Japanese Patent Application No. 2004-088066

The same applies to the indicators and marks indicating the time characters provided on the display board of the portable watch, and the specification as a single decorative member is required, and the indicators and marks can have a three-dimensional effect or a metallic feeling. Has been done.

  Hereinafter, a conventional technique using a glass fiber cloth disclosed in the above-mentioned patent document in a display panel for a portable watch will be described with reference to FIGS. 7A and 7B are a plan view and a cross-sectional view of a conventional portable timepiece display panel. FIG. 7A is a plan view, and FIG. 7B is a cross-sectional view taken along line AA in FIG. Is shown. FIG. 8 shows an enlarged view of a portion B in FIG.

  The display board 10 shown in FIG. 7 is provided with a glass fiber cloth 3 knitted in a plain weave pattern in a recess 1b provided in the center of the display substrate 1 via an adhesive 5, and the glass fiber cloth. A logo mark (marked as ABCD in FIG. 7A) 7 is provided by printing on a surface having unevenness 3 through a base layer 6 made of a transparent resin. In addition, an indicator 2 having a time character is provided on the outer peripheral portion of the display substrate 1. The display board 1 is a display board provided with a small hole 1a for attaching a pointer at the center. This display board 10 uses a glass fiber cloth because it is desired to express the glittering gloss generated from the glass fiber cloth and the beautiful texture of the glass fiber cloth in the display board decorated with metal decoration.

  Here, the specification of each component which comprises the said display board 10 is as follows. The display substrate 1 is used by forming a substrate blank from phosphor bronze, white or brass plate or the like by press working, and performing surface treatment such as plating. In some cases, a fine concavo-convex pattern such as a satin finish or a basis weight is used. The central portion is provided with a concave portion 1b by cutting or the like, and the glass fiber cloth 3 is attached to the concave portion 1b. In addition, a small hole 1a for attaching the pointer is formed in the center by press working at the time of blank forming.

  As shown in FIG. 8, the glass fiber cloth 3 is bundled from several tens to several hundreds of glass fibers 3a having a thickness of about 5 μm as shown in a circled portion C, as shown in FIG. As shown, we use a knitted plain weave pattern. The glass fiber 3a has a diameter of about 0.4 [mu] m when it is thin, and when the diameter is about 4 to 6 [mu] m, the texture is clearly visible, so that the diameter is often used.

  The glass fiber cloth 3 has a transparent resin paint 3b close to the refractive index of the glass fiber 3a attached to the inside or the surface of the weave so as to prevent the glass fiber 3a from being loosened, and adjusts the texture while pulling from all sides. The resin cured under pressure and heating is used. And it affixes on the recessed part 1b of the display substrate 1 through the adhesive agent 5. FIG.

  The upper surface of the glass fiber cloth 3 forms an uneven surface 3c having very large unevenness. For this reason, the base layer 6 which comprises a flat surface is provided on the glass fiber cloth 3, and the logo mark 7 is printed on it. The pedestal layer 6 is overprinted using a transparent resin, formed thick and has a flat surface. The logo mark 7 is formed by a printing method such as a pad printing method using black ink or the like.

  For the index 2 which is a time character, a metal index formed by an electroforming plating method or the like is attached to a predetermined position on the outer peripheral portion of the display substrate 1 via an adhesive. Further, depending on the specifications, a metal indicator with a foot is attached by a caulking method, or an indicator is formed by a printing method using ink.

  The display board 10 is formed using the components having the specifications as described above. Depending on the specifications, there is also a display board in which a glass fiber cloth is provided on the entire surface of the display substrate.

  The glass fiber cloth has very large irregularities on its surface. In the case of providing an index or the like on a surface having large irregularities, a pedestal layer is provided thereon to form a flat surface, and the index is provided on the flat surface. However, such a configuration has the following problems.

  (1) The pedestal layer is dyed in a color tone such as an index or a mark, and the outline of the index or the mark does not appear clearly. The pedestal layer functions like a light guide plate. Reflected light and transmitted light from the indicators and marks formed by printing enter the pedestal layer and are guided, and the color of the indicators and marks appears throughout the pedestal layer. . In particular, the color tone appears darkly around the indicators and marks. This phenomenon appears remarkably when the pedestal layer is transparent, and this tendency appears if the colored pedestal layer has transparency. For this reason, the outline of the index or mark does not appear clearly, and the appearance quality of the index or mark is impaired.

  (2) The pedestal layer is formed thick by overprinting in order to erase the unevenness. For this reason, undulation undulation occurs on the surface of the pedestal layer, and the undulation also appears on the surface of the mark or mark formed by printing, the color luster changes depending on the viewing direction, and the mark or mark is not clearly visible. In some cases, the index or mark may be cut.

  The present invention has been made in view of the above-mentioned problems. The object of the present invention is an index or mark that has a clear outline and looks beautiful, has no undulations on the surface, and has no change in color. It is to obtain a decorative member.

As a means for solving the problems, the display board according to the present invention is characterized in that in the display board in which the decorative member is provided on the base layer provided on the cloth or the substrate having the uneven surface, the base layer is formed of the same printing plate. The three resin layers consist of a lowermost guide layer formed to prevent the ink from flowing out when the middle flat layer is printed, and the pedestal layer as a flat surface. In order to finish, a middle plane layer formed by printing using a low viscosity ink of 100 poise or less and a top surface layer formed to match the color tone of the fabric or substrate It is what.

