Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a postcard having a confidential document surface which cannot be watermark-readable even when it is held up to light.

[0002]

2. Description of the Related Art Postcards and letters have been used in postal services for some time.

[0003]

However, postcards are easy to write, but the document surface is bare and a sentence that requires confidentiality cannot be written. Therefore, when it is necessary to conceal a letter, write it in a letter and put it in a single envelope with shielding paper or in a double envelope having a shielding function, but it is cumbersome and wasteful to attach the shielding paper. In addition, a letter cannot be sent out even if the letter paper or envelope is cut, and when it is short, it feels exaggerated and awkward.

An object of the present invention is to provide a postcard with a confidential document surface which solves these drawbacks, to keep the secret and to use the mail easily.

[0005]

In order to achieve this object, the postcard of the present invention is a paper having a shielding layer 3 between a front white surface 1 and a back white surface 2, as shown in FIG. Like 2,
It has a surface 4 such as an address or the like on one side, a normal document surface 5 which is exposed when laminated, a folding line 6 and perforations or shallow knife eyes 7, and a confidential document surface 8 and a margin 9 on the other surface. It is a thing.

There are various methods for producing a paper having a shielding layer suitable for the present invention. For example, in a paper making process, first, a non-colored fiber is plowed to an appropriate thickness, and then a dark black color that does not dissolve in the paper making liquid is added. A method of adding the required thickness with colored fibers and finally raising the appropriate thickness with uncolored fibers.

[0007] One surface of each of the two white papers is sufficiently filled with black ink or the like, and the two black surfaces of the two papers are bonded together. Or, attach other white paper to one black surface.

It can also be manufactured by sticking white paper on both sides of black-colored paper or a plastic film or on both sides of a soft metal foil such as aluminum.

The postcard of the present invention is white on both sides like a normal postcard, and in use, after it has been turned into a face 4 for address or the like, a confidential document face 8 and a normal document face 5, etc., the confidential document face 8 is used.
On the inside and fold along the folding line 6 to attach the glue allowance 9. When reading, tear perforations or shallow knife eyes 7 to open. It should be noted that although a sentence that may be read by another person is usually written on the document surface 5, an advertisement or the like may be printed.

[0010]

Since the postcard of the present invention is used by sticking the confidential document surface 8 inside, the confidential document surface 8 is not directly touched by others, and the confidential document surface 8 is protected by the shielding layer. It is read, and it is not read even if it is held in the light.
