Description

  The present invention relates to a method for manufacturing a decorative molded product such as an exterior panel or a decorative plate used as an exterior member of an automobile, an electric product, or the like, and a decorative molded product obtained by the manufacturing method.

  An emblem that is one of vehicle exterior members is a decorative molded product in which three-dimensional characters and symbols are formed inside a transparent resin plate. These three-dimensional characters and symbols are often decorated in a metallic tone with a metallic luster. The emblem 1 shown in FIGS. 20 and 21 will be described as an example of such a decorative molded product. The emblem 1 includes a disk-shaped surface-side resin molded body 2 that is transparent and has a convexly curved upper surface, and a disk-shaped back-side resin molded body 3 that is fixed to the back side of the surface-side resin molded body 2. ing. Between the front side resin molded body 2 and the back side resin molded body 3, there are provided a decoration layer 4 and an adhesive layer 5 representing “English letter E with circles”, and this “E” is three-dimensional. The metallic tone is exhibited.

Such an emblem 1 is manufactured by forming metal characters or symbols using a masking technique or a metal deposition technique described in Japanese Patent Laid-Open No. 2001-266687, and the manufacturing method will be described. First, as shown in FIG. 22, the front surface side resin molded body 2 having a curved upper surface and a display recess 2 a corresponding to “E” is formed on the back surface, and a masking layer is formed on the outer edges of the top surface and the back surface. 6 is formed.

JP 2001-266687 A

The emblem 1 obtained as described above can visually recognize a three-dimensional “E” in a metallic style and has a high-class feeling, but has a large number of manufacturing steps (number of processes) and a large number of parts, so that the manufacturing cost is high. Is expensive. In particular, since the number of steps after forming the surface-side resin molded body 2 is large, the surface-side resin molded body 2 is easily damaged, and handling during manufacture is difficult.
Further, since the masking layer 6 formed on the upper surface is formed up to the outer edge of the back surface so as to completely cover the edge of the upper surface, a metal-like circular ring that appears to surround “E” is formed in the outer peripheral edge shape. The design value has become insufficient.

  The present invention has been made against the background of the prior art as described above. That is, an object of the present invention is to provide a technique that can reduce the manufacturing cost with a small number of manufacturing steps and parts. Another object of the present invention is to provide a technology in which design restrictions on the manufacturing method are unlikely to occur.

In order to achieve the above object, the present invention is configured as follows.
In a method for producing a decorative molded article, comprising a front side molded body on the front side, a back side molded body on the back side, and a decorative film formed between a resin film having a decorative layer and sandwiched between the two molded bodies. Then, the decorative film deformed into a three-dimensional shape is placed in a molding die, and one side of the decorative film is integrally formed with either the front-side molded body or the back-side molded body. Provided is a method for producing a decorative molded product, in which the other side and either the front side molded body or the back side molded body are further integrally molded.

In the present invention, the decorative film sandwiched between the front-side molded body and the back-side molded body to decorate the decorative molded product, so that either of the molded bodies is decorated. Compared to the manufacturing method, the number of manufacturing steps can be reduced. For example, when forming a vapor deposition layer as a “decorative layer” on a molded body, in the prior art, a masking layer is formed on an unnecessary portion of the vapor deposition layer in the molded body before the vapor deposition step, and the molded body is formed after the vapor deposition step. It is necessary to remove the formed masking layer. However, in the present invention, since the decorative film having the vapor deposition layer is integrally formed with the molded body, the masking layer formed on the molded body can be eliminated, and the number of manufacturing steps can be reduced. Furthermore, since the front-side molded body and the back-side molded body are formed by integral molding with the decorative film, the number of parts can be reduced as compared with the conventional manufacturing method in which each is formed separately.
As described above, the manufacturing cost can be reduced as compared with the conventional manufacturing method.
Furthermore, since the number of steps after forming the front-side molded body on the front side is small compared to the conventional manufacturing method in which a decorative layer is provided on the front-side resin molded body, the front-side molded body can be hardly damaged. High yield production can be realized.

