BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timepiece dial, a method for manufacturing the same, and a portable timepiece having the same, and more particularly to a solar battery timepiece dial or a backlight timepiece dial.

[0002]

2. Description of the Related Art (First Prior Art) A dial for a watch with a solar cell and a dial for a watch with a backlight have a light transmitting property and thus have a relatively similar dial configuration. The dial plate for a solar cell timepiece is required to have transparency in order to allow light to enter a solar cell (solar cell) arranged on the lower surface side thereof. Conventionally, a transparent plate such as plastic, ceramic, or glass is used because the Bunyu plate for a watch with a solar cell is required to have transparency. In particular, plastics are very often used because they are inexpensive and can be easily molded and processed. In addition, the solar cell arranged on the lower surface side of the timepiece dial has a unique dark purple color and does not have a visually pleasing color tone. Therefore, in order to prevent the dark purple color of the solar cell from being seen, various innovations have been made in the dial for timepieces.

An example of the timepiece dial for solar cell disclosed in the above-mentioned prior art will be described with reference to the drawings. FIG. 26
FIG. 25 is a cross-sectional view of a solar cell-equipped timepiece in a conventional example.

A stepping motor or the like provided in the drive unit 4 is used as a drive source, and is driven via a train wheel mechanism. The dial plate portion 208 has a through hole at the center for passing the hour hand 205, the minute hand 206, and the second hand 207, and is arranged on the timepiece driving movement 204.

Next, the structure of the dial plate portion 208 will be described. As shown in FIG. 25, the dial plate 208 is fixed to the timepiece driving movement 204 by press fitting, caulking or the like via the foot portion 209. In addition, an insulating film 211 is provided on the substrate 210, an electrode film 212 is provided on the insulating film 211, and a solar cell 213 is further arranged so that the transparent electrode 2 is formed.
Cover it with 14. A timepiece dial 216 is arranged above the transparent electrode 214 via a spacer 215. Even if the timepiece dial 216 is warped or the timepiece dial 216 bends due to an external impact, the solar cell (Solar cell) 213 does not hit directly. In addition, the timepiece dial 216 also serves to make the multistage dividing line of the solar cell 213 invisible. The spacer 215 is made of a material that does not transmit light.

FIG. 22 is an enlarged cross-sectional view of an essential part of the timepiece dial 216. The timepiece dial 216 has a metallic sensation and the solar cell 213 is not visible in dark purple. is there. The timepiece dial 216
Has a structure in which a metal film 2 having a large number of small holes 2a provided at equal intervals is formed on the lower surface of a light transmissive substrate 1 made of a transparent plastic plate or the like. And this small hole 2a is 3
It is formed to be smaller than 0 μm. Small hole size is 30
If it is smaller than μm, the pore itself is almost invisible, and therefore the solar cell 213 itself disposed thereunder is also completely invisible.

The solar cell 213 is generally shown in FIG.
As shown in Fig. 3, four planes (A1, A2, A
3, A4) and is provided on the lower surface side of the timepiece dial 216. The amount of transmitted light from the timepiece dial 216 is designed to be radiated equally to the four surfaces. That is, the solar cell 21 is divided into four equal parts by providing the small holes 2a at equal intervals on the lower surface of the light transmissive substrate 1.
The transmitted light is emitted equally to each of the three. Further, the large number of small holes 2a provided at equal intervals is provided such that the total area of the small holes 2a is within the range of 25 to 50% of the area of the timepiece dial 216. If the total area of the small holes 2a is 25%, a transmittance of 25% can be secured and a sufficient amount of power generation can be obtained.
Further, when the total area of the small holes 2a exceeds 50%, the dark color of the solar cell 213 becomes strongly visible.

Next, a method for manufacturing the timepiece dial 216 will be described. The timepiece dial 216 is formed by the process shown in FIG. FIG. 24 is a process explanatory view showing the manufacturing method, and FIG. 24 (a) is a view showing a state in which the metal film 2 is formed on the light transmissive substrate 1 made of a transparent plastic plate or the like, and the metal film 2 is formed by the vapor deposition method. Form. The metal film 2 can be selected from various metals such as aluminum and nickel, and the thickness thereof is formed so that light does not pass therethrough.

Next, FIG. 24 (b) is a view showing a state in which a resist film 3 is formed on the upper surface of the metal film 2 formed in FIG. 24 (a). The resist film 3 is formed by a known method such as printing or painting. Is formed by.

Next, FIG. 24 (c) is a view showing an exposure step, in which the negative pattern film 4 is placed on the upper surface side of the resist film 3 and is irradiated with ultraviolet rays to be exposed.
This negative pattern film 4 is a negative pattern film in the form of a printing object in which a large number of small holes 2 a are made to correspond to the metal film 2 provided at equal intervals.
The resist film 3 is exposed and cured by irradiating ultraviolet rays from above. As a result, the portion of the resist film 3 corresponding to the small hole 2a is not irradiated with ultraviolet rays and is in a soft state.
The other portion (indicated by an arrow in the figure) is irradiated with ultraviolet rays to be in a cured state.

Next, FIG. 24 (d) is a view showing a state in which a small hole 3a is formed in the resist film 3. In FIG. 24 (c), the soft portion of the resist film 3 not exposed (small hole 2a
(Corresponding to the part) is peeled off with a peeling liquid, and the resist film 3 having the small holes 3a is obtained. The small hole 3a portion of the resist film 3 corresponds to the small hole 2a portion of the metal film 2.

Next, FIG. 24 (e) is a view showing a state in which the metal film 2 exposed in the small hole 3a portion of the resist film 3 is peeled off by an etching solution to form the small hole 2a. The small holes 2a are formed by peeling off the exposed metal film 2 with the etching liquid.

Next, FIG. 24 (f) is a view showing a state in which the remaining resist film 3 is completely peeled off to expose the metal film 2. By peeling off the resist film 3 entirely with a peeling liquid, the metal film 2 having the small holes 2a appears. When the metal film 2 of the dial is formed in this manner and the surface of the metal film 2 is used as the lower surface side, the dial for a timepiece 216 having the structure shown in FIG. 22 is obtained.

(Second Prior Art) Next, as a prior art for forming an image, an example in which a sublimable dye is used for color coloring is disclosed in JP-A-11-116692. This is the resin surface of a plastic product obtained by dipping (immersing) an object to be colored, such as a plastic product, in a dye solution in which an oligomer having an affinity for the sublimable dye, such as a polyester resin, contains the sublimable dye. Is a method of coloring. The coloring by this dipping method can be said to be a very cheap method because sufficient coloring can be performed by dipping for only a few minutes.

On the other hand, images such as paintings, photographs, characters and patterns using sublimable dye ink are printed on a transfer paper, and the images printed on the transfer paper are printed on the surface of a metal plate or a glass plate. Transfer images are formed under heat and pressure on the formed receiving layer to form a transfer image on a metal plate, a glass plate, or the like. In this method, a transfer paper on which an image is formed by printing with a sublimable dye ink is superposed on the transferred material on which the image is formed on the lower surface and a receiving layer is formed, and heated under pressure by a pressure device. By pressing, the image is transferred to the receiving layer of the transferred material.

