Patterns obtained by direct ink printing or spraying are easily removed during use or by scratching to affect the original appearance of the product. The fox process directly prints the desired pattern and background color on the hidden film by using the ink, and the film printed with the desired pattern is formed by injection molding or hot press forming, and then injection molded in the mold. Since the ink printed pattern layer is located between the injection molding plastic layer and the film, the pattern is not easily worn or scratched during use. However, when the film is heated and softened by the above process, the deformation of the pattern is easily displaced and the ink flows. The shadow edge is created, thereby forming a transition zone between the background and the pattern, thus seriously affecting the aesthetics and quality of the product. Moreover, the pattern color and the background color are not easy to form a plurality of combinations, and the pattern is relatively simple.

[Embodiment] The housing 100 of the preferred embodiment of the present invention, as shown in Fig. 1, comprises a base 10, a paint layer 12, an electric ore layer 14, and an electrophoretic coating layer 16. The paint layer 12 and the plating layer 14 are respectively formed on the surface of the substrate 1 opposite to each other, and the electrophoretic coating film 16 is formed on the surface of the plating layer 14. The substrate 10 is made of a transparent plastic material and includes a first surface 102 and a second surface 1〇4 opposite the first surface. At least one surface of the first surface 102 and the second surface 104 of the substrate is coated with a photosensitizer comprising at least one organometallic compound and a photoactivatable component, so that when the surface of the substrate 10 is irradiated with laser light, A metal layer is deposited in the irradiated region or a metal crystal nucleus required to form a conductive layer is formed. The photosensitive agent of this embodiment is applied to the second surface 104. The plating layer 14 is formed on the surface of the substrate 10 coated with the photosensitizer. The present embodiment is formed on the second surface 104, which covers a portion of the second surface 1〇4 to form a predetermined pattern. The electrophoretic coating crucible 16 is formed on the surface of the electroplated layer 14. The electrophoretic coating 臈16 can be selected according to the needs of different colors. The paint layer 12 is formed on the other opposite surface of the substrate 1 and this embodiment is a first surface 102 which can be selected to have a different color as desired.

In a preferred embodiment of the present invention, a method of fabricating a housing 100 includes the steps of: a first step of providing a transparent plastic substrate 10. The base 10 includes a first surface 102 and a second surface ι 4 opposite the first surface. At least one surface of the first surface 102 and the second surface 104 is coated with a photosensitizer containing a photoactivatable component, so that when the surface of the substrate 10 is exposed to a recording, a metal layer can be deposited or formed into a conductive region in the irradiated region. The desired metal nucleus. The photosensitizer of this embodiment is applied to the second surface 104. The activating substrate 10, that is, a laser-irradiated substrate 1 is coated with a photosensitive agent, and a predetermined area of the surface is used as the second surface 1 〇 4 to deposit a metal layer or form a conductive layer in a predetermined region.

The substrate 10 subjected to the above electrowinning treatment is subjected to an electrophoretic coating treatment to deposit an electrophoretic coating film 16 on the plating layer 14. In this step, since the electrophoretic coating system puts the object to be coated and the corresponding electrode into the water-soluble paint, and after the power source is connected, the physicochemical action generated by the electric field is used to deposit the resin in the paint and the pigment of 201018591 in the coating. The conductive surface of the object forms a water-insoluble paint film, and the surface of the substrate of the present invention is electrically conductive only, so that the electrophoretic coating film 16 is only covered on the plating layer 14.
