Description

本考案は、スキミング防止カードに関する。   The present invention relates to a skimming prevention card.

従来、非接触ICカードをスキミングされることを防止するために、電磁波を遮蔽するためのアルミニウム箔を有するスキミング防止カードが用いられている(例えば、特許文献1参照)。   Conventionally, in order to prevent a non-contact IC card from being skimmed, an anti-skimming card having an aluminum foil for shielding electromagnetic waves has been used (for example, see Patent Document 1).

しかし、スキミング防止カードは、印刷が施される程度の単純な構成であり、面白みに欠けていた。
特開2006−53761号公報
However, the skimming prevention card has a simple configuration to the extent that printing is performed and lacks interest.
JP 2006-53761 A

解決しようとする課題は、単にスキミング防止効果をもつのみであって、面白みに欠けている点である。   The problem to be solved is that it has only a skimming prevention effect and lacks interest.

そこで、本考案に係るスキミング防止カードは、板片状のレンチキュラーレンズと、アルミニウム又は銅から成る金属箔層と、プラスチックから成る補強層と、を順次積層したスキミング防止カードであって、上記レンチキュラーレンズと上記金属箔層とを非加熱非加圧接着剤にて接着したものである。   Therefore, the skimming prevention card according to the present invention is a skimming prevention card in which a plate-like lenticular lens, a metal foil layer made of aluminum or copper, and a reinforcing layer made of plastic are sequentially laminated, and the lenticular lens described above. And the metal foil layer are bonded with a non-heated and non-pressurized adhesive.

また、上記非加熱非加圧接着剤がアクリル・酢ビ共重合体から成るものである。
また、上記レンチキュラーレンズの厚さ寸法T1 を 200μm以上 500μm以下に設定し、かつ、上記金属箔層の厚さ寸法T2 を15μm以上80μm以下に設定し、さらに、上記補強層がOPPから成ると共にその厚さ寸法T3 を20μm以上80μm以下に設定したものである。
The non-heated non-pressurized adhesive is made of an acrylic / vinyl acetate copolymer.
Further, the thickness dimension T 1 of the lenticular lens is set to 200 μm or more and 500 μm or less, the thickness dimension T 2 of the metal foil layer is set to 15 μm or more and 80 μm or less, and the reinforcing layer is made of OPP. In addition, the thickness dimension T 3 is set to 20 μm or more and 80 μm or less.

本考案のスキミング防止カードによれば、スキミング防止効果(電磁波遮断効果)を得られるとともに、変化に富み、面白みがある。そして、広告・宣伝や、名刺として用いるにも好適である。   According to the skimming prevention card of the present invention, a skimming prevention effect (electromagnetic wave shielding effect) can be obtained, and it is rich in change and interesting. It is also suitable for use as an advertisement / promotion or business card.

図1〜図3は、本考案の実施の一形態を示す。このスキミング防止カードを図3のA方向から見ると、図1に示すように図柄P(目を閉じた女性と月)が見える。スキミング防止カードを図3のB方向から見ると、図2に示すように図柄Q(笑顔の女性と太陽)が見える。すなわち、見る方向(A方向又はB方向)によって、異なる図柄(図柄P又は図柄Q)が見える。   1 to 3 show an embodiment of the present invention. When the skimming prevention card is viewed from the direction A in FIG. 3, a pattern P (a woman with the eyes closed and the moon) can be seen as shown in FIG. When the skimming prevention card is viewed from the direction B in FIG. 3, a symbol Q (smiling woman and sun) can be seen as shown in FIG. That is, a different symbol (symbol P or symbol Q) can be seen depending on the viewing direction (direction A or direction B).

具体的には、レンチキュラーレンズ(表面部断面が多数のかまぼこを並べた形状を有する板片状のレンズ)1と、アルミニウム又は銅から成る金属箔層2と、プラスチック(例えばOPP;オリエントポリプロピレン)から成る補強層3(例えば補強シート材)と、が順次積層されている。   Specifically, from a lenticular lens (a plate-like lens having a shape in which a cross section of a surface has a large number of cross-sections) 1, a metal foil layer 2 made of aluminum or copper, and plastic (for example, OPP; orient polypropylene) A reinforcing layer 3 (for example, a reinforcing sheet material) is sequentially laminated.

板片状の(略長方形の)レンチキュラーレンズ1と金属箔層2とが非加熱非加圧接着剤4にて接着されている。「非加熱非加圧接着剤」とは、非加熱かつ非加圧の状態で接着可能な接着剤のことをいう。例えば、非加熱非加圧接着剤4がアクリル・酢ビ共重合体、又は、アクリル酸エステル共重合体から成る。   A plate-like (substantially rectangular) lenticular lens 1 and a metal foil layer 2 are bonded with a non-heated non-pressure adhesive 4. The “non-heated non-pressurized adhesive” refers to an adhesive that can be bonded in a non-heated and non-pressurized state. For example, the non-heated non-pressure adhesive 4 is made of an acrylic / vinyl acetate copolymer or an acrylic ester copolymer.

