Description

本発明は、所定の情報と光回折構造とが含まれた記録物の製造方法及び記録物に関する。   The present invention relates to a method for manufacturing a recorded matter including predetermined information and a light diffraction structure, and a recorded matter.

所定の情報と光回折構造とが含まれた記録物の製造方法として、例えば被転写体に所定の情報を先に印刷しておき、その情報上へ被転写体へ光回折構造転写シートの光回折構造が設けられた層を転写する方法が知られている（例えば特許文献１）。   As a manufacturing method of a recorded matter including predetermined information and a light diffractive structure, for example, predetermined information is first printed on a transfer object, and the light of the light diffraction structure transfer sheet is transferred onto the information. A method of transferring a layer provided with a diffractive structure is known (for example, Patent Document 1).

特開平８−１１８８５７JP-A-8-118857

しかし、上述した方法は、光回折構造の製造や復元の困難性に着目して情報の偽造防止を主な目的とするものだが、光回折構造に関する技術が発達した昨今では、偽造を防止すべき情報上に光回折構造を単に転写するだけではセキュリティ上完全であるとは言い難くなっている。   However, the above-mentioned method is mainly intended to prevent forgery of information by paying attention to the difficulty of manufacturing and restoring the light diffractive structure. It is difficult to say that the light diffraction structure is simply transferred onto the information so that the security is perfect.

そこで、本発明は、光回折構造を利用して情報の偽造や改ざん等を防止するためのより高度なセキュリティを実現する記録物製造方法等を提供することを目的とする。   Therefore, an object of the present invention is to provide a recorded matter manufacturing method that realizes higher security for preventing forgery or alteration of information using an optical diffraction structure.

本発明の記録物製造方法は、情報（２）が可視光線によって視認できないインクによって記録された被転写体（１０）上に、光回折構造転写シート（２０）に設けられた光回折構造を含む層（２０ｄ）を転写することにより、前記記録された情報と前記光回折構造とが含まれた記録物（１）を製造する方法であって、前記光回折構造を含む層は、転写される前記光回折構造が前記記録された情報との対応関係において所定の規則性を示す情報（５）を形成する形状となるように、転写されることにより、上記の課題を解決する。 The recorded matter manufacturing method of the present invention includes a light diffractive structure provided on a light diffractive structure transfer sheet (20) on a transfer target (10) on which information (2) is recorded with ink that cannot be visually recognized by visible light. A method for producing a recorded matter (1) including the recorded information and the light diffraction structure by transferring a layer (20d), wherein the layer including the light diffraction structure is transferred The above-mentioned problem is solved by transferring the light diffraction structure so as to form a shape that forms information (5) indicating a predetermined regularity in correspondence with the recorded information.

本発明によれば、記録物における既に記録された情報と転写された光回折構造との間に所定の規則性を生じさせることができるため、記録された情報を改ざんしようとした場合、光回折構造による情報も当該規則性を満たすようにに改ざんしなければならない。従って、光回折構造を単に復元や製造するよりも更に改ざんや偽造を困難にすることができ、より高度なセキュリティを実現できる。また、被転写体に予め記録される情報の内容が変わっても、その情報に応じた内容の情報を転写すればよいので、情報の幅が広がり、様々な用途に利用することができる。また、前記記録された情報は可視光線では視認できないインクで印刷されているので、可視光線下では記録された情報は視認されず、紫外線等の可視光線以外の光線によってのみ認知することができるため、より高度なセキュリティを実現することができる。 According to the present invention, a predetermined regularity can be generated between information already recorded in the recorded matter and the transferred light diffraction structure. Therefore, when attempting to tamper with the recorded information, Structural information must also be altered to satisfy the regularity. Therefore, it is possible to make tampering and counterfeiting more difficult than simply restoring or manufacturing the light diffraction structure, and higher security can be realized. In addition, even if the content of information recorded in advance on the transfer medium changes, it is only necessary to transfer the information according to the information, so the width of the information is widened and it can be used for various purposes. In addition, since the recorded information is printed with ink that is not visible with visible light, the recorded information is not visible under visible light and can be recognized only by light other than visible light such as ultraviolet rays. Higher security can be realized.

