Description

[Detailed explanation of the invention] This invention is for stamping (printing) documents such as passbooks and certificates.
Forgery of seals or signatures affixed to columns or signature columns;
Concerning forms that are designed to prevent falsification.

At banks, etc., when a passbook is issued, the customer registers the seal by stamping the customer's seal in the delivery seal column on the back of the passbook at the counter, and when withdrawing money,
Identity verification is performed by comparing the stamp on the passbook and the stamp stamped on the deposit refund request slip submitted by the withdrawer. but,
If your passbook is stolen, there is a risk that someone else may tamper with the delivery seal column and affix a different seal to easily withdraw your deposits.

For this reason, conventional bank passbooks have a seal made of a transparent plastic film with a thickness of 20 to 50 μm in the delivery stamp column after the stamp is affixed to prevent staining and protection of the stamp impression, as well as to prevent falsification and counterfeiting as described above. is being pasted.
Furthermore, in order to prevent plastic films from being replaced, plastic films with a light transparent color or background pattern are used, or small cuts are made around these plastic films.

On the other hand, since passbooks are subjected to mechanical processing such as writing, etc., it is inevitable that the endpapers have a strong surface strength. Therefore, it is possible to cleanly peel off the above seal using a cutter knife, etc. Therefore, after peeling off the seal, it is possible to tamper with it by scraping off the seal imprint on the delivery stamp field and affixing another seal, and then apply the above seal again. It was not impossible to reattach it.

This invention was made in view of the above circumstances, and the purpose is to provide a form that can prevent forgery or falsification of seals, signatures, etc. affixed to the seal area or signature area of forms such as bankbooks and certificates. shall be. In other words, this invention is based on a form that has a seal area or a signature area, in which a pattern such as a background pattern or a fine pattern is printed on the base formed in the seal area or the signature area, and The object of the present invention is to provide a form characterized in that a transparent or nearly transparent peeling layer and a translucent porous layer having good ink absorption properties are laminated with the pattern interposed therebetween.

Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiments.

FIG. 1A shows an embodiment of the present invention.
is the base on which the seal area or signature area for passbooks and certificates is provided, and the upper part has a pattern such as a background pattern or fine pattern 3
is printed. A transparent or nearly transparent peeling layer 4 and a well-adherable translucent porous layer 5 are laminated in this order on the upper surface of the stamping field or signature field with a pattern 3 in between. This release layer 4 is made of varnish (for example, PB-80-
A material (coating agent or ink) with good release properties such as OP varnish (manufactured by Toyo Ink Manufacturing Co., Ltd.) or wax (paraffin wax, etc.) is applied onto the substrate 1 by gravure printing, silk screen printing, etc. It is formed to have a thickness of several tens of micrometers.

In addition, the translucent porous layer 5 is coated with ink (i.e., stamp ink such as vermilion ink,
It is made of a translucent material that has good ink absorption properties for sign ink, type ribbon ink, etc. Specifically, a pigment foil or ink containing oil-absorbing and water-absorbing extender pigments such as calcium carbonate, calcium sulfate, aluminum white, and calcium silicate is used, and is coated on the release layer 4 with a thickness of several μm to several tens of μm, for example. (For example, ink containing a pigment with high hiding power such as titanium white and a solvent in a weight ratio of about 6:4 or 7:3)
(It is recommended to form a layer with a thickness of 25 μm). Furthermore, on the upper surface and/or lower surface of the translucent porous layer 5, counterfeiting and
Letters or patterns may be attached to the image for the purpose of preventing tampering.

A seal or signature is affixed to the seal or signature field having such a structure, and ink is permeated into the translucent porous layer 5 (8 is an ink permeation part), and then the seal 6 is peeled off, as shown in FIG. 1B. Translucent porous layer 5
The whole is peeled off from the peeling layer 4 together with the seal 6. Therefore, no translucent porous layer 5 remains on the substrate 1, making it difficult to tamper with the seal or signature. Further, regarding the seal 6, it is difficult to cleanly remove the adhered semitransparent porous layer 5 impregnated with ink from the seal 6, making it extremely difficult to reuse it. In addition, in order to further ensure that the seal 6 is not reused, small cuts are made around the seal 6, similar to those made around the price sticker or part of the seal of a synthetic resin packaging bag. Good too.

In addition, in the present invention, since the translucent porous layer 5 is provided on the transparent or almost transparent peeling layer 4, each pattern observed in the stamp field or signature field before and after peeling off the sticker 6 is The contrast feels completely different. Such a change would surprise and deter would-be counterfeiters and falsifiers. Even if a seal or signature is forged or tampered with by forming what appears to be a translucent porous layer on the exposed release layer 4 using white obscuring ink, which is often used for letter correction these days. It is very difficult to adjust the opacity and color matching, and if you closely observe the condition of pattern 3 in the resealed seal or signature field, it will become clear that some kind of manipulation has been done in the position. Probably.

On the other hand, FIG. 2 shows a modification corresponding to the embodiment shown in FIG. 1, and the difference from the example shown in FIG. 1 is that the translucent porous layer 5 is formed wider than the release layer 4. The rest of the configuration is the same as that in FIG. 1, so a description thereof will be omitted. In this case, when the seal 6 is peeled off, the part of the translucent porous layer 5 adhering to the base 1 undergoes interlayer separation from the middle, and the part of the translucent porous layer 5 adhering to the peeling layer 4 As shown in Figure 1B, the whole is peeled off. For the same reason as in the above embodiment, it is not only difficult to falsify or forge, but also to make it difficult to falsify or forge.
The characters and background pattern on the base 1 are cut off, so even if someone tries to affix a different seal by doing some processing on the release layer, the characters and background pattern are cut off, making it difficult to tamper with or forge. Can be finished if possible.

As detailed above, according to this invention, since the seal, signature, etc. are performed through a porous layer that has good permeability to ink, it is effective to prevent falsification or forgery of the stamp field or signature field of the form. can be prevented.
