Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to furnishings and crafts exhibiting a single color or multiple colors. The furniture and crafts referred to here are those made of metal, glass, ceramics, organic resin, etc. 2 Furniture, tableware, household decorations, body decorations, souvenirs, household electrical appliances and their parts, etc.

BACKGROUND ART A wide variety of furniture and crafts have been known that are monochromatic or multicolored. Broadly speaking, these furniture and crafts can be divided into those made by processing the surface of the material to create a color, and those made from metal.

Some materials, such as colored glass and ceramics, are colored themselves. Processing methods for coloring the surface like the former include applying resin paint (by printing, spraying, etc.) and wet plating.

There are various methods such as vacuum plating.

On the other hand, in the latter case, the material itself becomes colored by absorbing light of a specific wavelength in the visible region.

This method takes advantage of the fact that the remaining light is reflected.

In addition, in any type of coloration, if the reflectance of light on the surface of an object is not significantly dependent on wavelength in the visible region, the object will be white or silvery in color.

For items whose surfaces have been treated to give them color.

Similar to the coloration of the material itself, there are those that appear colored due to absorption and reflection of light, and those that appear colored due to the interference effect of a thin film on one surface, such as luster glass coated with metal resin salt. be.

However, conventional furniture and crafts have the following deficiencies. Things that exhibit color through the absorption and reflection of light on the surface of a material or processed layer do not change color depending on the viewing direction, and the same object can always exhibit the same color tone. For example, in aluminum, etching and plating can be combined to obtain a colored surface.

It merely exhibits a color characteristic of the metal species deposited on the surface. Chrome and nickel plating are typical examples of conventional wet plating of metals.

In this case, it only exhibits the silvery white color characteristic of chromium and nickel, but has no coloring effect. When organic resins such as plastics are coated with aluminum using vacuum plating, when the plastic is colorless and transparent, it becomes silver, and when the plastic is yellowish, it looks like gold through the plastic. However, unless you change the color of the plastic, the color is monotonous and does not change depending on the viewing direction.

When a thin film of metal resin salt is applied using a spray method or a dipping method, such as the raster method, coloration occurs due to the interference effect of light, but it is difficult to obtain a uniform film thickness, and therefore there is a lot of color unevenness. Furthermore, since the raster method used for glass requires a heat treatment process, it is unsuitable for surface processing of metals, plastics, etc., and has not been put to practical use.

The object of the invention is to provide a furniture/artwork which eliminates the above-mentioned drawbacks.

According to the present invention, it is possible to obtain a decorative effect with a high degree of chromaticity that exhibits monochrome or multicolor depending on the viewing direction, that is, furniture and crafts that are extremely excellent in aesthetic appearance.

As a result of intensive efforts, the present inventors have developed a light-transmitting film that absorbs little light in the visible wavelength region, particularly a dielectric thin film, and a metal or metal compound that absorbs light.

The above objective was achieved by combining other absorbent materials, ie, opaque materials.

The present invention will be described in detail below with reference to the nine drawings.

Example 1 Referring to FIG. 1, in this example a hemispherical iron paperweight is shown. The hemispherical surface of the paper weight is plated with chrome, and a dielectric thin film consisting of three layers shown in FIG. 2 is further applied on the chrome plating layer. In Fig. 2, 2 is titanium oxide (TiO2), 3 is silicon oxide (SiO□), and has a structure in which silicon oxide 3 is sandwiched between titanium oxide 2, and the lower titanium oxide 2 is in contact with the chromium plating layer. be placed in a state of The thickness of each layer varies depending on the location, but the average thickness of the hemispherical surface of titanium oxide 2 is approximately 2.5 mm, and the color tone varies depending on the location, and the color also changes depending on the viewing angle.

Embodiment 2 Referring to FIG. 6, this embodiment shows a case where the present invention is applied to a single-axis insert made of glass. - The holes other than the center hole of the shaft insertion are polished, so
- Each surface forming the shaft socket is smooth. Among these surfaces, the lower surface 4 is coated with a dielectric thin film and a chromium film consisting of five layers as shown in FIG. The color changes depending on the direction you look at it, and due to the reflection effect on the cut surface of the glass, it has a unique bluish tone unlike any other. In Figure 4, 5 is zirconium oxide (2r
0□) and the film thickness is about 6soX, 6 is magnesium fluoride (MgFJ, and the film thickness is about 95OA. 7 is a chromium film, and the thickness is about 50OA. The thickness of the chromium film is 50A.
If it is above, substantially the same optical effect can be obtained. In this example, a top layer of zirconium oxide is deposited on the surface of the glass, and a chromium film 7 forming a light-absorbing or opaque material forms the bottom of the uniaxial socket; will be facing the object on which it is to be placed.

