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 to prevent staining and protection of the seal imprint, as well as to prevent falsification and counterfeiting as described above. is being pasted.
Furthermore, in order to prevent this plastic film from being replaced, light transparent colored plastic films with tint marks etc. 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-mentioned seal using a cutter knife, etc. Therefore, after peeling off the seal, it is possible to tamper with the delivery stamp area by scraping off the seal impression and pressing another seal, and then apply the above-mentioned 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. .

That is, the present invention provides a form that has a stamp field or a signature field, on which a plurality of patterns are formed by a release layer, and a porous layer with good adhesive absorption properties is formed on the stamp field or signature field. The document is characterized in that it is formed to cover a release layer.

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 stamp or signature field for bankbooks and certificates is provided, and the top part has patterns such as background patterns and fine patterns3.
is printed. A plurality of patterns 10 are formed on the top surface of the stamp field or signature field by a peeling layer 4 through a pattern 3.
and a porous layer 5 with good adhesion are laminated in this order. This release layer 4 is made of varnish (for example, PB-80-
Using a material (coating agent or ink) with good release properties such as OP varnish (manufactured by Toyo Ink Seizo Co., Ltd.) or wax (paraffin wax, etc.), the substrate 1 is coated by gravure printing, silk screen printing, etc., for example, by several μm or several micrometers. It is formed to have a thickness of +μm. (See Fig. 3) The porous layer 5 is coated with ink (i.e., seal ink such as vermilion ink, signature ink, type ink, etc.) by means of printing or foil stamping so as to cover the release layer 4 and its surrounding area. It is made of a material that has good ink-absorbing properties against ribbon inks, etc. Specifically, a pigment foil or ink containing oil-absorbing and water-absorbing extender pigments such as calcium carbonate, calcium sulfate, aluminum white, calcium silicate, etc. is used, and a layer of, for example, several μm to several + μm thick is used on the release layer 4 and the substrate 1. (for example,
It is preferable to form an ink containing a pigment containing titanium white with high hiding power and a solvent in a weight ratio of about 6:4 or 7:3 in a thickness of about 10 to 25 μm). Furthermore,
The upper and/or lower surfaces of the porous layer 5 may be provided with letters or patterns for the purpose of preventing counterfeiting and tampering.

When a stamp or signature is affixed to the stamp field or signature field having such a structure, ink is permeated into the porous layer 5 (8 is an ink permeation part), and the adhesive sticker 6 is peeled off, as shown in FIG. 1B. The porous layer (5-1) provided through the release layer 4 is peeled off together with the adhesive seal 6 from the portion where it is in contact with the release layer 4, and the porous layer (5-1) which is not provided through the release layer 4 is peeled off together with the adhesive sticker 6. −
2) is separated into the base 1 side and the adhesive sticker 6 side.

Therefore, the stamp or signature on the porous layer 5 is separated into the adhesive sticker 6 side and the base 1 side, and it no longer retains its original form, and furthermore, it cannot be forged or tampered with (reformation of the porous layer 5, stamping, etc.). reshaping the signature, etc.) becomes extremely difficult. In addition, in order to further ensure that the adhesive seal 6 is not reused, small cuts, such as those made around the price sticker or at the △ section of the seal part of a synthetic resin packaging bag, are made in the periphery of the adhesive seal 6. It may be provided.

On the other hand, it is preferable that the porous layer 5 is colored white because the stamp or signature can be clearly observed, but it is not necessarily white and may be colored other colors. If the porous layer 5 is colored, color matching during its re-formation will become more difficult.

Further, this porous layer 5 may contain a substance that is excited to emit light when irradiated with actinic rays, such as an ultraviolet-excited luminescent substance or an infrared-excited luminescent substance. In this way, the seal field or signature field can be verified by causing the luminescent substance to emit light by irradiation with ultraviolet rays, infrared rays, or the like.

On the other hand, FIG. 2 shows a modification corresponding to the embodiment shown in FIG. 1, and the difference from the example in FIG. 1 is that the porous layer 5 is formed wider than that in FIG. The rest of the configuration is the same as that in FIG. 1, so the explanation thereof will be omitted. In this case, when the adhesive sticker 6 is peeled off, the porous layer (5-2) in the part that is adhered to the base 1 undergoes interlayer separation from the middle (the adhesion between the adhesive sticker 6 and the porous layer 5 is not so strong). (in this case, the porous layer (5-2) remains on the base 1 side), and the porous layer (5-1) in the part that adheres to the release layer 4 is attached together with the adhesive seal 6 as shown in FIG. 1B. Peel off. In addition, if characters or tints are attached to the porous layer 5 in advance, the characters or tints on the release layer 4 are attached to the adhesive sticker 6 on the periphery of the release layer 4.
Since it is interrupted when it is peeled off, even if someone tries to stamp a different seal by applying some kind of treatment to the peeling layer 4, the characters and ground pattern of the porous layer 5 that remain on the base 1 are cut off, making it impossible to tamper with or forge. It can be ended in

As detailed above, according to this invention, a porous layer with good ink permeability is formed so as to cover a plurality of patterned release layers. When the adhesive sticker that has been covered and adhered is removed, the porous layer separates into the base material side and the adhesive sticker side, making it difficult to re-form the porous layer, and eventually causing damage to the stamp or signature area of the form. Tampering and forgery can be effectively prevented.
