Description

  The present invention relates to a three-dimensional display body that three-dimensionally displays a predetermined display shape such as letters, numbers, symbols, figures, and patterns, and a background portion that is located around the display shape and that displays the display shape. Decorative decorations such as key tops for input switches equipped with this three-dimensional display, decorative sheets such as stickers and stickers, printed materials, etc. that have been decorated to display the display shape and background in three dimensions Regarding products.

  At least display shapes such as letters, numbers, symbols, figures and patterns are formed on a part of various members. For example, letters, numbers, and symbols are attached to the surface of keys such as a keyboard for inputting to a personal computer or a push button of a mobile phone, and in addition to characters on the surface of stickers, transfer sheets, stickers, labels, etc. Figures and patterns are shown.

Some of these products have been devised to display the display shape three-dimensionally as one of the design variations. There are various methods for displaying the display shape in three dimensions. For example, a key top for a push button switch used in a mobile phone uses a method of embedding characters and numbers in a three-dimensional shape inside a transparent key top. For example, it is described in Japanese Patent Application Laid-Open No. 2000-21259 (Patent Document 1), Japanese Patent Application Laid-Open No. 2002-23924 (Patent Document 2), Japanese Patent Application Laid-Open No. 2002-216572 (Patent Document 3), and the like. Also, there is a method in which a display shape is provided by printing on the top surface of a transparent resin key top, while the bottom surface of the resin key top is provided with a background color other than black having a reflectance of 0.3 or more to display the display shape in three dimensions. It describes in Unexamined-Japanese-Patent No. 2002-42598 (patent document 4).

  Embodiments of the present invention will be described below with reference to the drawings. In addition, in each embodiment, the same part attaches | subjects the same code | symbol and abbreviate | omits the description.

First Embodiment [FIGS. 1 to 7] ; In the first embodiment, a key top for a push button switch (hereinafter referred to as “key top”) 10 used in the mobile phone 1 shown in FIG. 1 is illustrated. As shown in FIGS. 2 and 3, the key top 10 is fixed to a base sheet 2 made of a rubber-like elastic body such as silicone rubber to form a push button switch key sheet 3. The key sheet 3 is a printed circuit board (FIG. (Not shown). FIG. 4 is a plan view of a plurality of key tops 10 and FIG. 5 is a cross-sectional view thereof.

  As shown in FIG. 4, the key top 10 as a decorative molded body includes a display portion 12 having a display shape of a number “1” on a surface 10 c of a key top body 10 a made of a transparent resin molded body, and the display The edge part 13 which covers the edge of the part 12, and the background part 14 which is located around the edge part 13 and expresses the numeral “1” appear. FIG. 5A shows a cross-sectional structure of the key top 10, and FIG. 5B shows an enlarged view of the region R1 in FIG. 5A. As shown in these drawings, the first layer 15 that forms the background portion 14, the second layer 16 that forms the border portion 13, and the grooves formed by the formation of the first layer 15 and the second layer 16 are filled. The third layer 17 that is solidly printed and the fourth layer 18 that is a glitter layer that makes the display unit 12 glitter are laminated on the bottom surface 10b of the key top body 10a to form the three-dimensional display body 11. In this specification, the “surface” means the surface on the side of the object to be observed that observes the display unit, and the “bottom surface” means the surface of the object to be observed on the side that observes the display unit. Means the opposite side.

  The key top body 10a is made of a hard resin such as polycarbonate, ABS resin, acrylic resin, polyester resin, epoxy resin, or silicone resin, or a rubber-like elastic body such as silicone rubber or thermoplastic elastomer, and is used for injection molding or casting. It is a molded object obtained by methods such as. However, these resins and the like need to be a highly transparent material that efficiently transmits visible light so that the three-dimensional display 11 provided on the bottom surface 10b of the key top body can be viewed from the surface 10c of the key top body 10a. is there. Therefore, a completely transparent material is preferable, but at least a visible light transmittance of 70% or more is required. It is a preferable aspect that the thickness of the key top body 10a is 0.2 mm to 1.0 mm.

  As shown in FIG. 6, the three-dimensional display 11 is formed by first drawing the first layer 15 serving as the background portion 14 on the bottom surface 10 b of the key top body by various printing methods such as silk printing or pad printing. Form. A variety of printing inks can be used, including those made of acrylic, vinyl, urethane, polyester, polycarbonate, etc., and those having a curing form such as a heat drying type, an ultraviolet curing type, and a heat drying type. Can be used. The background portion 14 uses ink of a different color from the display portion 12 so that the display portion 12 is conspicuous. In addition, the background portion 14 is preferably an ink having a high light-shielding property so as to make it difficult to visually recognize the glitter layer formed thereunder. The layer thickness of the first layer 15 is preferably 3 μm to 7 μm from the viewpoint that characters and the like are not crushed when forming a cut character.