  Moreover, since a decorating film decorates a decorative molded product as mentioned above, it can decorate over the whole surface fixed to the decorating film in a front side molded object or a back side molded object. For example, when forming a vapor deposition layer on a molded body, the conventional technology as described above requires a masking layer on the adjacent surface of the vapor deposition surface of the molded body, and masks the outer edge of the vapor deposition surface to completely cover the adjacent surface. A layer is formed, and the outer periphery of the vapor deposition layer on the vapor deposition surface is formed in a border shape. However, in the present invention, since the decorative film having the vapor deposition layer is integrally formed with the molded body, it can be decorated with the vapor deposition layer over the entire surface of the decorative film fixing surface, which makes it difficult to cause design restrictions on the manufacturing method. be able to.

  Such a decorative film is deformed in advance into a three-dimensional shape before being integrally formed with the front-side molded body and the back-side molded body. When the decorative film is placed in a molding die without being deformed into a three-dimensional shape and integrally molded with one side of the decorative film for the first time, the decorative film is injected from the gate side of the cavity by the injected molten resin. Due to the deformation, the decorative film is easily deformed and easily broken. However, if the decorative film is deformed into a three-dimensional shape in advance as in the present invention, this deformation process can be performed while specifying the extended portion of the decorative film with a mold or jig, so that the deformation biased to the decorative film is It is difficult to get up and the decorative film can be made difficult to tear. The three-dimensional shape of the decorative film can be formed so as to have a convex or concave curved portion corresponding to a display element such as a character or symbol to be displayed. For example, if the decorative film is deformed into a three-dimensional shape having a convex curved portion corresponding to the display element, this display element can be visually recognized as if it is raised on the near side, and the decorative film corresponds to the display element. If the display element is deformed into a three-dimensional shape having a concave curved portion, the display element can be visually recognized as if it has sunk into the back side.

After integrally molding one side of the decorative film and either the front side molded body or the back side molded body, unnecessary portions of the integrally molded decorative film are cut and removed, and the other side of the decorative film and the front side molded body or Either one of the back side molded bodies can be integrally molded. When the decorative film is deformed into a three-dimensional shape or in the first integral molding of the one surface of the decorative film and the molded body, it is necessary to position the decorative film with respect to a mold or the like. However, in the second integral molding, positioning in the mold of the decorative film becomes unnecessary because the molded body that has already been formed can be positioned in the cavity. Therefore, if the unnecessary portion of the decorative film is cut and removed before the second integral molding, the finishing process of the decorative film performed after the second integral molding can be omitted, and the decorative molded product is hardly damaged. be able to.
In the second integral molding, if the molded body is formed so as to cover the outer edge of the decorative film, the decorative film can be sealed with the front-side molded body and the back-side molded body. If a decorative film can be sealed, when a metal layer is provided as a decorative layer, the metal layer can be made difficult to corrode or oxidize, and the metallic luster can be made less likely to deteriorate over time.

The decorative film can be formed by stacking a plurality of resin films. If it does in this way, "decorative layers", such as a vapor deposition layer and a colored layer, can be pinched | interposed between resin films, and a decorative layer can be protected at the time of a three-dimensional deformation | transformation or integral molding.
Furthermore, such a decorative film can be formed by combining a resin film having a high fixing force with the decorative layer and a resin film having a high fixing force with the molded body. If it does in this way, when forming a decorating film, an adhesion layer can be omitted as much as possible, and a manufacturing man-hour can be decreased. For example, a vapor deposition layer is formed on a resin film that can be easily deposited, a resin film that is easily fixed to the front side molded body is laminated on one side of the resin film, and a resin film that is easily fixed to the back side molded body on the other side. If the layers are stacked, the formation of the adhesive layer can be omitted in the vapor deposition forming process or the integral molding process. Many adhesive layers contain additives for the purpose of enhancing wettability with the adherend or defoaming when applied. Then, this additive may cause the adhesive layer to become turbid, and the turbid adhesive layer lowers the gloss luminance of the deposited layer. For this reason, if the adhesive layer can be omitted, it is possible to prevent a decrease in gloss luminance of the vapor deposition layer due to the adhesive layer.
Furthermore, if a vapor deposition layer is formed on a resin film that is easy to adhere to the front side molded body and easy to form by vapor deposition, and this vapor deposition layer is sandwiched between resin films that are easy to adhere to the back side molded body, two resin films are laminated. A decorative film having a thin total thickness can be formed. Thus, a decorative film with a thin total thickness can suppress rigidity small, and can make it easy to form in a three-dimensional shape at the time of aperture deformation. The decorative film having a thin total thickness can secure a wide area near the gate in the cavity during integral molding, and can easily pass through the molten resin injected from the gate.