The material to be transferred is composed of a substrate and a receiving layer, and the substrate is made of various materials such as metal, plastic, fiber and glass. Polyurethane resin, polyester resin, or the like is selected for the receiving layer, and is formed by a printing method, a coating method, or the like. When the transfer paper on which an image is formed is superposed on the material to be transferred and pressed under heating, the sublimable dye vaporizes and penetrates into the vaporized dye or the receiving layer to enter the receiving layer. And the same image (exactly the opposite image)
Is drawn.

(Third Prior Art) Further, in the conventional timepiece dial, it is often practiced to apply gold plating or the like to tailor the dial in order to give a metallic appearance and a high-grade appearance. This gold-plated timepiece dial has a very high material cost because it uses expensive gold, and is rather used in high-priced timepieces. In this watch dial, patterns such as Asahi pattern and satin pattern are applied on the surface of a metal plate such as brass material, and a nickel (Ni) plating layer, a silver (Ag) plating layer, and a gold (Au) layer are further formed on the surface. A dial layer for a timepiece is formed by applying a plated layer laminated in order with the plated layer.

There are many kinds of shades, even if it is said gold. They are roughly classified into, for example, "red type", "blue type", and "yamabuki type". In addition, these are also divided into dark and usui.For example, as a "red type", the tone of reddish gold with a deep gold color is "red gold", and the tone of usui a little more than red gold is "us". It is called "red gold".

Further, as the "Yamabuki color system", the gold color tone that is more gold than Usus gold and has almost no redness is called "Us gold", and the color tone of Usui gold is more called "Usus gold". There is. Among such divisions, a watch dial with a tone color of "usus gold" is often used. As described above, the dial plate for a timepiece is often used in a gold color tone of "ususu gold" even in the "yamabuki color system". The dial for the watch is plated with cyan gold to obtain this "Usus gold" tone. When plating is performed using this cyan gold, the color tone of "usus gold" can be obtained by adjusting the applied voltage and current value in plating, the plating time, and the like.

[0019]

(Problems to be solved by the first conventional technique) However, the dial plate for a solar cell timepiece formed by the method of the first conventional technique has a metallic feeling.
Moreover, the dark purple color of the solar cell becomes invisible. However, in a colored timepiece dial, it was difficult to obtain a timepiece dial having a high-quality appearance quality because a bright and vivid color tone could not be obtained. In addition, the manufacturing method also has a very high cost because of the large number of manufacturing steps. Also, because the small holes are very small,
Dimensional accuracy and positional accuracy are also affected by the thickness of the resist film, expansion and contraction of the film, side etching of the metal film, etc.
It was difficult to finish it very accurately. Therefore, the yield is low and it is not suitable for mass production. Moreover, since an etching solution or a stripping solution is used, it cannot be said that the work is physically preferable.

(Problem with Second Prior Art)
Like the prior art of, although the object to be colored colored by dipping (immersion) and the transfer image formed by transferring the image printed on the transfer paper can initially obtain a clear image, When used for a long period of time in the presence of outside light or when the outside temperature fluctuates, there is a problem in that the color tone of the image changes or the color tone fades and the image becomes unclear. This is because the sublimable dye is vulnerable to ultraviolet rays and is easily deteriorated by ultraviolet rays.

In addition, the portable timepiece is constantly worn on the wrist and used as it is exposed to ultraviolet rays every day.
For this reason, a structure is adopted that sufficiently guarantees the light resistance against ultraviolet rays and the like. For example, for a dial of a portable timepiece, a light resistance test called a sunshine weather meter test for evaluating the light resistance of ultraviolet rays is performed to guarantee the light resistance. For watch parts, the wet test of this sunshine weather meter gave 100
It is recognized that sufficient light resistance can be guaranteed if the time can be guaranteed. When the wet test of the sunshine weather meter was carried out on the dial produced by the above-mentioned conventional technique, the dial faded after about 30 hours, and there was a problem that it could not be used at all for a dial for a timepiece.

(Problem with Third Prior Art)
In the related art, the material cost of gold is high in order to obtain a timepiece dial that is gold-plated by gold plating, and the backside of the watch dial that is completely invisible is also gold-plated, so the material cost is high. There is a lot of waste. The emergence of a watch dial with a metal color equivalent to that of gold plating at a low cost has become a problem.

(Purpose) The present invention has been made in view of the above problems, and has a concave portion having a reflective film on the lower surface of a light-transmissive substrate made of transparent plastic and a light-transmissive material (transparent material) of invisible size. Of the solar cell to prevent the dark purple color of the solar cell from being visible, and the light-transmitting substrate has sufficient light resistance and sublimates a bright and colorful color image. An object of the present invention is to provide a colorful timepiece dial made of a functional dye and a mobile timepiece using the same. Another object of the present invention is to provide a timepiece dial which makes a metallic color equivalent to that of gold plating appear by using a sublimable dye and gives a low-grade feeling, and a portable timepiece using the dial. Furthermore, it is a simple operation and can be manufactured at a low cost,
Moreover, it is an object of the present invention to provide a method for manufacturing the above-mentioned dial for timepiece, which can be manufactured with high accuracy and can be manufactured by a safe work that does not harm the body.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) Hereinafter, a timepiece dial according to a first embodiment of the present invention will be described with reference to FIG.
A description will be given based on FIG. FIG. 1 is an enlarged view of a main part of a timepiece dial, FIG. 1 (a) is an enlarged cross-sectional view of the main part, and FIG.
FIG. 2 is an enlarged perspective view of an essential part of the timepiece dial shown in FIG. Further, FIG. 2 shows a cross-sectional view of a dial portion including a dial for watch, a solar cell (solar cell) and the like.

First, the structure of the timepiece dial for solar cell according to this embodiment will be described. As shown in FIG. 2, the timepiece dial 10 with a solar cell has a solar cell (solar cell) 213.
It is arranged on top of. Further, as shown in FIG. 1A, the light-transmissive substrate 11, which is the main body of the timepiece dial 10, is
UV absorber 1 made of transparent polycarbonate resin
3 is dispersed and compounded. Further, the light transmissive substrate 11
A color image 14 is formed by permeating a sublimable dye therewith.

The color image 14 is (1) colored over its entire surface with one color. (2) Partial letters, numbers, marks, etc. (3) A mixture of (1) and (2) above. (4) White and black. (5) Paintings, photographs and patterns. Etc. all images are included. Also, this dial 10 for watches
Although not shown in the drawing, marks such as time characters and marks are formed on the upper surface side of the light transmissive substrate 11 to complete the finish.

The ultraviolet absorber 13 is made of ultrafine zinc oxide, and 1 part by weight of ultrafine zinc oxide is mixed with 100 parts by weight of transparent polycarbonate resin which is a material of the light transmitting substrate 11. This ultrafine zinc oxide has excellent ultraviolet absorbing performance as well as ultrafine titanium oxide, and since ultrafine zinc oxide is transparent and does not affect the image tone, it is suitable for ultraviolet protection. Is. Further, since the ultrafine zinc oxide is also excellent in antibacterial action, it is possible to obtain a good hygienic effect by providing it on the outermost surface.