「所定の規則性」とは、同一の記録物上に含まれる、即ち対応付けられた記録された情報と光回折構造が形成する情報とが直接特定の関係を有している場合のみならず、複数の記録物間における各記録された情報と各光回折構造が形成する情報とから導き出すことができる規則性も含む。光回折構造の転写方法は、当該所定の規則性を有する情報を形成するように転写できる方法であれば、熱転写、レーザー光等種類を問わない。光回折構造とは所定の形状を形成する干渉縞であるホログラムと一様の凹凸パターンである回折格子とを含む。   The “predetermined regularity” is not limited to the case where the information recorded on the same recorded material, that is, the recorded information associated with the information formed by the light diffraction structure has a specific relationship directly. Also included is regularity that can be derived from information recorded between a plurality of recorded materials and information formed by each light diffraction structure. The transfer method of the light diffraction structure may be any type, such as thermal transfer and laser light, as long as the transfer can be performed so as to form information having the predetermined regularity. The light diffraction structure includes a hologram that is an interference fringe that forms a predetermined shape and a diffraction grating that is a uniform uneven pattern.

本発明の記録物（１）は、情報（２）が可視光線によって視認できないインクによって記録された被転写体（１０）上に、光回折構造転写シート（２０）に設けられた光回折構造を含む層（２０ｄ）が所定の情報を示す形状で転写されることにより得られる、前記記録された情報と前記光回折構造（３、４、５）とが含まれた記録物であって、前記記録された情報と転写された前記光回折構造とによって形成された情報（５）とが、所定の規則性を生じるように対応付けられていることにより上記の課題を解決する。 The recorded matter (1) of the present invention has a light diffractive structure provided on a light diffractive structure transfer sheet (20) on a transfer target (10) on which information (2) is recorded with ink that cannot be visually recognized by visible light. A recorded matter including the recorded information and the light diffraction structure (3, 4, 5) obtained by transferring the layer (20d) including the information in a shape indicating predetermined information , The above problem is solved by associating the recorded information and the information (5) formed by the transferred light diffraction structure so as to produce a predetermined regularity.

本発明によれば、記録物に転写された光回折構造が記録された情報と所定の規則性を有するように対応付けられているので、上述したようにより高度なセキュリティを提供することができる。また、前記記録された情報と転写された前記光回折構造によって形成された情報とがシンクロしていてもよい。これにより、光回折構造によって形成される情報を既に記録された情報にシンクロさせるだけでより高度なセキュリティを提供することができる。シンクロする情報とは、記録された情報と視覚的、聴覚的又は観念的に一致する情報をいう。観念的に一致するとは、例えば日本語とその英訳等、同じ物が連想可能な関係をいう。   According to the present invention, since the light diffraction structure transferred to the recorded matter is associated with the recorded information so as to have a predetermined regularity, higher security can be provided as described above. The recorded information and the information formed by the transferred light diffraction structure may be synchronized. Thereby, it is possible to provide a higher level of security simply by synchronizing the information formed by the light diffraction structure with the already recorded information. Synchronized information refers to information that visually, audibly, or conceptually matches the recorded information. Ideally matching means a relationship where the same thing can be associated, such as Japanese and its English translation.

以上のように、本発明は、光回折構造転写シートに設けられた光回折構造を、既に被転写体上に記録された情報との対応関係において所定の規則性を示す情報を形成するように転写することにより、光回折構造を利用して情報の偽造や改ざん等を防止するためのより高度なセキュリティを実現する記録物の製造方法等を提供することができる。   As described above, according to the present invention, the light diffractive structure provided on the light diffractive structure transfer sheet forms information indicating a predetermined regularity in correspondence with information already recorded on the transfer target. By transferring, it is possible to provide a method of manufacturing a recorded material that realizes higher security for preventing forgery or falsification of information by using an optical diffraction structure.