Next, with reference to FIG. 5, a case will be described in which the paper weight according to Example 1 shown in FIG. 1 is manufactured by a vacuum evaporation method.

■ Wash the iron paperweight 1 whose surface is chromium-plated with an organic solution such as trichloride or alcohol to remove dirt on the surface.

■ Set the cleaned paper weight 1 in the holder 9 in the vacuum chamber 8.

■ Evacuate the inside of the vacuum chamber 8 to a pressure of 5 x 10 Torr or less.

■ The oxygen (02) partial pressure in vacuum chamber 8 is lX10 To
rr, and the evaporation substance (titanium oxide) in the evaporation source 10 is
Titanium oxide is vaporized by an electron gun 11 and deposited on the paperweight 1. The film thickness is measured using an optical film thickness meter 12, and when the average film thickness reaches 50 OA, the deposition is stopped.

- Reduce the inside of the vacuum chamber 8 to 5×10 Torr or less, put an evaporative substance (silicon oxide) into the evaporation source 10, vaporize it with the electron gun 11, and deposit silicon oxide on the titanium oxide thin film described above.
Vapor deposition is performed until the average film thickness becomes 70OA.

Furthermore, by repeating the above-mentioned operation (2), the three-layer thin film shown in FIG. 2 can be formed. By rotating the holder 9 during vapor deposition, a large number of paper weights 1 of the same color tone can be manufactured at the same time.

In the examples, a chromium-plated iron ball and a glass substrate were shown as materials to be coated with a dielectric thin film.

That is, it is also possible to form a dielectric thin film directly on an opaque substrate. In addition, opaque metals 9 with high light absorption properties can be used on the surfaces of not only metals but also glass, ceramics, plastics, etc.
For example, a substrate coated with aluminum, chromium, nickel, tin, etc.

Or metal oxides like chromium oxide.

By laminating a dielectric thin film that absorbs little light in the visible wavelength range on an opaque material, such as a substrate coated with metal nitrides or carbides such as iron, chromium, copper, titanium, or aluminum, or a mixture thereof. Also, similar to the embodiment, an excellent decorative effect can be obtained.

In Example 2, a transparent glass substrate on which a dielectric thin film was laminated was further coated with a light-absorbing material.

The case where an opaque chrome film is coated and the opaque chrome film is viewed through a dielectric thin film and a glass substrate is shown. In this case, the same decorative effect can be obtained by coating a thin film of a material made of metal oxide, nitride, carbide, or a mixture thereof that is light-absorbing and opaque in the visible region in place of the chromium film. Also, instead of a light-absorbing thin film.

Colored resin paint may be applied, or cloth, paper, plastic, etc. may be attached. There are two tones depending on which method you use.
You can choose it by taking into account saturation, durability, etc.

In both Examples 1 and 2, by utilizing the light absorption of the opaque material, it is possible to obtain furnishings and crafts that vary in nine tones.

In the example, TiO2-8i02 and Z
Although an example of an alternating multilayer film of r02-MgF2 has been shown9, for example, in Example 1, a beautiful decorative effect can be obtained even in the case of a single layer of TiO2 film. In addition to the dielectric materials mentioned above,
CaF2. ThF4. CeF3. A40g, S
in, Ta20B.

A substance that absorbs little light in the visible region, such as CeO2HZnS, can be used. Furthermore, indium oxide doped with tin,
The same effect as the dielectric layer can be expected by depositing a conductive and transparent material such as antimony-doped tin oxide. This is due to the fact that the above-mentioned conductive material has a high refractive index of about 2.

The film thickness and combination of these materials may be selected in consideration of the properties of the substrate and the desired decorative effect. Generally, when creating a multilayer film, a high refractive index material and a low refractive index material are combined.

High reflection can be obtained, and decorative effects with high color saturation can be expected.

As mentioned above, there are furniture and crafts according to the present invention.

It has an unprecedented decorative effect. In other words, it becomes a piece of furniture or craftwork that has a great decorative effect.
