Description

  The present invention relates to a decorative molded body used for a mobile phone, a portable information terminal, a remote controller for various home appliances, a card remote controller and various keyboards, a housing of an electronic device, and the like, and among them, a key for a push button switch in particular. Regarding the top.

  In recent years, electronic devices have been diversified in design along with multifunctionalization. In particular, in the mobile phone 1 as shown in FIG. 9 that has been widely used not only for business use but also for personal use, not only multi-functionalization including various functions such as a call function, an e-mail function, a shooting function, The diversification of designs for differentiation from other models is ongoing, and competition for new product development is intense from the viewpoint of diversification of designs.

  Among them, there is also a design competition for differentiating from the other models in the key top 2 for the push button switch that forms a part of the surface of the mobile phone 1. And the recent key top 2 design tends to favor metal, pearl, and light-colored colors that match the various colored housings 1a. A decorative layer having such a color tone is formed on the surface of the key top body using the surface.

  The decoration layer can be formed by, for example, applying a paint containing metal powder to the surface of the key top 2 by screen printing or spray coating, or applying a metal layer such as nickel or chromium by wet plating by an electroless method or an electrolytic method. A method of providing (see Patent Document 1), a method of providing a metal layer such as aluminum or chromium on the surface of the key top 2 by dry plating such as vacuum deposition or sputtering (see Patent Document 2), and the like are known. .

Then, by applying these methods, for example, by wet plating or dry plating, the key top is mirror-like, that is, a glossy metallic decoration is applied, and a colored transparent resin layer is formed on the surface of these layers. In order to meet the diversification of designs, a decorative layer with a color tone that should be called a color glossy metal tone is added to the glossy metal tone.
JP 2003-77358 A JP 07-245190 A

  However, it is difficult to obtain a mirror-like metallic tone by applying a paint containing metal powder, and in a method of decorating by dry plating or wet plating, a mirror-like metallic tone can be obtained. However, only a single color tone was obtained. Further, even when a colored transparent layer having various colors is further formed on the surface of the plating layer, only a color tone exhibiting a single color glossy metallic tone has been obtained.

  Accordingly, the present invention has been made for the purpose of obtaining a key top having novel visibility in order to realize a further improved design.

  The problem of diversification of the design is that not only the key top 2 constituting the appearance of the mobile phone 1 but also the logo type and model name of the company name are displayed and pasted to the casing as an exterior member of the electronic device. Various molded products that appear on the outside of the product and are subject to design, such as badge-shaped decorative resin molded products and resin casings that form the outer frame of electronic devices, that is, molding that requires decoration Since it is a problem that has also occurred on the body, in order to give further improved design, to obtain a molded body decorated with a novel visibility (hereinafter referred to as "decorated molded body") Is also intended.

  Therefore, the present invention is a decorative molded body in which a first metal layer is formed on the front surface side and a second metal layer is formed on the rear surface side of the transparent resin molded body, and the first metal layer is visible. The light reflectivity is 55% to 90%, the visible light reflectivity of the second metal layer is 55% to 100%, and includes the transparent resin molded body and is between the first metal layer and the second metal layer. The decorative molded body in which the layer thickness of the transparent layer formed on is 0.2 mm to 50 mm is provided.

  A decorative molded body in which a first metal layer is formed on the front surface side of a transparent resin molded body, and a second metal layer is formed on the rear surface side. The visible light reflectance of the first metal layer is 55%. -90%, the visible light reflectance of the second metal layer is 55% -100%, and is a transparent layer formed between the first metal layer and the second metal layer, including the transparent resin molding Since the thickness of the layer is 0.2 mm to 50 mm, light incident on the first metal layer from the outside passes through a transparent layer such as a resin molded body, and is between the first metal layer and the second metal layer. While repeating the reflection many times, a part of the light passes through the first metal layer and escapes to the outside. Therefore, it is possible to visually recognize a three-dimensional image in which a plurality of images having the same shape are overlapped in the depth direction in which the decorative molded body is visually recognized, such as an image reflected between mirrors placed facing each other. And the number of this image turns into an image rich in change which changes with the angle which visually recognizes a decorative molded object. Therefore, it becomes a decorative molded body that produces a three-dimensional and phantom image while using a glossy metallic tone with a mirror surface feeling, and a decorative molded body having novel visibility and excellent design can be obtained. Furthermore, this decorative molded body is applied to the resin molded body by making use of the thickness of the resin molded body itself by providing a first metal layer and a second metal layer on the front side and the back side of the resin molded body, respectively. Can be decorated. Therefore, it is possible to keep the thickness of the entire decorative molded body thin.

