Description

[Detailed description of the invention] The present invention is a copy slip, in particular, the copy information such as copy characters and numbers formed on a desired part of the copy paper by applying pressure on one side of the copy paper with a writing instrument, etc. , relates to a copy slip that cannot be identified under light sources such as incandescent light bulbs, fluorescent lights, and the sun (hereinafter referred to as normal light sources).

Checks, bills, insurance policies, etc. have sophisticated counterfeiting and tampering prevention measures, making them extremely difficult to forge or tamper with. However, carbon paper, back carbon slips, etc., which have a pressure-sensitive copying layer formed on the back of the paper itself for office slips, etc., are used.
Copy information that is copied and recorded on the surface of paper to be copied, such as a receipt or a form, has the disadvantage that it is easily forged or tampered with.

On the other hand, when applying for a cash card for personal deposit withdrawal at a bank, etc., the application is made using a prescribed application form provided at the bank counter. This application form is usually in the form of a copy slip. They are used in various procedures for card issuance. Once the procedure is completed and the card is issued, a predetermined number of copies will be kept in a predetermined department of the bank. This is to serve as a ledger for issuing cards, and predetermined information will be entered and left behind.

One of the pieces of information is your personal PIN number, and it should not be allowed to be seen by third parties.
It is necessary to store it strictly. If the PIN number is leaked to a third party, there is a risk that a separate card containing the PIN number will be forged.

However, when a customer makes an introduction or inquires about the PIN number after the card is issued, the ledger may be needed to confirm the person's handwriting, so it is necessary to save the ledger. Therefore, it is desirable to have a structure that retains the person's handwriting and is normally not legible to the naked eye.

The present invention was developed in view of the above-mentioned circumstances, and it is possible to transfer the pressurized portion onto the surface of another adjacent base material by applying pressure with a typeface or other writing instrument. The purpose of this document is to provide a copy slip in which transferred copy information such as letters and numbers cannot be distinguished under normal light sources, and which also has the effect of preventing counterfeiting and tampering.
The gist of this is that copying paper is provided with a pressure-sensitive copying layer made of pressure-sensitive copying ink on one side of the base material, and the copying area on one side of the other base material is decorated with decorative ink. At least one pair of paper sheets provided with a pattern are provided, the pressure-sensitive copying layer and the copying area facing each other and adjacent to each other, the pressure-sensitive copying ink and The purpose of this decorative ink is that it has been adjusted to exhibit metamelability under normal light sources such as incandescent lamps, fluorescent lights, and the sun.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows an embodiment of a copy slip 10 according to the present invention. In the figure, reference numeral 11 indicates copy paper, and reference numeral 12 indicates copy paper, and the pressure-sensitive copy layer 2 and copy target portion 5 are bonded by adhesive at an adhesive portion 13 so that they can face each other and be adjacent to each other. ing. Also,
Reference numerals 1 and 3 indicate a base material made of paper, plastic, etc., and 4 indicates a decorative pattern formed on a copying area 5 of the base material 3, respectively.

The pressure-sensitive copying layer 2 formed on one side of the base material 1 is
The structure is as shown in FIG. 2, and a colorant (carbon black, channel blue, channel black, etc.), an extender pigment (alumina white, calcium carbonate, diatomaceous earth, etc.), and a binder are coated on one side of the base material 1. and a plasticizer (dioctyl phthalate, mineral oil, etc.) using a pressure-sensitive copying ink, which is applied by printing or coating. In this embodiment, the pressure-sensitive copying layer 2 is formed directly on the base material 1, but in order to improve the transfer of the pressure-sensitive copying layer 2 to the copying paper 12, a release layer is formed between the pressure-sensitive copying layer 2 and the pressure-sensitive copying layer 2. It may also be formed between it and the base material 1. Naturally, on other parts of the base material 1, notes 8 necessary for the slip are formed using ordinary ink.

Decorative pattern 4 applied to copying area 5 of base material 3
Irregular patterns or background patterns as shown in the drawing,
A fine pattern is preferable, and is provided by printing with decorative ink onto the copying area 5 set on one side of the base material 3 (see FIG. 3). This copying area 5 is a copy paper 11
When the paper 12 to be copied and the paper 12 to be copied are overlapped with the adhesive part 13 as a fold (in FIG. 1, the straight adhesive part 13
In this embodiment, an embossed pattern is formed over the entire copying area 5, which is the part that contacts the pressure-sensitive copying layer 2. This is provided to prevent writing marks from being left on the base material 3, and it is more effective if it is embossed with an irregular pattern.

Furthermore, as described above, the decorative ink constituting the decorative pattern 4 may be a printing ink used in normal printing. It is necessary to adjust the material so that it exhibits metamel properties under normal light sources such as lights and the sun. By doing this, what appears to be the same hue under a normal light source will be recognized as a different hue when viewed under a light source with a specific spectral energy distribution or through a filter with specific light absorption characteristics. become.

For example, if the hue of the pressure-sensitive copying layer 2 is set to gray made by mixing green and purple pigments, and the hue of the decorative pattern 4 is set to a mixture of mainly white and black pigments, incandescent light bulbs, fluorescent lights, etc. When the copy slip 10 according to the present invention is set to a gray color that is the same color as the gray under the light source, the copy information copied on the cover pattern 4 of the copy slip 10 will be Naturally, they appear to be the same hue and cannot be distinguished, but when observed under a light source that emits visible light with a different spectral energy distribution, the two appear to be different hues, for example, one appears to be a very reddish gray. The copy information will be clearly recognized. Of course, this phenomenon is also observed when the irradiation light source is used as it is and the image is simply observed through the filter as described above. This confirmation becomes possible as the hue changes, and must be done in a bright place.

Since the present invention has the above configuration, copy paper 1
1 and copying paper 12 are overlapped with the adhesive part 13 as a fold, and when pressure is applied with a writing instrument from the base material 1 side to the copying paper 12 side, the paper 12 is adjacent to the pressure-sensitive copying layer 2. The pressure-sensitive copying ink of the pressure-sensitive copying layer 2 corresponding to the pressurized portion of the copying area 5 is transferred,
Copy information will be transcribed and recorded. This state is shown in FIGS. 4 and 5. Since FIG. 4 shows the state of the copying area 5 under a normal light source, the copy information made of pressure-sensitive copying ink is not visible to the naked eye due to the ornamental pattern and uneven hue.

However, when the copy paper 12 on which copy information is recorded as described above is observed under a light source with a specific spectral energy distribution or through a filter having specific spectral absorption characteristics, as shown in FIG. The hue of the copy information 15 and the hue of the decoration pattern 4 are perceived as different hues,
The copy information 15 can now be determined.

Therefore, the copy information on the copy paper obtained using this copy slip cannot be confirmed unless a special light source or special filter is used, which prevents leakage of copy information and further prevents forgery and tampering. It also becomes effective.
