     SUMMARY OF INVENTION 
     Technical Problem 
     Some decorative pieces produced through embroidery are provided with gold lace embroidery by embroidering a base material with a so-called gold lace thread obtained by winding a gold thread and a silver thread around a core thread. However, with conventional three-dimensional decorative pieces made of a thermoplastic resin produced through high-frequency dielectric heating, while uneven designs can be expressed, sufficient expression of a sense of luxuriousness, an aura of substance, elaborateness, a depth of color, a metallic appearance, and the like such as those of gold lace embroidery has not been possible. One of the reasons therefor is that there is a limitation on how fine a design can be formed in an engraved die used in high-frequency dielectric heating. Thus, when a gold lace design needs to be formed, embroidery has needed to be manually performed using a gold lace thread. Also, there are cases where a thermoplastic synthetic resin film and a base material sheet are separated from each other through washing, friction, and the like due to insufficient adhesive strength between the thermoplastic synthetic resin film and the base material sheet. 
     An object of the present invention is to provide 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. 
     Solution to Problem 
     A three-dimensional decorative piece made of a thermoplastic synthetic resin according to the present invention is a three-dimensional decorative piece made of a thermoplastic synthetic resin that is produced by subjecting, to high-frequency dielectric heating, a decorative piece material that includes an upper layer constituted by a thermoplastic synthetic resin film having a vapor-deposited metal layer, an intermediate layer constituted by a thermoplastic synthetic resin sheet, and a lower layer constituted by a thermal bonding film, 
     the decorative piece including: 
     a first printing layer 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 in which a fine line is printed using a transparent UV ink, on an upper surface of the first printing layer. 
     It is desirable that the fine line of the second printing layer has a width of 0.1 mm to 0.25 mm. 
     It is desirable that the upper layer has a protruding portion formed through shaping, and 
     the fine line of the second printing layer is printed to intersect an edge portion of the protruding portion. 
     The upper layer may be configured to include a migration prevention film layer. 
     Also, a method for producing a three-dimensional decorative piece made of a thermoplastic synthetic resin according to the present invention is a method for producing a three-dimensional decorative piece made of a thermoplastic synthetic resin by subjecting, to high-frequency dielectric heating, a decorative piece material that includes an upper layer that is constituted by a thermoplastic synthetic resin film having a vapor-deposited metal layer, has an outline, and is provided with a three-dimensional design, an intermediate layer constituted by a thermoplastic synthetic resin sheet, and a lower layer constituted by a thermal bonding film, 
     wherein the upper layer is formed through 
     a step of forming a first printing layer in the upper layer by screen printing a transparent color ink, a matte ink, or a glossy ink onto an upper surface of the thermoplastic synthetic resin film, 
     a step of forming a second printing layer in the upper layer by screen printing a fine line using a transparent UV ink onto an upper surface of the first printing layer, 
     a step of curing the second printing layer by irradiating the second printing layer with ultraviolet rays, and 
     a step of attaching an adhesive carrier film to an upper surface of the second printing layer, 
     the method including: 
     a step of placing the decorative piece material in which the lower layer, the intermediate layer, and the upper layer are placed on each other in the stated order, on a table 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 by pressing an engraved die serving as another electrode in high-frequency dielectric heating against the upper layer of the decorative piece material and performing high-frequency dielectric heating, and fusion-cutting the decorative piece material other than the carrier film along the outline and fusing the upper layer and the intermediate layer to weld the resulting layer to the lower layer, 
     an elimination step of eliminating an unnecessary portion that does not constitute the three-dimensional design of the fusion-cut decorative piece material to obtain a decorative piece material, 
     a second high-frequency dielectric heating step of welding a base material and the decorative piece material by fitting the decorative piece material into the engraved die placed on the table with an engraved surface facing upward such that the lower layer faces upward, placing the base material on the decorative piece material, pressing the base material against the decorative piece material using a flat-plate die from above the base material, and performing high-frequency dielectric heating, and 
     an adjustment step of removing, from the engraved die, the decorative piece material and the base material that are welded to each other, peeling off the carrier film, and cutting the base material to a desired shape to obtain a three-dimensional decorative piece made of a thermoplastic resin. 