  Similarly to the background portion 14, the second layer 16 serving as the border portion 13 can be printed by various printing methods using printing inks of various materials. Since the second layer 16 forms the border 13 that covers the edge of the display unit 12, the second layer 16 overlaps the first layer 15 and protrudes from the first layer 15 in the process of forming the second layer 16. Prints up to the edge of the paper. The rim portion 13 needs to have translucency so that the edge portion of the display portion 12 can be visually recognized through the rim portion 13, but the display portion 12 is difficult to see three-dimensionally when it is colorless and transparent. It is required that there is fogging to reduce Therefore, a cloudy resin ink in which a filler that reduces visible light transmittance is dispersed in a highly transparent resin binder is used. As the filler, a white pigment such as titanium white or iron oxide can be used, or a black pigment such as carbon black or aniline black can be used. A filler such as silica or talc can also be used. Among these fillers, white pigments and fillers such as silica and talc are preferred because they do not become dark, and white pigments are preferred because they can be whitish and give a more natural three-dimensional effect. It is preferable that 2.5 parts by weight to 25 parts by weight in the case of silica and 1 part by weight to 10 parts by weight in the case of a white pigment are included with respect to 100 parts by weight of the polymer in view of the display part 12 in three dimensions. In addition, it is a preferable aspect that the border part 13 has a color similar to that of the display part 12. This is because the border portion 13 looks like a shadow of the display portion 12 by using similar colors. Although the layer thickness of the second layer 16 varies depending on the visible light transmittance of the second layer 16, it is preferably 4 μm to 7 μm in order to make it appear three-dimensional.

  After the first layer 15 and the second layer 16 are laminated, the third layer 17 is formed by solid printing translucent ink on the entire bottom surface 10 b of the key top 10. Since the first layer 15 and the second layer 16 are printed and the ink is not formed on the central portion of the display unit 12 but is recessed, it is necessary to fill the recess and make it smooth. This is because it is difficult for the glittering film to be fixed even if the glittering film is fixed in the next step with the dent. Moreover, the reason why the translucent ink is used is that it is necessary to visually recognize the glittering film provided in the lower layer of the translucent ink. Therefore, the light-transmitting ink may be colorless and transparent, colored and transparent, or cloudy and transparent, as long as the fourth layer 18 can be seen through the third layer 17. The third layer 17 can also be formed by a printing method such as silk printing or pad printing. The layer thickness of the third layer 15 is sufficient if it is sufficient to fill the dent generated by the formation of the first layer 15 and the second layer 16 to reduce the level difference, and to make a gentle dent. It is preferable to do. Therefore, it can be set to 4 μm to 7 μm.

  The fourth layer 18 can be formed of a glitter film in which a metal vapor-deposited film is laminated with a resin film. Among them, a transfer sheet having an adhesive layer on the surface and capable of being transferred to a desired shape by thermal transfer or pressure transfer is used. It is preferable to use it. FIG. 7 schematically shows that unnecessary portions are removed after the glitter film is fixed to the third layer 17. By laminating the glitter film on the third layer 17, the display unit 12 exhibiting glitter is obtained by laminating the third layer 17 made of translucent ink and the fourth layer 18 made of glitter film. . In addition, it can be set as the display part 12 which has the color tone by the mixed food of the 3rd layer 17 and the 4th layer 18 by coloring the translucent ink which forms the 3rd layer 17. FIG. The fourth layer 18 having a layer thickness of 7 μm to 10 μm can be formed using a commercially available film having a layer thickness of about 20 μm to 35 μm including the release film.

  When the inside is visually observed from the surface 10c of the key top 10 thus obtained, the display shape of the number “1” formed as the display unit 12 can be viewed three-dimensionally.

Second Embodiment [FIGS. 8 to 10] ; The key top 20 described in this embodiment also has a plan view similar to FIG. 4 of the key top 10 shown in the first embodiment. However, the cross-sectional structure is different, as shown in FIG. In the key top 20, on the bottom surface 20b of the key top main body 20a made of a transparent resin molded body, a first layer 25 serving as an edge portion 23, a second layer 26 serving as a background portion 24, a first layer 25 and a second layer 26 are formed. The third layer 27 that is solid-printed with translucent ink so as to fill the grooves of the display portion 22 that represents the display shape of the number “1” in plan view generated by the formation of the first, and the display portion 22 that makes the display portion 22 shiny. Four layers 28 are laminated to form the three-dimensional display 21.

  The materials forming the first layer 25, the second layer 26, the third layer 27, and the fourth layer 28 are the second layer 16, the first layer 15, the third layer 17, and the fourth layer in the first embodiment. Each corresponds to the material used in No. 18. The layer thickness is also the same. Then, the three-dimensional display 21 is formed on the key top body 20a as shown in FIGS. 9 and 10, on the bottom surface 20b of the key top body 20a, the first layer 25, the second layer 26, and the third layer 27. Printing is performed in order, and finally, a glittering film to be the fourth layer 28 is attached, and an excess portion of the glittering film is removed.

  When the inside is visually observed from the surface 20c of the key top 20 obtained in this way, the number “1” formed as the display unit 22 can be seen in three dimensions.

