Description

本発明は、偽造防止印刷物に関する。   The present invention relates to an anti-counterfeit printed matter.

近年、カラー複写機やプリンターなどの複写性能が大幅に向上し、高画質の複写が可能となっており、各種の有価証券類等の偽造を容易にしている。これを防止するため種々の偽造防止印刷物が提案されている。
例えば、印刷の濃度を部分的若しくは段階的に変化させた文字や図柄などが印刷され、複写機の濃度認識を誤読させる偽造防止印刷物や、網点や万線を利用して文字や図柄などが浮き上がって見えるようにした偽造防止印刷物などが挙げられる。
しかし、デザインや使用できる色に制限があり、また高画質の複写性能を有するカラー複写機が普及しており、前記した偽造防止印刷物では偽造を防ぐことができない場合がある。
また、デザインに影響を与えない偽造防止印刷物としては、パール印刷,ホログラム印刷,厚盛り印刷,立体視印刷などの技術を用いて印刷されたものが挙げられる。しかし、いずれも印刷に係る材料が高価であり、また特殊な印刷技術が必要であり、偽造防止印刷物が高価となってしまう問題がある。
前記した偽造防止印刷物としては、以下の特許文献1,2などが挙げられる。
In recent years, the copying performance of color copiers and printers has greatly improved, enabling high-quality copying, and facilitating the forgery of various securities. In order to prevent this, various anti-counterfeit printed matter has been proposed.
For example, characters or designs that have been printed with partial or step-by-step changes in printing density are printed, and anti-counterfeit printed matter that misreads the density recognition of copiers, or characters or designs that use halftone dots or lines. Examples include anti-counterfeit printed matter that can be lifted up.
However, there are restrictions on the design and colors that can be used, and color copiers having high-quality copying performance have become widespread, and forgery cannot be prevented by the forgery-preventing printed matter described above.
Examples of the forgery-preventing printed matter that does not affect the design include those printed using techniques such as pearl printing, hologram printing, thick printing, and stereoscopic printing. However, in any case, materials for printing are expensive, and a special printing technique is required, and there is a problem that the forgery prevention printed matter becomes expensive.
Examples of the forgery-preventing printed material include the following Patent Documents 1 and 2.

また、偽造防止印刷物として、紫外線又は赤外線の照射により発光する蛍光物質を含有する印刷層が設けられたものも提案されている(特許文献3,4参照。)。この偽造防止印刷物では、紫外線又は赤外線を照射することによって、蛍光物質が発光し、真偽判定できるようになっている。
しかし、この蛍光物質を含有する印刷層が設けられた偽造防止印刷物では、ブラックライトや赤外線レーザなどの専用の光源を用いて、蛍光物質が発光するかどうか確認するようになっており、例えばカラー複写機などによる複写を防止することは考慮されていないのが現状である。

Moreover, what was provided with the printing layer containing the fluorescent material light-emitted by irradiation of an ultraviolet-ray or infrared rays as a forgery prevention printed matter is proposed (refer patent documents 3 and 4). In this anti-counterfeit printed matter, the fluorescent material emits light when irradiated with ultraviolet rays or infrared rays, and authenticity can be determined.
However, in the anti-counterfeit printed matter provided with the printing layer containing the fluorescent material, a dedicated light source such as a black light or an infrared laser is used to check whether the fluorescent material emits light. At present, it is not considered to prevent copying by a copying machine or the like.

That is, an object is to provide a forgery-preventing printed matter that can be prevented from being copied by a color copying machine or the like and that can be manufactured at low cost using an existing printing apparatus without affecting the design.

すなわち、本発明に係る偽造防止印刷物は、シート材の表面に、該シート材と同系色の蛍光体が設けられてなる偽造防止印刷物であって、前記蛍光体は、赤外線によって励起され、可視光領域の光を発光することを特徴としている。   That is, the anti-counterfeit printed matter according to the present invention is an anti-counterfeit printed matter in which a phosphor having the same color as that of the sheet material is provided on the surface of the sheet material, and the phosphor is excited by infrared rays and has visible light. It is characterized by emitting light in the region.

また、本発明に係る偽造防止印刷物の他の形態は、シート材の表面に、該シート材と同系色の蛍光体が設けられてなる偽造防止印刷物であって、前記蛍光体は、紫外線によって励起され、可視光領域の光を発光することを特徴としている。   Another form of the anti-counterfeit printed matter according to the present invention is an anti-counterfeit printed matter in which a phosphor of the same color as the sheet material is provided on the surface of the sheet material, and the phosphor is excited by ultraviolet rays.

