Field of the Invention The present invention relates to counterfeit-proof securities that are difficult to forge and whose authenticity can be easily determined even if they are counterfeited. (Prior Art) Recently, electrophotographic printing devices called laser beam printers that electrostatically transfer and heat-fix heat-fusible toner have become popular, and high-speed printing with non-impact printers has become possible. Needless to say, impact printers have the advantage of being noiseless. However, in laser beam printers that use infrared light irradiation with xenon lamps to simplify the fixing mechanism and avoid unnecessary heating of the paper, Because the fused toner does not adhere to the paper very firmly, it has the disadvantage that it is more susceptible to tampering than impact printers.For this reason, important documents such as securities are printed using non-impact printers such as laser beam printers. No printing was done.

In view of the above-mentioned circumstances, an object of the present invention is to transfer a heat-fusible toner by an electrostatic method and fix it by irradiating it with infrared light to print using a non-impact printer. To provide a security that prevents forgery, in which it is difficult to forge the printing, and even if the printing is forged, it is easy to determine whether it is genuine or fake. [Means for solving the problem] The securities of the present invention transfer heat-fusible toner onto paper using an electrostatic method, and fix the toner by irradiating it with infrared light. Securities produced by printing necessary information are characterized in that a heat-sensitive coloring agent is applied to at least the printing area of the paper surface. Typical securities of the present invention include gift certificates, gift certificates, and cash certificates such as deposit refund certificates. Of course, common matters on the face of securities may be provided in advance by general printing. General printing is performed by any printing method such as letterpress printing or offset printing. Paper that is commonly used for securities, such as high-quality paper, OCR paper, MICR paper, securities paper, non-impact printer paper, and colored overprint paper, may be used. As the heat-sensitive coloring agent, those commonly used for heat-sensitive recording paper and the like can be used. The heat-sensitive coloring agent can be applied to the paper by printing on the surface in required areas by gravure printing method or other printing means, or by applying a bart coating or coating the entire surface. The entire paper may be impregnated with the impregnating agent during or after the paper is formed. [Function] As shown in FIGS. 1A and B, the heat-fusible toner 3A is transferred by an electrostatic method to the paper 1 of the securities paper to which the heat-sensitive coloring agent 2A has been applied in the amount column. On the other hand, as shown in FIG. 2, when the number N 23J is printed by irradiating infrared light with the xenon lamp 4 and fixing it, the toner 3B that absorbs the infrared light and melts. Thermosensitive coloring agent 2 that developed color due to heat
It becomes B. Note that the heat-sensitive coloring agent below the ink other than white or black ink reflects infrared rays, so it does not receive heat and does not develop color. As shown in FIGS. 3A and 3B, when the number "1" is scratched off and a false number "9" is written in that area, the uncolored heat-sensitive coloring agent 2A around the character is also scraped off. When the entire amount column of the securities paper is heated, the uncolored heat-sensitive coloring agent 2A becomes colored heat-sensitive coloring agent 2C, as shown in Figure 4 A and B, and the correct number "1" is scratched off to create a false number. The portion marked with "9" remains uncolored. Therefore, it is immediately obvious that the correct numbers have been deleted and false numbers have been written. Another method of counterfeiting is to apply a polyester film to a cash voucher that has numbers printed in a similar shape, heat it with an iron, copy the numbers, and transfer it onto a blank sheet. Even if you try to do this, when the amount column is heated during transcription, the surroundings of the letters will also develop color, making it possible to detect counterfeiting. Once someone has experienced this, they will never attempt counterfeiting using this technique again or use a counterfeit ticket. R Plate 543 The counterfeit-proof securities of the present invention are difficult to counterfeit due to the above-mentioned effects, and even if they are counterfeited, it is easy to determine whether they are genuine or false, and as a result, counterfeiting is prevented. be able to. Although the present invention can be applied to various securities, it is particularly meaningful when applied to gold certificates.