The display board of the present invention is characterized in that the decorative member has a textured or textured substrate or a base layer of the same color or white as the substrate, and a finishing layer formed on the base layer with the same printing plate as the base layer. It is characterized by comprising.

The display panel of the present invention is characterized in that the pedestal layer is provided on the uneven surface of the display substrate.

The display panel of the present invention is characterized in that the uneven surface of the display substrate has an uneven step of 25 μm or more.

Further, the display board of the present invention is characterized in that the fabric or substrate having the uneven surface is a display substrate provided with an uneven pattern pattern, or a display substrate to which a glass fiber cloth or a morpho fiber cloth is attached. To do.

The display board of the present invention is characterized in that the cloth or the substrate having the uneven surface is a transmissive substrate.

The display board according to the present invention is characterized in that the transparent substrate is made of at least one of resin, glass, and ceramic.

In addition, the manufacturing method of the display panel of the present invention is characterized in that a guide layer, a transparent flat layer, and a surface layer are sequentially formed on the concavo-convex surface on the display substrate having the concavo-convex surface by three layers. Forming a base layer composed of a resin layer, and forming a decorative member composed of two layers by sequentially forming a base layer and a finishing layer partially on the upper surface of the base layer with the same printing plate. It is characterized by.

Moreover, the manufacturing method of the display panel of the present invention is characterized in that the planar layer is formed by printing with a UV curable resin.

  As an effect of the invention, the decorative member of the present invention is composed of a base layer of the same color or white as the substrate and a finishing layer formed of the same printing plate as the printing plate of the base layer. Although the finishing layer has a color tone as a decorative member, the finishing layer has the same shape and the same size on the base layer because it is printed on the same printing plate. Therefore, the underlayer cannot be seen from the finish layer. In addition, the light transmitted through the finishing layer due to the presence of the underlayer is reflected by the underlayer, or absorbed or regulated by the underlayer and out of the underlayer (to the lower surface side of the underlayer or around the underlayer) Less light penetration (outgoing). For this reason, the phenomenon in which the color tone of the finishing layer, that is, the color tone of the decorative member bleeds into the members around the decorative member is suppressed to a small level. And the outline of a decoration member becomes clear and is visually recognized. In addition, the decorative member is brightened and visually recognized by reflection from the base layer.

  Further, the decorative member composed of the base layer and the finish layer is partially provided on the flat surface of the pedestal layer having a flat surface. When a decorative member is formed on a flat surface by a printing method, the surface of the decorative member can be obtained as a smooth and clean surface free from undulations and undulations. And the beautiful color of the decorative member is visually recognized from any direction. The pedestal layer is composed of three resin layers formed of the same printing plate, and a guide layer is provided at the bottom, a transparent flat layer at the center, and a surface layer at the top. The guide layer is provided to prevent the ink from flowing out so that printing can be performed along the shape of the guide layer when the flat layer is printed. The flat layer is provided in order to flatten the printing upper surface. The surface layer is provided for color and color matching of the substrate on which the pedestal layer is provided. Thereby, a flat surface is formed on the upper surface of the base layer having the same color tone as the substrate. Therefore, the surface of the decorative member provided thereon is finished cleanly.

  Here, the planar layer is formed of a UV curable resin. In addition, the viscosity of the ink generated from the UV curable resin is 100 poise or less. Since the viscosity of the ink is low, the flow of ink during printing and after printing is improved, and a flat surface is likely to appear. Moreover, it can harden | cure in the state which ensured the flat surface, without destroying a shape by carrying out UV hardening using UV hardening resin. In addition, since the guide layer is provided under the flat layer, the ink does not flow out of the guide layer during printing.

  When the decorative member composed of the pedestal layer, the base layer, and the finish layer is provided on the uneven surface, the effect is extremely exhibited. If a pedestal layer having the above specifications is provided on the uneven surface, the pedestal layer can be finished to a clean flat surface. In addition, the effect is sufficiently exerted on the uneven surface having the uneven step of 25 μm or more. With a concavo-convex surface smaller than 25 μm, a flat surface can be obtained with one resin layer, and there is no need to provide two layers.

  In such a display board in which a decorative member composed of a pedestal layer, a base layer, and a finishing layer is provided on a display substrate having an uneven surface, the outline of the decorative member can be seen clearly. Further, the color of the decorative member can be clearly distinguished from the colors of the surrounding display boards, and the decorative property of the decorative member is enhanced. Moreover, a feeling of build-up appears there depending on the thickness coming from the pedestal layer consisting of three layers and the decorative member consisting of two layers, and a three-dimensional effect appears on the decorative member.

  In addition, if the display substrate is a display substrate provided with an uneven pattern pattern, or a display substrate with a glass fiber cloth or morpho fiber cloth attached, the effect of the pedestal layer appears remarkably, and the decorative member appears while a beautiful pattern or color appears. A smooth and glossy color is obtained.

  Further, when a transmissive substrate is used as the display substrate, the display plate can be made transmissive, and a solar cell can be provided on the lower surface of the display plate so that it can be used as a display plate for a portable timepiece with solar cell. Similarly, an EL (electroluminescence) can be provided on the lower surface of the display plate and used as an EL display plate.

