BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a colored part according to the present invention. FIG. 1 is a sectional view of a timepiece dial according to a first embodiment of the present invention.

In FIG. 1, a timepiece dial 10 is formed of a brass plate having a small hole 11a for attaching a hand at the center thereof and two feet 11b for attaching a timepiece movement on the back surface. A dial substrate 11 and a color-colored receiving layer 12 provided on the upper surface of the dial substrate 11 are formed. And a letter 13 fixed to the upper part of the receiving layer 12 by adhesion. The dial board 11 is provided with a pattern such as a basis weight and a plating process.

The receiving layer 12 is formed by adding 100 parts by weight of a transparent polyurethane resin to a chemical formula.

Embedded image A coating composition containing 2.5 parts by weight of an ultraviolet absorber of 2- (3,5-di-t-butyl-2-human peroxyphenyl) benzotriazole which is formed to a thickness of approximately 20 μm by a printing method or the like. And the surface is finished to a smooth surface by polishing.

The binder forming the receiving layer 12 is not particularly limited to polyurethane resin, and various resins such as polyester and acrylic resin can be selected.

As an ultraviolet absorber, 2- (3,5-di-t-butyl-2-human peroxyphenyl) benzotriazole is an absorber having extremely excellent light fastness, and exhibits a pale yellow color in powder form. The compounding amount must be set in consideration of the light resistance performance and the color tone of the receiving layer. When the amount is too small, the light resistance is lowered. On the contrary, when the amount is too large, the light resistance is extremely improved, but on the contrary, the receiving layer is colored, and the color tone with the coloring color appears, and the original color does not appear. As a result of various experiments, the blending amount was about 0.
It was found that light resistance was obtained when the content was in the range of 5 to 10 parts by weight, and a color tone comparable to that obtained was obtained.

If the thickness of the receiving layer 12 is too small, the dye is soaked, and the dye comes off due to a temperature change or the like over a long period of time, causing a phenomenon of fading. From the experimental results, it was found that the thickness of the receiving layer 12 was sufficient if it was about 10 μm or more. The thicker one is not particularly limited. The thicker one is preferable because the deeper the dye can penetrate, the better. However, there is also a problem that the printing cost increases. Thick is about 8
A thickness of 0 μm is sufficient. The receiving layer 12 is colored with a sublimable dye.

The color coloring method is as follows: a colorant is immersed in a sublimable dye solution heated to about 110 ° C. for about 1 minute, washed and dried after immersion, and heated at about 180 ° C. under a pressure of about 4 kg / cm ² . Originally, the surface of the receiving layer 12 was colored by pressing with a pressing device.

When immersed in the sublimable dye solution, the depth of immersion of the dye into the receiving layer 12 is shallow, and the depth of immersion of the dye is increased by heating and pressurizing in a later step, so that the color tint is increased. Can be very long.

The sublimable dye solution is a solution in which a plastic sublimable dye having affinity for the dye is blended. In the present embodiment, a solution in which approximately 4 parts by weight of the sublimable dye is blended in 100 parts by weight of the polyester resin. is there. The solution is immersed and colored in a heated state, and the immersion time is appropriately set in consideration of the heating temperature of the solution, the concentration of coloring, and the like. It is. The color density hardly changes even if immersed for 3 minutes or more. There is the convenience that the coloring density can be freely adjusted by adjusting the immersion time.

The heating temperature of the dye solution is slightly different depending on the binder used. However, in the polyester resin of the present embodiment, if the temperature is set in the range of about 100 to 120 ° C., the coloring can be performed in the above-mentioned immersion time. Becomes If the temperature is low, coloring takes time, and if the temperature is high, coloring is performed quickly.

After coloring the receiving layer 12 in this way, washing and drying, and then heating the binder near the softening point of the binder forming the receiving layer 12 and applying pressure, the dye immersion depth It penetrates deeper. If the pressure is small, the penetration is shallow, and if it is large, the receiving layer 12 is deformed by compression. A pressure of about ⁴ kg / cm ² is sufficient.

The timepiece dial 10 having the above-mentioned structure was subjected to a sunshine weather meter test in a wet state for 100 hours. As a result, no deterioration such as fading was observed in the coloring color, and the timepiece dial 10 was very good in light resistance. Dial 10 was obtained.

By the way, it is known that a benzosilazole-based ultraviolet absorber absorbs up to a long wavelength region of ultraviolet light. Examples of the benzosilazole-based ultraviolet absorber include 2- (3,5-di-t-butyl-2-human peroxyphenyl) benzenesotriazole, represented by Chemical Formula 1 described above,

Embedded image 2- (3-t-butyl-5-methyl-2-human peroxyphenyl) -5-chlorobenzotriazole,

Embedded image , 2- (5-methyl-2-human peroxyphenyl) benzotriazole,

Embedded image 2- (3,5-di-t-butyl-2-human peroxyphenyl) -5-chlorobenzotriazole,

Embedded image And 2- (3,5-di-t-amyl-2-human peroxyphenyl) benzotriazole.

By using the above structure of the present embodiment, various experimental results show that the above-mentioned 1 and 2 show remarkable effects, and are sufficiently satisfactory for a 100-hour sunshine weather meter test in a wet state. There was found.

In the present embodiment, 2- (3,5-di-t-butyl)
A 2- (3-t-butyl-5-methyl-2-human-peroxyphenyl) -5-chlorobenzotriazole ultraviolet absorber was also used. Obtainable.

Further, the following are known as inorganic ultraviolet absorbers. (1) Ultrafine titanium oxide: transparent (slightly blue) weak in weather resistance. (2) Ultrafine zinc oxide: transparent, antibacterial, deodorant. (3) Ultra-fine iron oxide: reddish, deteriorates resin, and has difficulty in safety. (4) Ultra-fine cerium oxide, pale yellow.

