Description

[Detailed Description of the Invention] The present invention relates to a copy slip set, and more particularly to a copy slip set that prevents leakage and forgery of information such as characters, symbols, and figures copied onto the slip.

Traditionally, information such as characters and symbols copied onto a slip was copied onto the slip using a method of ablation or using special chemicals as a method of maintaining confidentiality during the process of transmission from the issuer of the slip to the legitimate right holder. The information recording section is made invisible, and when the slip is delivered to the legitimate right holder, the legitimate right holder performs some kind of processing (heating or other processing) on the slip to make the information recording section visible. There are known ways to make it visible.

However, in these methods, once the information recording section is revealed, it can be read by anyone, so there is a risk that the information will be leaked to a third party other than the legitimate rights holder when storing it.

In addition, since it is not possible to hide the information recording section again after it has been revealed, the same slip is used when transmitting information from one legitimate right holder to another legitimate right holder. There is a disadvantage that the information recording section is hidden and a document must be created again without being able to do so.

In addition, on the back side of the first slip, a pressure-sensitive copying ink layer containing a fluorescent substance that emits light with ultraviolet light with a wavelength of 200 nm or more and 300 nm or less and a fluorescent substance that emits with ultraviolet light with a wavelength of more than 3001 m and less than 4501 m is applied. A second slip is placed under the first slip, and a surface area of the second slip facing the pressure-sensitive copy ink layer is coated with a solid or background pattern of the same color as the pressure-sensitive copy ink layer. Using a set of slips with a concealing printing layer, fill in the necessary information on the first slip and copy it onto the second slip, and the slip with this information copied will be authenticated by the slip issuer. A method has been proposed in which the legitimate right holder sequentially irradiates the slip with two types of ultraviolet light with different wavelengths and reads the information recorded on the slip using the light emitted from a fluorescent substance, but this is not necessary. When writing information on the first slip and copying it onto the second slip, the pressure of the pen will cause dents in the second slip, so if you scratch the surface of the slip with a pencil or hold it up to light, The problem is that the information can be read.

Therefore, as a result of research to eliminate Narukami's shortcomings, the inventor of the present invention found that
We have discovered that if an irregular embossed pattern is applied to the concealing printing layer provided on the surface of the second slip, leakage of confidential information can be completely prevented.Based on this knowledge, we devised the present invention. This is the completed version.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a set of copy slips according to the present invention.

It consists of a slip 1 and a slip 2 that overlaps with the slip 1, and on the back side of the slip 1 there is a fluorescent substance that emits ultraviolet light with a wavelength of 200 nm or more and 30 Q nm or less, and a fluorescent substance that emits ultraviolet light with a wavelength of 200 nm or more and 30 Q nm or less and a wavelength of 450 nm that exceeds 3 Q Q nm.
A pressure-sensitive copying ink layer 3 containing a fluorescent substance that emits light with ultraviolet light having the following wavelengths is provided, and the pressure-sensitive copying ink layer 3 is provided on the surface area of the slip 2 facing the pressure-sensitive copying ink layer 3. A concealing print layer 4 made of a solid or tint pattern of the same color as is provided, and an irregular concealing embossed pattern 7 is embossed thereon.

The copy slip set of the present invention includes at least one slip set 5 consisting of the above-mentioned slips 1 and 2.

In addition, in the copy slip set of the present invention, in order to hide only the PIN number and make the information such as name and address readable, concealment printing is applied only to the area corresponding to the PIN entry field. It goes without saying that it is good to have layers and an enhanced pattern.

When necessary information that must be transmitted confidentially is recorded on slip 1 of the copy slip set of the present invention, the same color as that of the concealing print layer 4 is also printed on the concealing print layer 4 of the slip 2. Ink containing a fluorescent substance is deposited to copy information.

Figure 2 shows the slip 2 on which the information has been copied, and the information 6 cannot be read by simply looking at it with the naked eye because the color of the letters recording the information 6 and the color of the concealing printing layer 4 are the same. .

Further, since the irregular embossed pattern is applied, even if the slip 2 is dented due to pen pressure during copying, the information 6 cannot be read.

However, by irradiating the slip with ultraviolet light with a wavelength of 200 nm or more and 300 nm or less, a fluorescent substance that reacts to the ultraviolet light emits light, and information 6 can be read as shown in Figure 3. By irradiating ultraviolet light with a wavelength of 450 nm or less, the fluorescent substance that reacts to the ultraviolet light emits light, and the information 6 can be read.

In addition, in the present invention, the wavelength of ultraviolet light is 200 nm or more and 300 nm or less, but this wavelength of ultraviolet light cannot be obtained unless a special filter is used in the germicidal lamp to cut off the visible light part. First, since the special filter is generally difficult to obtain, the number of fluorescent substances used in the slip is not known, and it is effective in preventing counterfeiting of slips.

In addition, a fluorescent material that emits ultraviolet light with a wavelength of 450 nm or less beyond 3001 m emits light when it is irradiated with light from a normal germicidal lamp.

The above-mentioned germicidal lamp contains light with a wavelength of 200 nm to 450 nm, of which light with a wavelength of 200 nm to 300 nm does not interfere with visual observation of the luminescent state of the fluorescent substance, so there is no need to cut it with a filter.

As detailed above, according to the copy slip set of the present invention, the information copied on the copy slip can be transmitted from the slip issuer to the legitimate rightful holder in a state of confidentiality. It can be effectively used for transmitting information that should not be known to others, such as a password code.

Furthermore, since it uses two types of fluorescent substances that react to ultraviolet light of different wavelengths, it is effective in preventing counterfeiting of slips.

In other words, even if a genuine slip is irradiated with ultraviolet light having one of the two wavelengths and a fluorescent material that reacts to the ultraviolet light is found to forge a slip, it is possible to forge a slip by irradiating it with ultraviolet light having the other wavelength. It is possible to determine whether the slip is genuine or not.