In the present embodiment, 1 part of ultrafine zinc oxide is used.
Although the compound is used in an amount of 0.5 part by weight, it is possible to obtain a sufficient UV absorbing effect by adding 0.5 to 1.5 parts by weight. When the sunshine weather meter test of the timepiece dial 10 having the above-mentioned configuration in a wet state was conducted for 200 hours, no deterioration of the image was observed and very good light resistance performance was obtained.

The upper surface of the light transmissive substrate 11 is made flat and smooth by polishing. Further, the lower surface has concave and convex portions formed of pattern-shaped concave portions 11b and convex portions 11a, and the concave portions 11b are densely arranged in a matrix. The bottom surface of the recess 11b is mirror-finished, and a metal reflection film 12 is formed on the inner surface of the recess 11b. Further, the upper surface (corresponding to the lower surface in the figure) 11c of the convex portion 11a is polished to expose a part of the light transmissive substrate 11, and is formed into a smooth surface to serve as a light transmissive portion.

FIG. 1B is a perspective view of the main parts as seen from the lower surface side of the timepiece dial 10. The convex portions 11a and the concave portions 11b are formed in a grid pattern side by side at regular intervals and form a grid pattern as a whole. Further, in FIG. 1A, the width (t) of the polished upper surface 11c of the convex portion 11a is 120.
The total area of the upper surface 11c of the convex portion 11a is 20 μm or less with respect to the area on the upper surface side of the light transmissive substrate 11.
It is formed in the range of up to 50%.

The metal reflection film 12 formed on the inner surface of the recess 11b is a metal vapor deposition film formed by vapor deposition of metal, and is formed to a thickness such that light does not pass therethrough. The reflective film is not particularly limited to metal, and may be a paint film formed to have a thickness that does not transmit light by printing or painting. Further, after applying the reflection film, a coating film may be laminated to form the reflection film.

In the timepiece dial 10 having the above structure,
In the concave portion 11b, light is not transmitted by the reflection film 12, but rather the reflection effect appears and the color tone of the reflection film 12 is visible. Further, light is transmitted through the portion of the convex portion 11a and is incident on a solar cell (not shown) arranged on the lower surface thereof. And
Since the upper surface 11c of the convex portion 11a is a smooth surface, it is incident without scattering and the incidence efficiency is improved.

Further, although light is transmitted through the convex portion 11a, the dark purple color of the solar cell 213 is hardly visible because the width of the upper surface 11c thereof is very small. The color image 1
Even in the light-transmissive substrate 11 on which No. 4 is formed, since the color image 14 has transparency, the dark purple of the solar cell 213 is hardly confirmed.

Further, since the total area of the upper surface 11c of the convex portion 11a is formed within the range of 20 to 50% of the area on the upper surface side of the dial plate 10, a sufficient amount of light for power generation of the solar cell 213 can be given. . In recent years, solar cells that have a transmittance of at least about 20% and that can generate a sufficient amount of power have been emerging. Therefore, the total area of the upper surface 11c of the convex portion 11a, which is a light transmitting portion, is 20% of the area on the upper surface side of the dial 10, and a transmittance of 20% is obtained, and a light amount that does not hinder power generation is obtained. Become. Further, the upper surface 1 which is a light transmitting portion.
When the total area of 1c exceeds 50% of the area on the upper surface side of the dial 10, the reflective film 12 becomes inconspicuous and the solar cell 21
The dark purple color of 3 becomes noticeable. From this, the total area of the upper surface 11c, which is the light transmitting portion, is
By setting it within the range of 20 to 50% on the upper surface side of 0, a sufficient amount of power generation is obtained, and the reflection film is large so that the light transmitting portion of the convex portion 11a is not conspicuous to the eyes.

In this embodiment, the concavo-convex pattern is formed in a lattice pattern, or various patterns such as a stripe pattern, a circle pattern, a Asahi pattern, and a geometric pattern can be similarly selected.

As described above, in the present embodiment, since the concave portion 1b on the lower surface provided with the reflective film is made to be a mirror surface, the reflectance of light from the reflective film is increased, whereby the upper surface 11c of the convex portion 11a is increased. Even if the size (width t) of the light transmitting portion was increased to 120 μm, the dark purple of the solar cell 213 could not be seen. FIG. 27 shows the result of an experiment in which the width t of the recess 11b was changed. If the width t of the upper surface 11c of the convex portion 11a is up to 120 μm, the concave portion 1c cannot be recognized from above the dial plate 10. Width t is 130μ
At m, you can see it a little.

Even when the image 14 is formed on the timepiece dial 10, by making the convex upper surface 11c smooth, almost all the light can be transmitted from above and the transmittance is not lowered.
In addition, since the uneven portions are arranged at regular intervals, a uniform light amount can be obtained in the solar cell. If the area of the transparent portion is 20 to 50%, sufficient power generation and efficient power generation can be obtained. Further, since all the patterns are vertically and horizontally symmetrical, a uniform amount of light can be obtained at each part of the solar cell 213.
The reflective film 12 is most preferably a metal (silver, aluminum, etc.) vapor deposition film having a high reflectance. In addition, since it is a mirror surface, a metallic luster appears and a metallic feeling can be obtained. In the case of a paint film, paints having various color tones can be used, but a paint having a high reflectance can provide a good effect.

As described above, according to this embodiment, the reflective film 1 is formed on the lower surface of the light transmissive substrate 11 made of transparent plastic.
The concave portion 11b provided with 2 and the convex portion 11a having an invisible light transmissivity (transparency) are formed in a pattern,
The dark purple of the solar cell 213 is made invisible, and the light-transmissive substrate 11 has a sufficient light resistance and a bright and vivid color image 14 is formed by a sublimable dye.
It is possible to realize a colorful dial 10 for a timepiece.

(Manufacturing Method) Next, the dial 10 having the above structure
The manufacturing method will be described with reference to FIG. FIG. 12 is a process explanatory view showing the manufacturing process of the dial 10, and is shown in a sectional view of an essential part. First, the concavo-convex portion is formed on the dial blank made of the light-transmissive plastic substrate. FIG. 12A shows a blank 11A of the light transmissive substrate 11 having a concave portion 11b and a convex portion 11a on the lower surface formed by the injection molding method.
This blank 11A is molded by injecting a light-transmissive resin into a mold by heating and pressurizing using an injection molding device. Since the concavo-convex portion on the lower surface is formed by transfer from the concavo-convex portion formed on the mold, the convex surface of the mold corresponding to the bottom surface of the concave portion of the dial is mirror-finished in advance. The light-transmitting resin, which is a material for injection molding, is made of transparent polycarbonate resin, and 100 parts by weight of this polycarbonate resin is mixed with 1 part by weight of ultrafine zinc oxide as the ultraviolet absorber 13. .

Next, FIG. 12B is a view in which the reflection film 12 made of a metal vapor deposition film is formed on the entire lower surface having the uneven portion. A metal vapor deposition is performed on the entire lower surface of the blank 11A of the light transmissive substrate 11 formed by the injection molding method by a vapor deposition apparatus to form a reflection film 12 of a metal vapor deposition film. This metal vapor deposition film is formed to a thickness (approximately 1000 or more) that does not allow light to pass through. The reflective film 12 may be a paint film formed by a coating method to a thickness such that light does not pass therethrough.