図１は本形態において製造する記録物１としてのシールを示す図である。記録物１には記録された情報として日付が印刷された印刷情報部２、形状「Ａ」に３次元ホログラムが施されたホログラム部３、横縞状の回折格子が施された回折格子部４、印刷情報部２と同じ日付が回折格子によって形成された回折格子情報部５とが含まれる。以下、記録物１を製造する方法について説明する。   FIG. 1 is a view showing a seal as a recorded product 1 manufactured in this embodiment. Printed information portion 2 on which date is printed as recorded information on recorded matter 1, hologram portion 3 on which shape “A” is given a three-dimensional hologram, diffraction grating portion 4 on which a horizontal stripe-like diffraction grating is given, A diffraction grating information section 5 in which the same date as the print information section 2 is formed by a diffraction grating is included. Hereinafter, a method for manufacturing the recorded matter 1 will be described.

本形態における被転写体１０は、図２に示すように既に印刷情報部２が設けられている。この被転写体１０へ光回折構造転写シートに設けられた光回折構造をサーマルヘッドによって熱転写することにより、記録物１を製造する。本形態における光回折構造転写シート２０の構造を図３及び図４に示す。図３に示すように、光回折構造転写シート２０は、サーマルヘッドが当てられる側から順に背面滑性層２０ａ、基材シート２０ｂ、剥離層２０ｃ、及び光回折構造形成層２０ｄが積層されて構成される。   As shown in FIG. 2, the print information unit 2 is already provided on the transfer target 10 in this embodiment. The recorded product 1 is manufactured by thermally transferring the light diffractive structure provided on the light diffractive structure transfer sheet to the transfer target 10 by a thermal head. The structure of the light diffraction structure transfer sheet 20 in this embodiment is shown in FIGS. As shown in FIG. 3, the light diffraction structure transfer sheet 20 is configured by laminating a back slip layer 20a, a base sheet 20b, a release layer 20c, and a light diffraction structure forming layer 20d in order from the side to which the thermal head is applied. Is done.

本発明における光回折構造とは回折格子又はホログラムを意味し、光回折構造形成層２０ｄに形成されている。図４に示すように本形態の光回折構造形成層２０ｄは、回折格子箔２０ｄ−１で全体が構成され、３Ｄの計算機ホログラムが施された形状「Ａ」を示すホログラム部２０ｄ−２が一定間隔で設けられている。回折格子箔２０ｄ−１及びホログラム部２０ｄ−２が後述する方法によって被転写体１０へ転写されて記録物１のホログラム部３や回折格子情報部５をそれぞれ形成する。   The light diffraction structure in the present invention means a diffraction grating or a hologram, and is formed in the light diffraction structure forming layer 20d. As shown in FIG. 4, the optical diffraction structure forming layer 20d of this embodiment is entirely composed of a diffraction grating foil 20d-1, and a hologram portion 20d-2 showing a shape “A” subjected to a 3D computer generated hologram is constant. It is provided at intervals. The diffraction grating foil 20d-1 and the hologram part 20d-2 are transferred to the transfer target 10 by a method described later to form the hologram part 3 and the diffraction grating information part 5 of the recorded material 1, respectively.

光回折構造形成層２０ｄに設けられる回折格子及びホログラムの干渉縞は、表面に凹凸パターンを有するレリーフとして記録されているもの、厚み方向に立体的に記録されているもの、又は透過率の変化による光の振幅の変化で回折が起こるように記録されているもののいずれであってもよい。具体的には、フレネルホログラム、イメージホログラム等のレーザー再生ホログラム、リップマンホログラム、レインボーホログラム等の白色光再生ホログラム、これらの原理を利用したホログラフィックスステレオグラム、カラーホログラム等がある。   The diffraction grating and hologram interference fringes provided on the optical diffraction structure forming layer 20d are recorded as reliefs having a concavo-convex pattern on the surface, recorded three-dimensionally in the thickness direction, or due to a change in transmittance. Any of those recorded so that diffraction occurs due to a change in the amplitude of light may be used. Specifically, there are laser reproduction holograms such as Fresnel holograms and image holograms, white light reproduction holograms such as Lippmann holograms and rainbow holograms, holographic stereograms utilizing these principles, color holograms, and the like.