  In addition, when resin (plastic), glass, ceramic, or the like is used as the material of the transmissive substrate, the display plate can be manufactured at a low manufacturing cost because the material cost is low.

Moreover, the manufacturing method of the display board of this invention is the same printing plate on the uneven surface on a display substrate which has an uneven surface, The base layer which consists of a resin layer of 3 layers of a guide layer, a transparent plane layer, and a surface layer is provided. Print form. Then, a manufacturing method is employed in which a decorative member composed of a base layer and a finishing layer is formed by printing on the upper surface of the pedestal layer partially with the same printing plate. When the three layers of the guide layer, the planar layer, and the surface layer that are the pedestal layers are formed on the same printing plate, the three layers can be formed by laminating with the same shape and size. Among them, a flat surface is obtained by printing and forming the flat layer using a UV curable resin ink having a viscosity of 100 poise or less, and performing a curing treatment by ultraviolet irradiation. Moreover, it can harden | cure without destroying the shape of the flat surface. Thereby, a flat surface is obtained in the pedestal layer. And the beautiful printing surface without a wave | undulation etc. is obtained in the decorative member formed by printing on it. Further, when the foundation layer and the finishing layer serving as the decorative member are printed and formed with the same printing plate, the foundation layer and the finishing layer can be formed by being laminated in the same shape and the same size. As a result, since the finishing layer does not directly contact the pedestal layer, the color tone of the finishing layer that makes the color tone as a decorative member is not widely transmitted to the pedestal layer, and the phenomenon in which the color tone of the finishing layer appears blurred to the pedestal layer is eliminated. .

  The surface layer of the pedestal layer is preferably formed in the same color or transparent color as the display substrate or the reflective layer provided on the lower surface side of the display substrate. If formed in a similar color, the color tone of the substrate and the color tone of the reflective layer can be harmonized, and the pedestal layer does not feel uncomfortable. Even if the color tone of the decorative member, that is, the phenomenon that the color tone of the finishing layer constituting the decorative member bleeds into the pedestal layer, the color tone becomes almost inconspicuous.

  The best mode for carrying out the present invention will be described below with reference to FIGS. FIG. 1 shows a cross-sectional view of a main part of a decorative part according to an embodiment of the present invention. FIG. 2 is an explanatory view for explaining the operation of the decorative part in FIG. 1 and shows an enlarged main part.

  In FIG. 1, reference numeral 27 denotes a decorative member, and indices, symbols such as numbers and letters, marks, concavo-convex patterns, and the like are listed as objects of the decorative member. The decorative member 27 includes a base layer 25 and a finishing layer 26 provided on the base layer 25. The underlayer 25 and the finishing layer 26 are formed by a printing method using the same printing plate made of resin. As the resin, resins such as urethane resin, acrylic resin, and epoxy resin are used. In addition, as a printing method of the base layer 25 and the finishing layer 26, a known printing method such as screen printing or pad printing is used. Since they are formed with the same printing plate, they are finished in the same shape and size. The finishing layer 26 has a color as a decorative member, and is formed with a color tone required for the decorative member. Therefore, the required color tone is obtained by mixing pigment, metal powder, or the like in the resin. The undercoat layer 25 is preferably finished in a white color tone or a color tone similar to the color of the fabric or substrate having an uneven surface described later. When the foundation layer 25 is white, the color of the finish layer is visually recognized. In addition, if the color tone is similar to the color of the fabric or substrate having an uneven surface, the underlying layer is not noticeable.

  Reference numeral 24 denotes a pedestal layer. The pedestal layer 24 is provided to ensure a flat surface for forming the decorative member 27. The pedestal layer 24 is constituted by three layers of a lowermost guide layer 21, a middle plane layer 22, and an uppermost surface layer 23. Since all are formed by the printing method using the same printing plate, they are finished in the same shape and size.

  The lowermost guide layer 21 is provided so that a flat layer to be printed thereon forms a flat surface and forms a desired shape. The guide layer 21 is provided within a thickness range of 10 to 30 μm, but may be adjusted according to the size of the unevenness of the fabric or the substrate described later. If the level difference is large, it is formed thick, and if the level difference is small, it may be thin. Moreover, it is preferable that the color tone of the guide layer 21 is finished to a color tone that is similar to or transparent to the color of the fabric or substrate having an uneven surface, which will be described later. The guide layer 21 is formed by a printing method such as a screen printing method using an ink of a thermosetting resin such as a urethane resin, an acrylic resin, or an epoxy resin, and is finished by performing a curing process by heating.

  The middle plane layer 22 is formed to finish the pedestal layer 24 to a flat surface. A transparent UV curable resin ink is used, the viscosity is set to a low viscosity of 100 poises or less, and the flowability of the ink is improved to form by a printing method such as screen printing. Printing is performed using the same printing method as that for the guide layer 21, and the printing plate is also formed using the printing plate of the guide layer 21. When printing is performed using the ink having the above viscosity, the flat layer is formed on the guide layer 21 in a short time without protruding from the shape of the guide layer 21 and flowing out of the shape. After the formation, ultraviolet ray irradiation is performed to perform a curing process. When the UV curing treatment is performed, the flat surface is not deformed and is cured while maintaining the flat surface.