Next, FIG. 12 (c) is a view showing a state in which the upper surface of the convex portion 11a is polished to remove the reflection film 12 and finished into a smooth convex upper surface 11c. The polishing apparatus polishes the upper surface side of the convex portion 11a on which the reflective film 12 is formed to such an extent that the light-transmissive substrate is exposed, removes the reflective film 12 and finishes the smooth convex portion upper surface 11c. In this embodiment, the polishing method is used to raise the surface to a smooth surface, but a cutting method using a cutting tool with a diamond tip may be used to raise the surface to a smooth surface.

Next, FIG. 12D shows the light transmissive substrate 1
FIG. 3 is a diagram showing a state in which a sublimation dye is permeated on the upper surface side of No. 1 by a transfer method to form a color image 14. Also, in FIG. 17,
17 shows a state in which a color image is formed by transfer, and FIG.
17A is a sectional view showing a state before transfer and FIG. 17B is a sectional view showing a state after transfer. As shown in FIG. 17A, the mounting tool 111
The light transmissive substrate 11 is placed on the above. Next, the transfer paper 112 on which the color image 112a printed with the sublimable dye ink is formed is placed on the light transmissive substrate 11, and the transfer paper 112 is set to about 180.
While being heated to about 0 ° C., the sublimable dye on the transfer paper 112 is vaporized by applying a pressure of about 10 g / cm ² for about 1 minute to vaporize the sublimable dye into the light transmitting substrate 11 to transfer and form the color image 14. To do. Through the above manufacturing process, the dial 1 for a watch having sufficient light resistance and having a bright and colorful color image
I got a dial.

In this embodiment, a light-transmitting substrate 11 having irregularities on one side is formed by an injection molding method using a mold, but as another method, the method shown in FIG. is there. FIG. 16 shows a flat mounting table 4
A light-transmissive plastic plate 11B, in which an ultraviolet absorber 13 is mixed and dispersed in advance, is placed on the surface 2 and the unevenness (43
a) and 43b) are formed on the light transmitting substrate 1 shown in FIG.
A blank having the same shape as the blank 11A can be obtained.

According to the above manufacturing method, the light transmissive substrate 1
Since the pattern-shaped concave-convex part 1 is formed by transfer from the pattern-shaped concave-convex shape formed on the mold or the pressing tool, it is possible to form the pattern-shaped concave-convex part with very stable accuracy with little variation in size and shape. Further, since the mold or pressing tool having the uneven shape can be used for a long period of time and the manufacturing and processing time can be shortened, mass productivity is excellent and the processing cost can be very low. In addition, since post-processing also employs simple processing methods such as vapor deposition processing, coating processing, and polishing processing, the total processing time can be reduced and the cost can be very low. Furthermore, since the conventionally used stripping solution or etching solution is not used, there is no adverse effect on the body and healthy work can be performed.

The method of transferring the sublimable dye of the transfer paper has been described as a method of forming a color image on the upper surface side of the light transmissive substrate 11. However, in addition to this, a dye solution containing a sublimable dye is used. A dipping method of dipping (immersing) the transparent substrate 11 in a heated state and coloring the transparent substrate 11 can also be used. However, the image obtained by this dipping method (dipping) is limited to "an image which is colored in one color over the entire surface". Further, when a metal film is used as the reflective film 12, the transfer process in the above-described manufacturing process may be changed to a dipping process, but when a paint film is used as the reflective film, the dipping process is performed. In the process, the sublimation dye permeates into the paint film provided as the reflective film to be colored, and the function of crying reflection may be deteriorated. Therefore, it is necessary to change the manufacturing process. This will be described in detail in the second embodiment below.

(Second Embodiment) A timepiece dial according to a second embodiment of the present invention will be described below with reference to FIGS. 3 and 13. FIG. 3 is an enlarged view of a main part of the timepiece dial. Further, FIG. 13 is a process explanatory view showing the manufacturing process of the timepiece dial, and is shown in a cross-sectional view of the main part. As shown in FIG. 3, the timepiece dial 20 in this embodiment is different from the first embodiment in the following points. Light transmissive substrate 21
Has a second uneven portion 15 on the upper surface side. In addition, the reflection film 22 is composed of a paint film. Further, a dipping method is used as a method of forming the image 24, which makes the manufacturing process different from that of the first embodiment.
The other points are similar to those of the first embodiment, and thus the description thereof is omitted.

In FIG. 3, the timepiece dial 20 in this embodiment has a light-transmissive substrate 21 having a concave portion 21b and a convex portion 21a on its lower surface and a second uneven portion 15 on its upper surface, and The transparent film 21 has a reflection film 22 provided in the lower surface recess 21b of the transparent substrate 21. The ultraviolet light absorber 13 is dispersed and mixed in the transparent substrate 21. The concave portion 21b and the convex portion 21a provided on the lower surface side of the light-transmissive substrate 21 and the ultraviolet absorbent 13 are the same as those of the timepiece dial 10 of the first embodiment shown in FIG. The image 24 formed on the light-transmissive substrate 21 is colored in one color over the entire surface.

Further, the reflection film 22 formed in the recess 21b.
Is made of a paint film and is formed to a thickness such that light does not pass therethrough. The second concavo-convex portion 15 provided on the upper surface side of the light-transmissive substrate 21 forms a satin pattern having minute irregularities. The second concavo-convex portion 15 has a Asahi pattern in addition to the satin pattern,
Various patterns such as various stitch patterns and various geometric patterns can be selected. However, a pattern different from the concavo-convex pattern formed by the concave portions 21b and the convex portions 21a provided on the lower surface side of the light transmissive substrate 21 is selected. When the second uneven portion 15 is provided on the upper surface side of the light transmissive substrate 21 as described above, light is refracted at that portion and emitted in various directions, so that the dark purple of the solar cell becomes difficult to see and the second As the pattern is visible, the decorativeness increases. In particular, when the second concave-convex portion 15 has a fine pattern, dark purple is not visible at all.

As described above, in the present embodiment, the pattern of the second concave and convex portions 15 formed on the upper surface of the light transmissive substrate 21 has the pattern of the reflection film 22 formed on the lower surface recess 21b of the light transmissive substrate 21. Color tone and image 2 formed on the transparent substrate 21
You get a dial that looks like a combination of four tones. Other functions and effects are the same as those in the first embodiment, and thus the description thereof will be omitted.

Next, a method of manufacturing the dial plate 20 having the above structure will be described with reference to FIG. FIG. 13 (a) shows a blank 21A of the light transmissive substrate 21 having a concave portion 21b and a convex portion 21a formed on the lower surface by the injection molding method, and a second uneven portion 15 having a satin pattern on the upper surface. The concave portions 21b and the convex portions 21a on the lower surface and the second concave and convex portions 15 on the upper surface are formed by transferring from a mold. The light-transmitting resin, which is a material for injection molding, is made of transparent polycarbonate resin, and 100 parts by weight of this polycarbonate resin is mixed with 1 part by weight of ultrafine zinc oxide as the ultraviolet absorber 13. .

