JPH01198506A - Colored accessory made of imitate jewelry - Google Patents

Abstract

PURPOSE:To get an accessory made of imitate jewelry, which emits a beautiful color, by a method wherein the light, reflected from its surface is prevented and only the light partially absorbed through the interior of material is preferentially emitted outward. CONSTITUTION:The surface 2 of an accessory made of imitate jewelry is covered by a layer 4 of coating for preventing reflection, and a mirror 5 reflecting light is placed on the back side. The interior 6 of the accessory 1 is an artificial transparent body, such as plastics, glass, and imitation jewelry, and the brightness of its color is five and below by Munsel color system. Since the colored light emitted toward its surface through the transparent body is increased by reflecting mirror, the beauty of reflection and color is increased. Since the reflection of white light on its surface is also prevented by a lager 4 of coating for preventing reflection, it is possible to get their synergistic effect with each other.

Description

[Detailed description of the invention]

The present invention is an artificially constructed jewel-shaped colored ornament,
It provides more saturated colors than gemstones made from natural materials.

[Prior art]

Natural gemstone materials are expensive, but even if they could be obtained in large quantities at low cost, the color of gemstones is due to the absorption of a portion of the light rays when they pass through the interior of the gemstone. However, there are other gems. White rays that are not absorbed (not colored) are reflected from the surface of the There is no problem with white gemstones like diamonds, but problems arise with colored gemstones like rubies. That is, the light rays that pass through the inside of the gem and are emitted appear to shine as colored bright spots, and the light rays reflected from the surface appear to shine as white bright spots. This development is noticeable when the gemstone has high chroma and low brightness (e). For example, in the case of deep red, the brightness is about 3.5 in the Munsell color system, and the amount of light is 10% culm. The beautiful crimson color that emerges is obstructed by the light reflected from the white surface and loses its beauty. The presence of such interfering light rays due to surface reflected light (white light) has been thought to be an unavoidable phenomenon for colored gemstones processed from natural materials. Colored rays and white rays on gemstones
Until today, no one thought it strange that a seed ray existed and that both of them sparkled together.

[Issue to be solved]

In the field of ``jewels,'' those made from processed natural materials were considered high-quality, while those that were artificially imitated were considered low-class. If it were possible to create something artificially more beautiful than a product made from natural materials, there is a possibility that people would prefer that artificial product.

[Means to solve the problem]

By preventing light rays from reflecting from one surface, going against the long-held common sense that gemstones are sparkling, we prioritize only the partially absorbed (colored) rays that have passed through the interior of the material. By injecting it to the outside,
This makes it possible to emit extremely pure (highly saturated) colors. This emits a beautiful ``artificial'' ray that humans have never encountered before. The present invention is configured as follows. Namely. For a transparent body formed in a shape similar to a jewel, a mirror surface for reflection is formed on the surface that is not exposed to the surface (pedestal side), and the exposed surface is coated with an anti-reflection coating. It is located on the outer periphery and is composed of an artificial substance that has a color with a brightness of 5 or less.

[Example 1] In Figures 1 and 2, 1 is a jewel-shaped decoration, 2 is a surface exposed to the surface, 3 is a surface not exposed to the surface (pedestal side), and 0 surface side is reflective. The layer 4 covered with the protective coating layer 4 is a thin film, for example, one-fourth the wavelength of light, and the thickness is exaggerated in Figure 1. A mirror surface 5 that reflects light is provided on the back side. The configuration of the mirror surface is formed by a well-known method such as metal vapor deposition, sputtering, amalgam, etc. The interior 6 of the decorative body 1 is made of synthetic resin or glass, for example. It is an artificially created transparent body such as an artificial gemstone. The transparent body 6 is given a color with high saturation and low brightness. As for the coloring means, the transparent body itself may be a colored substance, or only the outer surface of 6 may be colored. Colors with high saturation and high brightness include crimson, deep blue, and purple, and in the Munsell color system, 0 color, which is a color with a brightness of 5 or less located on the outer periphery, is high saturation, and 4 is yellow, orange, and yellow-green. Colors with high brightness, such as colors, are not applicable. Colors such as red, blue, and purple that have a brightness of 5 or less (not bright). Brightness 5 is 20% brightness when white is 100%. Crimson, dark blue, dark purple, etc. are darker1
The brightness is about 0%. Since such an artificial transparent body cannot have a high refractive index like a diamond, it is not possible to rely solely on total reflection, and the amount of reflected light is increased by the single reflecting mirror 5. The amount of colored light fi (hereinafter referred to as colored light rays) that passes through the transparent body and emerges onto the surface increases due to the reflective mirror, and it overcomes the white light rays reflected from the surface, maintaining the beauty of the colors. do. Furthermore, by providing the antireflection coating layer 4, reflection of white light from the surface is also prevented. Both of these, that is, the increase in the amount of colored light rays due to the reflection kt5 and the prevention of white light rays due to the antireflection coating layer 4, mutually produce a synergistic effect. Furthermore, conveniently, the white light rays whose reflection is prevented by the surface are transmitted inside and reflected by the reflecting mirror 5. Since the light is emitted from the surface again, the amount of colored light increases accordingly, resulting in an increase in beauty.

[Embodiment 2] In the above embodiment, the transparent body 6 was coated with reflective W45. However, as long as the effect is maintained, it is not necessary to optically integrate the transparent body 6 and the reflecting mirror 5, and the reflecting mirror may be provided as an optically separate body. (not shown) or a back cover may be formed into a reflecting mirror.

[Example 3] It is easy to provide the transparent body 6 with a color, and there is no reason to avoid it, but as one embodiment, the transparent body 6 is not colored, is colorless, or does not have a sufficient color. Alternatively, the antireflection coating layer 4 may have a color, and the color may be located on the outer periphery in the Munsell color system and have a brightness of 5 or less. In each of the embodiments, the exposed side 2 of the transparent body 1 has a multi-faceted shape as shown in FIG. 1 and 2, a single surface as shown in FIG. Use well-known shapes used in jewelry and ornaments, such as those composed of eye-curved surfaces. The mirror surface provided on the non-exposed side may be multifaceted as shown in FIG. 1, 3, or may be a single mirror-like plane as shown in FIG. 5, or may be a curved surface as shown in FIG. 6, 3. It is often shaped like a well-known reflective surface, such as a surface with many irregularities. Further, throughout each embodiment, in order to prevent the anti-reflection coating layer from being charged with static electricity, it is recommended that the layer 4 and a support such as a pedestal (not shown) be electrically connected and grounded. It is advantageous if the coating layer 4 itself has antistatic properties. In addition to accessories such as pendants and brooches, it may also be used as a decorative item to add beauty to articles 1 used in other fields, such as stationery, personal items, and clothing.

【effect】

Compared to jewelry made from natural materials, it is possible to obtain jewel-like ornaments that emit beautiful colors that surpass them.
