DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a dichroic pear-shaped decorative material of gold and translucent colors, which can be applied to transparent plates such as glass plates and plastic plates, or plastic films, etc.
In normal cases, the dry film is transparent and the surface is fine grained, crepe-like, or rough by applying a paint and vacuum-depositing gold on the dry film to increase translucency. This article relates to a method for producing a dichroic pear-shaped decorative material with a golden color and a translucent color, which is finished in a pear-like finish that is golden and has a translucent color different from gold when light from a light source is transmitted through it. be.

Traditionally, wallboards, lighting fixtures, and other interior decoration items finished with a golden pear-like texture have been in high demand as they create a soft texture that gives a sense of security and peace, as well as a sense of luxury. It was a lot.

However, it is difficult to achieve a golden pear-like finish using a metal film unless the film is thick, and especially if expensive materials such as precious metals are used, the material cost alone will be expensive, and the product will not be suitable. The current situation is that the products are extremely expensive when sold on the market. Moreover, since the metal film is thick, it has low light transmittance and is unsuitable for lighting equipment, etc., and there has been a desire for an inexpensive product with light transmittance.

In addition, as a pattern finish using a thin metal film, a method for manufacturing a metal-deposited pattern sheet was proposed in Japanese Patent Publication No. 14745/1983, but in this method, a sheet with a continuous pattern punched out and a regular sheet are superimposed. Then, metal vapor deposition is performed on the side of the punched sheet, and the superimposed sheets are vapor-deposited at the same time, so it is effective for large patterns, etc.
This method was not possible when expressing a material such as pear-like texture on the surface of a plastic board or the like.

The present invention was developed in order to solve the above-mentioned drawbacks, and its gist is that it is a transparent material such as a glass plate, a plastic plate, a plastic film, etc., and is used for decorative objects that have a light source inside. A paint is applied to the surface of the dry film that is transparent and has a fine-grained, crepe-like, or rough surface, and then gold is applied to the dry film on the coated surface by a vacuum evaporation method. The purpose is to vapor-deposit a thin film with high translucency.

Below, we will explain the manufacturing method of the dichroic pear-shaped decorative material of gold and transparent color according to the present invention with reference to the drawings. The surface of a material 1 used for decorations, such as plastic film, which is transparent and has a light source 4 inside;
In the illustration, the dried film 2 is transparent on the inner surface, and the surface of the film 2 is made of resin such as acrylic resin or epoxy resin that creates a texture like a fine grained surface, a crepe-like surface, or a rough surface. Apply the paint.

Next, the transparent material 1 coated with this paint to form a film 2 is coated on the surface of the paint to a thickness of 1 micron in a vacuum evaporator (not shown) after the paint is dried. Below, the translucency actually increases.
Gold is vapor-deposited as a thin film 3 of 0.1 micron or less to produce a dichroic pear-shaped decorative material of gold and translucent colors.

As a result, when the light source 4 is not turned on, the interior of the decoration is dark, so the decorative material takes on a golden pear shape, and when the light source 4 is turned on, the light source 4
It becomes a translucent color when exposed to light.

With this decorative material, the surface of the transparent material 1 can be finished in a dichroic golden pear-like texture by simply applying paint and vacuum-depositing gold after drying. In vacuum deposition, the thin film 3 is deposited to a thickness of 0.1 micron or less, so
Even if expensive gold is used, it can be manufactured at low cost.

Moreover, since the pear-like thin film 3 is deposited on the transparent material 1, it has a pear-like finish even when viewed from the side opposite to the vapor-deposited surface.Furthermore, when used in the lighting equipment shown in FIG. 2, the above-mentioned As shown above, when the light source 4 is not turned on, the lighting fixture has a golden pear-like appearance when viewed from the surface, and when the light source 4 is turned on,
For example, when the film thickness is 0.0045 microns, it becomes a pale mauve color and transmits light, filling the room with soft light and creating a sense of luxury. In addition, 5 in the figure
is a transparent protective film.

