Description

【0001】
【発明の属する技術分野】
本発明は、使用者が受け取った段階では視覚情報が隠されている、視覚情報記録媒体および視覚情報の発現方法に関するものである。
【0002】
【従来の技術】
近年、さまざまな分野で視覚情報記録媒体が使用されている。例えば、1つの例として、スクラッチ方式の視覚情報記録媒体が上げられる。使用者が爪やコイン等で表面の隠蔽物を削り取ることで、隠されていた視覚情報を初めて確認することができるシートをスクラッチ(引っ掻き)用シートと称する。スクラッチ用シートを応用した製品としては、用紙の一部にスクラッチ部を設けたスクラッチカードが代表的である。スクラッチカードは、主に国際電話や携帯電話等に使用されるプリペイドカードとして広く用いられている。
【0003】
もう一つ例を上げると、抽選・くじ引き等におけるくじが上げられる。紙等の印刷基材上に視覚情報を印刷したものを2つ折りにし、重なり合う周辺部を接着する等して、印刷された視覚情報が外観からは知り得ることができないよう加工したものが用いられている。
【0004】
【発明が解決しようとする課題】
しかしながら、スクラッチ方式に関しては、下地の視覚情報をスクラッチ層で完全に隠蔽することが容易ではないため、隠蔽性を上げる目的でスクラッチ層を厚塗り、時には多層塗りしたり、スクラッチ層上に地紋層を印刷し、下地の視覚情報を見え難くしたりすることが必要となり、コスト増加につながっていた。また、くじに関しては、視覚情報を単に印刷しただけの従来のくじにおいては、その印刷された視覚情報に手が加えられ、くじが偽造あるいは改竄され易い問題を有していた。
【0005】
本発明は、上記の欠点を除去し、使用前の状態で視覚情報を認知することが極めて困難で、更に偽造・改竄を防止できる視覚情報記録媒体とその視覚情報発現方法を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明によれば、支持体上に紫外線硬化型インクを積層し、硬化を行わずに、少なくとも片面が離型処理された対向支持体を、離型面が紫外線硬化型インクと接するように積層した構成を有し、両側支持体のうち、少なくとも片側が紫外線を透過する材質を使用している視覚情報記録媒体が得られる。
【0007】
また、本発明によれば、前記の媒体に、紫外線を透過する支持体側から、視覚情報として利用したい形状に、部分的に紫外線を照射することを特徴とする視覚情報記録媒体が得られる。
【0008】
更に、本発明によれば、上記の視覚情報記録媒体を両支持体間で剥離した時、紫外線が照射された部分は、離型処理された支持体側から紫外線硬化型インクが剥離するが、紫外線を照射されていない部分は紫外線硬化型インクの層内で剥離を起こすため、両側の支持体に分離することを利用した視覚情報の発現方法が得られる。
【0009】
つまり、本発明は、紫外線硬化型インク層を両側から支持体で挟み込むようにし、支持体の少なくとも片側を紫外線が透過する材質としておき、こちら側から紫外線を発現させたい情報の形状(文字・数字・図形 等)で照射する。紫外線硬化型インクと接する支持体の面のどちらか一方を離型処理しておくことにより、情報発現時支持体同士を引き剥がすと、紫外線が照射された部分は、紫外線硬化型インクが全て離型処理されていない側の支持体に転写するが、紫外線が照射されていない部分は紫外線硬化型インクの層内で剥離を起こすため、離型処理がされている側の支持体に、紫外線で照射された情報の形状が発現するという内容である。
【0010】
紫外線硬化型インク層は、全面印刷であることが好ましいが、両側支持体を剥離した時、発現させたい情報の形状が視覚的に十分判別可能であれば、細かい地紋印刷や通常の図柄印刷でもかまわない。また、両支持体を剥離するときに容易なように、支持体のエッジの一部に紫外線硬化インクが印刷されていない部分を設けてもかまわない。但し、地紋印刷や図柄印刷及び一部インクが印刷されていない部分を設ける印刷を行うときは、紫外線硬化インク層が支持体の全面積に対して少なすぎると、自然に支持体同士が剥離してしまったり、小さな力でずれを生じてしまうため、注意を要する。
【0011】
離型処理されている支持体の離型処理の程度は、離型処理されていない側の支持体と使用する紫外線硬化型インクとの組み合わせで適当なものを選ぶ必要がある。離型処理が紫外線硬化型インクに対して強すぎると、インク層内で剥離を起こさず、離型面から剥離を起こしてしまうため注意を要する。
【0012】
紫外線硬化型インク層の厚さは、特に指定はないが、1〜20μm、特に好ましくは2〜10μm程度が望ましい。薄すぎるとインク層内での剥離が起こり難く、また層内で剥離が起こっても発現した情報とのコントラストが取りにくくなる。厚すぎると紫外線で硬化したつもりの部分でも完全には硬化されず、未硬化部分が残存してしまい、記録した情報が良好に発現し難くなる。両側支持体層の厚さは、特に指定はないが、ポリエチレンテレフタレート(以下、PETと記す)を支持体とする場合10〜250μm、特に好ましくは30〜188μm程度が望ましい。厚すぎても薄すぎても両支持体同士を剥離し難くなってくる。
【0013】
即ち、本発明は、シート状の第一の支持体上に紫外線硬化型インクを積層し、少なくとも片面が離型処理されたシート状の第二の支持体を、離型面が紫外線硬化型インクと接するように積層した構成を有し、前記第一の支持体、第二の支持体のうち、少なくとも片側を紫外線を透過する材質とする視覚情報記録媒体である。