また、シート材と同系色の蛍光体が設けられたことによって、室内光や自然光のもとでは蛍光体を視認できず、優れた安全性が実現できる。また、デザインに影響を与えることがなく、意匠性に優れ、種々の印刷物に適用できる。
また、蛍光体は比較的安価であり、かつ既存の装置を用い、公知の方法によってシート材に設けることができるため、安価な偽造防止印刷物を製造できる。
According to the anti-counterfeit printed matter according to the present invention, the anti-counterfeit printed matter is printed by a copying machine by providing a phosphor that emits visible light efficiently excited by infrared rays or ultraviolet rays on the surface of the sheet material. At this time, the phosphor is excited by the light of the lamp to emit visible light, and only the copy different from the printed information can be obtained by the light of the phosphor, and the copy of the print can be prevented.
Further, since the phosphor of the same color as the sheet material is provided, the phosphor cannot be visually recognized under room light or natural light, and excellent safety can be realized. Moreover, it does not affect the design, is excellent in design, and can be applied to various printed materials.
Moreover, since the phosphor is relatively inexpensive and can be provided on the sheet material by a known method using an existing apparatus, an inexpensive anti-counterfeit printed matter can be manufactured.

図1は、本発明の偽造防止印刷物1の一例を示す模式図である。本発明の偽造防止印刷物1は、シート材2の表面21に、シート材2と同系色の蛍光体3が設けられてなるものである。
前記シート材2としては、例えば、上質紙,OCR紙,ノーカーボン紙,アート紙などの紙類や、塩化ビニル,ポリエステル,PET,ポリプロピレン,セロファン,アセテート,ポリカーボネート,アクリルなどのプラスチックフィルムなどが挙げられる。
このシート材2の表面21には、図柄,模様,文字情報などの印刷層4が印字、印刷されている。
FIG. 1 is a schematic diagram illustrating an example of a forgery-preventing printed material 1 according to the present invention. The anti-counterfeit printed matter 1 of the present invention is such that a phosphor 3 having the same color as the sheet material 2 is provided on the surface 21 of the sheet material 2.
Examples of the sheet material 2 include paper such as high-quality paper, OCR paper, carbonless paper, and art paper, and plastic films such as vinyl chloride, polyester, PET, polypropylene, cellophane, acetate, polycarbonate, and acrylic. It is done.
On the surface 21 of the sheet material 2, a printing layer 4 such as a pattern, a pattern, and character information is printed and printed.

蛍光体3は、シート材2の表面21、すなわち図柄,模様,文字情報などの印刷層4が印字,印刷可能な面に設けられており、シート材2上に直接、蛍光体印刷層31として設けられている。
蛍光体3を蛍光体印刷層31としてシート材2上に直接、設ける方法としては、例えば蛍光体3をバインダー樹脂などと混合してインキ化し、公知の印刷法によりシート材2の表面21に塗布、乾燥する方法や、シート材2の表面21の加工工程において、顔料や接着剤と共に蛍光体3をシート材2の表面21に塗工する方法などが挙げられる。
The phosphor 3 is provided on the surface 21 of the sheet material 2, that is, a surface on which a printing layer 4 such as a pattern, a pattern, and character information can be printed and printed, and directly on the sheet material 2 as a phosphor printing layer 31. Is provided.
As a method of providing the phosphor 3 directly on the sheet material 2 as the phosphor printing layer 31, for example, the phosphor 3 is mixed with a binder resin to form an ink and applied to the surface 21 of the sheet material 2 by a known printing method. Examples thereof include a drying method and a method of applying the phosphor 3 to the surface 21 of the sheet material 2 together with a pigment and an adhesive in the processing step of the surface 21 of the sheet material 2.

