Such an illumination type panel is generally a resin molded product in which a decorative film is laminated and integrated on the surface, and the illumination part has translucency, and illumination from the back side of the illumination type panel. As a result, the illumination unit emits light (for example, Patent Documents 1 and 2). Moreover, the design surface of such an illumination type panel is often provided with a metallic decoration part in which a metallic decoration having a gloss is provided at a place different from the illumination part.
  7 and 8 show a conventional illumination type panel 1a having a metallic decoration part. Such an illumination type panel 1a is disposed in a shift lever operation portion of an automobile, and includes a panel main body 2a having a lever opening 7a through which the shift lever L passes, and an outer periphery of the panel main body 2a.

  By the way, the said conventional illumination type panel 1a is manufactured by laminating | stacking and integrating the decorative film 11a on the surface of the resin base material 9a by film insert injection molding. However, as shown in FIG. 8, the metallic decoration 6a is not formed in the component 24 in which the decorative film 10a is laminated and integrated, but is constituted by a separate component 25 plated. For this reason, in the conventional illumination type panel 1a provided with the metallic decoration part 6a, at least two parts of the component 24 which laminated | stacked the decorative film 10a and the plating component 25 which comprises the metallic decoration part 6a are required. The mold cost and assembly cost were high. In addition, the gap between the two parts 24 and 25 appearing on the design surface 4a has a problem that the design property is lowered.
  In response to these problems, it is proposed that the decorative film is printed with glitter ink to replace the metallic decoration by plating and the entire design surface is made up of a single part without any gaps. The However, since the glitter ink contains only about 20% of the metal powder, it is not possible to obtain a sufficient metal gloss by printing with the glitter ink.
  It is also proposed to replace the metallic decorative part by plating by stamping the decorative film. However, although the metal foil pressed is 100% metal, it is whitened by the heat of the molten resin at the time of film insert injection molding. Thus, sufficient metal gloss cannot be obtained even by such a method.
  The present invention has been made in view of the present situation, and an object of the present invention is to provide an illuminating panel that includes a glossy metallic decoration portion and is easy to manufacture and a manufacturing method thereof.
The present invention is an illuminating panel that includes an illumination unit that emits light by illumination from the back surface side and a metallic decoration part having a metallic luster on a design surface, the design surface including the illumination part and the metallic decoration part However, the decorative film is formed of a single decorative film laminated and integrated on the surface of the resin base material, and the decorative film has a metallic luster and is a thin-film metal layer capable of partially transmitting light. A thin-film metal layer capable of transmitting light, a heat-insulating resin layer having a thickness of 100 μm or more provided on the back side of the thin-film metal layer, and a transparent layer provided on the surface side of the thin-film metal layer It is equipped with a surface resin layer and a surface printed layer printed on the surface side of the surface resin layer, and the metallic decoration part is lined with resin or ink that does not transmit light and transmits illumination from the back side. It is configured so as not to, the surface printing layer is metallic Portion forming the decorative part has or missing a transparent, portions not forming the metallic decorative portion is not clear, furthermore, the portion forming the illuminating unit has a light-transmitting property, metallic The illumination panel is characterized in that the gloss of the decorative portion is formed by a thin film metal layer, and the gloss of the thin film metal layer is not visually recognized in the illumination portion.
  Here, in the present invention, “transparent” refers to the property of transmitting light and allowing the other side to be seen through the substance, and includes those having a color. “Translucent” refers to the property of transmitting light and not clearly recognizing the shape of the other side through the substance, and includes those having a color. “Opaque” refers to a property that is not “transparent”. Further, “transmitting light” is a property including “transparent” and “translucent”.
  In the present invention, as shown in FIG. 1, the thin metal layer 11 that forms the luster of the metallic decorative portion 6 is incorporated into the decorative film 10 as a layer structure. Since the surface printing layer 14 of the decorative film 10 is transparent or missing in the portion that forms the metallic decoration portion 6, the thin metallic layer 11 is visible from the surface in the metallic decoration portion 6, A decoration with a metallic luster is obtained. Here, the thin-film metal layer 11 includes a heat insulating resin layer 12 on the back side thereof, and is protected from the heat of the molten resin during film insert injection molding. It is as rich as the plating process.
  On the other hand, since the thin film metal layer 11 is covered with the opaque surface printing layer 14 in the portion other than the metallic decoration portion 6 of the design surface 4, the portion is based on the surface printing layer 14 that does not depend on the gloss of the thin film metal layer 11. Decoration is obtained. Further, in the decorative film 10 according to the present invention, the thin film metal layer is incorporated as a layer structure. However, since the thin film metal layer 11 can transmit light, all of the decorative film 10 in the illumination unit 5 can be used. Light can be transmitted through the layer, and the illumination unit 5 can appropriately emit light by illumination light from the back surface of the panel.