  Moreover, this invention is the 1st metal layer whose visible light reflectivity is 55%-90% from the side visually recognized, a transparent layer whose layer thickness is 0.2 mm-50 mm, and visible light reflectivity 55%-100%. A decorative molded body having a decorative layer laminated in the order of the second metal layer is provided.

  From the viewing side, the first metal layer having a visible light reflectance of 55% to 90%, the transparent layer having a layer thickness of 0.2 mm to 50 mm, and the second metal layer having a visible light reflectance of 55% to 100%. Since the molded body has decorative layers laminated in order, the light incident on the first metal layer from the outside passes through the transparent layer and is reflected many times between the first metal layer and the second metal layer. As a result, a part of the first metal layer passes through the first metal layer and escapes to the outside. Therefore, it is possible to visually recognize a three-dimensional image in which a plurality of images having the same shape are overlapped in the depth direction in which the decorative molded body is visually recognized, such as an image reflected between mirrors placed facing each other. And the number of this image turns into an image rich in change which changes with the angle which visually recognizes a decorative molded object. Therefore, it becomes a decorative molded body that produces a three-dimensional and phantom image while using a glossy metallic tone with a mirror surface feeling, and a decorative molded body having novel visibility and excellent design can be obtained. Furthermore, since this decorative molded body has a predetermined decorative layer in the molded body, by forming the decorative layer separately from the molded body, a novel decoration can be applied to various types of molded bodies. It can be applied easily and can be an inexpensive decorative molded body.

  And in this invention, a predetermined | prescribed decoration layer can be formed in the surface and the back surface of a molded object, and the inside depending on the case. Therefore, it is possible to freely select a place where the decorative layer is provided according to desired conditions such as manufacturing convenience and design requirements. Therefore, it is an easy-to-handle decorative molded body in which the use is not limited by limiting the location where the decorative layer is formed. However, when providing a decoration layer in the back surface and the inside of a molded object, since a decoration layer needs to be visually recognized through a molded object, it is necessary to use a highly transparent molded object. When the decorative layer is provided on the back surface or inside of the molded body, the first metal layer does not appear on the surface of the molded body, and there is no need to particularly provide a layer for protecting the first metal layer. preferable. In addition, when a decorative layer is provided on the surface of the molded body, the light reflected through the decorative layer can be directly viewed without passing through the molded body, so that the image can be clearly viewed without blurring. This is preferable in that various molded products can be used without being influenced by the material and color of the molded product with respect to the point and decoration.

  As a specific example of the molded body, the molded body can be a key top for a push button switch. If the molded body is used as a key top for a push button switch, it is possible to obtain a key top for a push button switch that produces a three-dimensional image while giving a glossy metallic tone with a mirror surface.

  Further, a transparent display portion representing characters and symbols and a transparent character display portion that represents characters and symbols in a letter-like shape and is different in color from the display portion are more visible than the second metal layer. Furthermore, it can be set as the decorative molded body currently formed.

  A transparent display part representing characters and symbols and a transparent character display part that represents characters and symbols in a letter-like shape and has a different color from the display part are further formed on the side that is visible from the second metal layer. Therefore, the light passing through the display portion with different colors and the extracted character display portion repeats reflection between the first metal layer and the second metal layer, while part of the light passes through the first metal layer and is externally transmitted. Therefore, it becomes a decorative molded body that can be visually recognized so that a plurality of images of the shape of the display section are continuous. Further, since the layer thickness of the display portion and the extracted character display portion can be increased, clear characters, symbols, and the like can be displayed. Here, “transparent” includes not only colorless and transparent but also colored and transparent. “Different colors” means that any one of hue, lightness, and saturation is different.