     Effects of the Invention 
     According to the three-dimensional decorative piece made of a thermoplastic synthetic resin and the method for producing the same according to the present invention, the decorative piece material has, as a surface of the upper layer, a second printing layer in which a fine line is printed using a transparent UV ink. This fine line of the second printing layer can express a design such as that of gold lace embroidery on a protruding design formed by shaping the upper layer, and can express, on a three-dimensional decorative piece made of a thermoplastic synthetic resin, a three-dimensional appearance, a texture, a sense of luxuriousness, elaborateness, a metallic appearance, and the like such as those of gold lace embroidery, by increasing the thickness of a printed fine line.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, a three-dimensional decorative piece  10  made of a thermoplastic synthetic resin of the present invention and a method for producing the three-dimensional decorative piece  10  will be described with reference to the drawings. Note that, in the drawings, the thicknesses of a layer is shown exaggerated to facilitate the explanation as needed. Also, the shapes, the designs, the thicknesses, and the like of the decorative piece  10 , a decorative piece material  20 , a base material sheet  80 , and the like are given by way of example only, and can be changed as appropriate. 
       FIG.  1    is a plan view of the decorative piece  10  according to an embodiment of the present invention,  FIG.  2    is a cross-sectional view of the decorative piece  10  shown in  FIG.  1    cut along line A-A and viewed in the arrow direction, and  FIG.  3    is an enlarged cross-sectional view showing an overview of one protruding portion  22  of a decorative piece material  20  that has been shaped. Note that  FIG.  3    shows the decorative piece material  20  as one layer excluding a fine line  51  to facilitate the explanation. As shown in  FIGS.  1  and  2   , the decorative piece  10  is formed by welding the shaped decorative piece material  20  onto the base material sheet  80 . The decorative piece material  20  is provided with desired recesses and protrusions, and a desired design, and a contour portion of the design is fusion-cut. In an embodiment shown in  FIGS.  1  to  3   , designs formed by the decorative piece material  20  includes a bird  90  perched on a ring, plant leaves  91 , and a central lily emblem  92 . As shown in  FIG.  3   , in the bird  90  and the leaves  91  out of these designs, minute designs  24  such as those of lace embroidery are expressed on the shaped protruding portion  22 . As shown in  FIG.  3   , these minute designs  24  such as those of lace embroidery are realized by printing minute fine lines  51  (see  FIGS.  4  and  7   ) onto the protruding portions  22  of the designs using a transparent UV ink. Note that a minute design such as that of lace embroidery can be optionally applied to any design, and naturally, it is also possible to apply lace embroidery designs to all of the designs. 
       FIG.  4    is a plan view of the decorative piece material  20 , and shows a diagram thereof before the high-frequency dielectric heating step is performed. Also,  FIG.  5    is a cross-sectional view of the decorative piece  20  shown in  FIG.  4    cut along line B-B and viewed in the arrow direction. As shown in  FIG.  5   , the decorative piece material  20  includes an upper layer  30 , an intermediate layer  60 , and a lower layer  62 , and the upper surface of the upper layer  30  is provided with a first printing layer  40  (a design  41 ) and a second printing layer  50  (a design  52 ), and in this embodiment, the bird, the leaves, and the lily emblem are lastly formed by designs of these printing layers  40  and  50 , and through shaping. 
     In the decorative piece material  20 , the upper layer  30 , the intermediate layer  60 , and the lower layer  62  are integrated with each other through a first high-frequency dielectric heating step. Also, a carrier film  70  for holding a design separated in a production process at a predetermined position, and a polypropylene film  72  for protecting the carrier film  70  may be attached to the upper surface of the decorative piece material  20 . Hereinafter, configurations and typical materials of the layers will be described as examples. 
     As shown in  FIG.  5   , the upper layer  30  is a laminated film including a thermoplastic synthetic resin film  31  that can be molded through high-frequency dielectric heating, a vapor-deposited metal layer  32 , and the like. The thermoplastic synthetic resin film  31  may be made of a soft thermoplastic synthetic resin such as polyurethane, for example. In the example shown in the drawings, the vapor-deposited metal layer  32  is formed on the thermoplastic synthetic resin film  31  that is located on the upper surface side, through metal vapor deposition. Also, a migration prevention film  34  is provided on a lower surface of the vapor-deposited metal layer  32  via an adhesive layer  33 , and furthermore a thermoplastic synthetic resin film  36  is provided thereunder via an adhesive layer  35 , thus forming a six-layer structure. 
