ものである。BACKGROUND OF THE INVENTION The present invention is applied to a varnish such as a light-transmitting paint or ink, which is dispersed and applied, or mixed with a light-transmitting synthetic resin material to form a sheet, a plate or the like. By extrusion molding into the shape, on the surface or inside of various required solids, one color selected appropriately such as red, orange, yellow, green, blue, indigo, purple according to the color of each powder when exposed to external light or A chromatic color for mixing paints or molding resin materials that can obtain a molded product with a painted surface or molded surface that emits independent reflected light such as constellations with multiple colors. It relates to a glittering powder.

Description of the Related Art Conventionally, gold foil powder, silver foil powder, aluminum foil powder and the like have been generally known as a mixed powder material for coating which emits reflected light of this kind. Further, it is also known that thin plate-like powder such as mica or glass flakes is plated with metal.

できないものであった。However, in the case of such a metal foil powder or a metal-plated powder,
Only the metallic light of the powder itself can be obtained, and chromatic light of various colors as described above cannot be obtained.

であった。Therefore, in the case of using such a conventional foil-like powder having metallic luster, the paint varnish is colored with a dye or a transparent pigment of a desired color in order to obtain a brilliant aesthetic appearance of chromatic color. I had no choice but to color it.

解決することはできないものであった。In this case, however, incident light is absorbed by the mixed dyes and pigments, and it also hinders the external transmission of reflected light, so that the reflectance of reflected light is lowered and the glittering property is lowered. It is impossible to solve the problem that it has a problem and that only the same color as that of the dye or pigment mixed with the bright color can be obtained.

る。Therefore, the object of the present invention is to obtain a completely new chromatic color light excellent in brilliance which cannot be obtained by the conventional means, and to improve the aesthetic appearance on the coated surface or the molding surface. In particular, when receiving direct light such as sunlight or headlights of automobiles, it is possible to form a painted surface or a molding surface that emits independent light such as a deep constellation in a submerged state. Another object of the present invention is to provide a powder having excellent brilliance, which emits chromatic light of any one selected color or plural colors selected from the chromatic light of seven colors.

書参照）As a powder capable of exhibiting such an excellent effect, the present inventors formed a transparent and smooth thin film of titanium dioxide on the surface of a flat fine powder having a metallic luster. I have already developed and proposed what I did. (For example, refer to the specification of Japanese Patent Application No. 4-209683)

である。The present invention utilizes the titanium dioxide film described in the prior invention, and by alternately laminating the titanium dioxide film and the silicon dioxide film, the saturation of the chromatic color in the powder is further strengthened and further enhanced. We are going to propose here a powder that emits excellent bright chromatic light.

Two or more six layers of transparent and smooth titanium dioxide thin films and transparent and smooth silicon dioxide thin films are alternately formed on the surface of the fine powder.

As for the silicon dioxide film (hereinafter referred to as “silicon oxide film” except for the examples), any one of the base materials may be coated first.
Similarly, the outermost layer may be any film, but a silicon oxide film is preferable. The number of layers of the film is preferably from two to six, and even if seven or more layers are laminated, it is difficult to improve the optical characteristics (saturation / brightness) of the powder.

とができる。The film thickness of each layer is adjusted according to the desired color of the glitter. As a general rule, each film thickness is set to be a refractive index of the film × geometrical thickness = a quarter thickness of the center wavelength of the chromatic light to be obtained, or an integral multiple thereof. However, it is extremely difficult to measure the laminated film thickness. However, regarding that the laminated film is formed by alternately laminating titanium oxide and silicon oxide, the surface of the powder subjected to the laminating process is subjected to surface analysis by Auger electron spectrum (AES) while performing sputtering with argon gas. It can be confirmed by doing.

な状態で得られるようにしたものである。The external light incident on the powder is reflected light at the surface of the outermost layer, reflected light at the interface between the surface of the base material and the film of the first layer, and reflected light at the interface between the films. And will be visible. Therefore, by utilizing the principle that the reflected light of a specific wavelength is particularly enhanced by adjusting the film thickness of each coating layer according to the wavelength of the specific chromatic color light as described above. That is, the present invention positively utilizes this principle, alternately stacks a titanium oxide film and a silicon oxide film, and specifies the respective film thicknesses, so that the red and yellow films corresponding to the film thicknesses can be obtained.・ It is possible to strengthen the hue of the reflected light of visible light such as green, blue, indigo, and purple for each layer.
Moreover, by selectively using a fine powder having a metallic luster as a base material, chromatic color reflected light can be obtained in a more vivid state.

なる。On the other hand, when the fine powder to be the base material has a high visible light transmittance, the visible light that has passed through the titanium oxide film or the silicon oxide film passes through the base material and its rear side. Since the reflected light reflected by (2) overlaps the above-mentioned reflected light on the powder surface side and causes unfavorable interference and weakens the specific color, it becomes difficult to emphasize the specific chromatic color.

Even though it is a fine powder, each powder itself has a flat plate shape, and has a wide light reflecting surface, which is selectively used.

Flakes and mica are suitable. However, the powder material is not particularly limited, and may be a flat plate whose surface is a mirror surface, which is easy to form a mirror surface, or which is easy to form a titanium oxide film or a silicon oxide film. Any surface may be used as long as it reflects most of visible light.

い。The particle size of the base material (size of the flat surface portion) is preferably in the range of 5 μm to 200 μm, and particularly preferably in the range of 10 μm to 150 μm. 5
If it is smaller than μm, the brightness of light becomes small and it becomes inconspicuous, and if it is larger than 200 μm, it tends to cause unevenness on the coating film or molded product surface when compounded with paint or synthetic resin, and when mixed with paint. However, there is a problem in that it is likely to settle to the bottom of the container or the device during storage or during painting work, and the nozzle of the spray gun is easily clogged, making spray painting difficult.

With a wide reflective surface, light can be reflected, and powder with high light brightness can be obtained.

It is possible to form a painted surface that emits independent light in a scattered manner, such as a constellation with a brilliant and highly saturated chromatic color corresponding to the color of. In addition, by combining the color of the solid to be coated with the reflected light color of the powder, and also by using several kinds of powders having different reflected light colors in combination, or by coloring the varnish, It has a remarkable effect that a coated surface having a different aesthetic appearance can be obtained.

するものである。The glittering powder of the present invention is used by mixing it with a synthetic resin molding material having a relatively high light-transmitting property, whereby a chromatic color similar to that described above, a vivid and highly saturated constellation is provided. It also has a remarkable effect that it is possible to obtain a resin molded product which is extruded and molded into a sheet-shaped, plate-shaped or other desired shape by emitting such a peculiar chromatic light in a scattered manner.
