Referring to FIG. 1 , FIG. 2 , FIG. 5 and FIG. 6 , the step flow S200 of the three-dimensional glass structure 200 of the second embodiment of the present invention and the step flow S100 of the three-dimensional glass structure 100 of the first embodiment of the present invention are described. Substantially similar (ie, step S110 is similar to step S210), and step S210 has been described in the above paragraph, and will not be described in detail herein. The above two differences are that the decorative layer 204 of the second embodiment has a multilayer structure, and the decorative layer 104 of the first embodiment has a single layer structure.

In detail, a resin material layer (not shown) may be formed on the base layer 204a by a roll coating method, a spray coating method, a printing method, or a coating method. Next, the resin material layer is irradiated with ultraviolet light or heated to cure or harden to form the hard coat layer 204b. In an embodiment, the material of the resin material layer may be, for example, an ultraviolet curable resin or a thermosetting resin. For example, the material of the resin material layer may be, for example, an acrylic resin, a polyurethane (PU), or a ring. A resin material of an epoxy resin or a combination thereof.

The pattern layer 204c can increase the variety of patterns and colors of the three-dimensional glass structure 200 to enrich the visual effect of the user or the viewer. In an embodiment, the material of the pattern layer 204c may be, for example, a polyurethane or polyacrylate mixed with an inorganic material or the like. In some embodiments, when the first surface 205a of the hard coat layer 204b is a concave-convex surface, the formed pattern layer 204c may completely cover the uneven surface 205a of the hard coat layer 204b to enhance the flatness of the first surface 205a. degree. Therefore, the pattern layer 204c can not only enrich the visual effect of the user or the viewer, but also increase the adhesion of the subsequently formed first adhesive layer 204d.

However, the present invention is not limited thereto. In other embodiments, step S220 may be performed first, and then step S210 is performed.

Next, in step S230, a transfer molding process is performed such that the decorative layer 204 is adhered to the back surface 102b of the three-dimensional glass layer 102 through the first adhesive layer 204d. In detail, the transfer molding process is, for example, a heating step of the decorative layer 204 to soften the decorative layer 204. In an embodiment, the temperature of the heating step may be between 80 ° C and 150 ° C; the heating step may be between 30 seconds and 180 seconds. Next, the first adhesive layer 204d of the decorative layer 204 is brought into contact with the back surface 102b of the three-dimensional glass layer 102, and a pressurizing step is performed. The decorative layer 204 is transferred to the back surface 102b of the three-dimensional glass layer 102 through the first adhesive layer 204d. Finally, the remaining decorative layers can be selectively removed by knife cutting, laser cutting or water jet cutting. In short, in this embodiment, the decorative layer 204 can be closely adhered to the back surface 102b of the three-dimensional glass layer 102 by a transfer molding process. In one embodiment, the transfer molding process can be considered an exterior molding technique.

It is worth mentioning that the decorative layer 204 attached to the back surface 102b of the three-dimensional glass layer 102 not only has a decorative effect, but also has an explosion-proof function. The term "explosion-proof" means that when the three-dimensional glass structure 200 of the present embodiment is subjected to a force such as dropping, external force impact or external force pressing, it is not easily damaged or broken. Therefore, the three-dimensional glass structure 200 of the present embodiment or the decorative molded article including the three-dimensional glass structure 200 can have better protection than the conventional three-dimensional glass structure.
