Combined with a macroscopic three-dimensional image, under the influence of light, the signboard pattern dynamically appears three-dimensional, dazzling, and possesses a unique decorative personality that ordinary three-dimensional signs and markers cannot achieve. The metal signboard comprises:

[0031] A metal carrier includes a first surface and a second surface disposed opposite to it; the metal carrier can be formed by electroplating, and the material of the metal carrier can be nickel, copper, nickel alloy, etc., and the specific material used can be determined according to different needs;

[0032] Several three-dimensional images are provided, which are protruding from the first surface of the metal carrier. The three-dimensional images located on the first surface of the metal carrier can be formed by electroplating, so that the three-dimensional images and the metal carrier are an integral structure. The three-dimensional images protrude from the first surface of the metal carrier and have a distinct three-dimensional tactile feel.

[0033] The micro-nano graphics are located on the first surface of the metal carrier, wherein at least two adjacent micro-graphics are spaced apart, and the micro-nano graphics are located at the spaced intervals; the micro-nano graphics area exhibits a vibrant color effect. The micro-nano graphics include several micro-nano textures, which are raised and / or recessed on the first surface of the metal carrier. The micro-nano texture is one or a combination of two or more of the following: microlens, cylindrical mirror, CD pattern, Fresnel lens, brushed texture, and holographic structure. This allows the micro-nano texture to present a micro-nano texture effect, which can include dynamic light and shadow changes, naked-eye 3D effects, and iridescent colors. Combined with the tactile feel of the 3D graphics, this gives the metal sign a certain three-dimensional and dazzling effect. Of course, the surface of the 3D graphics can also have a micro-nano texture, so the 3D graphics themselves will also have a micro-nano graphic effect. The micro-nano graphics can also be formed by electroforming, and the micro-nano graphics and the metal carrier are also an integral structure. Thus, the 3D graphics, micro-nano graphics, and the metal carrier are a complete, integrated structure, formed as a single unit.

The reflective layer can be formed on the surface of the three-dimensional graphic and the micro-nano graphic by means of evaporation, sputtering, etc. In this way, the reflective layer can effectively display the effect of the three-dimensional graphic and the micro-nano graphic. There is a refractive index difference between the reflective layer and the materials of the micro-nano graphic and the three-dimensional graphic, and the reflective layer is formed of a material with a high refractive index. The refractive index difference between the reflective layer and the materials of the micro-nano graphic and the three-dimensional graphic is not less than 0.2.

[0035] As an improved technical solution of this utility model, it also includes a color-filling layer, which at least covers the area where the micro-nano graphics are located, such that the reflective layer is located between the micro-nano graphics and the color-filling layer. The color-filling layer material can be a colored material, which can improve the color saturation of the metal sign. Of course, the color-filling layer material has a certain transmittance, generally not less than 30%. Of course, the color-filling layer can have a higher transmittance, such as 50% or 70%, only in this way can the effect of the micro-nano graphics be externalized. Furthermore, the color-filling layer can be set locally, which can achieve the effect of local color modification, making the colors of different areas of the metal sign different.

[0036] As an improved technical solution of this utility model, the three-dimensional graphic includes a top and two sidewalls, which together form an open cavity, with the opening of the cavity facing the second surface of the metal carrier. The three-dimensional graphic is actually hollow inside, and the opening of the open cavity formed by the hollowed-out area is located on the second surface of the metal carrier. Of course, the second surface of the metal carrier corresponding to the micro / nano graphic can be planar or non-planar with undulations.

[0037] As an improved technical solution of this utility model, a filling layer is provided inside the cavity, and the filling layer fills the cavity; or, a filling layer is provided on the second surface of the metal carrier, and the filling layer fills the cavity. In order to ensure the support strength of the three-dimensional graphic, a filling layer can be provided inside the cavity. The filling layer can be resin, and the filling layer can fill the cavity. The second surface of the metal carrier, except for the cavity area, does not have a filling layer. Of course, the filling layer can cover the entire second surface of the metal carrier, and the cavity is still filled with the filling layer.

[0038] As an improved technical solution of this utility model, it further includes an adhesive layer, which is located on the second surface of the metal carrier and is used to bond the carrier to be bonded. When the filling layer only fills the cavity, a portion of the adhesive layer is in direct contact with the second surface of the metal carrier; when the filling layer covers the entire second surface of the metal carrier, the adhesive layer is formed directly on the surface of the filling layer.

[0039] This application also provides a method for preparing a three-dimensional metal sign, characterized by comprising the following steps:

When the filling layer 40 only fills the cavity, a portion of the adhesive layer 70 is in direct contact with the second surface of the metal carrier 10.