Next, FIG. 13B is a diagram showing a state in which the sublimation dye is permeated into the light transmissive substrate 21 by the dipping method to form the color image 24. The image 24 is colored in one color over the entire surface. Hereinafter, a method of coloring the color image 24 will be described. In this color coloring method, a sublimation dye solution heated to about 110 ° C is immersed for about 1 minute, washed and dried after immersion, and heated to about 180 ° C for about 10 to 20 ° C.
Under the pressure of g / cm ^2, the upper surface side of the light transmissive substrate 21 is pressed by a pressure device to be colored.

In the state of being immersed in the sublimable dye solution, the depth of immersion of the dye in the light-transmissive substrate 21 is shallow, and the depth of immersion of the dye is deepened by heating and pressurizing in the subsequent step, so that the coloring hue is increased. It can last very long.

The sublimation dye solution is a solution in which a sublimation dye having plasticity which is compatible with the dye is mixed, and in this embodiment, 100 parts by weight of the polyester resin is mixed with approximately 4 parts by weight of the sublimation dye. is there. Although this solution is immersed in the heated state to be colored, the immersion time is appropriately set in consideration of the heating temperature of the solution, the concentration of coloring, etc., but it is generally about 1 to 3 minutes. . Even if it is soaked for 3 minutes or more, the color density hardly changes. The color density is convenient because it can be freely adjusted by adjusting the immersion time.

Although the heating temperature of the dye solution is slightly different depending on the binder used, in the polyester resin of the present embodiment, when it is set within the range of about 100 to 120 ° C., coloring is possible with the above immersion time. Become. When the temperature is low, coloring takes time, and when the temperature is high, coloring is performed quickly.

After the light-transmissive substrate 21 is colored in this way, it is washed and dried, and then heated to a temperature near the softening point of the binder forming the light-transmissive substrate 21 to apply pressure to the dye. The immersion depth of swells deeper. If this pressure is small, the penetration is shallow, and if it is large, the light transmissive substrate 21 is deformed by compression. A pressure of approximately 10 to 20 g / cm ² is sufficient.

Next, FIG. 13C is a view in which the reflective film 22 made of a paint film is formed on the entire lower surface of the blank 21A of the light transmissive substrate 21 on which the concave and convex portions (21b, 21a) are formed. The reflection film 22 made of a paint film is formed by coating on the entire lower surface of the blank 21A of the light transmissive substrate 21 on which the image 24 is formed by the dipping method.
This paint film is formed to a thickness that does not allow light to pass through.

Next, FIG. 9 (d) shows a state in which a part of the peak of the convex portion 21a is shaved off by the polishing method or the cutting method to expose the blank 21A, and a smooth upper surface 21c is formed on the convex portion 21a. There is. The reflection film 22 by the polishing device
The upper surface side of the convex portion 21a formed with is formed to such an extent that the light transmissive substrate 21 is exposed, the reflecting film 22 is removed, and a smooth convex upper surface 21c is finished. In this embodiment, the polishing method is used to finish the surface to be smooth, but the cutting method using a diamond tool or the like may be used to finish the surface to be smooth. By performing color coloring in the manufacturing process as described above, the dye penetrates deeply into the light-transmissive substrate 21, and at the same time, the timepiece dial 20 is provided with color coloring that is significantly improved in light resistance to ultraviolet rays. It was When the sunshine weather meter test was performed for 100 hours in a wet state on the timepiece dial 20 having the above structure, no deterioration of the image was observed and very good light resistance performance was obtained.

As described above, according to the method of manufacturing the timepiece dial of the present embodiment, the manufacturing method is simple and the number of manufacturing steps is small, so that the timepiece dial can be manufactured at a low cost. In particular, dipping (immersion) the blank 21A of the transparent substrate 21.
However, the method of coloring the blank 21A is a very inexpensive method because sufficient coloring can be performed by dipping for only a few minutes.

In the first and second embodiments, the ultra-fine zinc oxide is used as the ultraviolet absorbent 13 by way of example, but the same effect can be obtained with the fine titanium oxide ultraviolet absorbent. Can be done. In addition, 100 parts by weight of the polycarbonate resin, which is the material of the light transmissive substrate 21, is an organic compound suitable for high temperature processing, and the chemical formula is

[Chemical 1] The same effect can be obtained even when 2.5 parts by weight of the ultraviolet absorber is mixed. Further, in the first and second embodiments, both use a single ultraviolet absorber, but similar effects can be obtained by mixing these ultraviolet absorbers.

As shown in FIG. 4, the timepiece dial 30 in this embodiment is different from the first embodiment in the following points. The light-transmissive substrate 31 does not include a UV absorber dispersedly mixed therein, and has a transparent protective film 16 on the upper surface side of which the UV absorber 23 is mixed. The other points are similar to those of the first embodiment, and thus the description thereof is omitted.

In FIG. 4, the timepiece dial 30 according to the present embodiment has a concave portion 31b and a convex portion 31a on the lower surface thereof, and the light transmitting substrate 31 on which the color image 14 is formed.
A reflective film 12 provided in the lower surface recess 31b of the light transmissive substrate 31, and a transparent polyurethane resin 100 thereon.

The concave portion 31b and the convex portion 321a provided on the light transmissive substrate 21, the reflective film 12 provided on the concave portion 31b, and the color image 14 are the dial plate 10 for a watch according to the first embodiment shown in FIG. Is the same as.

The transparent protective film 16 is provided to protect the color image 14, and is formed by a printing method or a coating method using a paint such as a transparent urethane resin or acrylic resin. Then, the upper surface of the transparent protective film 16 is polished to a glossy smooth surface.

As a result of the sunshine weather meter test for 100 hours in the wet state of the timepiece dial 30 having the above-described structure, no alteration was observed in the transferred image, and the watch dial 30 having good light resistance was obtained. It was

The transparent protective film 16 in this embodiment is
The thickness is about 20 μm, but if it is thin, the light resistance deteriorates, so it is preferable that the thickness is at least 10 μm or more. On the other hand, if it is too thick, the color tone of the ultraviolet absorber will appear dark and the image will be toned, resulting in a marked change in the image tone.
As a result of the experiment, a color tone comparable to the image tone was obtained when the thickness was 30 μm at the most. Therefore, the transparent protective film 16
It can be said that a thickness in the range of approximately 10 to 30 μm is preferable.

It shows the finished surface. The step of forming the transparent protective film 16 is performed by using the transparent polyurethane resin 100.
Chemical formula for parts by weight

[Chemical 3] Which is represented by the following formula: 2.5 (part by weight) of a UV absorber 23 of 2- (3-t-butyl-5-methyl-2-hydroxyphenyl) -5-chlorobenzotriazole is dispersed and blended to form a paint
The transparent protective film 16 having a thickness of about 20 μm is formed by printing or coating.
To form. Through the above manufacturing process, the timepiece dial 30 having sufficient light resistance and having a bright and colorful color image was obtained.