  The uppermost surface layer 23 is provided in order to match the surface state of a cloth or substrate having an uneven surface, which will be described later. Therefore, it is made to finish in the same color or transparent color as the fabric or the substrate. The surface layer 23 uses the same printing method as the guide layer 21 and the planar layer 22, and the printing plate is also formed using the printing plate of the guide layer 21 and the planar layer 22. Further, since the surface layer 23 is provided in a state in which the flat surface obtained by the planar layer 22 is maintained, the surface layer 23 is preferably formed within a range of 5 to 20 μm. It is formed using resin ink such as urethane resin, acrylic resin, or epoxy resin.

  The pedestal layer 24 having the above configuration is finished on a completely flat surface free from printing undulations and undulations. Then, when the decorative member 27 is partially provided on the flat surface by a printing method, the surface of the decorative member 27 can be obtained as a smooth and smooth surface free from undulations and undulations. And the same color is visually recognized from any direction.

  Next, in the present embodiment, reference numeral 13 denotes a glass fiber cloth having surface irregularities, which is a fabric of the pedestal layer 24. The glass fiber cloth 13 is formed by bundling several tens to several hundreds of glass fibers 13a having a thickness of about 5 μm and knitting into a plain weave pattern as described in the prior art. The glass fiber 13a has a thickness of about 0.4 [mu] m when it is thin, and when a diameter of about 4 to 6 [mu] m is used, the texture can be clearly seen, so that the decorativeness as a glass fiber cloth is enhanced.

  The glass fiber cloth 13 has a transparent resin paint 13b having a refractive index close to the refractive index of the glass fiber 13a attached to the inside or the surface of the weave so that the texture is adjusted while pulling from all sides. The resin cured under pressure and heating is used. The glass fiber cloth 13 is formed by first immersing the glass fiber cloth in a resin coating solution. This resin coating liquid is a coating liquid produced by mixing a resin with a solvent such as thinner, and the blending ratio (% by weight) is approximately the ratio of resin 1: solvent 10. This blending ratio is very low in resin content, and the resin penetrates sufficiently into the fabric of the glass fiber cloth (texture or gaps between the bundled glass fibers), and the amount of resin adhering to the glass fiber To make it less. This is because the feeling of glitter is impaired when the amount of resin adhering to the surface of the glass fiber is large. After being immersed for about 1 to 3 minutes, the glass fiber cloth coated with the resin is taken out and dried at a low temperature of 60 ° C. or lower. This is performed in order to temporarily cure the resin by low-temperature drying so as to eliminate the sticky state of the resin and facilitate handling, and may be naturally dried. Next, the glass fiber cloth in which the resin is temporarily cured is sandwiched between two flat silicon rubber plates, and pressed while being heated at a temperature of 90 ° C. or higher. At this time, the glass fiber cloth is pulled slightly from the four corners, and is made to be in a tensioned state so that the cloth is neatly arranged. The resin is re-dissolved by heating at this time, sufficiently penetrates into the fabric, and hardens. By taking such a process, the resin coating 13b penetrates into every corner of the cloth and covers the glass fiber, and a flat glass fiber cloth 13 with a beautifully shaped cloth is obtained. The glass fiber cloth formed in this way appears flat at first glance, but the knitted joints are considerably uneven, and the surface forms a stepped uneven surface 13c close to 50 to 100 μm.

Reference numeral 11 denotes a substrate. In the present embodiment, a metal plate is used as a substrate to which the glass fiber cloth 13 is attached. The substrate 11 is not limited to metal, and other materials such as resin, ceramic, glass, wood, and stone can be used. It selects suitably according to the specification of a display board. And the glass fiber cloth 13 is affixed on the surface of the board | substrate 11 through the adhesive agent 15. FIG.

  In the configuration of the decorative member of the present embodiment, a glass fiber cloth 13 is provided on a metal substrate 11. A pedestal layer 24 including three layers of a guide layer 21, a planar layer 22, and a surface layer 23 is provided on the uneven surface 13 c of the glass fiber cloth 13, and the base layer 25 and the finishing layer 26 are formed on the pedestal layer 24. The configuration in which the decorative member 27 is provided is taken. In other words, the decorative member 27 is provided in the specification that uses the glass fiber cloth 13 to give a sparkle to enhance the decorativeness. Here, since the glass fiber cloth 13 is used for the cloth, the guide layer 21, the surface layer 23, and the base layer 25 are formed of a transparent resin so as not to impair the glittering feeling emitted from the glass fiber cloth 13. .

  Next, the operation and effect of the decorative member 27 having the above configuration will be described with reference to FIG. In FIG. 2, a decorative member 27 formed by laminating a base layer 25 and a finishing layer 26 is provided, and a pedestal layer 24 formed of a surface layer 23, a flat layer 22 and the like is provided thereunder. . L 1, L 2, and L 3 indicate paths of light incident on the decorative member 27.

