BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a decorative body for an accessory according to the present invention. FIG.
FIG. 2 and FIG. 2 show a first embodiment of the decorative body for accessories according to the present invention. In this embodiment, a decorative body 1 that is fixed to a frame of a personal accessory such as a pendant, an earring, or a ring.
Is composed of a transparent substrate 2 such as glass, plastic or the like. The transparent substrate 2 has a curved surface on its surface 3 and is matte-finished using a barrel or the like in order to produce a soothing color tone, or polished to have a gloss. On the other hand, the back surface 4 of the transparent base material 2 is formed in a substantially planar shape, and a line-shaped cut surface 5 is formed on this flat surface. The cut surfaces 5 extend radially from the center of the decorative body 1 to the periphery as shown in FIG. 2, and the cross-sectional shape of each cut surface 5 is a triangular shape as shown in FIG. is there. The planar shape of the transparent substrate 2 is variously set such as a circle, an ellipse, a rectangle, and a triangle. Also, the surface 3 of the transparent substrate 2 is not limited to a curved shape, but may be cut into a streak or other polyhedral shape. Needless to say, the cut surface of the back surface 4 is not limited to a streak. .

On the front surface 3 and the back surface 4 of the transparent substrate 2, multilayer vapor deposition films 6a and 6b are formed so as to reflect light in a desired wavelength range.
Is provided. The deposited films 6a and 6b are made of a lower oxide mainly composed of titanium oxide and silicon oxide having different refractive indices as a deposited material, and these deposited materials are alternately deposited to form a multilayer film of about 15 to 20 layers. Things. The thickness of the deposited film for each layer is calculated in advance so as to reflect light in a desired wavelength range, and is deposited to a predetermined thickness based on the calculated value. The vapor deposition films 6a and 6b formed on the front surface 3 and the rear surface 4 of the transparent substrate 2 may reflect light in the same wavelength range or may reflect light in different wavelength ranges. Evaporated film 6
When a and 6b have different properties, reflected lights having different wavelength ranges affect each other, and a unique emission color appears. In addition, as the deposition material, aluminum oxide, zirconia, yttrium oxide, or the like may be used in addition to the above titanium oxide or silicon oxide, and a deposition film may be formed using a combination of magnesium fluoride or zinc sulfide instead of a lower oxide. It is also possible.

FIG. 3 is a graph showing the reflection characteristics of the deposited layers formed as described above. This graph shows 55
Although a case where a high reflectance is obtained in a wavelength region around 0 nm is shown, the peak of the reflectance can be freely set depending on the type of the above-mentioned evaporation material, the number of layers to be overlapped, the thickness of the evaporation layer, and the like. When the vapor deposition films 6a and 6b strongly reflect light in a specific wavelength range, the decorative body 1 exhibits a specific hue. The vapor deposition film may be provided on one of the front surface 3 and the back surface 4 of the transparent substrate 2.

The back surface 4 side of the transparent substrate 2 is painted in an achromatic color such as white, gray or black. The coating film 7 is formed by naturally drying or baking an epoxy or acrylic paint. The coating film 7 blocks the transmission of light and has the effect of reflecting the light reaching the coating film 7. Therefore, even if the vapor deposited films 6a and 6b are the same, the color looks different due to the difference in the coating film 7.

Next, the light emission principle of the decorative body 1 having the above configuration will be described. As shown in FIG. 1, white light is incident on the surface 3 of the decorative body 1 from above. Due to the deposited film 6 a provided on the surface 3 of the transparent substrate 2,
First, light in a desired wavelength range is reflected. Next, the deposition film 6
The light that has passed through a travels inside the transparent substrate 2. And, by the vapor deposition film 6b provided on the back surface 4 of the transparent substrate 2,
Of the light, light in a desired wavelength range is reflected. The light reflected by the vapor deposition film 9b reaches the surface of the decorative body 1 and becomes light recognized from the outside. The deposited film 6b
The light reflected by the light source is reflected again by the vapor deposition film 6b facing the same, and the light may reach the surface of the decorative body by increasing the reflectance in some cases. As described above, the reflected light from the vapor deposition film 6a and the reflected light from the vapor deposition film 6b combine to make the decoration 1 shine.

Further, in this embodiment, since the striped cut surface 5 is formed on the back surface 4 of the transparent substrate 2, the deposited film 6b
Are also formed unevenly along the streaks of the cut surface 5. Therefore, the reflected light from the vapor deposition film 6b appears as a pattern on the surface of the decorative body 1 as a pattern. In addition, when the viewing direction and viewing angle are changed, the wavelength of light that is strongly reflected shifts, and as a result, a variety of color patterns appear on the surface of the decorative body 1, and the user can enjoy the playable color effect that can be transformed. Can be. Furthermore, when the surface 3 of the transparent base material 2 is satin-finished and the vapor deposition film 6a is provided on the upper surface, the surface of the decorative body 1 exhibits a sober and high-grade hue, and can bring out calmness and texture. . On the other hand, when the surface 3 of the transparent substrate 2 is polished and the vapor deposition film 6b is provided on the polished surface, light can be reflected more strongly by the vapor deposition film 6a, and a bright color can be enjoyed.

