Field of the Invention The present invention relates to a fluorescent penetrating ink which can be used in the manufacture of printed matter such as securities to prevent tampering of printed characters and numerical information and the like and forgery of printed matter. And printed matter produced using the same.

Description of the Related Art Heretofore, there has been a printed matter in which characters and numerical information, which are to be protected from tampering or the like formed on paper, are printed using a permeable ink in which a coloring agent and a fluorescent pigment or dye are dispersed in a vehicle. .

場合、その部分の周囲に発光が生じないため、不正を発
見することができる。When the printed matter is irradiated with ultraviolet rays, a light emission slightly larger than that of the characters, numerals and the like is generated around the characters and numerals. This is because the fluorescent pigment or dye contained in the permeable ink is more likely to cause bleeding (penetration and bleeding) than the coloring agent serving as character and numerical information. It should be noted that if such a printed matter has been tampered with, such as falsification of characters, no light emission occurs around that portion, so that tampering can be detected.

字、数字情報等が不鮮明となり易いという欠点もある。A conventional permeable ink is an oxidative polymerization type ink which uses a drying oil (linseed oil and its modified oil) or an alkyd resin as a vehicle and oxidizes and polymerizes with air in the air to dry (cur). It is. Therefore, it takes time to dry the ink. Further, the ink contains a solvent. Further, there is a disadvantage that the colorant in the ink also bleeds, and characters and numerical information are likely to be unclear.

る。[0005] The inventors of the present invention have made a trial production of an ink prepared by mixing a fluorescent dye into an ultraviolet curable ink which is cured by reaction polymerization with ultraviolet light and evaluated. However, no light emission could be confirmed around the characters, numeric information, etc. of the printed matter using this. This is probably because the fluorescent dye hardly bleeds because the vehicle is instantaneously and firmly cured by the irradiation of ultraviolet rays during drying.

しない状態では、ブリードの存在を確認できなかった。Next, after the letter "T" was printed on high quality paper by offset printing using the above permeable fluorescent ink, the permeable fluorescent ink was cured by irradiating ultraviolet rays to obtain a printed product. When the printed matter was irradiated with ultraviolet light, blue fluorescent light emission due to bleeding of a fluorescent dye was observed around the letter "T". It should be noted that the presence of bleed could not be confirmed without irradiating the printed matter with ultraviolet rays.

による蛍光発光は殆ど見られなかった。Comparative Example An ink containing no bleed accelerating liquid was prepared from the above permeable fluorescent ink composition, and a printed material similar to that of the example was obtained. When the printed matter was irradiated with ultraviolet light, almost no fluorescence was emitted around the letter "T" due to the bleeding of the fluorescent dye.

クの利点を有しつつ、不正を防止することができる。According to the permeable fluorescent ink according to the first aspect of the present invention, the colorant and the fluorescent dye are dispersed in a vehicle containing at least a resin component curable by irradiation with ultraviolet rays and a bleed accelerating liquid. In addition, since the bleed accelerating liquid hinders complete curing of the vehicle, bleeding is likely to occur. Therefore, it is possible to prevent illegality while having the advantage of the ultraviolet curable ink such as quick drying.