In this embodiment, an example in which the ultraviolet absorbent is not dispersed and compounded in the light transmissive substrate 31 has been described.
As shown in FIG. 5, similar to the first embodiment, the same effect can be obtained by dispersing and blending ultrafine zinc oxide as the ultraviolet absorber 13 in the light transmissive substrate 11.

(Fourth Embodiment) A timepiece dial according to a fourth embodiment of the present invention will be described below with reference to FIGS. 6 and 15. FIG. 6 is an enlarged view of a main part of the timepiece dial. Further, FIG. 15 is a process explanatory view showing the manufacturing process of the timepiece dial, and is shown in a sectional view of the main part.

As shown in FIG. 6, the timepiece dial 50 in this embodiment is different from the first embodiment in the following points. The light-transmissive substrate 41 does not have a UV absorber dispersed and blended therein, and a color image is not formed. Further, an ultraviolet absorber is dispersed and blended on the upper surface side of the light transmissive substrate 41,
It has a receiving layer 17 on which a color image is formed. Other points are the same as in the first embodiment.

In FIG. 6, a timepiece dial 50 in the present embodiment has a light transmissive substrate 41 having concave portions 41b and convex portions 41a on its lower surface, a reflective film 12 provided in the lower concave portion 41b, and It is composed of the receiving layer 17 having the transfer image 34 formed on the upper surface of the light transmissive substrate 41.

The receiving layer 17 comprises 2- (3,5-di-t-butyl-2) in 100 parts by weight of a transparent polyurethane resin.
A hydroxy paint 33-hydroxyphenyl) benzotriazole is applied by coating with a coating composition in which 2.5 parts by weight of the ultraviolet absorber 33 is dispersed and mixed to a thickness of about 20 μm, and its surface is smoothed by polishing.

Then, the transfer image 34 is transferred to the receiving layer 17 from the transfer paper on which the print image is formed with the sublimable dye ink by heating at 180 ° C. and under a pressure of 10 g / cm ^2. Is forming.

As a result of the above-mentioned constitution, in the result of 100 hours of the wet test of the sunshine weather meter, no alteration was observed in the transferred image and very good light resistance was obtained.

No. 3 has a light yellow color in the powder form, and the blending amount must be set in consideration of the light resistance performance and the color tone of the receiving layer. If the blending amount is too small, the light fastness becomes poor, and conversely, if the blending amount is too large, the light fastness becomes very good, but the receiving layer 17 is colored, and the toned image appears in the transferred image so that the original image tone cannot be obtained. Occurs. As a result of various experiments, a preferable range is approximately 0.5 to 10% by weight.

Further, although the two-component polyurethane resin is used as the binder of the receiving layer 17, the binder is not limited to this, and resins such as polyester resin, epoxy resin and acrylic resin can be selected.

The thickness of the receiving layer 17 influences the depth of penetration of the sublimable dye and is a very important control factor. If the thickness is shallow, the dye will come out due to temperature changes and the image will fade. Receptive layer 1 from experimental results
It was found that the thickness of 7 is preferably 10 μm or more. Further, the thicker one is not particularly limited, and the thicker one is preferable because the depth of penetration of the dye can be deepened, and the deeper one can suppress the escape of the dye. On the contrary, there is a problem that the printing cost becomes high. It is sufficient for the thicker one to have a thickness of 80 μm. Further, when the surface of the receiving layer 17 is a polished and glossy smooth surface, the entire surface is transferred under a uniform pressing force, so that the transferred image does not cause color unevenness and is beautifully transferred. An image is obtained.

As described above, in the third embodiment,
An ultraviolet absorber, 2- (3-t-butyl-5-methyl-2-hydroxyphenyl) -5-chlorobenzotriazole, is selected, and in the fourth embodiment, 2- (3,5-
The UV absorber di-t-butyl-2-hydroxyphenyl) benzotriazole was selected. UV Absorber In the third and fourth embodiments, a single UV absorber is used, but similar effects can be obtained by mixing two UV absorbers. . Fork, third

FIG. 15A shows a blank 41A of the light transmissive substrate 41 having a concave portion 41b and a convex portion 41a on the lower surface formed by the injection molding method. This blank 41A is
This is the same as the manufacturing process in the third embodiment. The steps shown in FIGS. 6B and 6C are also the same as the manufacturing steps in the third embodiment, and the description thereof will be omitted.

Next, as shown in FIG. 15D, the receiving layer 17 is formed on the light transmissive substrate 41 by a printing method or a coating method, and the upper surface of the receiving layer 17 is smoothed by a polishing method. The finished state is shown. In the process of forming the receiving layer 17, the chemical formula is applied to 100 parts by weight of the transparent polyurethane resin.

[Chemical 2] The UV absorber 33 of 2- (3,5-di-t-butyl-2-hydroxyphenyl) benzotriazole is blended in an amount of 2.5 parts by weight to form a paint, which is printed or applied to a thickness of about 20 μm. The receiving layer 17 is formed by a method.

Next, FIG. 15E is a diagram showing a state in which a sublimation dye is permeated into the receiving layer 17 by a transfer method to form a color image 34. In the color image forming step, the transfer image 34 is formed by transferring the image from the transfer paper on which the print image is formed with the sublimable dye ink under heating at 180 ° C. and pressure of 10 g / cm ² . This step is also the same as that of the first embodiment, so the description thereof will be omitted. Through the above manufacturing process, the timepiece dial 50 having sufficient light resistance and having a bright and vivid color image was obtained.

Incidentally, as shown in FIG. 7, the transparent protective film 16 is formed on the upper surface of the timepiece dial 50 in the present embodiment,
The same effect can be obtained as the timepiece dial 60. The transparent protective film 16, the method for forming the transparent protective film 16, and the effects thereof are the same as those of the transparent protective film 16 described in the third embodiment, and thus the description thereof will be omitted.

(Fifth Embodiment) A timepiece dial according to a fifth embodiment of the present invention will be described below. The watch dial in this embodiment is a watch dial finished in gold, and has a light-transmissive substrate having a concave and convex portion on its lower surface, a metal reflection film provided in a recess on the lower surface, and the light-transmissive substrate. And a receptive layer having a transferred image formed on the upper surface of the substrate. On the receiving layer, a transfer paper on which dots are formed by an inkjet printer is formed by using yellow and red or an orange sublimation dye ink obtained by mixing them in a predetermined amount. It is set to have a golden color tone by adjusting the hue.

Here, when the dots are transferred from the transfer paper to the receiving layer, the dye of the printing dots may not be sufficiently mixed, and the transfer dots may be visually recognized as spots.
In the present embodiment, when the dots are transferred from the transfer paper to the receiving layer, the transfer is performed through a transparent film sheet, whereby when the transfer paper is transferred to the film sheet and further transferred to the receiving layer, The dyes mix well and prevent the formation of dot-like spots.

Further, in the present embodiment, a dye-permeated film sheet is transferred from a transfer paper on which dots are printed by using yellow and red or orange sublimation dye ink obtained by mixing them in a predetermined amount. Further, it is configured so as to be further transferred to the receiving layer. Also in this case, it is possible to prevent the generation of dot-like spots as in the case where the transparent film sheet is interposed.