However, transparency is firstly required because it is incorporated in the receiving layer to be colored. Ultrafine zinc oxide is most suitable as such. Furthermore, since it has antibacterial performance, it is also preferable in health. Although ultrafine titanium oxide is transparent, it has a slight bluish tint, and the color tone appears when the blending amount is increased or the coating film thickness is increased. In addition, although it has a high effect on ultraviolet absorption, it has other weaknesses in weather resistance and is unsuitable for long-term use.

From the above, as an ultraviolet absorber, 2-
(3,5-di-t-butyl-2-human peroxyphenyl) benzotriazole, 2
-(3-t-butyl-5-methyl-2-human peroxyphenyl) -5-chlorobenzenesotriazole and ultrafine zinc oxide were selected as the most suitable ones.
Similar effects can be obtained. The same effect can be obtained even if these are mixed.

Next, the color-colored timepiece dial having the above-mentioned structure is formed through the following steps. (A) In the base material forming step, a dial plate is formed by pressing a metal plate such as aluminum or brass, and the two feet are fixed to the lower surface side by welding, and then metal plating is performed by applying an asahi weight. Form a decorative pattern and perform corrosion resistance treatment.

(B) In the step of forming the receiving layer, 2- (3,5-di-t-butyl-2-human peroxyphenyl) benzotriazole 2- (3 -t-Butyl-5-methyl-2-human peroxyphenyl) -5-chlorobenzotriazole A coating layer containing at least one kind of ultrafine zinc oxide is used to form a receptor layer having a thickness of about 20 μm by printing or coating.

(C) The step of forming a smooth surface is performed by polishing the surface of the receiving layer.

(D) In the coloring step, the above-described sublimable dye solution is immersed in a heated state, for example, at about 100 to 120 ° C. when the binder is a polyester resin for a predetermined time, for example, about 1 to 3 minutes.

(E) In the washing step, the receiving layer is colored and taken out and washed. (F) In the pressurizing step, when the dye is heated to near the softening point temperature of the binder forming the receiving layer and pressurized, the dye penetrates deeper.

When the color is colored in the above-described steps, a timepiece dial plate having a color which has a dye deeply penetrating into the receptor layer and has remarkably improved light resistance to ultraviolet rays can be obtained.

FIG. 2 is a sectional view of a timepiece dial according to a second embodiment of the present invention. 2, a timepiece dial 20 is formed of a brass plate having a small hole 11a for attaching a pointer at the center thereof and two feet 11b for attaching a timepiece movement on the back surface. Substrate 11
In addition, a color-colored receiving layer 22 provided on the upper surface of the dial substrate 11 is formed. An ultraviolet absorbing layer 23 is formed on the upper surface of the receiving layer 22. And a letter 13 that is adhesively fixed to a part of the ultraviolet absorbing layer 23. The dial board 11 is provided with a pattern such as a basis weight and a plating process.

The receiving layer 22 is provided with 2- (3-t-butyl-5-methyl)
-2- Human peroxyphenyl) -5-chlorobenzotriazole is used by blending it with a polyurethane resin. The compounding amount is approximately 2.5 parts by weight, based on 100 parts by weight of the polyurethane resin, as in the first embodiment. The printing thickness is approximately 20 μm.

The surface of the receiving layer 22 is polished and smoothed, and immersed in a sublimable dye solution to be colored. Further, an ultraviolet absorbing layer 23 is laminated on the color-colored receiving layer 22. The ultraviolet absorbing layer 23 is obtained by blending approximately 1 part by weight of ultrafine zinc oxide with respect to 100 parts by weight of an acrylic resin to form a coating, and applying and forming the coating to a thickness of approximately 30 μm.

The ultrafine zinc oxide has an excellent function as an ultraviolet absorber and is transparent, so that it is suitable as a protective film of such a colored color. Furthermore, since it has antibacterial properties, it can be said that it is suitable for use in mobile watch parts and mobile phone parts.

In this embodiment, approximately 1 part by weight of ultrafine zinc oxide is blended. However, a sufficient ultraviolet absorbing effect can be obtained by blending approximately 0.5 to 1.5 parts by weight. When the surface of the ultraviolet absorbing layer 23 is polished smoothly, unevenness on the surface is eliminated and a very beautiful colored color is obtained.

In the present embodiment, as the ultraviolet absorber,
2- (3-t-butyl-5-methyl-2-humanperoxyphenyl) -5-chlorobenzotriazole was selected, which is the same as the 2- (3,5-diphenyl) selected in the first embodiment. t-Butyl-2-human peroxyphenyl) has a remarkable effect similar to that of pensotriazole.

As a result of a 200-hour sunshine weather meter test of the watch dial having the above configuration in a wet state, no change in the coloring color was observed, and a very excellent light resistance effect to ultraviolet light was obtained. . By laminating such two ultraviolet absorbing layers, a further dramatic effect can be obtained.

Next, the timepiece dial having the above structure is formed through the following steps. (A) substrate forming step, (b) receiving layer forming step, (c) smooth surface forming step, (d) coloring step, (e) washing step,
(F) The pressurizing step is the same as in the first embodiment described above, and the description is omitted. (G) In the step of forming the ultraviolet absorbing layer, approximately 1 part by weight of ultrafine zinc oxide is blended with 100 parts by weight of the acrylic resin to form a coating, and the ultraviolet absorbing layer is formed by printing or coating to a thickness of approximately 30 μm. .

The present invention is not limited to the above-mentioned timepiece dial, but can be similarly applied to a device having a display unit, a communication device, an office device or the like using a transfer image forming part. Further, the present invention can be similarly applied to various nameplates and various seal plates.
