点があった。2. Description of the Related Art Heretofore, noble metals such as gold and platinum have been provided with a pattern on the surface by engraving using a mold as seen in coins and medals. By the way, in recent years, with the popularization of precious metals, the handling units of gold, platinum and the like have become smaller, and trading in gram units has been made. However, such a small amount of precious metal formed into a coin or a medal or the like by press molding in a state of having a certain thickness does not have a good appearance because of its small shape, and is less effective as a souvenir or a gift. There was a drawback.

In this case, for example, when 1 g of gold is rolled to a thickness of 20 μm, it can be made into a thin plate having an area about the size of a business card, so that it looks good enough.
Since decorative patterns, characters, and the like can be easily provided, the present invention is also effective as a souvenir or a gift.

The noble metal composite plate 10 has a transparent resin film (protective film) 2 coated on both surfaces of a thin plate 1 made of a noble metal such as gold, silver, platinum or the like, or a noble metal alloy. The transparent resin films 3 are overlapped, and the whole is covered with a transparent transparent resin film 4 and integrated.

金属複合板全体が厚くなるという欠点もあった。However, the conventional noble metal composite plate 10 has a transparent resin film 4 as the outermost layer.
No precious metal is contained up to the end, and there is a region of only the transparent resin film 4 at the end of the precious metal composite plate, so that there is a disadvantage that the appearance is not good. Further, since the conventional noble metal composite plate is double-coated with the transparent resin films 2 and 4, not only the manufacturing process is complicated but also there is a disadvantage that the entire noble metal composite plate becomes thick.

じることになる。On the other hand, if the outermost layer is not covered with the transparent resin film 4, the noble metal thin plate 1 is exposed on the end face, and the noble metal is rubbed during handling to change the amount of the noble metal. This results in a disadvantage that the film is peeled off.

As schematically shown in FIG. 1, a gold card 20 as a noble metal composite plate of the present invention includes a noble metal thin plate (gold foil) 11,
Pictograms (including designs, letters, landscapes, pictures, etc.) are printed, and the protective films 12, 1 are pressed against both surfaces of the precious metal thin plate 11.

ーで所定長さごとに切断する方法であってもよい。A method of manufacturing such a gold card 20 will be described with reference to FIG. First, a gold foil 11 having a thin plate shape (for example, thickness: 15 μm, width: 50 mm) is manufactured by rolling. Then, both sides of the gold foil 11 are sandwiched between two strip-shaped protective films 12 and are adhesively coated with a heated roll. Thereby, the coated noble metal sheet 13 is obtained. Next, the coated precious metal thin plate 13 is punched one after another in a business card size at predetermined intervals in the width direction at a central portion in the width direction to mass-produce the gold card 20. Instead of punching, a method may be used in which the sheet is cut into a predetermined width by a slitter and then cut by a predetermined size cutter at a predetermined length.

Is performed by lowering one of the blades 15 from above the coated noble metal thin plate 13. At this time, the two blades 14,
The clearance d (the amount of separation between the blade surfaces) of the 15
1 and the thickness of the protective films 12, 12 are set to 0.3 to 10%. As a result, the tip of the blade 15 cuts the coated noble metal sheet 13 and at the same time, the gold foil 1 in contact with the blade surface is cut.
1 is bent, and the inner layer 12b of the protective film 12 is formed thereon.
Covers the end surface of the gold foil 11 (see FIG. 2).

In Table 1, the exposure of the gold foil observed with the naked eye and a 50 × optical microscope was defined as “appearance observation”, and after immersion in aqua regia at 50 ° C. for 12 hours, the concentration of gold in the aqua regia was measured using an ICP emission spectrometer. Is referred to as "aqua repellent", a portable test was performed, and the results of observing the appearance such as peeling of the end surface and the presence or absence of the gold foil with the naked eye and a 50-fold optical microscope were indicated as a "portable test".

に貴金属複合板の端部の被覆を行うことができる。As described above, the clearance d is 0.1%,
When 0.2% and 15% were used, the results were poor, whereas when the clearance d was within the range of 0.3 to 10%, all of the appearance observation, aqua regia dissolution, and the portable test were good. It can be seen that the setting within this range is preferable. As described above, the edge of the noble metal composite plate can be coated very easily only by performing the cutting while setting the clearance d of the cutting blade to a predetermined value.

When butyl carbitol or isobutyl acetate is applied with a brush, the result is good because the dissolved inner layer covers the end of the gold foil. in this way,
By simply applying the organic solvent to the end of the noble metal composite plate, the end can be coated very easily.

Since the part is covered, it can be seen that the result is good. Thus, the edge of the noble metal composite plate can be coated very easily only by cutting with the heated blade.

As shown in FIG. 1, the gold foil 11 penetrates into the vicinity of the end face, so that the appearance is improved and the decorative value is increased.
As shown in FIG. 2, since the end of the gold card 20 is covered with the inner layer 12b of the protective film 12, it is possible to prevent the gold foil from being rubbed during handling to change the amount of noble metal or to peel off the protective film. Is done.