【0014】
また、本発明は、前記視覚情報記録媒体において、前記紫外線を透過する支持体を透明PETとする視覚情報記録媒体である。
【0015】
また、本発明は、シート状の第一の支持体上に紫外線硬化型インクを積層し、該紫外線硬化型インクの硬化を行わずに、少なくとも片面が離型処理されたシート状の第二の支持体を、離型面が紫外線硬化型インクと接するように積層し、両側支持体のうち、少なくとも片側が紫外線を透過する材質を使用した視覚情報記録媒体を用い、紫外線を透過する方の支持体側から、前記紫外線硬化型インクの硬化した部分が、視認可能なパターンを形成するように紫外線を照射する視覚情報発現方法において、前記視覚情報記録媒体を両支持体間で剥離した時、紫外線が照射された部分は、離型処理された面から紫外線硬化型インクが剥離し、紫外線が照射されていない部分は紫外線硬化型インクの層内で剥離を起こし、両側の支持体に分離することで視認可能なパターンが形成される視覚情報発現方法である。
【0016】
【発明の実施の形態】
本発明の実施の形態による視覚情報記録媒体及び視覚情報発現方法について、以下に説明する。
【0017】
(実施の形態1)
図1は、本発明の実施の形態1による視覚情報記録媒体の断面図である。図1の視覚情報記録媒体は、白PET3の上に、紫外線硬化型インク層2を形成し、その上に、透明PET1を配置した構造である。また、紫外線硬化型インク層2と透明PET1との間は、離型処理されている。
【0018】
ここで、紫外線は、透明PET1側から照射し、透明PET1と白PET3とを剥離すると、紫外線の照射形状に、離型処理された透明PET1側からインクが剥がれ、離型処理された透明PET1側に記録した情報が発現する。
【0019】
この視覚情報記録媒体は、以下のごとく作製される。先ず、視覚情報記録媒体を作製する。白PET(188μm厚、三菱化学ポリエステル製400J w−14)にオフセット印刷用紫外線硬化型墨インク(T&K TOKA製No2.BF−GK墨)をオフセット印刷により3μm厚に全面印刷後、紫外線硬化を実施せずに透明PET(50μm厚、片面重剥離処理品、三菱化学ポリエステル製ピューレックス#71)の離型処理面側をインクに接するようにラミネートし、得られたシートをJISサイズ(85.6mm×54.0mm)に金型で打ち抜き、視覚情報記録媒体を得た。
【0020】
図4は、本発明の実施の形態による視覚情報発現方法の説明図である。図4に示すように、紫外線を透過しない材質のマスキングシート12から1〜7までの数字(記録情報11)を部分的に除去したシートを用いて前記の視覚情報記録媒体の透明PET1a側からマスキングするように覆った後、紫外線を照射する。
【0021】
このようにすることにより、視覚情報記録媒体は、マスキングされた部分以外は紫外線により硬化を起こし視覚情報が記録される。その後、マスキングシート12を除去し、視覚情報記録媒体を得た。この媒体の紫外線硬化墨インク層は、連続の繋がりを持っており、紫外線照射後も1〜7までの数字を目視で判別することは、非常に困難な状態を作り出すことができた。
【0022】
このようにして得られた視覚情報記録媒体を用い、両側の基材PETを剥離したところ、紫外線硬化が終了している部分は、離型PET側には残存せず、離型PET側に1〜7の数字、記録情報11の抜け部分が現れ、記録情報として発現した。
【0023】
本実施の形態では、紫外線硬化時のマスキングとして紫外線を透過しないマスキングシート12を用いたが、例えば連続で紫外線を透過する形状が変わっていくような金属製のヘッドのようなものを用いてもかまわない。
【0024】
(実施の形態2)
図2は、本発明の実施の形態2による視覚情報記録媒体の断面図である。図2の視覚情報記録媒体は、透明PET6の上に、紫外線硬化型インク層5を形成し、その上に、白PET4を配置した構造である。また、紫外線硬化型インク層5と白PET4との間は、離型処理されている。
【0025】
ここで、紫外線は、透明PET6側から照射し、透明PET6と白PET4とを剥離すると、紫外線の照射形状に、離型処理された白PET4側からインクが剥がれ、離型処理された白PET4側に記録した情報が発現する。
【0026】
(実施の形態3)
図3は、本発明の実施の形態3による視覚情報記録媒体の断面図である。図3の視覚情報記録媒体は、透明PET9の上に、紫外線硬化型インク層8を形成し、その上に、透明PET7を配置した構造である。また、紫外線硬化型インク層8と透明PET7との間は、離型処理されている。
【0027】
ここで、紫外線は、透明PET7側あるいは透明PET9側から照射し、透明PET7側と透明PET9側とを剥離すると、紫外線の照射形状に、離型処理された透明PET7側からインクが剥がれ、離型処理された透明PET7側に記録した情報が発現する。
【0028】
【発明の効果】

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a visual information recording medium and a visual information expressing method in which visual information is hidden when received by a user.