  The decorative film can be formed of a single resin film. If it does in this way, the lamination process of the resin films can be omitted, and the number of manufacturing steps and the number of parts of the decorative film can be reduced.

  The molded body integrally molded with one surface of the decorative film can be molded with a resin having a higher deflection temperature than the molded body integrally molded with the other surface of the decorative film. The molded body integrally molded with one surface of the decorative film is a molded body formed by the first integral molding. If it does in this way, when performing the 2nd integral molding with the other side of a decoration film, the molded object which adheres to one side of a decoration film can be made hard to heat-deform, and a decoration film is hard to be torn. can do. More preferably, a thermoplastic resin having a deflection temperature under load of 100 ° C. or higher can be used for the molded body integrally formed with one surface of the decorative film. The deflection temperature under load is measured according to JIS K 7191 (1.8 MPa). Examples of the thermoplastic resin having a deflection temperature under load of 100 ° C. or higher include polycarbonate resin, polyacetal resin, polyphenylene oxide resin, polyphenylene ether resin, polyphenylene sulfide resin, and polyether ether ketone resin.

  The decorative film can be provided with a resin film made of a resin having a higher deflection temperature than that of the molded body integrally formed with the other surface. If it does in this way, the heat resistance of a decoration film can be improved and when performing the 2nd integral molding with the other side of a decoration film, a decoration film can be made hard to be torn. More preferably, a resin film made of a thermoplastic resin having a deflection temperature under load of 100 ° C. or more can be provided. Examples of the thermoplastic resin that can be formed into a film at a deflection temperature under load of 100 ° C. or higher include polycarbonate resin, polyacetal resin, polyphenylene oxide resin, polyphenylene ether resin, polyphenylene sulfide resin, and polyether ether ketone resin. Among them, in order to facilitate the three-dimensional deformation of the decorative film, a polycarbonate resin, a polyacetal resin, a polyether ether ketone resin, etc. having a deflection temperature under load of 100 ° C. to 150 ° C. are preferable, and a polycarbonate resin with higher transparency is preferable. .

  A decorative film formed by laminating a plurality of resin films is formed of a resin film of the same material as that of a molded body integrally formed with one surface of the one surface side, and is the same as that of a molded body integrally molded with the other surface of the other surface side. It can be formed of a resin film made of a material. The same material can be integrally molded so that it can be firmly fixed. In this way, both sides of the decorative film can be firmly fixed to the molded body, eliminating the formation of an adhesive layer in the integral molding process. be able to. Therefore, the number of manufacturing steps can be reduced.

  The decorative film can include a discontinuous vapor deposition layer of metal. In this way, the discontinuous vapor deposition layer easily transmits radio waves and does not easily interfere with wireless communication or radar. Therefore, the decorative molded product of the present invention can be used as a cover member such as a millimeter wave radar device or a microwave radar device, or these. It can be used as an emblem of a vehicle equipped with the device. Moreover, when a discontinuous vapor deposition layer deform | transforms a decoration film into a three-dimensional shape, it is hard to produce a crack and can implement | achieve a three-dimensional metal decoration. Examples of the metal include tin, indium, and silver.

  The decorative film can be provided with a metallic film made of a laminate of thin film resin films. Since the laminated body of thin film resin films exhibits a metallic luster by utilizing light refraction, it is possible to achieve metallic decoration without using metal. Therefore, decorative molded products can be used as cover members for millimeter wave radar devices, microwave radar devices, etc., and emblems for vehicles equipped with these devices. Can be realized. Examples of the material of the thin film resin film include a polyethylene terephthalate resin film, a polyamide resin film, and a liquid crystal polymer film. In such a thin film resin film, the thickness of one layer is 0.050 μm to 0.500 μm, and 500 to 2000 layers are laminated as a laminate.

  The deformed decorative film is placed in a molding die, and one side of the decorative film and the back side molded body that is the back side are integrally molded, and the other side and the front side molding of the integrally formed decorative film are formed. About the manufacturing method of the decorative molded product which shape | molds a body further integrally, resin which forms a front side molded object can be made into a high fluidity resin. If it does in this way, when shape | molding a front side molded object, molten resin can flow easily in a cavity, it can make it difficult to heat-deform a back side molded object, and it can also make a decorative film difficult to tear. The high fluidity resin preferably has a melt flow rate (MFR) of 10 g / 10 min or more. This MFR is measured according to JIS K 7210, and the measurement conditions are 300 ° C. · 1.20 kgf, or 230 ° C. · 3.80 kgf.