  As described above, according to the configuration of the present invention, it is possible to form the illumination part and a glossy metallic decoration part on a single decorative film, and to make the illumination panel into one part. Further, unlike the plating process or foil stamping which locally forms a metal thin film, the thin film metal layer is incorporated into the decorative film as a layer structure, and thus can be manufactured at a lower cost and easier than the foil stamping.
  Moreover, in the illumination type panel of this invention, it is proposed that the film thickness of the said thin film metal layer is 300-800 mm. In such a case, the thin-film metal layer has both a gloss suitable for forming a metallic decoration part and a light transmission suitable for forming an illumination part.
  Further, the present invention is a method for manufacturing an illumination type panel including a lighting part that emits light by illumination from the back side and a metallic decoration part having a metallic luster on a design surface, and has a metallic luster, And a thin-film metal layer capable of partially transmitting light, a heat-insulating resin layer having a thickness of 100 μm or more provided on the back side of the thin-film metal layer, and provided on the surface side of the thin-film metal layer A film production process for producing a multilayer film comprising a transparent surface resin layer, a printing process for obtaining a decorative film by performing decorative printing on the surface side of the multilayer film, and cutting the decorative film Including a cutting step and a molding step in which the cut decorative film is placed in a molding die to perform film insert injection molding, and the decorative film is laminated and integrated on the surface of the resin base material, and the printing step There The part that will form the metallic decoration part is printed transparently or is not printed, the part that does not form the metallic decoration part is opaque printing, and further the illumination part is formed The part which becomes becomes the manufacturing method of the illumination type panel characterized by performing translucent printing.
  In this manufacturing method, a thin film metal layer that is glossy and transmits light is provided on a multilayer film that constitutes a decorative film, and opaque printing is performed on the surface side of the thin film metal layer. Thus, the decorations not depending on the thin film metal layer are applied to the portions other than the metallic decoration part, and at the same time, the decoration by the thin film metal layer is applied only to the metallic decoration part. In such a manufacturing method, it is not necessary to locally form a metal thin film on the decorative film, and the decorative film including the thin metal layer can be manufactured inexpensively as a long film. Compared with the method of forming a metallic decorative part by foil stamping, the illumination type panel can be manufactured inexpensively and easily. Further, since the thin metal layer transmits light, it does not hinder the translucency of the illumination unit. Furthermore, by providing a heat insulating resin layer on the back side of the thin film metal layer of the decorative film, it is possible to suppress the gloss of the thin film metal layer from being deteriorated by the heat of the molten resin in the molding process.
  Since the illumination panel of the present invention can form both the illumination part and the metallic decoration part with a single decorative film, it is lower than the conventional illumination panel in which the metallic decoration part is formed as a separate part. Can be manufactured at low cost. Further, the thin film metal layer backed by the heat insulating resin layer is not whitened, and the metallic decorative portion has a gloss equivalent to that formed by plating. Furthermore, since the metallic decoration part and the other decoration part can be formed by a single decorative film, the design surface can be made seamless and rich in design. Therefore, according to the illumination type panel of the present invention, an illumination type panel having a glossy metallic decoration part can be realized at low cost. Moreover, according to the manufacturing method of the illumination type panel of this invention, the illumination type panel rich in metallic luster can be manufactured easily.
  The illumination type panel of the present invention is formed by laminating and integrating a decorative film on the surface of a resin base material, and includes an air conditioner operation part, a shift lever operation part, a smart key, a scuff plate, a meter bezel, a handle for an automobile. It is arranged on a bezel or the like.

Examples of the resin base material include ABS resin, polycarbonate ABS, polycarbonate, polypropylene, and acrylic resin. The resin substrate may be a multicolor molded product.
  The decorative film is laminated and integrated on the surface of the resin base material by film insert injection molding or the like. As shown in FIG. 1, the decorative film 10 has a thin film metal layer 11 that can partially transmit light, and a light having a thickness of 100 μm or more provided on the back side of the thin film metal layer 11. It has a multilayer structure comprising a heat insulating resin layer 12, a transparent surface resin layer 13 provided on the surface side of the thin film metal layer 11, and a surface printed layer 14 printed on the surface side of the surface resin layer 13. . In the decorative film 10, it is desirable that the surface resin layer 13, the thin metal layer 11, and the heat insulating resin layer 12 are formed over substantially the entire surface of the decorative film 10.
