2. Description of the Related Art A tubular body is coated with a surface to smooth it, an interference thin film is formed on the surface, and light interference is caused by the interference thin film under the condition that light rays are incident, thereby producing a color. It is disclosed in Japanese Unexamined Patent Publication No. Hei 7-31337.

[0003]

However, although an interference thin film is formed on a reel by this method although it is different from a tubular body, the color development can be observed only when an eye is directed to a certain direction in relation to an incident light beam. , And color development due to interference generally cannot be visually recognized from an appropriate position. In this case, the effect of coloring cannot be received.

[0004] Therefore, the present invention provides color development by light interference,
It is an object of the present invention to provide an article having an interference coating which is not limited to a specific direction and can be visually recognized from various directions.

[0005]

SUMMARY OF THE INVENTION In view of the above object, according to the present invention, there is provided a method according to claim 1, wherein a minute uneven surface for reflecting light is formed on the surface of the article, and a thickness capable of causing light interference on the uneven surface. The gist of the present invention is to form a transparent layer having a thickness different from that of the transparent layer and a thickness capable of causing light interference on the smooth surface. The term “transparent” in this specification includes not only completely transparent but also transparent. Further, according to claim 2, a layer in which a number of fine metallic pieces are dispersed in the transparent layer is formed on the surface of the article, and a transparent film having a thickness capable of causing light interference by other materials on the layer. The gist is to form

[0006] In the former, the light is reflected on the outer surface of the transparent coating which can cause light interference, and also reflected at the interface between the transparent coating and the transparent layer which can cause light interference. The light is reflected even at the boundary with the minute uneven surface of the article, and color is generated by the complex interference of the reflected light at these three places. Due to the presence of these minute irregularities that reflect light in random directions, coloring can be visually recognized not only from a specific direction but also from various directions. In the latter, the light is reflected on the outer surface of the transparent film that can cause light interference, and is reflected on the interface between the transparent film and a layer in which a large number of minute metallic pieces are dispersed.
The light is also reflected by minute metallic pieces in the layer, and the color is developed by the complex interference of the reflected light at these three places. Due to the presence of such a large number of minute metallic pieces that reflect light in random directions, coloring can be visually recognized not only from a specific direction but also from various directions. It was confirmed in an experiment that the coloring was visually recognized from the above various directions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments shown in the accompanying drawings. 1 to 5
FIG. 2 is an enlarged sectional view of the surface of the reel as an enlarged sectional view of an example of the form of the surface of the article having the interference coating according to the present invention. The surface of the article main body 10 made of synthetic resin, fiber reinforced synthetic resin, ceramics, or the like is formed in a rough surface (finished state with about two or three triangular symbols), and an opaque metal film 12 is formed on the rough surface S4. Then, a transparent layer 14 having an average thickness of about several microns is applied so as to fill and smooth the minute uneven surface S3. Further, a thin transparent film 16 having a thickness of about several thousand angstroms is formed on the surface S2 to have a substantially uniform thickness. In the case of molding with a mold, the rough surface can be obtained by molding the surface of the mold into a textured surface, or by subjecting the molded article body to shot blasting or barrel treatment.

The metal film 12 is an opaque light reflection film made of aluminum, chrome, nickel, gold, zinc or the like. The transparent layer 14 forms a smooth surface S2 using a transparent paint such as a UV paint (ultraviolet paint). This UV paint has an excellent surface leveling effect as compared with the hot-dry paint. The thin transparent coating 16 is similar to the interference coating of optical glass, and uses aluminum oxide (Al) as an oxide.
₂ O ₃ ), titanium oxide (TiO ₂ ), silicon monoxide (Si
O), silicon dioxide (SiO ₂ ), magnesium oxide (M
gO), chromium oxide (Cr ₂ O ₃ ), and the like by a covalent bond such as zinc sulfide (ZnS), lithium fluoride (Li)
F), magnesium fluoride (MgF ₂ ), calcium fluoride (CaF ₂ ), sodium fluoride (NaF) and the like.

