BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal decorative plate used for a metal decorative panel such as a wall material in a car room of an elevator or a door in a hall, and a manufacturing method thereof.

[0002]

2. Description of the Related Art In a conventional metal decorative panel, after a rust preventive coating layer is formed on the surface of a metal plate, the surface of the metal plate substrate is hand-painted, a patterned sheet (PVC film, cloth, etc.) is pasted or screen printed. It had a pattern and a single color on it. Among the above, coloring by screen printing is common and many have been performed.

Further, as a coating method for a panel of this type, a conventional method is disclosed in, for example, JP-A-54-143453.
JP-A-61-263675 and JP-A-2-590.
The method disclosed in Japanese Patent No. 68 is known.

FIG. 16 is a sectional view of an example of a conventional metal decorative panel. In the figure, for example, a metal plate substrate 1 made of a steel plate
The anticorrosion layer 2 is provided on both surfaces of the. A base coating film layer 3 is provided on the rust preventive layer 2 on the surface of the panel, and an ink pattern layer 4 is partially provided thereon by screen printing. Then, a transparent protective film layer 5 is provided on the base coating layer 3 and the ink pattern layer 4.

Next, FIG. 17 is a process diagram for explaining a conventional method for manufacturing a metal decorative panel as shown in FIG. 16 and a method for manufacturing a screen plate accordingly, FIGS. 18 (a) to 18 (g).
FIGS. 19A to 19D are views showing the manner of each manufacturing process of the metal decorative panel of FIG. 17, and FIGS. 19A to 19D are views showing the manner of each manufacturing process of the screen plate of FIG.

First, a steel plate as shown in FIG. 18 (a), that is, a metal plate substrate 1 is prepared, and its corner portion is shown in FIG.
It cuts as shown in (b) (process S1), and also FIG.
Bending is performed as shown in (c) (S2) to obtain the shape of the metal decorative panel. Next, as shown in FIG. 18 (d), rust preventive coating is applied to the surface of the molded metal plate substrate 1 (S3), and this is dried (S4), and then a base coating (primer) (S5) and The background color coating (S6) is sequentially applied to form the rust preventive layer 2 and the base coating layer 3 of FIG.

After the base coating layer 3 is dried (S7), as shown in FIG. 18 (e), the screen plate 7 is set on the panel 6 after the background color coating and screen printing is performed (S8). . That is, the ink 8 on the screen plate 7 is spread over the entire screen plate 7 while moving the spatula 9 in the direction of the arrow.
The non-masked portion of the screen plate 7 is passed through the openings and transferred onto the panel 6.

As a result, as shown in FIG.
The panel 10 with the printed pattern is completed. And
After drying the ink 8 (S9), as shown in FIG. 18 (g), a clear protective film coating (S10) is applied to the panel 10,
If this is dried (S11), the protective film layer 5 will be formed and a metal decorative panel will be completed (S12).

On the other hand, in order to manufacture the screen plate 7, first, as shown in FIG. 19 (a), a masking photosensitive agent 13 is applied to the entire surface of the net cloth 12 attached to the screen plate frame 11 (S13). Next, the patterned film original 14 as shown in FIG. 19B is overlaid on the applied masking photosensitizer 13 and exposed by the light source 15 as shown in FIG. 19C (S14). And the pattern film original 1
Masking sensitizer 13 in the part irradiated with light through 4
19D, the masking portion 12a and the watermark portion 12b are formed on the net cloth 12, and the screen plate 7 is completed.

[0010]

In the conventional metal decorative panel as described above, since the ink pattern layer 4 is formed by screen printing, many processing steps are complicated and a lot of time is required for manufacturing. There was a problem that In particular, in the case of forming a pattern of a plurality of colors, the same number of screen plates 7 as the number of colors are required, and the number of steps is increased because of overcoating. Further, since it is necessary to manufacture the screen plate 7 every time the pattern is changed, there is a problem that the manufacturing cost becomes high. Furthermore, the ink pattern layer 4
However, since it is only applied almost uniformly on dots or a surface in which dots are connected, there is also a problem that the finished pattern surface is flat and has no depth, and the texture cannot be expressed. Furthermore, the resolution is 2-3 dots / m for screen printing.
There is also a problem that it is unsuitable as a metal decorative plate viewed in the vicinity because it is as rough as about m. Further, since the ink pattern layer 4 is formed by screen printing after bending the metal plate substrate 1, there is a problem that the ink pattern layer 4 cannot be formed on the side surface of the panel as shown in FIG. On the other hand, if the flat metal plate substrate 1 is subjected to the same screen printing and then bending, the ink pattern is broken, so that it is difficult to form the ink pattern on the side surface of the panel.

The present invention has been made to solve the above problems, and it is possible to reduce the manufacturing time, the manufacturing cost, and the finished pattern surface. A metal decorative plate that can have a texture and depth, can make the roughness of the pattern inconspicuous even when viewed closer, and can also provide a colored pattern on all sides of the metal decorative panel, The purpose is to obtain a manufacturing method thereof.