  The thin metal layer 11 reflects part of light and transmits part of light, and a vacuum deposited film formed by vacuum deposition on a resin film or a sputtered film formed by sputtering on a resin film is suitable. Used. In the case of using a vacuum deposited film or a sputtered film, the resin film serving as the base material constitutes part or all of the surface resin layer 13 or the heat insulating resin layer 12. The material of the thin film metal layer 11 is not particularly limited, but preferable examples include aluminum, indium, nickel, chromium, and stainless steel. The film thickness of the thin metal layer 11 is preferably 300 to 800 mm, and more preferably 400 to 700 mm. If the thickness is 300 mm or more, the thin film metal layer 11 has a metallic luster equivalent to that of the plating treatment, and if it is 400 mm or more, a more preferable metal luster is obtained. Moreover, if the thickness is 800 mm or less, the illumination unit 5 can sufficiently transmit light from the back surface, and if it is 700 mm or less, it can transmit a more sufficient amount of light.
  The material of the surface resin layer 13 is not particularly limited, but PET resin, acrylic resin, polycarbonate, and the like are preferably used. The surface resin layer 13 may be a multi-layered resin layer. Although the thickness of the surface resin layer 13 is not specifically limited, About 25-200 micrometers is preferable. If the thickness is 25 μm or more, the thin metal layer 11 can be sufficiently protected, and if it is 200 μm or less, preferable formability is obtained.
  Although the material of the heat insulation resin layer 12 is not specifically limited, ABS resin, a polypropylene, etc. are used suitably. The heat insulating resin layer 12 may be a multi-layered resin layer. The thickness of the heat insulating resin layer 12 needs to be 100 μm or more, and preferably 150 μm or more. If the thickness is 100 μm or more, the thin film metal layer 11 can be protected from heat during film insert injection molding, and the thinning of the thin film metal layer 11 can be sufficiently suppressed. If the thickness is 150 μm or more, the thin film metal layer 11 can be reliably suppressed. From the viewpoint of moldability, the thickness of the heat insulating resin layer 12 is preferably 500 μm or less.
  The surface print layer 14 is formed by printing on the surface of the surface resin layer 13. As the printing method, a printing method similar to that of the existing decorative film 10 such as gravure printing, flexographic printing, and offset printing is preferably used.
  In the portion where the metallic decoration portion 6 is formed, the surface print layer 14 is made transparent or the surface print layer 14 is omitted. Thereby, in the said metallic tone decoration part 6, the thin film metal layer 11 becomes visible and the glossy metallic appearance is obtained. It is proposed that the metallic decoration 6 is backed with resin or ink that does not transmit light from the back side. With such a configuration, the illumination from the back side of the illumination type panel does not pass through the metallic decoration 6 and the metallic luster is not easily lost.
  The portions other than the metallic decorative portion 6 make the surface print layer 14 opaque. Thereby, in the said part, the thin-film metal layer 11 is interrupted | blocked by the surface printing layer 14, and is not visually recognized, but the decoration based on the surface printing layer 14 is obtained. In addition, at least a portion forming the illumination unit 5 has the light-transmitting surface printing layer 14 with light-transmitting ink such as white, orange, and green. According to such a configuration, when light is applied to the illumination unit from the back side of the decorative film 10, the light is transmitted through the heat insulating resin layer 12, the thin metal layer 11, the surface resin layer 13, and the surface printed layer 14, thereby illuminating. The part 5 emits light.
  In the illumination type panel of the present invention, the decorative film 10 can have a layer structure other than the heat insulating resin layer 12, the thin metal layer 11, the surface resin layer 13, and the surface print layer 14. For example, a resin layer can be further provided on the front surface side of the surface print layer 14, and a print layer can be provided on the back surface side of the heat insulating resin layer 12. Moreover, the surface resin layer and the heat insulating resin layer can include an adhesive layer made of an adhesive.
  In the illumination type panel of the present invention, in addition to the metallic decoration part 6, a part of the surface printing layer 14 is made of bright ink, so that a decorative part made of bright ink is applied to a part other than the metallic decoration part 6. It is also possible to provide. The “metallic decoration part” according to the present invention refers to a decorative part with metallic luster of the thin-film metal layer 11, and the inferior metallic luster by printing of glitter ink is the “metallic decorative part” according to the present invention. Is not included.