これらのホログラムは従来既知の方法によって製造し光回折構造形成層２０ｄとすればよい。また、光回折構造形成層２０ｄは、被転写体１０に接着する接着性を有していてもよい。接着性を生じさせるための素材は被転写体１０の表面を構成する素材に応じて適宜決めればよい。尚、光回折構造形成層２０ｄを構成する材料は被転写体１０へ転写された際に、印刷情報２が完全に隠蔽されないような大きさ（ドット）で印字することにより印刷情報２を完全に隠蔽することがない。   These holograms may be manufactured by a conventionally known method to form the light diffraction structure forming layer 20d. Further, the light diffraction structure forming layer 20 d may have adhesiveness that adheres to the transfer target 10. The material for causing the adhesiveness may be appropriately determined according to the material constituting the surface of the transfer target 10. The material constituting the optical diffraction structure forming layer 20d is printed in such a size (dot) that the print information 2 is not completely concealed when it is transferred to the transfer target 10, so that the print information 2 is completely obtained. There is no concealment.

背面滑性層２０ａは、加熱によるいわゆるスティッキング現象の発生を防止するために設けられている。従って耐熱性、熱スベリ性の高いものであることが要求される。剥離層２０ｃは、光回折構造形成層２０ｄと基材シート２０ｂとの剥離性を高めるために設けられている。構成する材料は基材シート２０ｂに応じて適宜決めればよい。基材シート２０ｂはある程度の剛性と耐熱性を有するものであればよい。光回折構造転写シート２０の全体の厚みは、サーマルヘッドからの熱伝導が阻害されない程度の厚みであることが好ましい。   The back sliding layer 20a is provided to prevent the occurrence of a so-called sticking phenomenon due to heating. Accordingly, it is required to have high heat resistance and heat slip. The release layer 20c is provided in order to improve the peelability between the light diffraction structure forming layer 20d and the base sheet 20b. What is necessary is just to determine the material to comprise suitably according to the base material sheet 20b. The base sheet 20b only needs to have a certain degree of rigidity and heat resistance. The total thickness of the light diffraction structure transfer sheet 20 is preferably a thickness that does not hinder thermal conduction from the thermal head.

上述した構成を有する光回折構造転写シート２０の光回折構造形成層２０ｄ側と被転写体１０の表面とを重ね合わせ、サーマルヘッドによって背面滑性層２０ａ側から加熱する。加熱された部分に対応する剥離層２０ｃが基材シート２０ｂから剥離して光回折構造形成層２０ｄが被転写体１０へ転写する。即ち、サーマルヘッドによる加熱位置に対応する光回折構造形成層２０ｄが被転写体１０へ転写される。従って、背面滑性層２０ａに対して所定の面積をまんべんなく加熱すれば、その加熱位置に対応する所定の面積を有する光回折構造形成層２０ｄが転写し、所定の形状を描くように加熱すれば、その加熱位置に対応する所定の形状を描くように光回折構造形成層２０ｄが転写する。   The light diffraction structure forming layer 20d side of the light diffraction structure transfer sheet 20 having the above-described structure is superposed on the surface of the transfer target 10, and heated from the back sliding layer 20a side by a thermal head. The release layer 20c corresponding to the heated portion is peeled from the base material sheet 20b, and the light diffraction structure forming layer 20d is transferred to the transfer body 10. That is, the optical diffraction structure forming layer 20 d corresponding to the heating position by the thermal head is transferred to the transfer target 10. Therefore, if the back slip layer 20a is heated evenly over a predetermined area, the light diffraction structure forming layer 20d having a predetermined area corresponding to the heating position is transferred and heated so as to draw a predetermined shape. The light diffraction structure forming layer 20d transfers so as to draw a predetermined shape corresponding to the heating position.