  According to the decorative molded body of the present invention, it is a decorative molded body with a completely new visibility that allows a stereoscopic image to be visually recognized based on a glossy metallic tone with a specular feeling, and there is a demand for a variety of designs. It can be particularly suitably used as a material for high personal use and as a finished product using the material.

  As an embodiment of the decorative molded body of the present invention, a key top used in a mobile phone 1 will be described with reference to the drawings. In the accompanying drawings, the thickness and length of the constituent material may not be based on the actual scale for convenience of explanation and easy viewing. In addition, the description common to the conventional technology, the configuration common to each embodiment (including the layer thickness), and the manufacturing method will be omitted.

First Embodiment FIG. 1 is an external plan view of a key sheet 11 as a cover member for a push button switch used in the cellular phone 1, FIG. 2 is a sectional view taken along line SA-SA in FIG. 3 is a partially enlarged plan view of the key sheet 11. The key sheet 11 is mainly made of resin, and displays a character, a symbol, etc., and a key top 12 that is pressed by a finger or the like, and a base sheet 13 that is made of a rubber-like elastic body such as silicone rubber are fixed by an adhesive 13a. It has a configuration. When the key top 11 is pressed with a finger on the key top 12, the base sheet 13 is elastically deformed, and a metal disc spring (not shown) disposed in the pressing operation direction is pressed to fix the fixed contact ( (Not shown) becomes conductive.

  The configuration of the key top 12 of the present invention that constitutes a part of the key sheet 11 will be described in further detail. The first metal layer 15 is formed on the surface 14a of the key top body 14 made of a transparent hard resin molded body, and the key top body. 14, the second metal layer 16 is provided on the back surface 14b. A decorative layer 17 is formed in a laminated structure including the first metal layer 15, the key top body 14, and the second metal layer 16. The first metal layer 15 is a layer that covers the surface 14 a of the key top body 14, but a portion where the first metal layer 15 is not formed is a display unit 18 that represents characters and symbols. Further, a protective layer 19 made of a transparent resin is formed on the upper layer of the first metal layer 15 to protect the first metal layer 15 from abrasion due to a pressing operation.

  The first metal layer 15 is a metal layer having a visible light reflectance of 55% to 90%, preferably 70% to 80%, and is formed by dry plating such as vacuum deposition, ion plating, sputtering, etc. A layer is preferred. The reason why the metal layer is preferably formed by dry plating is that in order to form a metal layer having a visible light reflectance of 55% to 90%, preferably 70% to 80%, the layer thickness is extremely thin. This is because it needs to be formed. The metal species contained in the first metal layer 15 can be, for example, gold, silver, copper, tin, iron, aluminum, chromium, titanium, magnesium, tungsten, cobalt, zinc, manganese, nickel, and the like. Use of aluminum is preferable in that the cost can be reduced. The reason why the visible light reflectance of the first metal layer 15 is 55% to 90%, preferably 70% to 80% is that if it is less than 55%, the reflected light is small and a glossy metallic tone with a specular feeling cannot be obtained. This is because if the ratio exceeds 90%, the transmitted light of the first metal layer 15 is small and it is difficult for the operator to visually recognize the image reflected on the second metal layer 16. Moreover, it is because a three-dimensional image is deeply and clearly expressed in the range of 70% to 80%.

  The second metal layer 16 is a metal layer having a visible light reflectance of 55% to 100%, preferably 85% or more. The second metal layer 16 is a dry plating such as vacuum deposition, ion plating or sputtering, or an electroless or electrolytic plating. It is a layer obtained by applying wet plating such as, or applying ink or paint containing metal powder. The metal species included in the second metal layer 16 can be the same metal as the metal that is to be included in the first metal layer 15. The reason why the visible light reflectance of the second metal layer 16 is 55% to 100%, preferably 80% or more is that if it is less than 55%, the reflected light is so small that an image cannot be projected. This is because the image is dark and clear in the above range.