  The production method of the present invention is characterized in that the thin film metal layer is provided on the decorative film, and the film production process, the printing process, the cutting process, and the molding process can be performed by known methods. . For example, in the film manufacturing process, a multilayer film can be manufactured by bonding or pressure-bonding another resin film or applying a resin coating to a resin film obtained by vacuum-depositing or sputtering a metal. In the printing process, a printing method similar to that for an existing decorative film, such as gravure printing, flexographic printing, and offset printing, can be employed. And a shaping | molding process can be performed by the film insert injection molding similar to the existing illumination type panel. In addition to the above steps, various processes can be combined with the manufacturing method of the present invention. For example, it is proposed to perform a shaping process on the decorative film before the molding step. Although the method of shaping is not particularly limited, vacuum forming, pressure forming, vacuum / pressure forming or the like is preferably used.
<Example>
The illumination type panel 1 of a present Example is an illumination type panel used for the shift lever operation part of a motor vehicle. As shown in FIGS. 2 and 3, the illuminating panel 1 has the same external shape as the illuminating panel 1a of the conventional shift lever operation section shown in FIG. That is, the illumination type panel 1 is formed by disposing the fixing portion 3 on the peripheral portion of the panel body 2, and the design surface 4 is formed on the entire upper surface of the panel body 2, and the lever opening portion The letters “P”, “R”, “N”, and “D” written in the display area 8 on the left side of FIG. 7 constitute the illuminating unit 5, and are formed on the bowl-shaped peripheral portion of the lever opening 7. A metallic decoration 6 is provided.
  As shown in FIG. 4, the illumination type panel 1 is formed by integrally laminating a decorative film 10 on the surface of a resin base material 9. The resin base material 9 includes a light-transmitting resin portion 21 made of a light-transmitting resin that lines the illumination portion 5 and a light-impermeable resin portion 22 made of a black resin. An illumination opening 23 is formed in the peripheral portion of the light-impermeable resin portion 22 around the illumination portion 5, so that the illumination film 10 is not blocked by the light-impermeable resin portion 22 from the back surface side. It comes to hit.
  As shown in FIG. 4, the decorative film 10 is laminated on the entire upper surface of the panel main body 2 to form the entire design surface 4 including the metallic decoration portion 6. As shown in FIGS. 5 and 6, the decorative film 10 includes a thin film metal layer 11, a heat insulating resin layer 12 provided on the back surface of the thin film metal layer 11, and a surface provided on the surface side of the thin film metal layer 11. It is comprised by the resin layer 13 and the surface printing layer 14 provided in the surface side of this surface resin layer 13. FIG.
  The thin metal layer 11 is made of an aluminum thin film having a thickness of about 500 mm, reflects a part of the irradiated light and transmits a part of the light, thereby having a metallic luster and the back side. The light from is partially transmitted to the surface side.
  The heat insulating resin layer 12 is composed of an ABS resin film having a translucency of about 200 to 250 μm in thickness.
  The surface resin layer 13 includes a transparent PET resin layer 15 having a thickness of about 15 to 30 μm in contact with the surface of the thin film metal layer 11 and a transparent PMMA resin layer 16 in contact with the surface of the PET resin layer 15. The PET resin layer 15 constitutes a base material when the thin film metal layer 11 is formed, and the PMMA resin layer 16 protects the thin film metal layer 11 and constitutes a printing surface of the surface printing layer 14.
  The surface printing layer 14 is composed of an opaque ink having a thickness of about 3 to 20 μm, and the decoration of the design surface 4 is formed by the surface printing layer 14. The portion constituting the illumination part 5 of the surface printing layer 14 is formed of white ink and has translucency, and the display area 8 other than the illumination part 5 is formed of black ink and does not transmit light. It has become. The remaining part of the design surface 4 is decorated with silver ink. Moreover, the surface printed layer 14 is missing only in the portion where the metallic decoration portion 6 is formed, and the metallic luster of the thin metal layer 11 is visible only in that portion.
  Thus, in this configuration, in the metallic decoration part 6, the thin metal layer 11 of the decorative film 10 is visually recognized from the surface, and the metallic decoration part 6 has a metallic gloss. On the other hand, since the thin film metal layer 11 is covered with the opaque surface printing layer 14 in the portion other than the metallic decoration portion 6, the gloss of the thin film metal layer 11 is not visually recognized in this portion, and only the surface printing layer 14 is present. The decoration by is visible. Moreover, in the illumination part 5, since all the heat insulation resin layer 12, the thin metal layer 11, the surface resin layer 13, and the surface printing layer 14 can permeate | transmit light, the surface of the illumination part 5 by illumination from a back surface side Will emit light.