本形態では、まず、ホログラム部２０ｄ−２に対応する範囲を背面滑性層２０ａ側からサーマルヘッドによって満遍なく加熱する。これにより、ホログラム部２０ｄ−２に対応する光回折構造形成層２０ｄが被転写体１０へを転写され、ホログラム部３を形成する。このようすを図５に示す。この場合、ホログラム部２０ｄ−２に対応する範囲内で１つのサーマルヘッドを満遍なく移動させて加熱してもよいし、複数の発熱子を有するサーマルヘッドによって当該範囲を一度に加熱してもよい。   In this embodiment, first, the range corresponding to the hologram portion 20d-2 is uniformly heated from the back sliding layer 20a side by the thermal head. Thereby, the light diffraction structure forming layer 20d corresponding to the hologram part 20d-2 is transferred onto the transfer target 10, and the hologram part 3 is formed. This is shown in FIG. In this case, one thermal head may be moved uniformly within the range corresponding to the hologram portion 20d-2 and heated, or the range may be heated at once by a thermal head having a plurality of heating elements.

次に、被転写体１０における回折格子部４及び回折格子情報部５に対応する部分に光回折構造形成層２０ｄの回折格子箔２０ｄ−１の部分が重なるように光回折構造転写シート２０を位置させる。サーマルヘッドの移動によって光回折構造転写シート２０の背面滑性層２０ａ側から横縞状に加熱することにより、光回折構造形成層２０ｄの回折格子箔２０ｄ−１が横縞状に転写され、回折格子部４を形成する。更に、印刷情報部２に示されている日付と同じ日付が転写されるようにサーマルヘッドを移動させる。上述したように加熱された部分に対応する光回折構造形成層２０ｄのみが転写されるので、印刷情報部２に示されている日付と同じ日付が回折格子によって表現された回折格子情報部５を形成する。以上の方法によって、記録物１を得ることができる。   Next, the optical diffraction structure transfer sheet 20 is positioned so that the part of the diffraction grating foil 20d-1 of the optical diffraction structure forming layer 20d overlaps the part corresponding to the diffraction grating part 4 and the diffraction grating information part 5 in the transferred object 10. Let The diffraction grating foil 20d-1 of the light diffraction structure forming layer 20d is transferred in a horizontal stripe shape by heating in the horizontal stripe shape from the back sliding layer 20a side of the light diffraction structure transfer sheet 20 by the movement of the thermal head. 4 is formed. Further, the thermal head is moved so that the same date as that shown in the print information section 2 is transferred. Since only the optical diffraction structure forming layer 20d corresponding to the heated portion is transferred as described above, the diffraction grating information section 5 in which the same date as the date shown in the print information section 2 is expressed by the diffraction grating is displayed. Form. The recorded matter 1 can be obtained by the above method.

本発明は、上述した形態に限らず種々の形態で実施してよい。例えば、印刷情報部２における情報の色は問わない。可視光で認識できないインクで印刷されていてもよい。また、印刷される情報は日付に限らず、文字、記号、図形、模様等種類を問わず用途に応じて適宜変更可能である。また、被転写体１０に記録された情報の記録方法は、印刷に限らず塗布、エッチング等種類は問わない。   The present invention is not limited to the above-described form and may be implemented in various forms. For example, the color of information in the print information unit 2 is not limited. It may be printed with ink that cannot be recognized by visible light. Further, the information to be printed is not limited to the date, and can be appropriately changed according to the application regardless of the type such as characters, symbols, figures, patterns and the like. Moreover, the recording method of the information recorded on the transfer target 10 is not limited to printing, and any type such as coating and etching may be used.

