防を整えることが要請されている。(Prior art and its problems) In various fields of today's diversified society, there are documents that cannot be read and obtained by others or other than specific parties, such as confidential texts, codes, and Can-U card registration numbers. Very often there is a need to transmit confidential information, especially by copying it. In particular, in these days when money is easily transferred based on PIN numbers, there is a need for a security system that allows only a very small number of people to manage the PIN numbers in order to prevent crimes caused by the acquisition of PIN numbers. ing.
そのために、例えばＸ線等を用いた場合にのみ前記秘密

れるが、実際にこれを実施するには解決すべき困難点、
例えばＸ線による破曝を避けること等の問題が存在する
。For this purpose, a system is being developed that allows the secret text or password to be read only by using X-rays, etc., but there are some difficulties that need to be resolved in order to actually implement this system.
For example, there are problems such as avoiding radiation exposure due to X-rays.

（発明の内容）
本発明にいう炊Ｘ線、超軟Ｘ線とは紫外線とγ線の間に
波長域を持つＸ線のうち紫外線に近い波長域を持つもの
を云う。(Contents of the Invention) The hot X-rays and ultra-soft X-rays used in the present invention refer to X-rays that have a wavelength range close to ultraviolet rays among the X-rays that have a wavelength range between ultraviolet rays and gamma rays.
この２つのＸ線は被曝の危険が全く無く、容易かつ簡便
に扱え、しかも装置も簡単であるため、非常に優れたも
のである。These two X-rays are extremely excellent because they have no risk of exposure, are easy and convenient to use, and have simple equipment.
しかしながら、この種のＸ線を用いた場合、通常考えら

テン酸カリウム、タングステン酸銀−酸化マグネシウム
、タングステン酸等がまたはこれらの混合物が例示され
る。However, when this type of X-ray is used, it has been found that it is difficult to read barium compounds, iron fine powder, etc., which are usually considered, at the amount added to a normal carbon ink layer. Therefore, as a result of examining various metals and metal compounds among various compounds, the present inventors found that the density is 10 or more, especially 11.
It was found that compounds of ~20 metals have extremely high sensitivity to the above two types of X-rays, are not toxic, and can be easily made into inks. Examples of such metal compounds include carunium tungstate, magnesium tungstate, potassium tungstate, silver tungstate-magnesium oxide, tungstic acid, and mixtures thereof.
上記化合物のカーボンインキ中での含有量は４０〜８０

が悪くなり実用上問題がある。The content of the above compound in the carbon ink is 40 to 80
% is appropriate, and if the content is less than 40%, it will be soft
If the amount exceeds 80%, the ink fluidity of the carbon ink deteriorates, which poses a practical problem.

クス、パラフィンワックス等が例示される。The above compound is usually blended with a wax or wax substance having a melting point of 30-120 DEG C. and used as a wax-type carbon ink. Such waxes or waxy substances include carnauba wax, montan wax, auriculie wax, coconut wax, sugar cane wax, candelilla wax, Hoechst wax (o: op, s, etc.), Varico wax (WB polywax, etc.) ), polyethylene wax, oxidized microwax, paraffin wax, etc.

油が有用である油の配合量は通常カーボンインキ全量の
約５〜５０％にする。The wax-type carbon ink obtained by mixing with the above wax can be appropriately blended with oil to plasticize it and improve transferability. Mineral oil and non-drying vegetable oil are useful as additive oils. The amount is usually about 5 to 50% of the total amount of carbon ink.
また、上記化合物の外に通常の着色顔料、例えばミロリ

判読できないようにずろ必要がある。Furthermore, in addition to the above compounds, it is also possible to add ordinary colored pigments such as Milori Blue, N'Anin Blue, Lake Red, Pendinone Yellow, Cyanine Green, etc. to improve the hiding properties of the ink. It is necessary to print a camouflage pattern of the same color on the part and offset it so that the letters etc. cannot be read.

のか一般的である。The transfer sheet of the present invention can be prepared by melting the above-mentioned carbon ink at a temperature below its melting point, preferably at a temperature about LO°C higher than its melting point, and coating it on one side of a base sheet, such as paper, cellophane, plastic film, etc. It is common to use so-called cold cent printing, in which the material is printed in a vacuum and then immediately cooled to solidify and set.

よる筆記文字の判読を不可能にするのが好ましい。The carphone receiving sheet used in the present invention has advantages such as potentially improving the ability to hide carbon ink transferred by pressure applied to carphone transfer sorting. Preferably, the concealed portion of the carbon receiving sheet is embossed to make it impossible to read the written characters under flat pressure.

It is transferred in a potentially hidden state (unreadable to the naked eye), and this receipt sheet is read using a soft X-ray or ultra-soft X-ray imaging system (for example, the 50FT imaging system manufactured by Softex Co., Ltd.). I can do things.
