DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view schematically showing a decorative product 11 in the present embodiment. As shown in FIG.
And a protective layer 13 provided on the base material 12. Further, the base material 12 includes a base material body 12a.
And the glittering coating layer 1 provided on the base body 12a
2b. In order to clearly show the configuration, in FIG. 1, the protective layer 13 and the bright coating layer 12b are shown.
Is exaggerated.

The material of the base body 12a is not particularly limited, and specific examples thereof include plastic, metal, glass and the like. Examples of the plastic used here include ABS resin, polyethylene terephthalate, polyvinyl chloride, polycarbonate, polyamide, polyphenylene ether, polyurethane, and polystyrene.

The brilliant coating layer 12b is formed of a brilliant paint such as a metallic paint mixed with flake-like metal powder (aluminum, copper, etc.). The thickness of the glittering coating layer 12b is preferably in the range of 0.1 to 25 μm, more preferably in the range of 1 to 15 μm, and 4 to 5 μm.
The range of μm is particularly preferred.

The protective layer 13 is formed of a clear paint. As the clear paint, a urethane paint, an epoxy paint, an acrylic paint, or the like can be used. The thickness of the protective layer 13 is preferably in the range of 4 to 40 μm, more preferably in the range of 4 to 20 μm, and particularly preferably around 10 μm. If it is less than 4 μm, sufficient durability cannot be obtained, and the surface of the substrate 12 cannot be sufficiently protected. Conversely, if it exceeds 40 μm, the adhesiveness to the substrate 12 may be reduced. Also, the protective layer 13
Is colored transparent or colored translucent, and this coloring is achieved by immersion in a dye bath. The type of dye used in this dye bath is not particularly limited, but disperse dyes such as azo dyes and anthraquinone dyes are preferred from the viewpoint of excellent coloring properties.

Next, the decorative product 1 configured as described above.
1 will be described. The production of the decorative product 11 is performed through the glitter coating layer forming step, the protective layer forming step, and the dyeing step in this order.

First, the glittering coating layer forming step is a step of forming a glittering coating layer 12b by applying a glittering paint on the base material body 12a.
2 are formed. Spray coating,
It is performed by a known method such as brush coating, roller coating, and soaking.

In the next protective layer forming step, the bright coating layer 12
This is a step of applying a clear paint on the substrate b, that is, on the base material 12, to form a colorless transparent or colorless translucent protective layer 13. The application of the clear coating is performed by a known method, similarly to the application of the glittering coating.

The subsequent dyeing step is a step of coloring the protective layer 13. This coloring is performed by immersing the substrate 12 provided with the colorless transparent or colorless translucent protective layer 13 in a dye bath, preferably a heated dye bath. For example, in the case of dyeing using a disperse dye, the dye bath contains a disperse dye and a surfactant, and 0.5 to 5 grams of the disperse dye and 5 to 20 surfactants per liter of the dye bath. Preferably, the composition contains milliliters. Examples of the surfactant include anionic, cationic, amphoteric or nonionic surfactants, and are appropriately selected from these and used. The bath temperature is preferably 50 to 95 ° C., and the dyeing time is preferably 5 seconds to 20 minutes.

According to the above-described embodiment, the following effects can be obtained. The colored transparent or colored translucent protective layer 13 formed on the substrate 12 is colored by immersion in a dye bath.
For this reason, the dye penetrates from the surface of the protective layer 13 and the penetration speed is the same at any position on the entire surface of the protective layer 13, so that the protective layer 13 is colored by the same thickness from the surface at any position. Is done. That is, the degree of coloring is uniform at any position on the entire surface of the protective layer 13. Therefore, even if the thickness of the protective layer 13 is not uniform, it is possible to obtain the decorative product 11 with extremely small color unevenness. Further, since there is no need to form the protective layer 13 to have a uniform thickness, the decorative product 11 as described above can be easily obtained.

By using a disperse dye, the protective layer 13 can be reliably colored. -Since the glittering coating layer 12b underneath is visible through the colored transparent or colored translucent protective layer 13, the glittering coating layer 12b is colored by the protective layer 13 instead of the glossiness of the glittering coating layer 12b. The decorative product 11 presents a gloss of a predetermined color tone. Therefore, by changing the color tone of the protective layer 13, or by changing the color tone of the glittering coating layer 12 b, or by changing both the color tones, changing the gloss exhibited by the decorative product 11 to a desired color tone. Can be.

The brilliant coating layer 12b is formed of a brilliant paint, and the brilliancy is imparted to the base 12, so that the base 12 with high brightness can be obtained. Further, by using a metallic paint as the glitter paint, the glitter coating layer 12b can exhibit metallic luster.

By making the protective layer 13 translucent, the appearance of the decorative product 11 can be made matt.
In particular, when it is matte and exhibits a silver color tone, an alumite-like appearance can be obtained.

By forming the protective layer 13 to a thickness of 4 to 40 μm, the function of protecting the base material 12 can be sufficiently exhibited.・ Dye bath is disperse dye 0.5 to 1 liter per dye bath.
By preparing so as to contain 5 grams and 5 to 20 milliliters of the surfactant, the coloring of the protective layer 13 can be made sure and efficient. In addition, bath temperature is 50-95
The dyeing bath is heated to a temperature of
By setting the time to seconds to 20 minutes, the coloring of the protective layer 13 can be surely and efficiently performed.

The above-described embodiment can be modified as follows. In the embodiment, the clear paint is applied on the base material 12 to form the protective layer 13. However, a transparent or translucent film material made of a synthetic resin such as polyester is adhered on the base material 12. Then, it may be used as the protective layer 13. The protective layer 13 made of a film material is the protective layer 13 made of a clear paint.
Since the smoothness of the surface can be easily obtained as compared with the above, coloring can be performed more uniformly.

In the embodiment, the glitter 12 is formed by forming the glitter coating layer 12b on the substrate 12a. However, a glitter material such as a metal film may be used for the glitter. The base material 12 may be provided with glittering properties by sticking on the base 12a.

When the base body 12a itself has a brilliant property, for example, when the base body 12a is made of metal, the brilliant coating layer 12b may be omitted. When the adhesiveness between the base material body 12a and the glittering coating layer 12b is weak, a primer layer made of a primer for improving the adhesiveness may be provided between the two.

The shape of the substrate 12 is not limited to a flat plate as shown in FIG. 1, but may be a complicated shape such as a curved surface. In this case, the protective layer 13
Although the thickness of the protective layer 13 is likely to be nonuniform, the coloring of the protective layer 13 can be performed uniformly without depending on the nonuniformity, so that the decorative product 11 with extremely small color unevenness can be obtained.

Next, the technical ideas that can be grasped from the above embodiment will be described below. The decorative product according to claim 1 or 2, wherein the protective layer is formed of a clear paint. With such a configuration, the protective layer can be easily formed even in the case of a substrate having a complicated shape such as a curved surface.