In this structure, the light illuminating the reel is directed to the surface S
1 and partially transmits through the transparent coating 16 and also reflects on the surface S2, and further transmits through the transparent layer 14 and reflects on the surface S3 in a direction corresponding to the rough surface.
In indoors or in the natural world, light is radiated to the reel from various directions due to reflection or the like, and the reflected light of the above three places on the surface interferes with each other, resulting in color development, and not only in a specific direction but also in various directions. Experiments have confirmed that they can be seen from the direction.

When the transparent layer 14 is not provided, the thin transparent film 16 also becomes rough along the surface S3, and the color formed as a result of interference by the reflected light on the outer and inner surfaces of the transparent film. Is visible from various directions,
Although it is difficult to visually recognize it because of its high brightness, it has a high brightness as compared with the case without the transparent layer 14 because the surface S2 of the one provided with the slightly thick transparent layer 14 as in the present invention has a smooth surface S2. It was easy to recognize visually and it was confirmed that glossy color was formed. Coloring can be obtained even when the thickness of the transparent film 16 is changed by smoothly waving the surface S1 or S2. Further, the transparent coating 16
Even if a protective clear layer having a thickness of about 10 to 30 microns is formed on the surface, the state of color development is almost unchanged and can be visually recognized. The material of the protective clear layer may be the same as that of the transparent layer 14.

In FIG. 2, the article main body 10 is formed of metal, and the surface S4 is formed in a rough surface. The rough surface is formed in the same manner as described above, but the opaque metal film 12 is not required as in the case of FIG. Others are the same as those in FIG.

FIG. 3 shows fine particles 1 on the surface of article body 10.
A coating 18 containing 8G is applied to form a rough surface S4 ', an opaque metal film 12 similar to that shown in FIG. 1 is formed thereon, and a transparent layer 14 and a thin transparent The coating 16 is formed in the same manner as in FIG. Light is on the surface S1, S
2, reflected at S3. The minute particles 18G are inorganic particles or organic particles of about 1 micron or more.

FIG. 4 shows a layer 2 in which a large number of fine metallic pieces 20M are mixed in a transparent synthetic resin on the surface of the article body 10.
0 (thickness of about several microns to several tens of microns, for example, 10
(Thickness on the order of microns), and a thin transparent film 16 having a substantially uniform thickness similar to that described above is formed thereon. The transparent synthetic resin of the layer 20 may be the same material as the transparent layer 14 described above, or another material. The reflection of light in this case is
In addition to the surfaces S1 and S2, the light is reflected on the surface of the metallic piece 20M, and as a result of these interference with each other, the color develops. Since the metallic pieces 20M are oriented in various directions, colors can be visually recognized from various directions as in the case of FIGS.
In addition, since the surfaces S1 and S2 are smooth, a color having high brilliancy is exhibited.

FIG. 5 shows that when the article main body 10 'is formed by injection molding of a transparent synthetic resin, a minute metallic piece 20M is mixed with the whole and molded, or as shown in FIG. It may be molded by mixing only in the portion 20 '. A thin transparent film 16 of about 1 micron having a substantially uniform thickness similar to that described above is formed thereon. Also in this case, the light is reflected on the surfaces S1 and S2 and the surface of the metallic piece 20M, and as a result of these interference with each other, the color develops. Metallic pieces 20
Since M is oriented in various directions, colors can be visually recognized from various directions as in the case of FIGS. 1 to 3. In addition, since the surfaces S1 and S2 are smooth, a color having high brilliancy is exhibited.

In the above, the reel is taken as an example of the article.
As described above, the present invention can be applied to other fishing supplies and other articles.

[0016]

As is apparent from the above description, according to the present invention, the presence or absence of a fine uneven surface reflecting light on the surface of an article, or a transparent layer in which a large number of minute metallic pieces are dispersed, is achieved. Color development due to mutual light interference combined with light reflected on the upper two reflecting surfaces can be visually recognized from various directions. That is, the decoration effect can be enhanced regardless of the direction of the article or the position of the person.