FIG. 4 shows the light reflection effect of the coating film 7 provided on the back surface 4 of the transparent substrate 2. The light transmitted through the transparent substrate 2 is divided into light that reflects the deposited film 6b provided on the back surface 4 of the transparent substrate 2 and light that is transmitted through the deposited film 6b. When the black coating film 7 is provided (FIG. 4A), the light transmitted through the deposition film 6b is absorbed by the coating film 7 without being reflected. Therefore, of the light transmitted through the transparent substrate 2, only the light in the desired wavelength range is reflected by the deposited film 6b. Further, since the transmission of light from below is blocked by the coating film 7, the light reflected by the vapor deposition film 6a and the light reflected by the vapor deposition film 6b are eventually emitted from the decorative body 1 as shown in FIG. Only appears. Therefore, by providing the black coating film 7, only the light that reflects the deposition films 6 a and 6 b is reflected from the decorative body 1, and a deep hue can be exhibited.

On the other hand, when the white coating film 7 is provided on the back surface 4 of the transparent substrate 2 (FIG. 4B), most of the light transmitted through the vapor deposition film 6b is reflected by the coating film 7. That is, of the light transmitted through the transparent substrate 2, the light reflected by the deposition film 6b and the light reflected by the coating film 7 appear together. In general, since the amount of light is larger than the amount of light, the light transmitted through the deposition film 6b and reflected by the coating film 7 is easily seen. Therefore, in this case, since much of the light in the wavelength range that passes through the vapor-deposited film 6b is reflected, unlike the black-based coating film, the overall color tone is brighter than the black coating film 7. The gray-based coating film 7 has a hue intermediate between a black-based color and a white-based color, and the reflected wavelength ranges may affect each other, resulting in a complex hue. If the coating film 7 is a chromatic or metallic film having the same hue as the reflected light from the vapor deposition film 6, a deep hue cannot be obtained.

FIG. 5 and FIG. 6 show a second embodiment of the decorative body for accessories according to the present invention. In the decorative body 1 in this embodiment, the transparent substrate 2 is formed in a so-called diamond shape, the back side is protruded in a conical shape, and the brilliant cut surface 14 is formed entirely. Then, on the surface 3 side above the girdle 8, a multilayer deposited film 6 is formed.
a on the other hand, a multi-layer deposited film 6
b and a coating film 7 formed thereon.

Next, the light emitting principle of the second embodiment having the above configuration will be described. When white light is incident on the surface 3 of the decorative body 1 from above, first, light in a desired wavelength range of the white light is reflected by the deposited film 6a. next,
The light that has passed through the deposition film 6a travels inside the transparent substrate 2,
Of the light, light in a desired wavelength range is reflected by the deposited film 6b provided on the back surface 4 of the transparent substrate 2. In this embodiment, since the front surface 3 and the back surface 4 of the transparent substrate 2 are both brilliant cut, the light once reflected on the vapor deposition film 6b becomes the light reflected on the vapor deposition film 6b on the opposite surface again,
Appears from the decorative body 1. For this reason, reflectivity is increased,
A more vivid hue can be obtained. In the present embodiment, the surface 3 above the girdle 8 is also brilliant cut, but may be formed in a curved shape without providing a cut surface. Further, in the present invention, when cut surfaces are provided on both the front side and the back side of the transparent substrate 2, the cut surfaces are not limited to cuts of the same type, but include cuts of different types. is there.

FIGS. 7 and 8 show an example in which the ornamental body 1 according to the present invention is applied to earrings and rings. In the earring 11 illustrated in FIG. 7, after the decorative body 1 in the above-described first embodiment is fixed to the pedestal frame 9, this is fixed to the earring stopper 10, so that the earring 11 can be used. Further, in the ring 13 shown in FIG. 8, by fixing the decorative body 1 in the second embodiment to the ring frame 12, it can be used as a ring 13 that shines vividly like diamond. In addition,
The decorative body 1 is not limited to being used for the earring 11 and the ring 13, and can be applied to various accessories such as pendants, piercings, and brooches.

[0022]

As described above, according to the decorative body for ornaments according to the present invention, a transparent base material is used for the decorative body, and light of a desired wavelength range is applied to at least one of the front surface and the back surface of the transparent base material. The decorative body can exhibit a desired hue because of the provision of the multilayer vapor-deposited film that reflects light. In addition, by forming a plurality of cut surfaces on at least the back surface of the transparent base material, the color pattern due to the reflected light from the cut surface appears to be raised on the surface of the decorative body, and the color pattern due to the reflected light is seen. By changing the direction and viewing angle, the color pattern becomes rich and varied, and you can enjoy the playable color effect. Further
An achromatic paint film on the deposited film on the back side
In this way, the transmission of light is blocked, and
Hue.

[0023]

Further, by forming the surface of the transparent base material in a satin shape, the surface of the decorative body can be reflected in a bitter manner to give a high-quality hue. On the other hand, by polishing the surface of the transparent base material and providing the deposited film on the polished surface, light can be more strongly reflected.

Further, by forming a brilliant cut surface on the back surface of the transparent base material and providing a multilayer vapor-deposited film on this cut surface, the reflectance from the cut surface on the back surface side can be greatly increased. , A more vivid color pattern can be exhibited.

Further, by providing a vapor-deposited film that reflects light in different wavelength ranges on the front and back surfaces of the transparent substrate,
It is possible to obtain a unique emission color in which reflected lights having different wavelength ranges influence each other.