Furthermore, when the above-mentioned decorative material is used, for example, in the instrument panel of a car, when the interior lights of the instrument panel are not turned on during the day, the company name, mark, or car name, etc. are expressed in gold, and the interior lights are turned on at night. Sometimes, if the back side is illuminated with an appropriate color, such as red or green, the gold part changes to each of the colors mentioned above, making it very beautiful and effective.

Examples of the method for manufacturing a dichroic pear-shaped decorative material of gold and transparent color according to the present invention will be described below.

Example 1 No. 5001 wrinkle clear varnish manufactured by Nippon Coating Co., Ltd., which is a crepe finish transparent paint manufactured using epoxy ester as the main raw material, was applied to a glass plate, and gold was applied to the surface of the resulting dry film to a thickness of 0.0045 microns. vacuum evaporated.

As a result, the cold image that conventional glass plates had was completely eliminated, and the glass plate had a soft, crepe-like feel and a luxurious golden color, and the transparent color was mauve.

Example 2 No. 2 manufactured by Nippon Coating Co., Ltd., which is a bead finishing paint manufactured using epoxy resin as the main raw material.
5008 bead clear varnish was applied to an acrylic plate, and gold with a thickness of 0.005 microns was deposited on the surface of the resulting dry film by vacuum evaporation.

As a result, the light and small image of conventional acrylic boards is eliminated, and the surface exhibits a golden fine grain surface, creating a luxurious and weighty feel, making it effective as a decorative board for interior decoration. It was mauve in color.

Example 3 50% of acrylic resin Acnoroid B-72 for paint manufactured by Rohm & Hass Co., Ltd. in the United States, xylol 49
%, aluminum octylate 1% was used to print on the surface of a plastic film by the silk screen method, and then gold was applied to the surface of the resulting dried film at a thickness of 0.005 microns under vacuum. It was deposited by vapor deposition.

As a result, the plastic film becomes a beautiful sheet with a golden rough surface and a mauve translucent color.When used as exterior parts for lighting equipment, it fills a room with soft light, and also makes lighting equipment look luxurious. It sets the mood.

Example 4 40% of the above acryloid B72, 10% of Ethocel 10CP (ethyl cellulose) manufactured by Dow Chemical Company, USA
%, 35% xylol and 15% N-butanol were used to print on the surface of a glass plate using the silk screen method, and gold was applied to the surface of the dried film to a thickness of 0.01 micron. It was deposited by vacuum evaporation.

As a result, one side of the glass plate has a golden rough surface, and the other side is just glass, so it can be used as a cupboard.
By using it as a wall panel for doll cases, etc., it makes the dolls look more luxurious, and if the light is shined from inside, a transparent color of mauve with a hint of green can be obtained. Furthermore, if it is used as a panel board for an audio product and gold is vapor-deposited only on the part where the text is displayed, only the text can be expressed in mauve by lighting up the internal light source 4.

Furthermore, the transparent color of gold varies slightly depending on the film thickness, and as the film thickness approaches 0.1 micron, the transparent color changes from mauve to green.

It should be noted that the examples of use shown in these embodiments are merely representative ones, and the present invention can be used in a wide variety of other fields.

As shown above, the method for producing the dichroic pear-shaped decorative material of gold and translucent color according to the present invention is to dry the surface of the transparent material used for decorations having a light source inside. The film is transparent, and the surface is fine-grained,
It is a simple method that involves applying a crepe-like or rough paint, letting it dry, and then depositing highly translucent gold on the dried film surface to form a thin metal film using a vacuum deposition method. A golden pear-like finish can be easily achieved, and a small amount of gold, which is a material for the thin film, is required, which saves on materials, so it can be provided at a low cost. And because it is a material used for decorations that have the light source, for example, in the case of lighting equipment, etc., when the light source is not turned on, it takes on a golden color, and when the light source is turned on, it takes on a golden color.
It has dichroism, exhibiting a transparent color ranging from mauve to green depending on the thickness of the gold coating, and the transmitted light creates a soft atmosphere, and it has a golden pear-like texture, making it popular among consumers. It is possible to provide products that have a soft texture and luxurious feel, giving a sense of relief and relaxation.
