られている。When transmitting information records such as symbols 9 figures, etc., as a method for transmitting the information records copied and copied onto the copy paper only to the legitimate rights holders without leaking them to third parties other than the legitimate rights holders. , a special chemical treatment is applied to the information recording portion copied on the surface of the copy paper to make the information recording portion invisible, and when the copy paper is delivered to the rightful right holder,
There is a known method in which a legitimate right holder heats or otherwise processes the copy paper to make the information recording portion visible and readable.

である。However, in the conventional method, once the information recording section on the copy paper surface is made readable, it can be read by anyone after that, so the copy paper that has been processed to make it readable is When storing, there is not only a risk that the information record will be leaked to a third party other than the legitimate right holder, but also the information recording section of the copy paper that has been processed to make it readable.
Since the knee cannot be made invisible again, the same copying paper cannot be used when transmitting information from one legitimate right holder to another. First, there is the complexity of having to use copying paper in which a separate information recording section is made invisible. When copying ink is used to form a pressure-sensitive copying ink layer on pressure-sensitive copying base paper, all of the above-mentioned drawbacks of conventional pressure-sensitive copying paper are eliminated, and third parties other than legitimate rights holders It is thus possible to provide a pressure-sensitive copying paper capable of producing an unreadable information record on the surface of the copying paper.
以下、本発明の感圧複写用インキの構成について詳述す

る。The pressure-sensitive copying ink of the present invention has a wavelength of 200 to 300 nm.
A mixed composition consisting of a colorless fluorescent pigment that emits light under ultraviolet light, an oil, and a wax, or a commonly colored pigment or an ethylene-vinyl acetate copolymer, or both of these are further added to and mixed with the mixed composition. In the total mixture composition forming the pressure-sensitive copying ink, colorless fireflies that emit light with ultraviolet light with a wavelength of 200-300 nm, photopigment content is 20-50% by weight, and oil content is 15-50% by weight. 40% by weight

ることが出来なくなるという欠点を生ずる。It is necessary that the colorless fluorescent pigment in the entire mixed composition constituting the pressure-sensitive copying ink of the present invention is one that develops color with ultraviolet light having a wavelength of 200 to 300 nm. This is because the original use of the pressure-sensitive copying ink of the present invention is to form a pressure-sensitive copying ink layer on pressure-sensitive copying paper for the purpose of preventing secret leakage to third parties. Copying ink layer
In order to create a pressure-sensitive copying ink layer that cannot be easily noticed by the operator, we selected a colorless fluorescent pigment that emits ultraviolet light with a wavelength of 200 to 300 nm, which has few mites and is difficult to obtain in the industry. , for example, Z n
2 S 104/Mn eCaW04. Or C,
Fluorescent pigments such as WO4/Pb can be used. In the pressure-sensitive copying ink of the present invention, when the colorless fluorescent pigment is less than 20% in the total mixed composition,
Copy paper using this method irradiates ultraviolet rays onto the surface of the copy paper after pressure-sensitive writing by the legitimate right holder, and when reading the information recording section, the recording section does not emit enough light, making it difficult to read. This results in the disadvantage of becoming. On the other hand, this fluorescent pigment
0. If the amount of fi exceeds %, the fluidity of the resulting ink itself will be impaired, making it difficult to form a pressure-sensitive copying ink layer on the surface of the copying base paper, and causing unevenness in the formed pressure-sensitive copying ink layer. However, this method has the disadvantage that it is not possible to form a uniform information recording area on the surface of the copy paper.

報記録部を形成し得なくなるためである。Liquid paraffin or vaseline is used as the oil component in the pressure-sensitive copying ink of the present invention, and this oil must be added and mixed within the range of 15 to 40% by weight in the total mixed composition. is necessary. This is because if the total mixed composition constituting the pressure-sensitive copying ink of the present invention contains less than 15% by weight of oil, the copying performance of the pressure-sensitive copying ink layer formed using this ink is poor, and the ink is This is because the original function of 40% by weight is insufficient.
This is because, if the amount exceeds 1, the degree of contamination of the pressure-sensitive copying ink layer formed on the surface of the copy paper becomes severe, and it becomes impossible to form a clear information recording portion on the surface of the copy paper.

得ることが困難となるためである。This is because if the wax component exceeds 50% by weight in the total mixed composition, the original pressure-sensitive copying function of the pressure-sensitive copying ink layer formed using this ink will be insufficient. In addition, if the wax component is less than 20% by weight, the pressure-sensitive copy ink layer formed on the copy paper surface will be highly contaminated, making it difficult to obtain clear information recording areas on the copy paper surface. It is.

、透過率が高いという特質を有するものである。As mentioned above, in the mixed composition constituting the pressure-sensitive copying ink of the Po invention, the oil is liquid paraffin or vaseline, and
The wax used is polyolefin wax such as paraffin, refined carnauba, or polyethylene wax, and all of these substances have wavelengths of 200 to 300.
It does not interfere with the luminescence of the fluorescent pigment in the composition upon irradiation with nanometer ultraviolet light, and has the characteristics of low absorption of the ultraviolet light and high transmittance.

In addition, since the draft polymer has a high transmittance of ultraviolet light, it improves the color development of the fluorescent pigment in the pressure-sensitive copying ink. It has the characteristic of not interfering with

A pressure-sensitive copying ink layer 5 made of the pressure-sensitive copying ink of the present invention is provided on a predetermined portion of the back side 4 of the copying base paper 1. surface 6
In the area facing the pressure-sensitive copying ink layer 5,
It has a structure in which a concealing printing layer 7 made of a solid or background pattern of the same color as the pressure-sensitive copying ink layer 5 is provided. A coloring pigment is usually added to the pressure-sensitive copying ink forming the pressure-sensitive copying ink layer 5.
含有されていないときには、前記複写用紙２の表面６の
隠蔽用印刷層７は必ずしも必要とされるものではない。When it is not contained, the concealing printing layer 7 on the surface 6 of the copy paper 2 is not necessarily required.

情報が複写される。When predetermined information is recorded on the copy paper 1 by pen pressure using a set of copy paper 3 having the above-exemplified structure, the surface 6 of the copy paper 2 is exposed to ultraviolet light with a wavelength of 200 to 300 nm. The information is copied with a pressure-sensitive copying ink containing a luminescent, color-banding pigment.

Therefore, although it is impossible to read with the naked eye, a legitimate rightful holder who obtained the copy paper 2 with the recorded copies may expose the copy paper 2 to a mercury lamp, for example, with light of 200 to 3 Q Q nm. The characters, symbols, pictures, etc. recorded on the copy paper 2 become legible only when the copy paper 2 is placed under a means such as attaching a special filter that transmits the paper.