なお、蛍光体3は、印刷層4上に設けられていても構わない。この場合、蛍光体印刷層31を透して印刷層4の図柄,模様,文字情報などが視認できるように、蛍光体印刷層31中の蛍光体3の含有量などを調整しておく。
また、シート材2として紙類を用いる場合、蛍光体3が含有されたシート材2としても構わない。例えばシート材2を製造する工程のうち抄紙工程において、パルプ溶液に蛍光体3を添加して常法により漉くことによって、蛍光体3が含有されたシート材2とすることができる。
また、蛍光体3は、図1に示されたように、シート材2の表面21に、文字として設けられていても構わないが、格子状,斜線形,波形などの筋状、円,楕円,矩形,多角形,星形などの図柄,模様として設けられたり、シート材2全面に設けられていても構わない。
The phosphor 3 may be provided on the printing layer 4. In this case, the content of the phosphor 3 in the phosphor print layer 31 is adjusted so that the design, pattern, character information, etc. of the print layer 4 can be seen through the phosphor print layer 31.
When paper is used as the sheet material 2, the sheet material 2 containing the phosphor 3 may be used. For example, in the paper making process in the process of manufacturing the sheet material 2, the phosphor material 3 is added to the pulp solution, and the sheet material 2 is dispersed by a conventional method, whereby the sheet material 2 containing the phosphor 3 can be obtained.
Further, as shown in FIG. 1, the phosphor 3 may be provided as a character on the surface 21 of the sheet material 2. , A rectangle, a polygon, a star, or the like, or provided on the entire surface of the sheet material 2.

蛍光体3は、通常、白色又は淡色の粉末であるため、白色のシート材2に設けた場合、蛍光体3はシート材2と同系色となり、室内光や自然光のもとでは蛍光体3を視認できないようになっている。また、蛍光体3とシート材2が異なる色であっても、蛍光体3に顔料粉末を混合することによって、蛍光体3をシート材2と同系色とすることができる。   Since the phosphor 3 is usually a white or light-colored powder, when the phosphor 3 is provided on the white sheet material 2, the phosphor 3 has the same color as the sheet material 2, and the phosphor 3 is used under room light or natural light. It is not visible. Moreover, even if the phosphor 3 and the sheet material 2 are different colors, the phosphor 3 can be made the same color as the sheet material 2 by mixing the phosphor 3 with pigment powder.

前記蛍光体3としては、紫外線によって励起し、可視光領域の光を発光する紫外線励起蛍光体や、赤外線によって励起し、可視光領域の光を発光する赤外線励起蛍光体が挙げられる。
紫外線励起蛍光体としては、Y:Eu(発光波長:620〜630nm)、ZnS:Cu(発光波長:530〜540nm)、ZnS:Al(発光波長:445〜455nm)などの350nm付近の紫外線によって励起するものなどが挙げられる。
また、赤外線励起蛍光体としては、YF:Yb+Er(発光色:緑〜赤)、YF:Yb+Tm(発光色:青)などのYb3+,Er3+,Ho3+を賦活剤とした希土類蛍光体などが挙げられる。
ここで、本明細書中、蛍光体3は、主成分である母体結晶の化学式の後に(:)を設け、(:)の後に、母体結晶中に分散させた賦活剤又は発光中心を記載して表わす。
Examples of the phosphor 3 include an ultraviolet excitation phosphor that is excited by ultraviolet rays and emits light in the visible light region, and an infrared excitation phosphor that is excited by infrared rays and emits light in the visible light region.
As the ultraviolet-excited phosphor, Y 2 O 3 : Eu (emission wavelength: 620 to 630 nm), ZnS: Cu (emission wavelength: 530 to 540 nm), ZnS: Al (emission wavelength: 445 to 455 nm), etc. Examples include those excited by ultraviolet rays.

特に本発明では、シート材2に設けられた蛍光体3が、複写機に用いられるランプの光によって効率良く励起されて可視光を発光するように、平均粒子径,粒度分布などの粉体特性や蛍光体3の組成比などが調整されていることが好ましい。
これにより、偽造防止印刷物1が複写機にて複写された際、シート材2に設けられた蛍光体3が、複写機のランプの光によって励起されて可視光を発光し、この蛍光体3の光によって印刷層4の図柄,模様,文字情報とは異なる複写物しか得られないようにすることができ、偽造防止印刷物1の複写を防止できる。
In particular, in the present invention, powder characteristics such as average particle diameter and particle size distribution are emitted so that the phosphor 3 provided on the sheet material 2 is efficiently excited by the light of a lamp used in a copying machine and emits visible light. It is preferable that the composition ratio of phosphor and phosphor 3 is adjusted.
Thereby, when the anti-counterfeit printed matter 1 is copied by the copying machine, the phosphor 3 provided on the sheet material 2 is excited by the light of the lamp of the copying machine to emit visible light. Only a copy different from the pattern, pattern, and character information of the print layer 4 can be obtained by light, and the copy of the forgery prevention print 1 can be prevented.