     Examples of the migration prevention film  34  may include an ethylene-vinyl alcohol copolymer (EVOH) film and a polyamide resin-based film such as polyamide MXD6, and the migration prevention film  34  prevents a dye of the base material sheet  80  and a dye of a garment or the like to which the decorative piece  10  is attached from migrating to a front surface side of the decorative piece material  20 . 
     A soft sheet of a thermoplastic synthetic resin or a foamed resin sheet can be used as the intermediate layer  60 , and the intermediate layer  60  may be made of a thermoplastic synthetic resin such as soft polyvinyl chloride (PVC), for example. 
     A thermal bonding film can be used as the lower layer  62 . Examples of the thermal bonding film include polyamide-based, polyurethane-based, polyester-based, and ethylene vinyl acetate copolymer (EVA)-based films. Note that the material of the lower layer  62  can be selected as appropriate depending on the type of base material sheet  80 , which will be described later. 
     Specifically, as shown in  FIG.  6   , the first printing layer  40  printed in a desired design and desired color using a transparent color ink, a matte ink, a glossy ink, or the like is formed as the upper surface of the upper layer  30  having the above-described configuration, specifically, on the upper surface of the thermoplastic synthetic resin film  31 . Note that, although the first printing layer  40  is shown as one layer having a thickness in  FIG.  5   , as shown in  FIG.  6   , only the portion where a design  41  (see  FIG.  4   ) printed on the upper surface of the upper layer  30  is present is the first printing layer  40 . 
     In  FIG.  5   , a design to be shaped through a later-described first high-frequency dielectric heating step, that is, the design  41 , is printed onto the first printing layer  40  such that positions corresponding to those of the bird, the leaves, and the lily emblem are colored. Out of these positions, the positions corresponding to the bird and the leaves are colored a golden color, the position corresponding to the lily emblem is colored a silver color, and portions corresponding to the leaves are colored by partially changing the depth of a color. Note that, if the vapor-deposited metal layer  32  has a silver color, a golden color can be developed by applying a yellow color or an orange color. Also, the color of the vapor-deposited metal layer  32  may be directly utilized as the silver color of the lily emblem. The first printing layer  40  can be formed through screen printing, for example. Although SG410 manufactured by Seiko advance Ltd. may be employed as a matte ink or a glossy ink to be used, for example, there is no limitation thereon. 
     Also, the second printing layer  50  subjected to printing using a transparent UV ink is formed on the upper surface of the first printing layer  40 . The second printing layer  50  can be formed by printing, onto a desired design portion, overlapping the design  41  of the first printing layer  40 , a transparent UV ink to make a design  52  realized by fine lines  51 . Note that, although the second printing layer  50  is shown as one layer having a thickness in  FIG.  5   , only the portion present on the design  41  of the first printing layer  40  indicates the second printing layer  50 .  FIG.  7    only shows the design  52  constituted by the fine lines  51  printed as the second printing layer  50 , and in this embodiment, in the design  41  of the first printing layer  40  shown in  FIG.  6   , designs constituted by the fine lines  51  are added to portions corresponding to the bird  90  and the leaves  91  (see  FIG.  1   ). The second printing layer  50  can be implemented through screen printing, for example. Also, the fine lines  51  may be printed to have a line width of 0.1 mm to 0.25 mm, and have a line thickness of 5 μm to 15 μm. This second printing layer  50  can express, in the protruding portions  22  formed through shaping, a sense of luxuriousness, an aura of substance, elaborateness, a depth of color, and a metallic appearance such as those of lace embroidery, as well as minute recesses and protrusions, and the like. 
     Although a transparent UV ink used for the second printing layer  50  is an ultraviolet-curable ink and an example thereof is UV5410 manufactured by Seiko advance Ltd., for example, there is no limitation thereon. 
     As shown in  FIG.  8    that shows an enlarged view of a circled portion C shown in  FIG.  4   , a fibrous appearance of lace embroidery can be satisfactorily expressed by printing the fine lines  51  to intersect portions (indicated by a dash-dot line in  FIG.  8   ) that will serve as protruding portions  22  as a result of being shaped through a later-described first high-frequency dielectric heating step. 
     In the second printing layer  50 , the printed fine lines  51  are cured by irradiating the surface of the second printing layer  50  with ultraviolet rays after printing is performed using a transparent UV ink. 
