Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1, a first embodiment of a method for manufacturing an appearance article of the present invention comprises the following main steps: Step 101, forming an active layer containing an active metal on a first surface of a transparent sheet; Step 102, in a transparent sheet a second surface opposite to the first surface forms a decorative layer; in step 103, the transparent thin plate is shaped and solidified into a three-dimensional structure; and in step 104, a metal layer is formed on the surface of the active layer of the transparent thin plate by an electroless plating process, The metal layer is used as another decorative layer; and in step 105, a transparent plastic casing is formed on the second surface of the transparent sheet.

The implementation steps are described in detail below with other drawings.

Referring to FIG. 2 and FIG. 3, in step 101, an active layer 2 containing an active metal is formed on a first surface 11 of a transparent sheet 1. In detail, the transparent thin plate 1 has a first surface 11 and a second surface 12 opposite to the first surface 11, and in FIG. 3 of the embodiment, the first surface 11 is located on the lower side of the transparent thin plate 1, and The second surface 12 is then located on the upper side of the transparent sheet 1. Further, in this step, the active ink is printed on the first surface 11 to form the active layer 2, and the material of the active layer 2 comprises a catalytic property selected from the group consisting of palladium, rhodium, platinum, silver, or the like. A metal is used to catalyze metal deposition in the process of forming the metal layer 4 (see Figure 9). In this embodiment, the active layer 2 is composed of a non-conductive metal oxide.

It should be emphasized that the step of forming the active layer 2 by the above printing method can eliminate the conventional pre-roughening process by laser, since the activation layer 2 is conventionally formed by immersing the substrate in a metal ion-containing activity. The metal solution is adsorbed to the surface of the substrate for a predetermined period of time, and the step of roughening the surface of the substrate contributes to the adhesion of the metal ions. However, in the step of forming the active layer 2 by the printing method of the present embodiment, the constituent material of the active ink has a chemical medium which can slightly corrode the epoxy resin, and the chemical medium is N-methylpyrrolidone (N-methyl-2- Pyrrolidone, NMP), therefore, the first surface 11 of the transparent sheet 1 can be microetched by N-methylpyrrolidone, and the roughness of the first surface 11 is improved, and the solute in the active ink is made by chemical bonding. The first surface 11 is combined to increase the adhesion between the first surface 11 and the active ink, thus ensuring that the active ink adheres to the first surface 11 without pre-roughening the surface with a laser The steps can not only improve the production efficiency, but also use the general thermoplastic plastic material to make the transparent sheet 1, so the material price is lower, and the cost can be reduced.

Referring to FIGS. 4 and 5, step 102, a decorative layer 3 is formed on the second surface 12 of the transparent sheet 1. The function of the decorative layer 3 is to enhance the decorative effect of the appearance article 10 (see FIG. 11), so the decorative layer 3 can have a plurality of colors, patterns or shapes, and the decorative layer 3 can have a plurality of blocks or lines of different arrangement patterns. To present a diverse visual experience. In this embodiment, the material of the decorative layer 3 is ink, and may be attached to the second surface 12 by contact or non-contact, and the contact manner may be, for example, digital printing or coating technology, and the non-contact method is, for example, digital. Spraying technology.

Referring to Figures 6 and 7, step 103, the transparent sheet 1 is shaped and solidified into a three-dimensional structure.

Referring to FIG. 8 and FIG. 9, step 104, a metal layer 4 is formed on the surface of the active layer 2 of the transparent thin plate 1 by an electroless plating process, and the metal layer 4 is used as another decorative layer. The non-electroplating process described in this embodiment is, for example, an electroless plating process. Specifically, the step is to remove the transparent thin plate 1 from the plating solution after being placed in a plating solution for a predetermined time, and in the transparent thin plate 1 The surface of the active layer 2 forms a metal layer 4, and since the transparent thin plate 1 has become a three-dimensional structure, the metal layer 4 can naturally be formed into a three-dimensional metal decorative layer. In this embodiment, the material of the metal layer 4 is copper, but the material thereof may be nickel, and is not limited to the material disclosed in the embodiment.

Since the transparent thin plate 1 is made of a transparent material, the line of sight of the person can be penetrated from the second surface 12 to the first surface 11 so that when a user is viewed from above the second surface 12, not only the second surface 12 but also the second surface 12 can be seen. The decorative layer 3 can also see the metal layer 4 on the first surface 11, or the metal layer 4 on the first surface 11 and the decorative layer 3 on the second surface 12 are simultaneously seen by the first surface 11 from opposite directions, To increase the visual richness. In particular, the main function of the metal layer 4 in this embodiment is as a decorative layer, and the appearance thereof may be a shape, a figure or another pattern. However, in other embodiments, the metal layer 4 may also have a conductive line function. .

Referring to FIG. 10 and FIG. 11, step 105, a transparent plastic casing 5 is formed on the second surface 12 of the transparent sheet 1.