  Next, the manufacturing method of the illumination type panel 1 of a present Example is demonstrated. The illumination type panel 1 of a present Example is manufactured by performing each process demonstrated below in order.
<Film production process>
First, a multilayer film constituting the decorative film 10 is manufactured. The multilayer film is formed by laminating the PMMA resin layer 16, the PET resin layer 15, the thin metal layer 11, and the heat insulating resin layer 12 in this order from the front side, and on the front and back of the vacuum-deposited PET resin film, It is manufactured by adhering the ABS resin film constituting the layer 12 and the PMMA resin film constituting the PMMA resin layer 16. Since each film can be manufactured and bonded by a well-known method, detailed description is omitted.
<Printing process>
In the printing process, a decorative film 10 is obtained by printing a required decorative pattern on the multilayer film manufactured in the film manufacturing process and forming a surface print layer 14 on the surface of the PMMA resin layer. Here, the portion that will form the metallic decoration portion 6 is not printed, and the portion that will form the illumination portion 5 is translucent printed with white ink. Such a printing process can be performed by a printing method similar to that for a decorative film according to a conventional illumination type panel.
<Shaping process>
In the shaping step, the decorative film 10 is shaped to match the shape of the mold by pressure forming. Such molding can be performed under the same conditions as a conventional decorative film, and can also be performed by vacuum molding or vacuum / pressure forming.
<Cutting process>
In the cutting process, the decorative film 10 shaped in the shaping process is cut according to the shape of the mold.
<Molding process>
In the molding process, the decorative film 10 cut in the cutting process is set in a mold so that the surface printing layer 14 is in contact with the mold surface, and film insert injection molding is performed. The lighting panel 1 in which the decorative film 10 is laminated and integrated on the surface of the resin base material 9 is manufactured. In this embodiment, since the resin base material 9 is composed of a transparent resin that forms the light-transmitting resin portion 21 and a black resin that forms the light-impermeable resin portion 22, it is manufactured by two-color injection molding. The Such a molding process can be performed by using a molding die and molding conditions similar to those of a conventional lighting panel.
  As described above, according to the illumination type panel 1 of the present embodiment, the entire design surface 4 including the illumination part 5 and the metallic decoration part 6 can be formed by a single decorative film 10. Therefore, the illumination panel 1 can be made into one part and the entire design surface 4 can be made seamless. In particular, in this embodiment, the thin metal layer 11 is incorporated as a layer structure on the entire surface of the decorative film 10, so that the metallic decoration can be performed without performing a process of locally forming the thin metal film like foil stamping. There exists an advantage that the part 6 can be formed easily. In addition, the decorative film 10 in which the thin metal layer 11 is incorporated over the entire surface is rich in versatility and can be manufactured by a well-known method and can be mass-produced. Therefore, the manufacturing process can be simplified as compared with the case of foil pressing. Moreover, since the thin metal layer 11 has a metallic luster and is of a half mirror specification that transmits light, even if it is formed on the entire surface of the decorative film 10, the light transmission of the illumination unit 5 is achieved. Does not inhibit sex.
  Moreover, since the heat insulation resin layer 12 is formed in the back surface of the thin film metal layer 11, the illumination type panel 1 of a present Example is the molten resin inject | emitted on the back surface of the film 10 for decoration at the time of film insert injection molding. Is not easily transmitted to the thin film metal layer 11, and the thin film metal layer 11 is not whitened by the heat of the molten resin. Therefore, in the illumination type panel 1 of the present embodiment, the metallic decoration part 6 rich in metallic luster can be realized by the thin film metal layer 11.
  In addition, the illumination type panel in this invention can add a various change in the range which does not deviate from the summary of not only the form of the said Example but this invention. For example, in the embodiment, the resin base material 9 is composed of two color resin parts of the light-transmitting resin part 21 and the light-impermeable resin part 22, but the resin base material is one kind of resin. It may be configured, and it is not necessary to back the entire surface of the decorative film with a resin base material. In the examples, the surface resin layer of the decorative film was composed of two layers, a PMMA resin layer and a PET resin layer. However, the surface resin layer and the heat insulating resin layer may be a single layer structure or a multilayer structure. It doesn't matter.
It is a conceptual diagram which shows the layer structure of the decorative film which concerns on this invention. It is a perspective view of the illumination type panel 1 of an Example. It is a top view of the illumination type panel 1 of an Example. It is AA sectional drawing in FIG. FIG. 5 is an enlarged view of a portion B in FIG. 4.