[0002]
[Prior art]
In recent years, visual information recording media have been used in various fields. For example, as one example, a scratch-type visual information recording medium is used. A sheet in which a user can confirm hidden visual information for the first time by shaving off a surface concealed object with a nail or a coin is referred to as a scratch (scratch) sheet. A typical example of a product to which a scratch sheet is applied is a scratch card provided with a scratch portion on a part of a sheet. Scratch cards are widely used as prepaid cards mainly used for international calls, mobile phones and the like.
[0003]
As another example, lottery in lottery, lottery, etc. can be raised. The printed visual information is printed on a printing base material such as paper and folded in two, and the overlapping peripheral parts are glued, etc., so that the printed visual information is processed so that it cannot be known from the external appearance. ing.
[0004]
[Problems to be solved by the invention]
However, in the case of the scratch method, it is not easy to completely hide the visual information of the base with the scratch layer. Therefore, in order to enhance the concealment property, the scratch layer is thickly applied, and sometimes the multilayer is applied. It is necessary to print the image to make the visual information of the background difficult to see, leading to an increase in cost. Further, regarding the lottery, the conventional lottery in which the visual information is simply printed has a problem that the printed visual information is modified and the lottery is easily forged or falsified.
[0005]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a visual information recording medium which eliminates the above-mentioned disadvantages, makes it extremely difficult to recognize visual information in a state before use, and can further prevent forgery and falsification, and a visual information expressing method thereof And
[0006]
[Means for Solving the Problems]
According to the present invention, an ultraviolet-curable ink is laminated on a support, and without curing, an opposing support having at least one surface subjected to a release treatment is laminated such that the release surface is in contact with the ultraviolet-curable ink. Thus, a visual information recording medium having a structure in which at least one of the two-sided supports uses a material that transmits ultraviolet light can be obtained.
[0007]
Further, according to the present invention, there is provided a visual information recording medium characterized by partially irradiating the medium with ultraviolet light in a shape desired to be used as visual information from the support side that transmits ultraviolet light.
[0008]
Further, according to the present invention, when the visual information recording medium is peeled between the two supports, the portion irradiated with ultraviolet rays, the ultraviolet curable ink is peeled from the release-treated support side, Since the portion not irradiated with the ink is peeled off in the layer of the ultraviolet-curable ink, a method for expressing visual information utilizing separation into the supports on both sides can be obtained.
[0009]
That is, according to the present invention, the ultraviolet-curable ink layer is sandwiched between the supports from both sides, at least one side of the support is made of a material through which ultraviolet light is transmitted, and the shape of information (characters and numerals) in which ultraviolet light is to be expressed from this side is set.・ Irradiate with figures. By releasing one of the surfaces of the support that is in contact with the ultraviolet-curable ink, the support is peeled off at the time of information expression. The image is transferred to the support that has not been subjected to the mold treatment.However, since the portion that has not been irradiated with ultraviolet rays causes peeling in the layer of the ultraviolet curable ink, the support that has been subjected to the mold release treatment is exposed to ultraviolet light. The content is that the shape of the irradiated information appears.
[0010]
The UV-curable ink layer is preferably printed on the entire surface, but when the two-sided support is peeled off, if the shape of the information to be expressed can be visually discriminated sufficiently, it can be used for fine copy-forgery-inhibited pattern printing or ordinary pattern printing. I don't care. Further, a part where the ultraviolet curable ink is not printed may be provided on a part of the edge of the support so that the support can be easily separated. However, when performing tint block printing, pattern printing, and printing in which a part of the ink is not printed, if the ultraviolet curable ink layer is too small relative to the entire area of the support, the supports will naturally peel off from each other. Care must be taken because they can be misaligned or displaced by small forces.