  Here, when the finishing layer 26 of the decorative member 27 has no transparency, the light L1 incident on the upper surface 26a of the finishing layer 26 is reflected by the upper surface 26a of the finishing layer 26. And the shape and color tone are visually recognized by the reflected light of the finishing layer 26. Although not shown, light absorbed by the finishing layer 26 is also generated. Next, when the finish layer 26 has transparency and reflectivity, and the base layer does not have transparency, the light L2 incident on the top surface 26a of the finish layer 26 is reflected by the top surface 26a of the finish layer 26. Light and light reflected by the upper surface 25a of the underlayer 25 are generated. And the color tone of the finishing layer 26 is visually recognized by those reflected lights. Light absorbed by the finishing layer 26 and the underlayer 25 is also generated, but this is not shown. In the case described above, it is preferable to tailor the base layer 25 to a white color tone. When tailored to a white color, brightness appears in the color tone of the finished layer, and vividness appears. In the case of the above two cases, since there is no light that directly enters the pedestal layer 24 from the base layer 25, the pedestal layer 24 is not dyed by the color tone of the finishing layer 26 or the color tone of the base layer 25. Although not shown, some of the reflected light from the side surface 26b of the finishing layer 26 and the side surface 25b of the underlayer 25 enters the pedestal layer 24, but the side surface 26b of the finishing layer 26 and the underlayer Since the side surface 25b of 25 has a small area, the amount of light entering the pedestal layer 24 is very small. For this reason, the degree to which the pedestal layer 24 is dyed with the color tone of the finishing layer 26 and the color tone of the underlayer 25 is small and hardly visible.

  Next, when the finishing layer 26 and the base layer 25 have transparency and reflectivity, the light L3 incident on the top surface 26a of the finishing layer 26 is reflected by the light reflected by the top surface 26a of the finishing layer 26 and the base layer 25. The light reflected by the upper surface 25a and the light transmitted through the base layer 25 are generated. The light that is transmitted through the base layer 25 and is incident on the side surface 25b of the base layer 25 is reflected by the side surface 25b, and the reflected light changes its traveling direction toward the inside, passes through the base layer 25, and enters the pedestal layer 24. Proceed toward. Further, when light transmitted through the finishing layer 26 passes through the base layer 25 and enters the pedestal layer 24, wavelength conversion is performed, and light having the color tone of the base layer 25 enters the pedestal layer 24. For example, when the base layer 25 is formed in white, light having a white wavelength enters the pedestal layer 24. As described above, when the finishing layer 26 and the underlayer 25 have transparency and reflectivity, the area of the light incident on the pedestal layer 24 is limited by the influence of the side surface 25b of the underlayer 25, and the pedestal is limited. Does not spread widely in layers. For this reason, the base layer 24 around the decorative member 27 is not strongly dyed by the color tone of the finishing layer 26. Furthermore, since the light incident on the pedestal layer 24 is converted into light having the wavelength of the color of the base layer 25, the color tone of the finishing layer 26 does not appear. As a result, the pedestal layer 24 around the decorative member 27 is less affected by the color tone of the decorative member 27, and the contrast between the color tone of the pedestal layer 24 and the decorative member 27 is increased. The outline is clearly and clearly visible.

  In the present embodiment, a transparent guide layer 21, a transparent plane layer 22, and a transparent surface layer 23 are laminated on the uneven surface 13 c of the glass fiber cloth 13 so as not to impair the glittering feeling generated by the glass fiber cloth 13. A pedestal layer 24 is formed, and a decorative layer 27 is formed by laminating a white base layer 25 and a finish layer 26 having a color tone as a decorative member on a part of a flat surface of the pedestal layer 24. The pedestal layer 24 around the decorative member 27 can be visually recognized from the upper surface of the pedestal layer 24 with the glittering feeling of the glass fiber cloth 13 without being strongly dyed by the color tone of the decorative member 27 due to the operation described above. Is done. On the other hand, from the decorative member 27, the color of the bright decorative member 27 is visually recognized with a clear outline.

  In addition, the pedestal layer 24 provided with the flat layer 22 is formed on the concavo-convex surface of the rugged glass fiber cloth 13 with a UV-curable resin ink having a low viscosity, so that the upper surface of the pedestal layer 24 is formed on a flat surface. In addition, since the decorative member 27 is formed on the flat surface, the surface of the decorative member 27 can be obtained a smooth and smooth surface free of undulations and undulations. And the same color is visually recognized from any direction.

  Next, a method for manufacturing a decorative member having the above configuration will be described. First, the guide layer 21 is printed and formed by a screen printing method on a concavo-convex surface 13c of the glass fiber cloth 13 affixed to the substrate 11 with an adhesive 15 using a screen printer. In the present embodiment, the printing ink to be used is formed using a resin ink such as a transparent urethane resin, epoxy resin, or acrylic resin. In addition, the required thickness is ensured by performing two or three overprints as necessary. After printing, it is cured by heating and drying at 80 ° to 140 °. Next, the planar layer 22 is printed and formed on the guide layer 21 by the same printing method as the guide layer 21 using the printing plate on which the guide layer 21 is printed. The printing ink used is an ink produced by dissolving a transparent UV curable resin in a solvent such as acetone to have a viscosity of 100 poise or less. Since the viscosity of the ink is low, the flowability is good, and the flat planar layer 22 is formed by one printing. After printing, the planar layer 22 is cured by irradiating with ultraviolet rays. As the UV curable resin, there are epoxy resin, acrylic resin, etc., and those resins are used. Next, the surface layer 23 is printed on the planar layer 22 by the same printing method as that for the planar layer 22 using a printing plate on which the planar layer 22 is printed. In this embodiment, it is formed to a required thickness using a resin ink such as a transparent urethane resin, epoxy resin, or acrylic resin. After printing, it is cured by heating and drying at 80 ° to 140 °. Through the above manufacturing steps, a pedestal layer 24 in which three layers of the guide layer 21, the planar layer 22, and the surface layer 23 are laminated is obtained. A flat surface is formed on the upper surface of the base layer 24.

