DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. FIG. 1 is a sectional view of a metal decorative member according to Embodiment 1 of the present invention. In the figure, 1 is a base made of a metal plate such as a steel plate, 2 is a rust preventive layer applied to both sides of the base 1, and 3 is applied on the rust preventive layer 2 on the front side also as an adhesive layer. The base coloring layer 4 is a fibrous material sheet as a sheet member joined to the rust-preventing layer 2 via the base coloring layer 3, for example, paper. Reference numeral 5 denotes a translucent resin layer as a light-transmitting resin layer provided on the fibrous material sheet 4, and 6 denotes a fibrous material sheet 4 and a translucent resin by sublimation from between the fibrous material sheet 4 and the translucent resin layer 5. This is a sublimation-type coloring material that enters the layer 5 and forms a colored pattern.

Next, the manufacturing method will be described. FIG. 2 is a process chart showing a method for manufacturing the metal decorative member of FIG. When the metal decorative member shown in FIG. 1 is manufactured, first, both surfaces of the base material 1 are subjected to a rust prevention treatment, and a rust prevention layer 2 is formed (Step S1). On the other hand, the sublimation-type coloring material 6 is printed on the surface of the fiber material sheet 4 by a printer or the like connected to a computer (step S2). At this time, the sublimation-type coloring material 6 is attached to the fiber material sheet 4 by static electricity or the like in a non-sublimated state.

Thereafter, the fibrous material sheet 4 is bonded and attached on the rust-preventive layer 2 on the front side via the base coloring layer 3 (step S3). Subsequently, a translucent resin is applied on the fibrous material sheet 4 to form the translucent resin layer 5 (Step S4). Thereafter, the sublimation-type coloring material 6 is heated and sublimated (Step S5). As a result, the sublimation-type coloring material 6 enters the fiber material sheet 4 and the translucent resin layer 5 and forms a colored pattern. In addition, upon heating and sublimation of the sublimation-type coloring material 6,
The heating conditions, the thickness of the translucent resin layer 5, and the like are adjusted so that the sublimation-type coloring material 6 is not exposed on the surface of the translucent resin layer 5.

In such a metal decorative member, since the sublimation-type coloring material 6 is embossed in the translucent resin layer 5 from between the fiber material sheet 4 and the translucent resin layer 5, a colored pattern is formed. In addition to providing a three-dimensional effect, the colored pattern can be made pale and blurred, and the degree of freedom in pattern expression can be increased. In addition, the fiber material sheet 4
Is used as it is as a part of the metal decorative member, so that generation of dust is prevented, and it is environmentally friendly. Further, since the fibrous material sheet 4 such as paper is used as the sheet member, the sublimation type coloring material 6 can be easily printed, and the paint such as the base coloring layer 3 and the translucent resin layer 5 penetrates and adheres. Can be increased.

Embodiment 2 FIG. Next, FIG. 3 is a sectional view of a metal decorative member according to Embodiment 2 of the present invention. In this example, a transparent resin is applied on the fiber material sheet 4 to form a transparent resin layer 7 as a light-transmitting resin layer. Then, the sublimation-type coloring material 6 sublimates into the transparent resin layer 7 from the fiber material sheet 4 side to form a colored pattern. Other configurations and manufacturing steps are the same as those in the first embodiment.

In such a metal decorative member, since the colored pattern is formed such that the sublimation-type coloring material 6 protrudes from the fiber material sheet 4 side into the transparent resin layer 7, the pattern has a three-dimensional effect. Since the transparent resin layer 7 on the surface is transparent, the texture of the fibrous material sheet 4 can be given.

Embodiment 3 Next, FIG. 4 is a sectional view of a metal decorative member according to Embodiment 3 of the present invention. In this example, a resin film 8 is used as a sheet member, and the sublimation type coloring material 6 adhered on the resin film 8 is used.
Are penetrated into the resin film 8 and the translucent resin layer 5 by sublimation to form a colored pattern. Other configurations and manufacturing steps are the same as those in the first embodiment.

As described above, even when the resin film 8 is used as the sheet member, the colored pattern can be embossed in the translucent resin layer 5 and the colored pattern can be lightly blurred.
The degree of freedom in pattern expression can be increased, and generation of dust can be prevented. In addition, it is also possible to mix gold powder or other metal powder or the like in the transparent resin film 8 to have a unique texture.

Embodiment 4 In the third embodiment,
Although the translucent resin layer 5 was provided as the light transmitting resin layer, FIG.
As shown in FIG. 7, a transparent resin layer 7 may be provided, and the pattern can have a three-dimensional effect, and the resin film 8 can have a texture.

Embodiment 5 Next, FIG. 6 is a sectional view of a metal decorative member according to Embodiment 5 of the present invention. In this example, the base coloring layer 3 and the fiber material sheet 4 of the first embodiment are used.
Instead, the receiving layer 11 is provided on the rust-preventing layer 2, and the receiving layer 11 has a colored pattern formed by the sublimable coloring material 6. As the receiving layer 11, for example, a high-quality recording medium using porous alumina in which non-spherical alumina fine particles are oriented and many linear pores are formed is used.
Other configurations are the same as those of the first embodiment.

FIG. 7 is a process chart showing a method of manufacturing the metal decorative member of FIG. In the case of manufacturing the metal decorative member shown in FIG.
Is formed (step S1). Next, the receiving layer 11 is formed on the rust prevention layer 2 (Step S2). Thereafter, the sublimation-type coloring material 6 is directly printed (adhered) on the receiving layer 11 (step S3).

Next, a translucent resin is applied on the receiving layer 11 to form the translucent resin layer 5 (step S4).
Thereafter, the sublimation-type coloring material 6 is heated and sublimated (Step S).
5). Thereby, the sublimation-type coloring material 6 enters the receiving layer 11 and the translucent resin layer 5 and forms a colored pattern. In addition, when the sublimation-type coloring material 6 is heated and sublimated, the heating conditions, the thickness of the translucent resin layer 5, and the like are adjusted so that the sublimation-type coloring material 6 is not exposed on the surface of the translucent resin layer 5.

In such a metal decorative member, the receiving layer 11
Since the sublimation-type coloring material 6 is embossed in the translucent resin layer 5 from between the and the translucent resin layer 5 to form a colored pattern,
The colored pattern can be lightly blurred, and the degree of freedom in pattern expression can be increased. In addition, since the sublimation-type coloring material 6 is printed directly on the receiving layer 11, the generation of dust such as transfer paper is prevented and the environment is friendly to the global environment.

Embodiment 6 FIG. In the above example, the translucent resin layer 5 is shown as the light transmitting resin layer.
The transparent resin layer 7 may be provided as shown in FIG.

Further, in each of the above examples, the plate-shaped base material 1 is shown, but the present invention can be applied to base materials of other shapes such as corrugated, cylindrical, and spherical shapes.
