Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal registration certificate which has been counterfeited or falsified.

[0002]

2. Description of the Related Art In recent years, in general, each city or ward office has generally adopted an issuing system using a seal registration certificate when issuing a seal certificate based on an application. As a result, it becomes possible to easily issue it even at branch offices such as branch offices, and it is a convenient system that is well received by both the public office and users.

This seal registration certificate is generally printed on a base material such as paper or a plastic sheet with a pattern layer such as a tint block, a fine pattern, a symbol mark of a city or a ward office, and an ID number such as a number or a bar code. Alternatively, it is stamped to have a card shape having a size substantially equal to that of a credit card, a cash card, or the like. The seal stamp certificate is issued by this seal stamp registration certificate, but the present condition is that the seal stamp registration certificate and the confirmation items of the seal stamp certificate to be issued are performed by collating the ID number of a numeral or barcode and the ledger number.

[0004]

However, in the above-mentioned seal registration certificate, only the ID number proves uniquely,
For example, the defense measures against forgery and falsification of the ID number on the seal registration certificate were not perfect. Therefore, it is not possible to determine whether the seal stamp registration certificate is a true one for the registered seal imprint, or has been forged or tampered with, and this determination is made only by checking the ID number.

Therefore, the present invention provides a new seal stamp registration certificate in which the seal stamp registration certificate is divided into visible information by visual inspection and invisible information and the seal stamp registration certificate cannot be forged or falsified. Is.

[0006]

In order to solve the problems, the seal registration certificate of the present invention is a seal (registered copy) of a Y, M, C process ink as visible information on a base material (11) made of paper or a plastic sheet. In the seal registration certificate formed in the shape of a card by providing the pattern layer (13) and the ID number (12) consisting of numbers, barcodes, etc., the visible layer has the infrared region in the pattern layer (13) region. The printing layer (15) made of a transparent invisible ink that is identifiable by (1) is provided.

In addition, the printing layer (1
5) is characterized by being an imprint.

Further, the invention is characterized in that the ID number (12) consisting of the numeral, bar code and the like is provided in a print form with invisible ink.

The invisible ink is characterized by being composed of a transparent ink containing an infrared absorbing agent as a main component.

The present invention will be described in detail. The seal registration certificate of the present invention is a base material (11) made of paper or a plastic sheet.
As the visible information, Y, M, and C process inks (process inks that do not absorb in the infrared region) are used for tint block, fine pattern,
The pattern layer (13) of the mark such as the city emblem or the ward emblem, and the ID number (12) such as a number or a bar code are provided on the pattern layer area or other areas by printing or engraving, and invisible information As the above, a printing layer (15) made of a transparent invisible ink that is identifiable in the infrared region is provided in the pattern layer region as the visible information. Base material (11)
Is, for example, paper or a plastic sheet and has a thickness of 0.1
~ 0.8 mm, preferably 0.5-0.8 mm
Is good. In addition, a note or the like can be printed on the back side. The above-mentioned base material, visible information and the like are not limited and can be appropriately selected.

One of the methods for forming the seal imprint of the seal registration certificate is to read the seal imprint of the actual seal once and directly output it as an image to the intermediate product of the seal registration certificate with invisible ink, and to replace the red stamp for stamping. In addition, it is a method to have the person directly imprint with a red ink made of invisible ink (there is no color of red, hereinafter referred to as invisible red ink). That is, a printing layer (15) made of a transparent invisible ink containing an infrared absorbent as a main component is provided in the vicinity of the center of the pattern layer (13) region made of the Y, M, C process inks. Further, instead of this printing layer, when a seal registration certificate is issued, a real stamp is imprinted on the pattern layer (13) area of the visible information using a transparent invisible red ink. It is preferable that the protective layer (14) is provided on the printed layer (15) of the invisible ink or the invisible red ink after imprinting the actual mark. As this protective layer, for example, a transparent vinyl chloride sheet having a thickness of about 0.1 to 0.15 mm is attached or a protective varnish is applied to obtain a seal registration certificate. It is also possible to print either or both of the numbers and the ID numbers such as barcodes in advance with the transparent invisible ink.

The invisible ink identifiable in the infrared region has an infrared absorbing agent as a main component, and as the infrared absorbing agent, a metal complex type, a phthalocyanine type, an aminium type, a phosphate glass type, a nitrate glass type is used. Etc. can be used. Further, the addition amount can be appropriately selected from 1 to 50 parts by weight / resin. An example of the composition of the invisible ink containing the infrared absorbent as a main component is shown below.・ Metal complex infrared absorber SIR-159 1 part by weight (manufactured by Mitsui Toatsu Dyestuff Co., Ltd.) ・ Resin VAGH 10 〃 (manufactured by Union Carbite Co.) ・ Solvent MEK 20 〃 Toluene 20 〃 ・ Hardener D24A100 2 〃 (Asahi Kasei) (Made by corporation)

In the pattern layer (13) area which is the visible information of the seal registration certificate, a printing layer (15) is provided with invisible ink, or a real stamp is imprinted with invisible red ink,
The printed layer or the imprint of the official seal cannot be visually confirmed, but only the pattern layer (13) of the lower Y, M, and C process inks or only the ID number can be visually confirmed. FIG. 4 shows an example of an infrared absorption spectrum in which the density of the pattern layer and the print layer of the invisible ink having the above composition are changed. In order to confirm this invisible information, it cannot be determined without using an infrared scope. That is, infrared rays are absorbed by the infrared absorber, and only the invisible ink portion can be clearly confirmed. An example of the spectrum of this infrared absorber is shown in FIG. This allows
A forged or falsified seal registration certificate can be easily found with an infrared scope. In addition, the seal stamp registration certificate in which the real seal is stamped with the invisible red ink can be collated with the issued seal stamp certificate and the seal imprint of the seal stamp registration certificate.

[0014]

The seal stamp registration certificate of the present invention is a seal stamp registration certificate in which a real seal is imprinted with a printing layer (15) made of a transparent invisible ink containing an infrared absorbent as a main component in the pattern layer area of visible information, or an invisible red ink. Therefore, even if the uppermost protective layer (14) is peeled off with a solvent or the like, or the print layer (15) made of invisible ink or the seal imprint of invisible red ink is erased, the visible information pattern layer (13) or ID Number (1
Since 2) is dissolved, it is impossible to forge or falsify. Further, since the invisible information is confirmed by using the infrared scope, it is possible to easily determine (counterfeiting or falsification) a change in the print layer (15) or the imprint by the invisible ink.