Third Embodiment [FIGS. 11 and 12] ; The key top 30 described in this embodiment also has a plan view similar to FIG. 4 in the key top 10 shown in the first embodiment. However, the sectional structure is different as shown in FIG. The key top 30 is formed by forming the first layer 35 and the first layer 35 to be the edging portion 33 on the bottom surface 30b of the key top main body 30a made of a transparent resin molding, and the display shape of the number “1” in plan view. A second layer 36 printed with glitter ink so as to fill a groove in the central portion constituting the display portion 32, and a third layer 37 serving as a background portion 34 forming the periphery of the number “1”. Are stacked to form the three-dimensional display 31.

  That is, as shown in FIG. 12, the three-dimensional display 31 is formed on the key top body 30a by printing the first layer 35, the second layer 36, and the third layer 37 in this order on the bottom surface 30b of the key top body 30a. Do that. The first layer 35 is formed by printing the range from the periphery of the display unit 32 to the edge of the display unit 32. The same printing ink as that of the first layer 25 in the second embodiment can be used. The second layer 36 is formed by printing the display unit 32 while filling the recesses generated by the formation of the first layer 35. In this case, the first layer 35 and the second layer 36 overlap with each other at the edge portion 33. Since the second layer 36 is a glitter layer, glitter ink is used. Finally, the third layer 37 is formed by solid printing on the bottom surface 30 a of the key top 30 over the first layer 35 and the second layer 36.

  The materials forming the first layer 35 and the third layer 37 correspond to the materials used in the second layer 16 and the first layer 15 in the first embodiment, respectively. The layer thickness is the same. For the second layer 36, glitter ink such as silver ink or pearl ink is used. The glitter ink is an ink in which a glitter colorant composed of glitter particles is dispersed in a highly transparent binder. Examples of glittering coloring materials contained in glittering inks include metal powders such as aluminum and silver, those metals made into scales and scale foils, and pearl pigments with pearly luster using mica. It is done. When the scaly or scaly foil-like glittering particles are included, the glittering layer becomes excellent in light reflectivity, so that it is possible to obtain a product with excellent design that looks clearly three-dimensional. As the transparent binder, a transparent resin suitable for dispersing these glittering coloring materials is used. In order to produce a three-dimensional effect, the higher the light reflectance of the glitter ink, the more preferable, and the greater the content of glitter particles, the more preferable. However, when the content of the glittering particles in the solid content of the glittering ink is higher than 85 wt%, the film-forming property and adhesion of the glittering ink are deteriorated, and if the content is lower than 3 wt%, the stereoscopic effect cannot be obtained. More preferably, it is 3 wt%-85 wt%.

  Unlike the background portion 14 in the first embodiment and the background portion 24 in the second embodiment, the background portion 38 formed by printing the third layer 37 is a glitter layer (fourth layer) made of glitter ink or glitter film. Since it is not necessary to shield the layers 18, 28), a material having a high light-transmitting property can also be used. If a material with high translucency is used for the fourth layer 38, the illuminated key top 30 that illuminates the background portion 34 by an internal light source provided in the device can be obtained.

  When the inside is visually observed from the surface 30c of the key top 30 thus obtained, the display shape of the number “1” formed as the display portion 32 can be viewed three-dimensionally.

Fourth Embodiment [FIG. 13] ; The key top 40 shown in this embodiment is a glitter instead of the third layer 17 which is a translucent printing layer and the fourth layer 18 which is a glitter film in the first embodiment. The structure is the same as that of the key top 10 except that the third layer 47 is formed with a conductive ink. A cross-sectional view of the key top 40 is shown in FIG. The first layer 15 and the second layer 16 are the same as those in the first embodiment, and the glitter ink used in the third layer 47 is the same as the glitter ink used in the second layer 36 of the third embodiment. It is. Moreover, each layer thickness is also the same.

  When the inside is visually observed from the surface 40c of the key top 40 thus obtained, the display shape of the number “1” formed as the display unit 42 can be viewed three-dimensionally.

5th Embodiment [FIG. 14] ; The decorating sheet 50 shown by this embodiment has the structure which pinched | interposed the three-dimensional display body 11 shown by 1st Embodiment with the base film 50a and the transparent cover film 59. FIG. . A cross-sectional view thereof is shown in FIG. The decorative sheet 50 is manufactured on the bottom surface of the transparent resin film to be the cover film 59 by the first layer 15 to be the background portion 14, the second layer 16 to be the edging portion 13, and the like, as in the first embodiment. The third layer 17 that is solid-printed while filling the recesses formed by the formation of the first layer 15 and the second layer 16 and the fourth layer 18 made of a glitter film that makes the display section 52 glitter are laminated in this order. The three-dimensional display 11 is formed, and finally the base film 50a made of a resin film is fixed. The base film 50a can be fixed using an adhesive or thermocompression bonding.

  The base film 50a and the cover film 59 have materials, properties, and thicknesses selected depending on the intended use of the decorative sheet 50. For example, resin films such as polyurethane, polyester, nylon, PET, and polycarbonate are used. In particular, the cover film 59 is required to be a translucent film in order to make the display layer 52 visible.