  The key top body 14 is made of a thermoplastic resin such as polycarbonate or acrylic, a hard resin such as a thermosetting resin such as epoxy or silicone, or a rubber-like elastic body such as silicone rubber or thermoplastic elastomer in some cases. A molded body obtained by a method such as injection molding or casting. However, since these resins and the like constitute the decorative layer 17 together with the first metal layer 15 and the second metal layer 16, it is necessary to be a highly transparent material that efficiently transmits visible light. However, it is necessary to have a transparency of at least 70% in terms of visible light transmittance. The key top body 14 in the present embodiment is sandwiched between the first metal layer 15 and the second metal layer 16 and becomes a transparent layer to form a three-dimensional image. The distance from the layer 16 is preferably 0.2 mm to 50 mm, and more preferably 0.5 mm to 2.5 mm. The interval between the transparent layers between the first metal layer 15 and the second metal layer 16 may be 0.2 mm or more. However, the larger the interval, the stronger the light required to see the image, and the key top. Considering the case where it is used as 12, etc., 50 mm or less is preferable. Moreover, it is because a three-dimensional image cannot be visually recognized if this space | interval is less than 0.2 mm, and it is because a several stereoscopic image can be visually recognized more clearly in the range of 0.5 mm-2.5 mm.

  The decorative layer 17 forms the first metal layer 15 on the surface 14a of the key top body 14 formed in advance in a predetermined shape by dry plating or the like, while the second metal on the back surface 14b of the key top body 14 by dry plating or the like. It can be obtained by forming the layer 16. As another method, it is obtained by transferring to the front surface 14a and the back surface 14b of the key top body 14 using a transfer paper having a transfer layer in which the first metal layer 15 and the second metal layer 16 are sandwiched between resins. You can also. When the transfer paper is used as in another method, the transfer paper has a layer or an adhesive layer that protects the metal layer that becomes the first metal layer 15 and the second metal layer 16, and therefore the key top body 14 is moved to. After the transfer, the thickness of the transparent layer formed including the key top body 14 and these transparent layers is 0.2 mm to 50 mm between the first metal layer 15 and the second metal layer 16. It is preferable.

  The display unit 18 that displays characters, symbols, and the like is formed by not providing the first metal layer 15 on a part of the surface 14 a of the key top body 14. That is, a part of the first metal layer 15 provided on the surface 14a of the key top main body 14 may be removed by laser processing or etching processing, or the portion that becomes the display portion 18 is masked in advance and the portion. The first metal layer 15 may be provided except for. In this way, the portion where the first metal layer 15 is provided becomes the extracted character display portion 18a that extracts characters and symbols in the form of characters, and the portion where the first metal layer 15 is not provided indicates characters, symbols and the like. It becomes the display part 18 to represent. In the key top 12 shown in FIG. 3, a display portion 18 is formed in a “R” shape, and a first metal layer 15 is provided in a blank character display portion 18 a that forms the periphery of the “B” shape.

  The protective layer 19 is formed by applying a transparent resin on the first metal layer 15 of the key top 12. The protective layer 19 protects the first metal layer 15 and the display unit 18 formed on the surface 14 a of the key top body 14.

  The key sheet 11 can be obtained by fixing the key top 12 having the above configuration with the base sheet 13 and the adhesive 13a. For example, in the case of the key top 12 in which the “B” -shaped display portion 18 shown in FIG. 3 is formed, the entire key top 12 has a mirror-like luster and is based on a metal color, and a plurality of “B”. Images with overlapping character shapes can be visually recognized.

Second Embodiment : A key sheet 21 according to a second embodiment is shown in FIGS. In the key sheet 11 in the first embodiment, the portion where the first metal layer 15 is not provided and the decorative layer 17 is not formed becomes the display unit 18, but in the present embodiment, the first metal layer 15 is opposite to the display portion 18. A portion where the decorative layer 17 is provided is a display unit 28. The material used for the key sheet 21 can be the same material as that of the key sheet 11 shown in the first embodiment, and can be manufactured in the same manner as the key sheet 11.