Furthermore, in the present embodiment, two sublimation dye inks of yellow and red are permeated and mixed uniformly at a predetermined ratio, or yellow and red sublimation dye inks are mixed at a predetermined amount. By using the orange sublimable ink, a gold color tone adjusted to a desired hue is obtained. In this way, by submerging the sublimable dye ink into the receiving layer without using gold plating, it is possible to obtain a gold color tone corresponding to gold plating at low cost. Further, the light resistance can be improved by providing a transparent protective film containing an ultraviolet absorber or using a receiving layer containing an ultraviolet absorber.

EXAMPLE A gold-colored timepiece dial according to an example of this embodiment will be described below. FIG. 10 is an enlarged view of a main part of a gold-colored timepiece dial finished in gold. In this embodiment, a configuration for obtaining "usus gold" gold-colored tone will be described.

The timepiece dial 90 shown in FIG. 10 is the same as the timepiece dial 90 of the present embodiment except that a recess 41 is formed on the lower surface thereof.
b, a light-transmissive substrate 41 having a convex portion 41a, a metal reflection film 32 provided in the lower concave portion 41b, and a gold color tone as a transfer image 54 formed on the upper surface of the light-transmissive substrate 41. And the receiving layer 17 formed. The metal reflection film 32 is a vapor deposition film of silver (Ag).

The receiving layer 17 is formed on the upper surface of the light transmissive substrate 41 by a method such as printing using a coating material in which an ultraviolet absorber is dispersed. This UV absorber is
Since it is similar to the receiving layer 17 in the above embodiment, the description thereof will be omitted. A sublimation dye is infiltrated into the receiving layer 17 by a transfer method which will be described later, and is set to "usus gold" by setting as follows.

That is, first, a sublimation dye ink is used to print on a transfer paper with an inkjet printer.
This printing is performed by printing sublimable dye inks of two colors of "red" and "yellow" on the transfer paper of its own color with dots having a size of about 1440 dpi. "Yellow" at this time
The dot printing area is set to about 8%, the "red" dot printing area is set to about 2%, and the remaining white background area is set to about 90%. The "yellow" and "red" dots are stacked. Disperse evenly so as not to.

Next, this transfer paper is placed on the smooth surface of the receiving layer 17, and the heating / pressurizing conditions differ depending on the resin forming the receiving layer 17, but for example, in a hall using polyurethane resin, Heating temperature about 180 ° C, applied pressure 10 g / cm ²
Heat and pressurize for about 40 seconds. As a result, the sublimable dye of the transfer paper is vaporized and permeates the receiving layer 17, so that the receiving layer 1
A desired gold color tone is transferred to 7.

In the gold color tone formed in this way, since the transfer is carried out while applying pressure, the dyes of adjacent dots of different colors may not be sufficiently mixed, and the dot shape is maintained after the transfer. Sometimes Moreover, since the individual dots become considerably large when they permeate, the transfer dots may be visually recognized as spots in some cases. For example, when arranging a small number of "red" print dots in a large number of "yellow" print dots to produce a "light orange", it is not noticeable visually, but if you enlarge it a little, the "red" transfer dots Are visually recognized as "red" spots. If this is "dark orange," it is barely noticeable. This is a phenomenon caused by printing with an inkjet printer. This phenomenon cannot be eliminated even if the heating temperature or the pressure is adjusted without significant change.

In order to erase the dot spots as described above,
There is a method of reheating the receiving layer.However, in this reheating step, it is necessary to heat the dye in the receiving layer so that the dye or convection flows in order to sufficiently mix the dot-shaped dye in a short time. It was When the receiving layer is heated at such a high temperature, the vaporized dye may escape from the receiving layer. Further, the transparent protective film such as clear coating provided on the receiving layer may be soaked with dyes to cause color unevenness. In the present embodiment, the use of the transparent film sheet without reheating prevents the above-mentioned spots from occurring. The transfer using this transparent film sheet will be described below.

FIG. 18 shows a state in which a color image is formed by transfer using a transparent film sheet.
18A is a sectional view showing a state before transfer, and FIG. 18B is a sectional view showing a state after transfer. As shown in FIG. 18A, the mounting tool 111
The timepiece dial 90 described above is placed on the above. Here, dots are printed on the transfer paper 112 at a predetermined ratio as described above. Also, a transparent film sheet 115
Is sandwiched between the transfer layer 112 and the receiving layer 17 formed on the upper surface of the light transmitting substrate 41 of the display plate 90. The film sheet 115 is made of a resin such as a polypropylene resin, a polyethylene resin, a polycarbonate resin, a nitrocellulose resin, a nitroflon resin, or an acrylic resin, and has a glossy and smooth surface. The resin forming the film sheet 115 is not limited to the above resins, and any other resin having a relatively high heat resistance can be selected. In addition, water-repellent resin,
For example, a fluorine resin is not preferable. The transparent film sheet 115 has a thickness in the range of 25 to 50 μm.

As described above, the film sheet 115 and the transfer paper 112 are superposed on the timepiece dial 90, and the transfer is performed by applying pressure with the pressing tool 113 while heating. The heating temperature and pressure are about 180 ° C. and 10 g / cm as described above.
It should be about ² , but it is better to set the pressurization time longer. For example, when the pressurizing time is set to 90 seconds, it is preferable to set the pressurizing time to about 100 to 110 seconds and to set a little longer.

By such a transfer method, the transfer paper 112
The dots by the sublimation land dye on the side penetrate into the film sheet 115, and further penetrate into the receiving layer 17. In this way, when the transfer sheet 112 is transferred to the film sheet 115 and further transferred to the receiving layer 17, the dye is well mixed and contained,
It is possible to prevent the generation of dot-like spots and obtain a very beautiful gold color of "usus gold".

In this transfer method, the thickness of the film sheet 115 has a great influence on the quality of the gold color tone. Therefore, as a result of various experiments, it was found that it is preferable to set the thickness of the film sheet 115 to 25 to 50 μm. If the thickness is less than 25 μm,
The uneven paper pattern of the transfer paper 112 reaches the receiving layer 17 and moves to the receiving layer 17. If it is thicker than 50 μm,
The dye remains in the film sheet 115, causing a problem that the gold color tone formed on the receiving layer 17 lacks sharpness. Therefore, it is most preferable to set the thickness of the film sheet 115 in the above range.

Further, by polishing the upper surface of the receiving layer 17 to finish it into a smooth surface, it is possible to transfer with a constant pressure, and uneven transfer color tone does not occur. Furthermore, since the smooth surface of the receiving layer 17 and the smooth film sheet 115 are in contact with each other, the smooth surface of the receiving layer 17 is maintained even after pressing, and a clean surface can be finished.

