Embodiments of the present invention will be described below with reference to the drawings. Example 1. 1 is a sectional view of a metal decorative panel according to a first embodiment of the present invention. In the figure, a flat metal material 1
A base paint layer 2 for rust prevention and base coloring is provided on the top. On the base paint layer 2, four transparent heat-sensitive adhesive layers 3a to 3d are sequentially stacked.

The heat-sensitive adhesive layer 3a has a colored pattern 4a formed by adhesion of a black colored toner.
Colored pattern 4b due to adhesion of yellow colored toner on b
However, the heat-sensitive adhesive layer 3c has a colored pattern 4c formed by adhesion of magenta colored toner, and the heat-sensitive adhesive layer 3d has a colored pattern 4d formed by adhesion of cyan colored toner. A protective film layer 5 made of a transparent paint is provided on the heat-sensitive adhesive layer 3d.

Next, a method for manufacturing the above metal decorative panel will be described. 2 is a process diagram showing a method for manufacturing the metal decorative panel of FIG. 1, and FIG. 3 is a schematic configuration diagram showing a manufacturing apparatus for manufacturing the metal decorative panel of FIG. First, an undercoat is applied to the metal material 1 to provide an undercoat paint layer 2 (step S11). When a stainless steel plate is used as the metal material 1, this base coating can be omitted.

After that, the metal material 1 is placed on the conveyor 6 and conveyed, and the base coating layer 2 is applied by the adhesive applying device 7.
The heat-sensitive adhesive 8 is applied on top to form the heat-sensitive adhesive layer 3a (step S12). This adhesive applying device 7

The conveyor 6 is driven by the conveyor driving machine 11, and the metal material 1 is conveyed on the conveyor 6 by this.

Next, a laser irradiation device 1 as a heating device
2 partially irradiates the heat-sensitive adhesive layer 3a with a laser beam (step S13). Applied heat-sensitive adhesive 8
Has almost no tackiness in a dry state, but tackiness occurs in a portion (adhesion dot portion) heated by the laser irradiation. A heating control device 13 is connected to the laser irradiation device 12. The heating control device 13 is also connected to the conveyor driving device 11 and controls the heating position by the laser irradiation device 12.

An image scanner 14 and a computer 15 are connected to the heating controller 13, and data of an image read by the image scanner 14 or an image created by the computer 15 is decomposed into four colors, and pattern data of each color is obtained. The laser irradiation device 12 is controlled accordingly. Therefore,
First, the first heat-sensitive adhesive layer 3a is irradiated with laser on a portion corresponding to black.

Thereafter, the toner coating device 16 coats the first color, that is, the black colored toner on the entire surface of the heat-sensitive adhesive layer 3a (step S14), whereby the heat-sensitive adhesive layer 3a is heated by laser irradiation. Colored toner adheres to the part. Next, the toner cleaning device 17 having a suction pump sucks the colored toner on the heat-sensitive adhesive layer 3a (step S15). As a result, the excess colored toner excluding the colored toner attached to the heat-sensitive adhesive layer 3a is removed from the heat-sensitive adhesive layer 3a, and the black colored pattern 4a remains on the heat-sensitive adhesive layer 3a.

Next, the metal material 1 is returned by the conveyor 6, and the remaining three colors are repeated from the step of applying the heat-sensitive adhesive to the step of cleaning the colored toner. Finally, top coating is applied by the clear coating device 18 (step S
16), the protective film layer 5 is formed on the uppermost layer.

As the heat-sensitive adhesive layers 3a to 3d,
For example, a polyamide-based or vinyl acetate-based hot-melt adhesive is used. In addition, since the colored toner can be colored by adhesion, various types such as an organic dye as well as an inorganic pigment and an organic pigment can be used.

In the metal decorative panel as described above, since the heat-sensitive adhesive layers 3a to 3d are used for the receiving layer of the colored toner, the color separation film, which is expensive and laborious to manufacture, for drawing the colored patterns 4a to 4d. It is not necessary to heat the heat-sensitive adhesive layers 3a to 3d directly. Therefore, the manufacturing is simple and the time is short, and the cost is reduced. Further, by providing the protective film layer 5 on the uppermost layer, the pattern can be made deep and the pattern is protected from external force and ultraviolet rays.

Further, the pattern data of the image scanner 14 and the computer 15 are color-separated by the heating control device 13 to directly control the laser irradiation device 12, so that a large screen (for example, 1 m wide × 3 m long) can be displayed. On the other hand, highly accurate pattern reproducibility can be obtained. In addition, by using translucent ink for the colored toner, the same 36
It is also possible to reproduce a full color image of 00 DPI (16.7 million colors).

Although the colored patterns 4a to 4d for four colors are overlapped in the first embodiment, the number of colors may be determined according to the pattern, and may be one color, for example. Further, although the laser irradiation device is shown as the heating device in the first embodiment, the heating device is not limited to this and may be the same as a thermal head used in a printer or the like.

Further, the specific configurations of the adhesive applying device 7, the toner applying device 16, the toner cleaning device 17, etc. are not limited to those in the first embodiment.