  That is, in the key top 22 used for the key sheet 21 of the present embodiment, as shown in FIG. 5, for example, the first metal layer 15 is provided in a “◯” shape to form the display portion 28, and the first metal layer The blank character display part 28a is formed without providing 15. The key top 22 has a specular gloss as a whole, and can visually recognize an image in which a plurality of “◯” shapes are overlapped while being based on a metal color.

3rd Embodiment ; As shown in FIG. 6, the key top 32 used for the key sheet 31 shown in 3rd Embodiment is a transparent colored resin layer between the 1st metal layer 15 and the 2nd metal layer 16.

The key top body 14, the filling layer 34, and the transparent colored resin layer 33 form a transparent layer 35. The transparent layer 35, the first metal layer 15, and the second metal layer 16 form a decorative layer 37. Forming. The key sheet 31 is manufactured by coating the surface 14a of the transparent key top body 14 with the transparent colored ink to form the transparent colored resin layer 33 to be the character display portion 38a and coating the filling layer 34 thereon. And the 1st metal layer 15 is provided in the whole surface of the filling layer 34 with which the surface became smooth, and the protective layer 19 which consists of transparent resin is finally apply | coated and formed. On the other hand, the second metal layer 16 is formed on the back surface 14 b of the key top body 14. The material used for the key sheet 31 can be the same material as the key sheet 11 shown in the first embodiment.

  In the key sheet 31, unlike the key sheets 11 and 21 described above, the first metal layer 15 is formed on the entire surface of the filling layer 34, and the first metal layer 15 forms the display unit 38 or the blank character display unit 38 a. On the other hand, the colored resin layer 33 and the filling layer 34 form a display portion 38 and a blank character display portion 38a. Therefore, the layer thickness of the portion that becomes the display portion 38 can be increased. Accordingly, the boundary between the display unit 38 and the extracted character display unit 38a becomes clear, and clear characters, symbols, and the like can be displayed.

  According to this key sheet 31, the entire key top 32 is specularly glossy, and an image in which the shapes of the plurality of display portions 38 are overlapped can be visually recognized while being based on a metallic tone colored with the transparent colored resin layer 33. it can.

  Hereinafter, the present invention will be described in more detail based on examples and comparative examples.

  A sample serving as a key top, which is different from the key top (12) shown in the first embodiment in that the protective layer (19) is not provided, was manufactured. At this time, several different samples were manufactured by changing the thickness of the first metal layer (15), the transparent layer (key top body) (14), the second metal layer (16) and the value of the visible light reflectance. did. That is, the visible light reflectance of the first metal layer (15) is 50%, 55%, 65%, 75%, 85%, 90%, and the layer thickness of the transparent layer (15) is 0.1 mm, 0.2 mm. 0.5 mm, 2.5 mm, 10 mm, 50 mm, and the visible light reflectance of the second metal layer (16) of 50%, 55%, 65%, 75%, 85%, 95%, 100%, respectively. Samples with either value were produced. Tables 1 to 6 below show combinations of conditions of these samples and the state of images that can be visually recognized from the samples. Among these, the number of visible images shown in Tables 1 to 3, Table 5, and Table 6 and the clarity of the images are 30 cm from the sample at an angle of about 30 ° obliquely with respect to the horizontal surface of the key top (12) surface. It is a result when it is visually observed apart. In addition, the number of visible images shown in Table 4 is a result of visual observation at an angle of about 60 ° obliquely from the sample with respect to the horizontal surface of the key top (12) surface.

  Each of the above samples serving as examples and comparative examples was first subjected to masking printing in a “R” shape on one side (14a) of a resin molded body (14) made of a transparent polycarbonate resin having a predetermined layer thickness. Thereafter, aluminum was vapor-deposited by a vacuum vapor deposition method to form a first metal layer (15) to be a “B” -shaped extracted character display portion (18a). Next, a second metal layer (16) made of aluminum was formed on the entire other surface (14b) of the resin molded body (14) by vacuum deposition.

  The visible light reflectance is calculated from the following equation based on the visible light transmittance measured using an ultraviolet-visible spectrophotometer (“UV-1600” manufactured by Shimadzu Corporation) (visible light absorption). Ignore the rate).

  Visible light reflectance (%) = 100-Visible light transmittance (%)
