Although it shows a clear color, as time passes, the zinc sulfide and the silver plating 12 (Ag) of the phosphorescent 15 constituting the color phosphorescent 14
It reacts through clear paint 13 and silver plating 1
2 is discolored and blackened, so that there is a disadvantage that the color of the color light storage 14 appears discolored.

Further, the fluorescent pigment 16 constituting the color light storage 14 is susceptible to ultraviolet rays, and has a disadvantage that the color fades with the passage of time and the sharpness is lost.

[0006]

In order to solve the above-mentioned problems, the present invention provides an organic or inorganic film which is silver-plated on the upper surface of a substrate, has denseness, does not have air permeability, and does not react with phosphorescence. After baking or coating a white paint or forming a white metal such as rhodium or platinum by evaporation or plating, a phosphorescent light is formed by printing or painting, and at least one type of translucent color film is formed at least in part. It was done.

In the above structure, a translucent color film is formed after clear coating is performed on the upper surface of the phosphorescent light.

Further, the present invention is characterized in that a transparent resin thin film layer is formed on the upper surface of the translucent color film by matte coating or by coating a transparent resin and polishing by lapping.

[0009]

According to the present invention, silver plating (A
g) On top, it is dense, has no air permeability, and luminesces (ZnS)
After forming an organic or inorganic coating that does not react with
S), silver plating (Ag) and phosphorescence (Zn)
No reaction with S) occurs, and discoloration of silver plating (Ag) can be prevented.

In addition, since the translucent color film is formed on the phosphorescent light, the phosphorescent light is not affected by the ultraviolet light and the color of the translucent color film can be clearly seen by the phosphorescent light. However, the color is obtained by a translucent color film), and various colors of the translucent color film can be selected to form a variety of color patterns.

Further, by applying clear coating on the luminous surface, the unevenness of the luminous surface is smoothed, and when a translucent color film is formed thereon, the thickness of the translucent color film becomes uniform and there is no unevenness. It can produce clearer colors.

Further, by matte coating or forming a transparent resin thin film layer on the semi-transparent color film, the color of the semi-transparent color film is deepened and a more luxurious appearance is exhibited.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, taking a timepiece dial as an example.

FIG. 1 is a sectional view of a timepiece dial according to a first embodiment, FIG. 2 is a sectional view of a timepiece dial according to a second embodiment,
FIG. 3 is a plan view of a timepiece dial according to a third embodiment, and FIG. 4 is a sectional view taken along line AA of FIG.

In FIG. 1, reference numeral 1 denotes a dial board;
Is silver plating applied on the dial substrate 1. The silver plating 2 was selected because it is white and has a high reflectance, and the effect of the light storage described later can be made clearer. Of course, it is also possible to apply a plating of white nickel, rhodium, or the like. .

Reference numeral 3 denotes a baking coating of a white paint formed on the silver plating 2, and 4 denotes a phosphorescent (ZnS). The baking coating 3 is dense and has no air permeability, so that the silver plating 2 (A
g) and phosphorescence 4 (ZnS) do not occur, and no discoloration of the silver plating 2 (Ag) occurs.

The silver plating 2 having high reflectivity in white and the white baking coating 3 formed thereon has a synergistic effect,
The surface of the baked paint 3 becomes whiter and brighter,
Is more effectively increased in brightness.

Reference numeral 5 denotes a translucent color film formed by applying a translucent color paint on the upper surface of the luminous storage 4. Since it is translucent, a vivid color can be produced by the brightness of the luminous storage 4.

In this embodiment, a translucent color paint (mixture of a pigment and a clear lacquer) is applied to form the translucent color film 5, but the translucent color ink is used for screen printing or the like. It may be formed by printing.

On the other hand, if the concentration of the pigment in the translucent color paint or the translucent color ink is too high, the transparency is reduced, the brightness of the light storage 4 is cut, and the color vividness is reduced. It is desirable to adjust the pigment concentration in the range of 1/1000 to 3/1000.

Next, a second embodiment shown in FIG. 2 will be described.
The same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. In FIG. 2, reference numeral 6 denotes a clear coating applied to the upper surface of the light storage 4, and a semi-transparent color film is formed on the upper surface of the clear coating 6.

Normally, the phosphorescent light 4 is made of zinc sulfide (Zn) having a large particle size.
Due to the film of S), the surface of the light storage 4 has irregularities. When a translucent color film 5 is formed directly on this,
The thickness of the translucent color film 5 differs between the concave portion and the convex portion on the surface of the light storage 4, and when the color of the translucent color film 5 is viewed through the light storage 4, color unevenness may occur. The larger the area of the transparent color film is, the more noticeable the color unevenness is. When the clear coating 6 is applied to the upper surface of the phosphorescent light 4 as in this embodiment, the irregularities on the upper surface of the phosphorescent light 4 are smoothed by the clear coating 6, and the translucent color film 5 is formed on the clear coating 6. In addition, the thickness of the translucent color film 5 becomes uniform, and color unevenness does not occur.

Reference numeral 7 denotes a transparent resin thin film layer formed on the upper surface of the translucent color film 5, which is formed by coating a transparent resin and polishing it by lapping. By forming the transparent resin thin film layer 7 as described above, the color of the translucent color film has a gloss and a deeper appearance, giving a more luxurious appearance.

Next, a third embodiment will be described with reference to FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof is omitted. Reference numeral 8 denotes a window frame for the day of the week, formed of a translucent pink color film, and 9 represents a window frame of the date, formed of a green translucent color film.
As a manufacturing method, after forming the phosphorescent light 4, first, the window frame 8 is formed by screen printing with a pink translucent color ink and dried. Next, the window frame 9 is formed by screen printing with green translucent color ink and dried. In addition to the above, by selecting various colors of the translucent color ink and partially forming a translucent color film by screen printing or the like, a variety of patterns can be obtained.

[0025]

As described above, according to the present invention, after forming an organic or inorganic film which is dense and does not have air permeability and does not react with luminous storage on the silver plating, luminous storage is formed. And no discoloration of the silver plating can be prevented.

Further, since a desired color is obtained by forming a translucent color film on the phosphorescent light, the phosphorescent light is not affected by the ultraviolet rays and the desired color can be kept vivid forever. Various colors of the color film can be selected to form a variety of color patterns.

Further, by forming a translucent color film after clear coating on the upper surface of the phosphorescent light, the thickness of the translucent color film becomes uniform and a clear color without unevenness can be exhibited.

Further, by forming a matte coating or a transparent resin thin film layer on the semi-transparent color film, the color of the semi-transparent color film is deepened and gives a more luxurious appearance.