Next, the setting for obtaining the color tone of "us gold" will be described. Even in this case, the sublimation dye ink is used to transfer about 144
Printing is performed with dots having a size of 0 dpi. At this time, the printing area of the "yellow" dots is set to about 30%, the printing area of the "red" dots is set to about 5%, and the remaining white background area is set to about 65%. Distribute the dots evenly so that they do not overlap. Then, in the same way as in the case of the color tone described above, it is transferred from the transfer paper to the receiving layer by heating and pressing through the film sheet, and while preventing the generation of spots of dots, a beautiful gold tone of "us gold" is obtained. To get

Next, the setting for obtaining the color tone of "us red gold" will be described. Also in this case, the sublimable dye ink is used to transfer the ink onto the transfer paper with an inkjet printer.
Printing is performed with dots having a size of 40 dpi. At this time, the printing area of the "yellow" dots is set to about 39%, the printing area of the "red" dots is set to about 7%, and the remaining area of the own area is set to about 54%. Disperse evenly so that the "red" dots do not stack. Then, in the same way as in the case of the color tone mentioned above, it is transferred from the transfer paper to the receiving layer by heating and pressurizing it through the film sheet, and while preventing the generation of dot spots, a beautiful gold color of "us red gold" is obtained. obtain.

Next, the setting for obtaining the color tone of "red gold" will be described. Also in this case, the sublimation dye ink is used to transfer about 1440 to the transfer paper with the ink jet printer.
Printing is performed with dots having a size of dpi. At this time, the printing area of the "yellow" dots is set to about 49%, the printing area of the "red" dots is set to about 12%, and the remaining white background area is set to about 39%. Disperse evenly so that there are no dots or stacks. Then, in the same manner as in the case of the color tone described above, it is transferred from the transfer paper to the receiving layer by heating and pressing through the film sheet, and while preventing the generation of spots of dots, a beautiful gold tone of “red gold” is obtained. It has gained.

As described above, in order to adjust to "us gold", "us gold", "us gold" and "red gold", the total area of the "yellow" dot printing and the total of the "red" dot printing are adjusted. The ratio to the area is set to about 4 to 6: 1, and the total area of the "yellow" dot printing and the "red" are set.
Is set to be about 10 to 61% per unit area of the transfer paper. The color becomes reddish gold as it changes from "usus gold" to "red gold", but the mixing ratio of "red" does not increase and the amount of dye that permeates, that is, "yellow", increases redness. And increase the total area of "red". The setting from "usus gold" to "red gold" can be adjusted by increasing or decreasing the permeation amount rather than the color mixture ratio.

The transfer paper in the above-mentioned embodiment is "yellow".
By using sublimable dye inks of two colors, “red” and “red”, the dots of each color are evenly distributed so that they do not overlap, and the dots are mixed at the time of transfer through the film sheet. Will come out. For example, using an “orange” sublimable dye ink that is a mixture of two colors of “yellow” and “red” sublimable dye inks in a predetermined amount, transfer it to its own color transfer paper with an ink jet printer. It can be changed to perform dot printing.

Also in this case, the conditions such as heating and pressurizing at the time of transfer to the receiving layer and the thickness of the film sheet are set in the same manner as in the above-mentioned embodiment. Even in this case, by using the film sheet, the dots are mixed well, and it is possible to obtain a beautiful color without unevenness.

In each of the above embodiments, the receiving layer 1
7 is made of a paint in which a UV absorber is dispersed and mixed in a polyurethane resin to obtain light resistance. In addition to this, as shown in FIG. 11, a clear coating in which the UV absorber is dispersed is formed on the upper surface of the receiving layer 17. The transparent protective film 16 may be provided by printing or coating to obtain light resistance. In this case, the timepiece dial having excellent light resistance can be formed by polishing the upper surface of the clear coating to form a glossy smooth surface.

On the other hand, the transfer method using a film sheet is not limited to the method of interposing the film sheet 115 at the time of transferring the sublimable dye ink from the transfer paper 112 to the receiving layer 17 as described above. There is also a method of transferring to a receiving layer using a film sheet on which dye ink is transferred. Next, a transfer method using a transfer film sheet to which the sublimable dye ink is transferred in advance will be described.

As shown in FIG. 19, the transfer film sheet 121 to which the sublimable dye ink has been transferred in advance penetrates into the transparent film sheet 122 in a vaporized state of the sublimable dye ink under heat and pressure. Then, the color tone portion 123 toned by the sublimable dye ink is formed. As shown in FIG. 20, the transfer film sheet 121 has a transparent film sheet 122 on the mounting tool 111.
Is placed, and the transfer paper 112 on which dots are formed by printing with sublimable dye ink is placed thereon, and the transfer paper 11 is pressed by the pressing tool 113.
It is formed by pressing 2. The transfer of the sublimable dye ink from the transfer paper 112 to the film sheet 122 is performed by heating the film sheet 122 to a temperature near the softening point of the resin component thereof, as in the above-described embodiment.
It is performed by pressurizing 2 with a constant pressure. At this time, the sublimable dye ink printed on the transfer paper 112 is vaporized, penetrates into the film sheet 122, and penetrates the color tone portion 123.
To form. The heating and pressurizing is performed on the film sheet 122.
It is necessary for the sublimation dye to penetrate deep inside, and weakens the intermolecular bond of the film sheet 122, and facilitates penetration of the vaporized sublimation dye into the intermolecular gap. After transferring and forming as described above, when the film sheet 122 is returned to room temperature, the transfer film sheet 121 on which the color tone portion 123 of the sublimable dye shown in FIG. 19 is formed is completed. In the transfer film sheet 121 that has returned to room temperature in this way, the intermolecular bond has returned to a strong state, so that the sublimable dye forming the color tone portion 123 cannot easily escape.

The material and thickness of the transfer film sheet 121 are the same as those of the film sheet 115 in the above-described embodiment.
Is the same as. The transfer paper 112 is also the same as that of the above-described embodiment.

Next, a method of transferring the sublimable dye ink to the receiving layer using the transfer film sheet 121 will be described with reference to FIG.
It will be described based on. 21 (a) is before transfer, and FIG.
FIG. 6B is a sectional view showing a state after transfer. Figure 21

Pressurize at 13. The transfer conditions such as heating temperature and pressure are set in the same manner as in the above embodiment.

According to this transfer method, the vaporized sublimable dye forming the color tone portion 123 of the transfer film sheet 121 penetrates into the receiving layer 17, and the same color tone as the color tone portion 123 formed on the transfer film sheet 121 is received. It is incorporated into layer 17. At that time, as in the above-described embodiment, the sublimable dye is well mixed, and dot-like spots do not occur.

As described above, if the transfer film sheet 121 in which the sublimation dye ink is permeated is prepared in advance, the gold tone can be transferred to the dial plate for the gold tone timepiece as needed and when necessary. . In particular, the transfer film sheet 121
Unlike the transfer paper 112, the sublimable dye ink does not vaporize and escape with the passage of time, and can be stocked for a long time. Also, film sheet 1
By mixing an ultraviolet absorber or the like in 22, it is possible to prevent the sublimation dye ink from being deteriorated by ultraviolet rays.

In the present embodiment, the example in which the receiving layer is provided on the light transmitting substrate has been described. However, as shown in FIG. 8, the light transmitting substrate 11 containing the ultraviolet absorber 13 has a gold color tone. The same effect can be obtained also in the timepiece dial 70 having the image 44 formed by transferring the image. As shown in FIG. 9, the transparent protective film 16 containing the ultraviolet absorber 23 is provided on the upper surface of the light transmissive substrate 31 on which the image 44 is formed, and the same effect can be obtained in the timepiece dial 80. I can.