     As shown in  FIG.  5   , a carrier film  70  and a polypropylene film  72  can be attached to the upper surface of the second printing layer  50  as needed. An adhesive material can be used as the carrier film  70 , and when the decorative piece material  20  is fusion-cut, the carrier film  70  functions to hold the separated design at a predetermined position. Also, the polypropylene film  72  is used in order to reinforce the carrier film  70  and is disposed in tight contact with the carrier film  70 . The polypropylene film may have a thickness of 30 μm to 80 μm. 
     Although an example of the carrier film  70  is a sheet obtained by applying an acrylic adhesive to a special polypropylene film, such as A-2430 or L-3310 HITALEX manufactured by Hitachi Chemical Company, Ltd., there is no limitation thereon. Note that, if there is a risk that an adhesive of the carrier film  70  will remain on the second printing layer  50  and the brightness of a metal tone portion of the second printing layer  50  will decrease, elimination of the carrier film  70  can prevent a decrease in the brightness thereof. In this case, although the holding force is slightly decreased, the polypropylene film  72  can function as the carrier film  70 . 
     It is sufficient to attach the carrier film  70  to the upper surface of the second printing layer  50  using a hand roller, and to place the polypropylene film  72  thereon in tight contact therewith. Note that these films  70  and  72  are peeled off in a final process, and will not remain on the decorative piece  10 . 
     The upper layer  30  (that includes the first printing layer  40  and the second printing layer  50 ), the intermediate layer  60 , and the lower layer  62  that have the above-described configuration are placed on each other to constitute the decorative piece material  20 , a piece of release paper is disposed on the lower surface of the lower layer  62 , the three-dimensional designs are shaped on the upper layer  30  and the designs are cut in the first high-frequency dielectric heating step, and the upper layer  30 , the intermediate layer  60 , and the lower layer  62  are integrated with each other through fusion. 
     The first high-frequency dielectric heating step can be performed using a molding die (forming die)  100  for high-frequency dielectric heating shown in  FIGS.  9  to  11   . The molding die  100  includes a table  101  serving as one electrode and an engraved die  102  serving as another electrode. The table  101  is formed flat. The engraved die  102  has an engraved surface that is engraved to any shape such as a mountain shape, a trapezoidal shape, an arc shape, and other shapes, for example, in order to shape a three-dimensional design on the upper layer  30 . In  FIG.  10   , the three-dimensional design of the engraved die  102  is constituted by recesses and protrusions that form the bird  90 , the leaves  91 , and the lily emblem  92 . Referring to  FIG.  10   , it can be understood that the three-dimensional design formed in the engraved die  102  does not have recesses or protrusions in portions that correspond to the fine lines  51 , and is smooth. Also, the engraved die  102  is provided with fusion-cutting blades  103  having sharp cutting edges extending along outlines of designs to be molded, at positions corresponding to outer edges of the designs. Note that the configuration of the molding die  100  is not limited to the above-described configuration, and a known molding die used in high-frequency dielectric heating can also be adopted, for example. 
     Therefore, the decorative piece material  20 , that is, the lower layer  62  on which the release paper is disposed, the intermediate layer  60 , and the upper layer  30  to which the carrier film  70  and the polypropylene film  72  are attached are placed on each other in the stated order on the table  101 , and as shown in  FIGS.  9  and  10   , the engraved die  102  is moved downward with the engraved surface facing downward. Then, insulators of the upper layer  30 , the intermediate layer  60 , and the lower layer  62  generate heat and fuse to each other as a result of performing high-frequency dielectric heating in a known manner, the intermediate layer  60  expands and is shaped following the engraved surface, and the upper layer  30 , the intermediate layer  60 , and the lower layer  62  are welded to each other. Also, the upper layer  30 , the intermediate layer  60 , and the lower layer  62  are fusion-cut by the fusion-cutting blades  103  of the engraved die  102  at the outer edges of the designs simultaneously. Note that the release paper, the carrier film  70 , and the polypropylene film  72  are not fusion-cut by the fusion-cutting blades  103 . 