  Next, the base layer 25 is partially printed on the flat surface of the pedestal layer 24 by a screen printing method using a screen printer to a required thickness. In this embodiment, the printing ink to be used is formed using resin ink such as urethane resin, epoxy resin, acrylic resin having a color tone similar to that of white or glass fiber cloth. After printing, it is cured by heating and drying at 80 to 140 °. Next, the finishing layer 26 is printed and formed on the underlayer 25 by the same printing method as the underlayer 25 using the printing plate on which the underlayer 25 is printed. The printing ink to be used is formed by using a colored resin ink such as urethane resin, epoxy resin, acrylic resin or the like that is colored in a required color. After printing, it is cured by heating and drying at 80 ° to 140 °. The decorative member 27 in which the base layer 25 and the finishing layer 26 are laminated is obtained through the above manufacturing steps.

  In the present embodiment, the pedestal layer 24 is provided on the glass fiber cloth 13 that forms the uneven surface, and the decorative member 27 is provided on the pedestal layer 24. However, it is limited to the glass fiber cloth that has an uneven surface. The same effect can be obtained by using a substrate on which a morpho fiber cloth or other fiber cloth is attached, a resin substrate provided with an uneven pattern, a ceramic substrate, a glass substrate, a metal substrate, or the like.

  In addition, the configuration of the decorative member of the present invention has a remarkable effect when the uneven step has a thickness of 25 μm or more. If the step is smaller than 25 μm, it is possible to obtain a flat surface by adjusting the viscosity etc. with one pedestal layer, but if it is larger than 25 μm, it becomes a surface of undulation or undulation and a flat surface cannot be obtained. . When the pedestal layer having the three-layer structure of the present invention is used, a flat surface can be formed even with unevenness having a considerably large step.

  In the present embodiment, the base layer 25 constituting the decorative member 27 is white or similar in color to the glass fiber cloth, and the guide layer 21 and the surface layer 23 constituting the pedestal layer 24 are formed of a transparent resin. This layer may be appropriately selected according to the color tone of the substrate and the color tone of the fiber cloth.

  Hereinafter, the decorative member and the display panel of the present invention will be described in more detail while giving examples. First, a decorative member and a display board according to Example 1 will be described with reference to FIGS. Here, FIG. 3 shows a plan view and a cross-sectional view of the timepiece display plate according to the first embodiment of the present invention. FIG. 3 (a) is a plan view, and FIG. The AA sectional view of a) is shown. FIG. 4 shows an enlarged view of a portion B in FIG. In FIG. 3A, the lattice-like pattern is omitted and only a part is drawn.

  In FIG. 3, the timepiece display plate 30 includes a transparent display substrate 31 having a lattice-patterned uneven surface 31 c on the entire surface, a transflective film 32 disposed on the lower surface of the display substrate 31, and the display substrate 31. A pedestal layer 44 provided at a predetermined position on the concavo-convex surface 31c, a logo mark 47 provided on the flat surface of the pedestal layer 44 (in FIG. 3A, the letters ABCD are shown), and The display board 31 includes twelve pedestal layers 54 provided at predetermined positions on the uneven surface 31 c in the outer peripheral area of the display substrate 31, and an index 57 as a time character provided on the flat surface of the twelve pedestal layers 54. And although not shown in figure, a solar cell is arrange | positioned by the lower surface side of this display board 30, and it is used as a display board for solar cells.

  Here, the display substrate 31 is made of a transparent polycarbonate resin, and has a small hole for attaching a pointer at the center and an uneven surface 31c on the entire upper surface side. The uneven surface 31c on the upper surface is provided in a lattice pattern, and the uneven step has a step of about 50 to 60 μm. The display substrate 31 is formed by an injection molding method, and the uneven surface 31c on the upper surface is formed by transferring from a mold.

  The transflective film 32 is a film having both transmissive and reflective functions. In Example 1, a white ink is produced by blending 5% by weight of a white pigment in a transparent urethane resin, This is a transflective film that is formed by screen printing to a thickness of about 10 μm and has a transmittance of about 50%. The transflective film 32 and the transparent display substrate 31 on the translucent reflective film 32 ensure a transmittance of about 40% and drive the solar cell. Moreover, the display substrate 31 is visually recognized with a fairly strong white color tone by making the transflective film 32 white.

  As shown in FIG. 4, the pedestal layer 44 is formed by stacking three layers of a lowermost guide layer 41, a middle plane layer 42, and an uppermost surface layer 43. In any case, the same printing plate is used for printing by the screen printing method, and the printing-curing process is sequentially repeated and laminated. Therefore, the guide layer 41, the flat layer 42, and the surface layer 43 that constitute the pedestal layer 44 have the same shape and the same size.