  In addition, the present invention provides a decorative film in which a resin film having a decorative layer is deformed and formed into a three-dimensional shape, a transparent front-side molded body that is integrally fixed to the surface side of the decorative film, and the decorative There is provided a decorative molded product including a back-side molded body that is integrally fixed to the back side of a film.

It is possible to realize abundant design variations by making difficult design restrictions.

  Furthermore, since the decorative film is deformed and formed into a three-dimensional shape, the decorative molded product can be three-dimensionally decorated. For example, if the display element is deformed into a three-dimensional shape having a convex curved portion corresponding to a display element such as a character or symbol to be displayed, the display element can be visually recognized as if it is raised to the near side, and corresponds to the display element. If the display element is deformed into a three-dimensional shape having a concave curved portion, the display element can be visually recognized as if sinking to the back side.

  The decorative film can be formed by laminating a plurality of resin films. If it does in this way, a decoration layer can be protected at the time of a three-dimensional deformation | transformation and integral molding, and the decoration with a good appearance can be implement | achieved. In addition, if a “decorative layer” is combined with a resin film with a high adhesive strength or a molded product with a resin film with a high adhesive strength, a highly durable decorative molded product can be realized. And the deterioration of the visibility due to the adhesive layer can be prevented.

  The decorative film can be formed of a single resin film. If it does in this way, the lamination process of the resin films can be omitted, the number of manufacturing steps and the number of parts of the decorative film can be reduced, and an inexpensive decorative molded product can be realized.

  Deflection temperature under load from the molded body that is fixed to either the front side or the back side of the decorative film by integral molding. Can be formed of a high resin. In this way, if a resin having a high deflection temperature is formed by the first integral molding, when the second integral molding is performed, the molded body that has already been molded can be hardly thermally deformed. Can be hard to tear. Therefore, a decorative molded product with good appearance quality can be realized. More preferably, a thermoplastic resin having a deflection temperature under load of 100 ° C. or higher can be used as the resin having a high deflection temperature under load.

  The decorative film can include a resin film made of a resin having a higher deflection temperature under load than at least one of the front-side molded body or the back-side molded body. If it does in this way, the heat resistance of a decoration film can be improved and it can make it difficult to tear a decoration film when performing the 2nd integral molding of a decoration film. Therefore, a decorative molded product with good appearance quality can be realized.

In the present embodiment, the discontinuous vapor deposition layer 14c is decorated in a metallic style, but a thin-film metal layer such as aluminum, chromium, nickel, stainless steel, copper, gold, or titanium can also be used.

A method for manufacturing the emblem 11 will be described.
First, as shown in FIG. 3, a discontinuous vapor deposition layer 14c is formed on a resin film 14a, an adhesive layer 14d is applied to the discontinuous vapor deposition layer 14c, and the resin film 14b is fixed by the adhesive layer 14d. The decorative layer 14 is formed by applying a colored layer 14e on the outer surface of the film 14a. The decorative film 14 is provided with several through holes 14f at the outer edge portion for positioning with respect to the mold in the drawing deformation process or the integral molding process.

  Next, as shown in FIG. 4, the decorative film 14 is compressed and deformed with the drawing dies 15 and 16 for drawing deformation to form a curved portion corresponding to the English letter “E” on the decorative film 14. A fitting recess 15 a into which the decorative film 14 is fitted is formed in the drawing die 15 that contacts the surface side of the decorative film 14. The fitting recess 15a is provided with an engagement pin 15b that engages with the through hole 14f of the decorative film 14, and a display recess 15c that is recessed corresponding to the letter "E" is formed. A display projection 16 a that curves and deforms the decorative film 14 is formed in the display recess 16 c of the aperture die 15 so as to protrude from the aperture die 16 that contacts the back surface side of the decorative film 14.