[0011]
It is necessary to select an appropriate degree of the release treatment of the support that has been subjected to the release treatment, in accordance with the combination of the support that has not been subjected to the release treatment and the ultraviolet curable ink to be used. If the release treatment is too strong with respect to the ultraviolet curable ink, the release will not occur in the ink layer but will occur from the release surface, so care must be taken.
[0012]
The thickness of the ultraviolet-curable ink layer is not particularly specified, but is preferably 1 to 20 μm, particularly preferably about 2 to 10 μm. If the thickness is too thin, peeling in the ink layer hardly occurs, and even if peeling occurs in the layer, it is difficult to obtain a contrast with the developed information. If it is too thick, even the portion that is intended to be cured by ultraviolet light will not be completely cured, and the uncured portion will remain, making it difficult for the recorded information to be expressed well. Although the thickness of the both-side support layer is not particularly specified, when polyethylene terephthalate (hereinafter referred to as PET) is used as the support, the thickness is preferably about 10 to 250 μm, particularly preferably about 30 to 188 μm. If the support is too thick or too thin, it becomes difficult to separate the two supports.
[0013]
That is, the present invention provides a sheet-shaped second support having a release surface laminated on at least one surface of a sheet-shaped first support, and a release surface of the ultraviolet-curable ink. A visual information recording medium having a structure in which at least one of the first support and the second support is made of a material that transmits ultraviolet light.
[0014]
Further, the present invention is the visual information recording medium, wherein the support transmitting the ultraviolet rays is transparent PET.
[0015]
The present invention also provides a sheet-like second substrate having at least one surface subjected to a release treatment by laminating an ultraviolet-curable ink on a sheet-like first support, without curing the ultraviolet-curable ink. The support is laminated such that the release surface is in contact with the ultraviolet-curable ink, and of the two-sided support, at least one side uses a visual information recording medium using a material that transmits ultraviolet light, and the support of the one that transmits ultraviolet light is used. From the body side, in the visual information expression method in which the cured portion of the ultraviolet curable ink is irradiated with ultraviolet light so as to form a visible pattern, when the visual information recording medium is peeled between both supports, the ultraviolet light The UV-curable ink is peeled off from the release-treated surface of the irradiated part, and the UV-irradiated part is peeled off in the UV-curable ink layer and separated on the support on both sides. A visual information expressing how visible pattern is formed.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
A visual information recording medium and a visual information expression method according to an embodiment of the present invention will be described below.

The visual information recording medium of FIG. 1 has a structure in which an ultraviolet curable ink layer 2 is formed on a white PET 3 and a transparent PET 1 is disposed thereon. A release treatment is performed between the ultraviolet curable ink layer 2 and the transparent PET 1.
[0018]
Here, when ultraviolet rays are irradiated from the transparent PET1 side and the transparent PET1 and the white PET3 are peeled off, the ink is peeled from the transparent PET1 side subjected to the release treatment into the ultraviolet irradiation shape, and the transparent PET1 side subjected to the release treatment is applied. The information recorded in appears.
[0019]
This visual information recording medium is manufactured as follows. First, a visual information recording medium is manufactured. Offset UV-curable black ink (T & K TOKA No. 2. BF-GK black) is entirely printed on white PET (188 µm thick, 400J w-14 made by Mitsubishi Chemical Polyester) to a thickness of 3 µm by offset printing, and then UV cured. Without releasing, the release-treated side of transparent PET (50 μm thick, single-sided heavy release treated product, Purex # 71 made by Mitsubishi Chemical Polyester) was laminated so as to be in contact with the ink, and the obtained sheet was JIS size (85.6 mm). × 54.0 mm) to obtain a visual information recording medium.
[0020]
FIG. 4 is an explanatory diagram of a visual information expressing method according to the embodiment of the present invention. As shown in FIG. 4, masking is performed from the transparent PET 1a side of the visual information recording medium using a masking sheet 12 made of a material that does not transmit ultraviolet rays and a sheet from which numerals (recording information 11) from 1 to 7 are partially removed. After covering, the substrate is irradiated with ultraviolet rays.
[0021]
By doing so, the visual information recording medium is cured by ultraviolet rays except for the masked portion, and the visual information is recorded. Thereafter, the masking sheet 12 was removed to obtain a visual information recording medium. The ultraviolet-cured black ink layer of this medium has a continuous connection, and it is very difficult to visually determine the numbers from 1 to 7 even after irradiation with ultraviolet rays.
[0022]
Using the visual information recording medium obtained in this way, when the base PET on both sides was peeled off, the part where the ultraviolet curing was completed did not remain on the release PET side, and 1 part was placed on the release PET side. Numerical values up to 7 and missing portions of the recorded information 11 appeared, and appeared as recorded information.
[0023]
In the present embodiment, the masking sheet 12 that does not transmit ultraviolet light is used as masking at the time of curing the ultraviolet light. However, for example, a metal head that continuously changes the shape that transmits ultraviolet light may be used. I don't care.