通常、複写機にはハロゲンランプ又はキセノンランプが使用されている。図2は、ハロゲンランプ又はキセノンランプの放射スペクトルの一例を示す図である。また、図3は、複写機用に分光特性が調整されたハロゲンランプの放射スペクトルを示す図である。図4は、複写機用に分光特性が調整されたキセノンランプのランプ電力を一定にしたときの放射スペクトルを示す図である。
ハロゲンランプの放射スペクトルでは、ランプ温度によって放射ピークが変動するが、900〜1400nmにて放射強度が最大となり、500〜2500nmに渡って広く分布した放射スペクトルであることが分かる。
これに対して、キセノンランプの放射スペクトルでは、複数の放射ピークがあることが分かる。
このハロゲンランプとキセノンランプの放射スペクトルにおいて、赤外領域の830nmと880nmの近傍にて、共に高強度の放射光が得られることが分かる。
Usually, a halogen lamp or a xenon lamp is used in the copying machine. FIG. 2 is a diagram illustrating an example of a radiation spectrum of a halogen lamp or a xenon lamp. FIG. 3 is a diagram showing a radiation spectrum of a halogen lamp with spectral characteristics adjusted for a copying machine. FIG. 4 is a diagram showing a radiation spectrum when the lamp power of a xenon lamp whose spectral characteristics are adjusted for a copying machine is made constant.
In the radiation spectrum of the halogen lamp, the radiation peak varies depending on the lamp temperature, but it can be seen that the radiation intensity becomes maximum at 900 to 1400 nm and is widely distributed over 500 to 2500 nm.
On the other hand, it can be seen that there are a plurality of radiation peaks in the radiation spectrum of the xenon lamp.
In the emission spectra of the halogen lamp and the xenon lamp, it can be seen that high intensity radiated light is obtained in the vicinity of 830 nm and 880 nm in the infrared region.

以上により、シート材2に設ける蛍光体3としては、その励起スペクトルの吸収ピークが830nm又は880nmにあり、複写機に用いられるハロゲンランプ又はキセノンランプの光によって効率良く励起されて可視光を発光するものを用いる。
具体的には、蛍光体3として、ZrF:Er3+又はZrF:Tm3+を用いることによって、複写機に用いられるハロゲンランプ又はキセノンランプの光によって効率良く励起されて可視光を発光させることができる。
特に、賦活剤となるEr3+,Tm3+の含有量は0.001〜1%が好ましく、また平均粒径は0.5〜1.5μmが好ましい。これにより、ハロゲンランプ又はキセノンランプの光によって、より効率良く励起されて高輝度の可視光を発光させることができる。
As described above, the phosphor 3 provided in the sheet material 2 has an excitation spectrum absorption peak at 830 nm or 880 nm, and is excited efficiently by the light of a halogen lamp or xenon lamp used in a copying machine to emit visible light. Use things.
Specifically, by using ZrF 4 : Er 3+ or ZrF 4 : Tm 3+ as the phosphor 3, it is excited efficiently by the light of the halogen lamp or xenon lamp used in the copying machine and emits visible light. Can do.
In particular, the content of Er 3+ and Tm 3+ serving as activators is preferably 0.001 to 1%, and the average particle size is preferably 0.5 to 1.5 μm. Accordingly, it is possible to emit visible light with high luminance by being excited more efficiently by the light of the halogen lamp or the xenon lamp.