  Then, as shown in FIG. 5, the deformed decorative film 14 is inserted into the molding dies 17 and 18 of the back-side molded body 13, and the back surface of the decorative film 14 and the back-side molded body 13 are integrally molded. A fitting recess 17 a into which the decorative film 14 is fitted is formed in the molding die 17 that comes into contact with the surface side of the decorative film 14. The fitting recess 17a is provided with an engaging pin 17b that engages with the through hole 14f of the decorative film 14, and a display recess 17c that is recessed corresponding to the letter “E” is formed. In the molding die 18 that comes into contact with the back side of the decorative film 14, a cavity 18a for molding the back side molded body 13 and an injection gate 18b for injecting a molten resin into the cavity 18a are formed.

  Thereafter, as shown in FIG. 6, unnecessary portions of the decorative film 14 formed integrally with the back side molded body 13 are cut and removed. The punching blade 19 used in this step is formed in accordance with the outer peripheral edge of the back-side molded body 13.

Finally, as shown in FIG. 7, an integrated product of the cut decorative film 14 and the back side molded body 13 is inserted into the molding dies 20 and 21 of the front side molded body 12, and the surface of the decorative film 14 is inserted.

A fitting recess 21 a into which the back-side molded body 13 is fitted is formed in a molding die 21 into which an integrated product of the decorative film 14 and the back-side molded body 13 is inserted.
The emblem 11 is obtained by such a manufacturing method.

  According to the manufacturing method of the emblem 11 and the emblem 11, a conventional manufacturing method using a masking method for decorating with the decorative film 14 sandwiched between the front side molded body 12 and the back side molded body 13 by integral molding. Compared with, manufacturing man-hours can be reduced. Furthermore, the number of parts can be reduced as compared with the manufacturing method of the prior art in which the front side molded body and the back side molded body, which are separately formed, are fixed. As described above, the manufacturing cost can be reduced as compared with the conventional manufacturing method. Moreover, since the number of processes after forming the front side molded body 12 on the front side is small, the front side molded body 12 can be made hard to be damaged, and high yield production can be realized.

  Since the decorative film 14 decorates the emblem 11, it can be decorated over the entire surface of the decorative film 14 fixing surface in the front side molded body 12 and the back side molded body 13, and the outer peripheral edge formed by a conventional manufacturing method. Can be eliminated. Therefore, design restrictions on the manufacturing method can be made difficult to occur.

Since the decorative film 14 is formed by laminating two resin films 14a and 14b, the discontinuous vapor deposition layer 14c can be sandwiched between the resin films 14a and 14b, and is discontinuous at the time of drawing deformation or integral molding. The vapor deposition layer 14c can be protected.
If the discontinuous vapor deposition layer 14c is formed on the resin film 14a, and the front side molded body 12 made of the same material as the resin film 14a is integrally formed, the adhesive layer can be omitted on the surface side from the discontinuous vapor deposition layer 14c. Therefore, it is possible to prevent a decrease in gloss luminance of the discontinuous vapor deposition layer 14c.
Furthermore, since the decorative film 14 is a thin film having a total thickness obtained by laminating two resin films 14a and 14b, the rigidity of the decorative film 14 can be kept small, and it can be easily formed into a three-dimensional shape when the diaphragm is deformed.

  Since the decorative film 14 is drawn and deformed into a three-dimensional shape by the drawing dies 15 and 16 in advance before being integrally formed with the back-side molded body 13, it is difficult for the deformation to occur and it is difficult to break. Therefore, it is possible to visually recognize the English character “E” accurately represented so as to be raised toward the near side.

  Since the decorative film 14 is integrally formed with the back surface and the back side molded body 13, unnecessary portions are cut and removed, and the surface of the decorative film 14 and the front side molded body 12 are integrally molded. The finishing process of the decorative film 14 can be omitted after molding, and the surface of the emblem 11 can be made difficult to be damaged.

  If the back side molded body 13 that is integrally molded with the back surface of the decorative film 14 is formed of a thermoplastic resin having a higher deflection temperature under load than the front side molded body 12, then the surface of the decorative film 14 and the front side molded body 12 are integrally molded. When doing, the back side molded object 13 can be made difficult to deform | transform, and the decorative film 14 can also be made hard to tear.

  If at least one of the resin films 14a, 14b constituting the decorative film 14 is formed of a thermoplastic resin having a higher deflection temperature under load than the front-side molded body 12, the surface of the decorative film 14 that is integrally molded for the second time The decorative film 14 can be made difficult to tear during integral molding with the front-side molded body 12.