  The guide layer 41 in Example 1 is formed of a thermosetting transparent urethane resin. Overprinting is performed twice using a transparent urethane resin ink to form a thickness of about 20 μm, followed by a heat treatment at 80 ° to 140 ° C. for 60 to 90 minutes to perform a curing treatment. .

  In addition, the planar layer 42 in Example 1 is formed of a transparent UV curable acrylic resin. Printing is performed using an ink in which an acrylic resin is dissolved in a solvent such as acetone to have a viscosity of 100 poise or less. When printing with ink of 100 poise or less, a flat layer having a flat surface can be obtained in a short time without protruding from the guide layer 41. After printing, the resin is cured by irradiating with ultraviolet rays.

  The surface layer 43 in Example 1 is the same ink as the printing ink used in the transflective film 32, that is, a white ink is mixed with 5% by weight of a white pigment in a transparent urethane resin. The thickness is about 10 μm. After printing, the heat treatment is performed at 80 ° to 140 ° C. for 60 to 90 minutes. In the pedestal layer 44 configured as described above, the flat surface obtained by the flat surface 42 is maintained as it is, and a flat surface is formed on the upper surface of the pedestal layer 44. And since the surface layer 43 on the top is formed with the same white ink as the transflective film 32, the base layer 44 is hardly conspicuous in the white display board.

  Next, as shown in FIG. 4, the logo mark 47 includes a base layer 45 and a finish layer 46 provided on the base layer 45. In any case, the same printing plate is used for printing by the screen printing method, and the printing-curing process is sequentially repeated and laminated. Therefore, the base layer 45 and the finishing layer 46 have the same shape and size.

  Here, the base layer 45 in Example 1 is formed to have a thickness of about 20 μm by performing two times of overlapping printing using the same white ink as the printing ink used in the transflective film 32. Since the thickness is thick, the transmittance is only about 20%, and much light is reflected. After printing, the heat treatment is performed at 80 ° to 140 ° C. for 60 to 90 minutes. In addition, the finishing layer 46 in Example 1 is formed to a thickness of about 20 μm by performing two times of overprinting using an ink in which a black pigment is blended in a thermosetting urethane resin by 15% by weight. The transmittance of the finishing layer 46 is almost zero. After printing, the heat treatment is performed at 80 ° to 140 ° C. for 60 to 90 minutes.

  Next, the index 57 and the pedestal layer 54 provided thereunder have the same configuration as the logo mark 47 and the pedestal layer 44. The pedestal layer 54 and the index 57 are formed by simultaneously printing in the printing process for forming the pedestal layer 44 and the logo mark 47. Accordingly, the ink and thickness used are the same as those of the base layer 44 and the logo mark 47.

  In the display board 30 having the above configuration, the logo mark 47 and the index 57 are formed on a pedestal layer having a flat surface, and a base layer is provided. The color tone of the mark 47 and the index 57 is not transferred to the pedestal layer, and the logo mark and index with a clear outline are visually recognized. The logo mark 47 and the index 57 have a thickness of about 40 μm and are formed by printing, so that their surfaces are smooth and round. For this reason, it is visually recognized with a three-dimensional effect. Further, since the entire display panel is finished in white tone, the logo mark 47 and the index 57 finished in black are clearly visible. Furthermore, the lattice-shaped uneven pattern pattern of the display substrate 31 is visually recognized, and the decorativeness is enhanced. The reason why the color tone of the logo mark 47 and the index 57 does not move to the pedestal layer has been described in detail in the description of the above-described embodiment, and thus description thereof is omitted here. Further, since the logo mark 47 and the index 57 are formed on a pedestal layer having a flat surface, a smooth and clean surface free of undulations and undulations can be obtained on the printed surface of the logo mark 47 and the index 57. The logo mark and index having a uniform gloss that does not change the color gloss depending on the viewing direction are visible.

  In the first embodiment, a semi-transmissive reflective film 32 is provided below the display substrate 31, and the surface layer 43 of the pedestal layer 44 and the logo mark 47 have a color tone that matches the color tone of the semi-transmissive reflective film 32. A formation 45 was formed. Since the display boards are grouped in the same system color, it does not feel uncomfortable. The shape of the pedestal layer is not particularly limited, and it is preferable that the size is sufficient to form marks and indicators, and is set appropriately in consideration of the shape of the marks and indicators so as to be easily formed by printing. .

  In the first embodiment, the display plate 30 is provided with the semi-transmissive reflection film 32, and the display plate is colored and the transmittance to the solar cell is secured. Application to a solar cell can also be performed by using a colored display substrate without providing any. If a white pigment is blended in the polycarbonate resin and a transmittance of about 40% is ensured, substantially the same operations and effects as those of Example 1 can be obtained. In the first embodiment, the display substrate 31 is made of polycarbonate resin, but is not limited to polycarbonate resin, and resins such as polyimide resin, polyethylene resin, polystyrene, polyethylene terephthalate resin, and acrylic resin can also be used. Since these resins are excellent in heat resistance, moisture resistance, impact resistance, chemical resistance, etc., they can be preferably used as display plate materials. Further, the display substrate may be formed of a transparent ceramic material, or transparent glass may be used. Concavity and convexity formation when glass is used is formed by an etching method using an etchant.