前述した蛍光体3が設けられたシート材2の表面21に、所定の図柄,模様,文字情報などの印刷層4を印字、印刷することによって偽造防止印刷物1とすることができる。
この偽造防止印刷物1では、蛍光体3がシート材2と同系色であるため、室内光や自然光のもとでは蛍光体3を視認できず、シート材2に印刷された所定の図柄,模様,文字情報などの印刷層4の印刷情報のみが視認される。
偽造防止印刷物1を複写機で印刷する際、シート材2に設けられた蛍光体3が複写機のランプの光によって励起されて可視光を発光し、この蛍光体3の光によって印刷層4の印刷情報とは異なる複写物しか得られない。このように複写機で複写する際、蛍光体3が発光して偽造防止印刷物1の複写が防止される。
A forgery-preventing printed matter 1 can be obtained by printing and printing a printing layer 4 such as predetermined patterns, patterns, and character information on the surface 21 of the sheet material 2 provided with the phosphor 3 described above.
In this anti-counterfeit printed matter 1, since the phosphor 3 has the same color as the sheet material 2, the phosphor 3 cannot be visually recognized under room light or natural light, and a predetermined pattern, pattern, or pattern printed on the sheet material 2. Only print information of the print layer 4 such as character information is visually recognized.
When the anti-counterfeit printed matter 1 is printed by a copying machine, the phosphor 3 provided on the sheet material 2 is excited by the light of the lamp of the copying machine and emits visible light. Only a copy different from the printed information can be obtained. In this way, when copying with a copying machine, the phosphor 3 emits light and the copy of the forgery prevention printed matter 1 is prevented.

本発明の偽造防止印刷物1によれば、複写機に用いられるランプの放射スペクトルのうち、赤外線又は紫外線によって効率良く励起されて可視光を発光する蛍光体3がシート材2の表面21に設けられたことによって、偽造防止印刷物1が複写機にて印刷された際、蛍光体3がランプの光によって励起されて可視光を発光し、この蛍光体3の光によって印刷層4の印刷情報とは異なる複写物しか得られないようにすることができ、偽造防止印刷物1の複写を防止できる。   According to the anti-counterfeit printed matter 1 of the present invention, the phosphor 3 that emits visible light by being efficiently excited by infrared rays or ultraviolet rays out of the emission spectrum of a lamp used in a copying machine is provided on the surface 21 of the sheet material 2. Thus, when the anti-counterfeit printed matter 1 is printed by the copying machine, the phosphor 3 is excited by the light of the lamp to emit visible light, and the printing information of the printing layer 4 is emitted by the light of the phosphor 3. Only different copies can be obtained, and copying of the anti-counterfeit printed matter 1 can be prevented.

また、蛍光体3は、顔料と混合することによって所望の色に着色することも可能であり、容易に偽造防止印刷物1の基材となるシート材2と同系色とすることができる。このため、従来の網点や万線を利用して文字や図柄などが浮き上がって見えるようにした偽造防止印刷物とは異なり、室内光や自然光のもとでは蛍光体3を視認できず、優れた安全性が実現できる。また、デザインに影響を与えることがなく、意匠性に優れ、種々の印刷物に適用できる。
特に、蛍光体3は、通常、白色又は淡色であるため、PPC用紙などの白色のシート材2にも適用できる。
また、蛍光体3は比較的安価であり、かつ既存の装置を用い、公知の方法によってシート材2に設けることができる。特に、白色のシート材2に白色の蛍光体3を設ける場合、他の顔料などを用いる必要がなく、蛍光体3のみでよいため、ほとんどコストアップにならず、通常の印刷物とほぼ同等の価格とすることができる。このように安価な偽造防止印刷物1を製造できる。
Further, the phosphor 3 can be colored in a desired color by mixing with a pigment, and can easily have the same color as the sheet material 2 that becomes the base material of the anti-counterfeit printed matter 1. For this reason, unlike the anti-counterfeit printed matter in which characters and designs are made visible by using halftone dots and lines, the phosphor 3 cannot be visually recognized under room light or natural light. Safety can be realized. Moreover, it does not affect the design, is excellent in design, and can be applied to various printed materials.
In particular, since the phosphor 3 is usually white or light in color, it can be applied to a white sheet material 2 such as PPC paper.
Further, the phosphor 3 is relatively inexpensive and can be provided on the sheet material 2 by a known method using an existing apparatus. In particular, when the white phosphor 3 is provided on the white sheet material 2, it is not necessary to use other pigments, and only the phosphor 3 is required, so that the cost is hardly increased and the price is almost the same as that of a normal printed material. It can be. Thus, the cheap anti-counterfeit printed matter 1 can be manufactured.

なお、本発明の技術範囲は、上記の実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば、本発明の偽造防止印刷物1は、図1に示された預り証に限定されず、印刷層4の図柄,模様,文字情報やシート材2を適宜選択することによって、手形,小切手,株券,債券,船荷証券,倉庫証券,貨物引換証,商品券などの有価証券、パスポート、紙幣,通行証,投票用紙などに適用できる。