  Since the decorative film 14 includes the discontinuous vapor deposition layer 14c, the emblem 11 can be used as a cover member such as a millimeter wave radar device or a microwave radar device or as an emblem of a vehicle on which these devices are mounted. Moreover, the discontinuous vapor deposition layer 14c is hard to crack at the time of drawing deformation, and can realize three-dimensional metal decoration.

It is comprised from the colored layer 22f currently formed in the outer surface by the side of the molded object 12. For example, the discontinuous vapor deposition layer 22d is formed on the resin film 22c that can be integrally formed with the back-side molded body 13, and this resin film 22c is used as the back surface side of the decorative film 22, and the discontinuous vapor deposition layer 22d is interposed through the adhesive layer 22e. A resin film 22b made of a thermoplastic resin having a higher deflection temperature than that of the front molded body 12 is laminated, and a resin film 22a that can be integrally formed with the front molded body 12 is further laminated via an adhesive layer 22e. It was set as the surface side.

  Even if it does in this way, the resin film 22c of the back surface side of the decorating film 22 and the back side molded object 13 can be integrally molded, and the resin film 22a of the decorating film 22 and the front side molded object 12 can be integrally molded. And since the thermoplastic resin whose deflection temperature under load is higher than the front side molded object 12 is used for the resin film 22b which comprises the decorative film 22, the surface of the decorative film 22 used as the 2nd integral molding, and the front side molded object 12 The decorative film 22 can be made difficult to tear during the integral molding.

  As shown in FIG. 9, the decorative film 23 of the second modified example is formed on three resin films 23a, 23b, 23c, an adhesive layer 23d sandwiched between them, and an outer surface on the front side molded body 12 side. And a colored layer 23e. For example, a resin film 23b made of a laminate of a thin film resin film is laminated on a resin film 23c that can be integrally formed with the back-side molded body 13 on the back surface side of the decorative film 23, and further, via a bonding layer 23d. A resin film 23a that can be integrally formed with the front-side molded body 12 was laminated, and this resin film 23a was used as the surface side. The resin film 23b made of this laminate has a thickness of one layer of 0.050 μm to 0.500 μm, and the laminate is a laminate of 500 to 2000 layers, and exhibits a metallic luster using light refraction. .

  In this way, since it is possible to achieve metallic decoration without using metal, the emblem 11 is used as a cover member such as a millimeter wave radar device or a microwave radar device, or as an emblem of a vehicle on which these devices are mounted. It can be used, and cracks hardly occur at the time of deformation of the drawing, so that a three-dimensional metallic decoration can be realized.

  According to the manufacturing method and the emblem 41 of the emblem 41, the lamination process of the resin films can be omitted, and the number of manufacturing steps and the number of parts of the decorative film 42 can be reduced. Therefore, an inexpensive emblem 41 can be realized.

  Next, the present invention will be described in more detail by showing specific materials of each member. The first embodiment will be described as a representative example.

Example 1 :
The emblem 11 shown in the first embodiment was manufactured as follows.
A discontinuous vapor deposition layer 14c made of indium is formed on the polymethyl methacrylate resin film 14a, and the polycarbonate resin film 14b is fixed to the discontinuous vapor deposition layer 14c through an adhesive layer 14d. Thereafter, a blue colored layer 14e is applied to the outer surface of the polymethylmethacrylate resin film 14a, and the decorative film 14 is formed by providing four through holes 14f on the outer edge portion.
The decorative film 14 is compressed and deformed by the drawing dies 15 and 16 with the polymethyl methacrylate resin film 14a as the front side, and then inserted into the molding dies 17 and 18 of the back side molded body 13, and the polycarbonate resin is injected and added. The polycarbonate resin film 14b of the decorative film 14 and the back side molded body 13 made of polycarbonate resin are integrally formed.
Unnecessary portions of the decorative film 14 formed integrally with the back-side molded body 13 are cut and removed with a punching blade 19, inserted into the molding dies 20 and 21 of the front-side molded body 12, and a polymethylmethacrylate resin is injected to decorate the film. 14 polymethyl methacrylate resin film 14a and front side molded body 12 made of polymethyl methacrylate resin are integrally molded.
Thus, the emblem 11 of Example 1 was obtained.
In Example 1, since it is difficult to uniformly deposit indium on the polycarbonate resin film, indium is deposited on the polymethyl methacrylate resin film 14a. And the polycarbonate resin film 14b whose load deflection temperature is around 120 ° C. is laminated on the discontinuous vapor deposition layer 14c made of indium by the adhesive layer 14d.

