摘要：
The present invention provides a three-dimensional decorative piece made of a thermoplastic synthetic resin by which a design such as that of a gold lace thread can be expressed, and a method for producing the same. A three-dimensional decorative piece (10) made of a thermoplastic synthetic resin according to the present invention is a three-dimensional decorative piece (10) made of a thermoplastic synthetic resin that is produced by subjecting, to high-frequency dielectric heating, a decorative piece material (20) that includes an upper layer (30) that includes a thermoplastic synthetic resin film (31) having a vapor-deposited metal layer (32), an intermediate layer (60) that includes a thermoplastic synthetic resin sheet, and a lower layer (62) that includes a thermal bonding film, the decorative piece including: a first printing layer (40) printed using a transparent color ink, a matte ink, or a glossy ink, as an upper surface of the upper layer (30); and a second printing layer (50) in which a fine line (51) is printed using a transparent UV ink, on an upper surface of the first printing layer (40). It is desirable that the fine line (51) of the second printing layer (50) has a width of 0.1 mm to 0.25 mm.
技术问题语段：
The patent text discusses methods for producing three-dimensional decorative pieces made of thermoplastic synthetic resin using high-frequency dielectric heating. The technical problem addressed in this patent text is how to efficiently and accurately produce decorative pieces with complex shapes and designs using advanced technology.
技术功效语段：
The present invention relates to a three-dimensional decorative piece made of synthetic resin that has a fine line printing on its surface using a transparent UV ink. This printing can create a design that looks like gold lace embroidery, adding a three-dimensional appearance and a sense of luxuriousness to the decorative piece. The thickness of the printed fine line can also create a metallic appearance. The method for producing this decorative piece is also provided.
权利要求：
1. A three-dimensional decorative piece (10) made of a thermoplastic synthetic resin that is produced by subjecting, to high-frequency dielectric heating, a decorative piece material (20) that includes an upper layer (30) constituted by a thermoplastic synthetic resin film (31) having a vapor-deposited metal layer (32) and is provided with a three-dimensional design, an intermediate layer (60) constituted by a thermoplastic synthetic resin sheet, and a lower layer (62) constituted by a thermal bonding film the decorative piece comprising: a first printing layer (40) printed using a transparent color ink, a matte ink or a glossy ink, as an upper surface of the upper layer; and a second printing layer (50) in which a fine line (51) is printed using a transparent UV ink, on an upper surface of the first printing layer (40).
2. The three-dimensional decorative piece (10) made of a thermoplastic synthetic resin according to claim 1, wherein the fine line (51) of the second printing layer has a width of 0.1 mm to 0.25 mm.
3. The three-dimensional decorative piece (10) made of a thermoplastic synthetic resin according to claim 1 or 2, wherein the upper layer (30) has a protruding portion (22) formed through shaping, and the fine line (51) of the second printing layer (50) is printed to intersect an edge portion of the protruding portion (22).
4. The three-dimensional decorative piece (10) made of a thermoplastic synthetic resin according to any one of claims 1 to 3, wherein the upper layer (30) includes a migration prevention film (34) layer
5. A method for producing a three-dimensional decorative piece (10) made of a thermoplastic synthetic resin by subjecting, to high-frequency dielectric heating, a decorative piece material (20) that includes an upper layer (30) that is constituted by a thermoplastic synthetic resin film (31) having a vapor-deposited metal layer (32), has an outline, and is provided with a three-dimensional design, an intermediate layer (60) constituted by a thermoplastic synthetic resin sheet, and a lower layer (62) constituted by a thermal bonding film wherein the upper layer (30) is formed through a step of forming a first printing layer (40) in the upper layer (30) by screen printing a transparent color ink, a matte ink, or a glossy ink onto an upper surface of the thermoplastic synthetic resin film (31), a step of forming a second printing layer (50) in the upper layer (30) by screen printing a fine line (51) using a transparent UV ink onto an upper surface of the first printing layer (40), a step of curing the second printing layer (50) by irradiating the second printing layer (50) with ultraviolet rays, and a step of attaching an adhesive carrier film (70) to an upper surface of the second printing layer (50), the method comprising: a step of placing the decorative piece material (20) in which the lower layer (62), the intermediate layer (60), and the upper layer (30) are placed on each other in the stated order, on a table (101) serving as one electrode in high-frequency dielectric heating; a first high-frequency dielectric heating step of shaping the three-dimensional design in the upper layer (30) by pressing an engraved die (102) serving as another electrode in high-frequency dielectric heating against the upper layer (30) of the decorative piece material (20) and performing high-frequency dielectric heating, and fusion-cutting the decorative piece material (20) other than the carrier film (70) along the outline and fusing the upper layer (30) and the intermediate layer (60) to weld the resulting layer to the lower layer (62); an elimination step of eliminating an unnecessary portion that does not constitute the three-dimensional design of the fusion-cut decorative piece material (20) to obtain a decorative piece material (20); a second high-frequency dielectric heating step of welding a base material and the decorative piece material (20) by fitting the decorative piece material (20) into the engraved die (102) placed on the table (101) with an engraved surface facing upward such that the lower layer faces upward, placing the base material on the decorative piece material (20), pressing the base material against the decorative piece material (20) using a flat-plate die (104) from above the base material, and performing high-frequency dielectric heating; and an adjustment step of removing, from the engraved die (102), the decorative piece material (20) and the base material that are welded to each other, peeling off the carrier film (70), and cutting the base material to a desired shape to obtain a three-dimensional decorative piece (10) made of a thermoplastic resin.