       FIG.  12 ( a )  shows one engraved surface of the engraved die  102 ,  FIG.  12 ( b )  shows the decorative piece material  20  to be shaped, and  FIG.  12 ( c )  shows the shaped decorative piece material  20 . These diagrams all show an enlarged partial cross-sectional view of one protruding portion  22  of the decorative piece material  20 . Note that, with the decorative piece material  20 , the release paper, the carrier film  70 , and the polypropylene film  72  are not shown, and layers other than that of the fine lines  51  that constitute the second printing layer  50  are not shown as appropriate. It can be understood that, although, as shown in  FIG.  12 ( c ) , the fine lines  51  having a film thickness remain on the protruding portion  22  as the design  24  by pressing a recessed and smooth engraved surface of the engraved die  102  shown in  FIG.  12 ( a )  against the decorative piece material  20  shown in  FIG.  12 ( b )  in the arrow direction, the fine lines  51  are pressed by the engraved die  102  through molding and sunk into the decorative piece material  20 , and the protruding portion  22  does not have recesses or protrusions formed by the fine lines  51 , and thus the design  24  is flat along the engraved surface. 
     When high-frequency dielectric heating is complete, the engraved die  102  is moved upward, and the decorative piece material  20  is removed from the molding die  100 . Although the removed decorative piece material  20  is split at the outer edges of the designs, the decorative piece material  20  is adhered to the carrier film  70  due to the adhesive force of the carrier film  70 . Then, the release paper is peeled off, and as shown in  FIGS.  13  and  14   , unnecessary portions (indicated by reference numeral  26  in  FIG.  13   ) of the design that has been fusion-cut from the decorative piece material  20  are peeled off from the carrier film  70  while necessary portions  90 ,  91 , and  92  of the fusion-cut design are kept attached to the carrier film  70 . 
     Next, a second high-frequency dielectric heating step for integrating the obtained decorative piece material  20  with the base material sheet  80  is performed. Examples of the base material sheet  80  may include a woven fabric, a knitted fabric, a nonwoven fabric, felt, a synthetic resin sheet, and a synthetic leather. 
     In the second high-frequency dielectric heating step, as shown in  FIG.  15   , the molding die  100  is configured such that the engraved die  102  used previously is placed on the table  101  as one electrode, and a flat die  104  serving as another electrode is disposed above the engraved die  102  to be capable of being brought closer thereto. The engraved die  102  is placed with the engraved surface thereof facing upward, the decorative piece material  20  from which unnecessary portions have been eliminated is fitted into the engraved die  102  such that the polypropylene film  72  faces downward and the thermal bonding film that serves as the lower layer  62  faces upward, and the base material sheet  80  is placed on the upper surface of the decorative piece material  20  with the surface of the base material sheet  80  facing downward. 
     Then, as shown in  FIG.  15   , the flat die  104  is moved downward toward the engraved die  102 , and pressing is performed by the flat die  104  while performing high-frequency dielectric heating in a known manner, and thus the thermal bonding film serving as the lower layer  62  of the decorative piece material  20  is fused and the decorative piece material  20  is firmly welded to the base material sheet  80 . 
     When the second high-frequency dielectric heating step is complete, the flat die  104  is moved upward, the decorative piece material  20  and the base material sheet  80  that are integrated with each other are removed from the engraved die  102 , the polypropylene film  72  and the carrier film  70  are peeled off from the surface thereof, and the three-dimensional decorative piece  10  made of a thermoplastic synthetic resin can be obtained by cutting the base material sheet  80  to any outer shape as shown in  FIG.  1   . A known method such as Thomson punching or laser cutting may be used as a method for cutting the base material sheet  80 . 
     As shown in  FIGS.  1  and  3   , with the obtained decorative piece  10 , in the protruding portions  22  shaped through the first high-frequency dielectric heating step, fibrous designs are expressed in color by the fine lines  51 , the fine lines  51  constitute a design  24  that provides a visual impression such as those of recesses (grooves) due to differences in colors, can embody an architectural design having a three-dimensional appearance such as that of gold lace embroidery, and have a sense of luxuriousness, an aura of substance, elaborateness, a depth of color, a metallic appearance, and the like. 
     Also, in the second high-frequency dielectric heating step, the decorative piece material  20  and the base material sheet  80  are bonded as firmly as possible to each other through fusion of the thermal bonding film of the lower layer  62 , as compared with a conventional configuration, and thus it is also possible to prevent the decorative piece material  20  and the base material sheet  80  from separating from each other through washing, friction, and the like. 
     The foregoing description is given merely to describe the present invention, and therefore should not be construed as limiting the invention recited in the appended claims or narrowing the scope of the present invention. Also, the constituent elements of the present invention are not limited to those described in the embodiments above, and it is of course possible to make various modifications within the technical scope defined in the appended
