present invention and the method for producing the same, the first texture is directly formed on the carrier layer instead of a hardened layer, and the first texture and the second texture have no release layer, and the texture of the second texture can More obvious or profound, to meet the needs of the industry.

Since there is no need for another hardened layer and a release layer, the material of the present invention is reduced in the production of a film, so that cost can be saved.