上述した形態では、ホログラム部３、回折格子部４、回折格子情報部５の順で形成したが、各部を形成する順序は問わない。記録物１は光回折構造以外の方法によって記録された情報と光回折構造によって記録された情報とを含むものであれば、シール、カード、金券類等、その用途は問わない。また、印刷情報２が既に印刷された被転写体１０に対して回折格子情報部５を転写する形態を示したが、被転写体上に印刷情報２が回折格子情報部５より順序が先に印刷されればよく、例えば、印刷情報２が印刷されていない被転写体に対して同じ機械で印刷情報２を先に印刷し、続いて回折格子情報部５を設けてもよい。回折格子情報部５は、いわゆる回折格子だけでなくホログラムで形成されていてもよい。   In the above-described embodiment, the hologram unit 3, the diffraction grating unit 4, and the diffraction grating information unit 5 are formed in this order, but the order of forming each unit is not limited. As long as the recorded material 1 includes information recorded by a method other than the light diffractive structure and information recorded by the light diffractive structure, the use thereof is not limited, such as a seal, a card, and a voucher. In addition, the mode in which the diffraction grating information unit 5 is transferred to the transfer target 10 on which the print information 2 has already been printed has been shown. However, the print information 2 is placed on the transfer target prior to the diffraction grating information unit 5. For example, the printing information 2 may be printed on the transfer body on which the printing information 2 is not printed, using the same machine, and then the diffraction grating information unit 5 may be provided. The diffraction grating information unit 5 may be formed of not only a so-called diffraction grating but also a hologram.

光回折構造転写シート２０には、光回折構造形成層２０ｄの剥離層２０ｃと反対側に、被転写体１０と接着性の高い接着層を設けてもよい。また、基材シート２０ｂに剥離性がある場合は剥離層は設けなくても良い。背面滑性層２０ａは、基材シート２０ｂの滑性が高く、加熱位置を十分移動できる時は設ける必要がない。また、光回折構造転写シート２０に可視光を遮蔽する可視光遮蔽層を設け、光回折構造形成層２０ｄと共に被転写体１０へ転写してもよい。これにより、光回折構造形成層２０ｄが転写された位置の下に記録されている情報は可視光下で視認できなくなり、例えば紫外線のみによって視認できる。従って、セキュリティ度をより高めることができる。光回折構造転写シート２０には、他に回折効率を高める層等、本発明を実現できる限り適宜積層可能である。   The light diffraction structure transfer sheet 20 may be provided with an adhesive layer having high adhesion to the transfer target 10 on the opposite side of the light diffraction structure forming layer 20d from the release layer 20c. Moreover, when the base material sheet 20b has peelability, the release layer may not be provided. The back slip layer 20a does not need to be provided when the base sheet 20b has a high slip and can move the heating position sufficiently. Further, a visible light shielding layer that shields visible light may be provided on the light diffraction structure transfer sheet 20, and the light diffraction structure transfer layer 20d may be transferred to the transfer target body 10. Thereby, the information recorded under the position where the light diffraction structure forming layer 20d is transferred cannot be visually recognized under visible light, and can be visually recognized only with ultraviolet rays, for example. Therefore, the security level can be further increased. The optical diffraction structure transfer sheet 20 can be appropriately laminated as long as the present invention can be realized, such as a layer for improving diffraction efficiency.

また、加熱方法としてはサーマルヘッドによる加熱である必要はなく、光回折構造形成層２０ｄを線状の形状にも面状の形状にも転写できる加熱方法であればよい。例えば、レーザー光による熱を利用してもよい。この場合は、光回折構造転写シート２０に背面滑性層２０ａは不要となり、代わりに光熱変換剤をいずれかの層に含ませるか又は光熱変換層を設けることが望ましい。   Further, the heating method need not be heating by a thermal head, and may be any heating method that can transfer the light diffraction structure forming layer 20d to a linear shape or a planar shape. For example, heat generated by laser light may be used. In this case, the back-sliding layer 20a is not necessary in the light diffraction structure transfer sheet 20, and it is desirable to include a light-heat conversion agent in any layer or provide a light-heat conversion layer instead.