Indium is vapor-deposited on the polymethyl methacrylate resin film 14a, and the front-side molded body 12 made of polymethyl methacrylate resin is integrally formed on the polymethyl methacrylate resin film 14a, so that the adhesive layer is omitted on the surface side from the discontinuous vapor deposition layer 14c. It is possible to prevent a decrease in gloss luminance of the discontinuous vapor deposition layer 14c due to the adhesive layer.
Furthermore, since the decorative film 14 is a thin film having a total thickness obtained by laminating the polymethyl methacrylate resin film 14a and the polycarbonate resin film 14b, the rigidity can be suppressed to be small, and the three-dimensional shape can be easily formed at the time of the deformation of the drawing. be able to.

When integrally molding the front side molded body 12 made of resin, the back side molded body 13 can be made difficult to deform, and the decorative film 14 can also be made difficult to break.

  Since a polycarbonate resin film having a deflection temperature under load of around 120 ° C. is used for the resin film 14b constituting the decoration film 14, the surface of the decoration film 14 and the deflection temperature under load of about 90 ° C., which are integrally molded for the second time, are used. The decorative film 14 can be made difficult to tear during integral molding with the front side molded body 12 made of methyl methacrylate resin.

  Since the decorative film 14 includes the discontinuous vapor deposition layer 14c made of indium, the emblem 11 can be used as a cover member such as a millimeter wave radar device or a microwave radar device or an emblem of a vehicle on which these devices are mounted. Moreover, the discontinuous vapor deposition layer 14c is hard to crack at the time of drawing deformation, and can realize three-dimensional metal decoration.

Example 2 :

A discontinuous vapor deposition layer 22d made of indium is formed on a resin film 22c made of polyethylene terephthalate resin, this polyethylene terephthalate resin film 22c is used as the back side of the decorative film 22, and the discontinuous vapor deposition layer 22d is interposed through an adhesive layer 22e. A resin film 22b made of a polycarbonate resin is laminated, and a resin film 22a made of a polymethyl methacrylate resin is further laminated through an adhesive layer 22e, and this polymethyl methacrylate resin film 22a is set as the surface side (FIG. 8B). ).

  Even in this case, the polyethylene terephthalate resin film 22c on the back surface side of the decorative film 22 and the back-side molded body 13 made of polycarbonate resin can be integrally formed, and the polymethyl methacrylate resin film 22a of the decorative film 22 and the poly The front side molded body 12 made of methyl methacrylate resin can be integrally molded. Since the resin film 22b constituting the decorative film 22 uses a polycarbonate resin having a deflection temperature of about 120 ° C., the surface of the decorative film 22 to be integrally molded for the second time and a poly film having a deflection temperature of about 90 ° C. The decorative film 22 can be made difficult to tear during integral molding with the front-side molded body 12 made of methyl methacrylate resin. Further, since the discontinuous vapor deposition layer 22d is formed on the polyethylene terephthalate resin film 22c, it can be a uniform layer.

Example 3 :
It replaced with the decoration film 14 of the emblem 11 shown in 1st Embodiment, and manufactured using the decoration film 23 as the 2nd modification.
A resin film 23b made of a laminate of a thin film polyethylene terephthalate resin film is laminated on a resin film 23c made of polycarbonate resin on the back side of the decorative film 23 via an adhesive layer 23d, and polymethyl methacrylate is further laminated via an adhesive layer 23d. A resin film 23a made of a resin was laminated, and this polymethyl methacrylate resin film 23a was used as the surface side (FIG. 9). The resin film 23b made of this laminate is obtained by laminating 800 layers of a polyethylene terephthalate resin film having a thickness of 0.125 μm.

  In this way, since it is possible to achieve metallic decoration without using metal, the emblem 11 is used as a cover member such as a millimeter wave radar device or a microwave radar device, or as an emblem of a vehicle on which these devices are mounted. It can be used, and cracks hardly occur at the time of deformation of the drawing, so that a three-dimensional metallic decoration can be realized.