  In the first embodiment, the concave and convex pattern pattern is a lattice pattern, but other pattern patterns may be used, for example, a circle pattern, a stripe pattern, a Piaget cut pattern, a geometric pattern, a stitch pattern, etc. There may be. If the unevenness of these patterns has an unevenness of 25 μm or more, a pedestal layer composed of three layers effectively acts. If there are irregularities of 25 μm or more, it is difficult to produce a flat surface with a single resin layer even if resin ink with adjusted viscosity is used. If the structure of the pedestal layer consisting of the three layers of the present invention is adopted, even a concavo-convex surface having a considerable level difference can be made flat.

  Next, a decorative member and a display board according to Example 2 of the present invention will be described with reference to FIGS. 5A and 5B are a plan view and a cross-sectional view of a timepiece display panel according to Embodiment 2 of the present invention. FIG. 5A is a plan view, and FIG. 5B is a plan view of FIG. AA sectional drawing is shown. FIG. 6 shows an enlarged view of the portion B in FIG.

  The display board 60 of Example 2 is a display board for watches, and is a display board using a morpho fiber cloth. And the structure which provided the index | index 77 which is the time character which is the decoration member of this invention on the morpho fiber cloth is taken. As shown in FIG. 5, the display board 60 has a morpho fiber cloth 63 affixed on a display substrate 61 made of metal via an adhesive 62, and an index 77 indicating a time character is provided on the morpho fiber cloth 63. A pedestal layer 74 having a flat surface at a position is provided, and an index 77 having a time character is provided on the pedestal layer 74.

  The display substrate 61 used here is a metal plate such as a phosphor bronze plate, a brass plate, or a white plate, and a blank is formed by pressing and surface treatment such as plating is performed.

  Next, the morpho fiber cloth 63 is a morpho fiber cloth which is a woven fiber cloth in which ten morpho fibers 63a are bundled and knitted, and has a thickness of about 150 to 200 μm. The morpho fiber 63a has a multi-layered structure in which 61 layers of polyester and nylon having different refractive indexes are stacked in a thickness of several tens of nanometers. The thickness of one fiber 63a is 15 to 20 μm, and the width is 60 to 60 μm. It is a fiber having an elliptical shape of 70 μm. Morpho fiber emits a color that a morpho butterfly emits due to light reflection, interference, etc., and a very beautiful and beautiful unique appearance color is obtained. This morpho fiber cloth is used after being shaped flat.

  The molding method is performed as follows. The morpho fiber cloth is sandwiched between two smooth glass plates in a sufficiently stretched state, and is heated at about 140 ° C. for 1 hour in a pressurized state. This makes a beautifully woven morpho fiber cloth. However, since it is very thin, its waist is weak and difficult to handle. Therefore, reinforcement is applied to strengthen the waist. In the reinforcing treatment, a thermosetting acrylic resin is sprayed onto one side of the morpho fiber cloth by a spray coating method, and the acrylic resin cured by performing the heat treatment to cure the resin acts as a reinforcing material. Thus, in FIG. 6, 63b is this reinforcing material. By attaching the reinforcing material 63b, a strong morpho fiber cloth can be obtained.

Next, a carbon dioxide laser is used to laser cut into a required shape to obtain a morpho fiber cloth having a display plate shape. Further, a protective film 63d is provided on the other surface of the morpho fiber cloth 63 in order to prevent the morpho fiber from being loosened (gathering the fibers together and becoming loose). The protective film 63d is formed of a very thin film of 5 μm or less using a resin such as urethane resin, epoxy resin, or acrylic resin. The morpho fiber cloth 63 having such specifications is attached to the display substrate 61 via the adhesive 62 with the surface with the reinforcing agent 63b facing down. Also in the morpho fiber cloth 63 formed in this way, uneven steps in the range of 50 to 100 μm occur on the upper surface side.

  The pedestal layer 74 is composed of a guide layer 71 at the bottom, a plane layer 72 in the middle, and a surface layer 73 at the top. The guide layer 71, the plane layer 72, and the surface layer 73 are all transparent, as in the case of using the glass fiber cloth in the above-described embodiment, so that the color emitted by the morpho fiber cloth is not impaired. It is made of a new resin. The specifications of the guide layer 71, the planar layer 72, and the surface layer 73 are formed with the same specifications as the guide layer, the planar layer, and the surface layer in the above-described embodiment.

  The index 77 is composed of a base layer 75 and a finishing layer 76. The base layer 75 is formed of a white resin, and the finishing layer 76 is formed of a resin colored black. The specifications of the foundation layer 75 and the finishing layer 76 are also formed with the same specifications as the specifications of the foundation layer and the finishing layer in the above-described embodiment.

  In the display board 60 having the above-described configuration, a black indicator 77 with a clear outline and a smooth surface and gloss in a beautiful color that the morpho butterfly from the morpho fiber cloth 63 emits is visually recognized. And visually recognized as a highly decorative display board.

  In Example 2, the pedestal layer 74 was formed in a substantially oval shape along the shape of the bar-shaped index 77. It is preferable to select an appropriate shape for the pedestal layer depending on the shape of the index.

  As mentioned above, although both Example 1 and Example 2 demonstrated the display board for timepieces, the decoration member of this invention and a display board are not restricted to the display board for timepieces, but the display boards of various instruments And can be applied to display plates such as various nameplates. Further, the present invention can also be applied to ornaments such as jewelry and figurines.