金属箔層2と補強層3とが接着剤5にて接着されている。接着剤5は、非加熱非加圧接着剤であっても良いし、非加熱非加圧接着剤でなくても良い。例えば、接着剤5がアクリル酸エステル共重合体から成る。   The metal foil layer 2 and the reinforcing layer 3 are bonded with an adhesive 5. The adhesive 5 may be a non-heated non-pressure adhesive or may not be a non-heated non-pressure adhesive. For example, the adhesive 5 is made of an acrylate ester copolymer.

レンチキュラーレンズ1の厚さ寸法T1 が 200μm以上 500μm以下に設定されている。厚さ寸法T1 が 200μm未満の場合、製造するのが困難である。 500μmを超える厚さ寸法T1 は、不必要である。 Thickness T 1 of the lenticular lens 1 is set to 200μm or more 500μm or less. If the thickness dimension T 1 is less than 200 μm, it is difficult to manufacture. A thickness dimension T 1 exceeding 500 μm is unnecessary.

金属箔層2の厚さ寸法T2 が15μm以上80μm以下に設定されている。厚さ寸法T2 が15μm未満の場合、適切なスキミング防止効果が得られない。80μmを超える厚さ寸法T2 は、不必要である。 Thickness T 2 of the metal foil layer 2 is set to 15μm or 80μm or less. When the thickness dimension T 2 is less than 15 μm, an appropriate skimming prevention effect cannot be obtained. A thickness dimension T 2 exceeding 80 μm is unnecessary.

補強層3の厚さ寸法T3 が20μm以上80μm以下に設定されている。厚さ寸法T3 が20μm未満の場合、強度不足になる。80μmを超える厚さ寸法T3 は、不必要である。 Thickness T 3 of the reinforcing layer 3 is set to 20μm or 80μm or less. When the thickness dimension T 3 is less than 20 μm, the strength is insufficient. A thickness dimension T 3 exceeding 80 μm is unnecessary.

次に、上述のスキミング防止カードの製法について説明する。まず、金属箔層2と補強層3を接着剤5にて接着して積層する。その後、レンチキュラーレンズ1と、(補強層5と積層一体化された)金属箔層2とを、非加熱非加圧接着剤4にて、非加熱非加圧状態で接着して積層する。なお、レンチキュラーレンズ1には、あらかじめ(分断状の)図柄P及び図柄Qが、見る方向によって異なるように印刷されている。   Next, the manufacturing method of the above skimming prevention card will be described. First, the metal foil layer 2 and the reinforcing layer 3 are bonded and laminated with an adhesive 5. Thereafter, the lenticular lens 1 and the metal foil layer 2 (integrated and laminated with the reinforcing layer 5) are bonded and laminated with a non-heated and non-pressurized adhesive 4 in a non-heated and non-pressurized state. Note that the lenticular lens 1 is preliminarily printed with a (divided) pattern P and a pattern Q that differ depending on the viewing direction.

本考案は、設計変更可能であって、例えば、補強層3が通常のポリプロピレン等のプラスチックから成るも良い。また、非加熱非加圧接着剤4及び接着剤5は、上述のものに限定されない。また、チェインジングする図柄は、3種類以上であるも好ましい。また、(レンチキュラーレンズ1に直接図柄を印刷するのではなく、)レンチキュラーレンズ1と金属箔層2の間に(分断状の)図柄P及び図柄Qを印刷した紙を積層させるも良い。また、補強層3は(接着によらず)金属箔層2に溶融プラスチックをラミネートしたものであっても良い。   In the present invention, the design can be changed. For example, the reinforcing layer 3 may be made of an ordinary plastic such as polypropylene. Moreover, the non-heating non-pressure adhesive 4 and the adhesive 5 are not limited to the above-mentioned thing. Moreover, it is also preferable that there are three or more types of symbols to be chained. Further, a paper on which the design P and the design Q (partitioned) are printed may be laminated between the lenticular lens 1 and the metal foil layer 2 (rather than printing the design directly on the lenticular lens 1). Further, the reinforcing layer 3 (regardless of adhesion) may be obtained by laminating a molten plastic on the metal foil layer 2.

以上のように、本考案は、板片状のレンチキュラーレンズ1と、アルミニウム又は銅から成る金属箔層2と、プラスチックから成る補強層3と、を順次積層したスキミング防止カードであって、レンチキュラーレンズ1と金属箔層2とを非加熱非加圧接着剤4にて接着したので、スキミング防止効果を得られる(すなわち電磁波を遮断することによりカード情報を保護することができる)とともに、変化に富み、面白みがある。そして、広告・宣伝や、名刺として用いるにも好適である。加熱・加圧により接着せんとすれば、微細なかまぼこ型凸部が破壊・損傷を受けるので、レンチキュラーレンズ1の接着(積層)はできないところ、本考案は非加熱非加圧接着剤4を用いるものなので、レンチキュラーレンズ1を積層させたものを製造することができる。   As described above, the present invention is a skimming prevention card in which a plate-like lenticular lens 1, a metal foil layer 2 made of aluminum or copper, and a reinforcing layer 3 made of plastic are sequentially laminated, and the lenticular lens 1 and the metal foil layer 2 are bonded to each other by the non-heated non-pressurizing adhesive 4, so that a skimming prevention effect can be obtained (that is, card information can be protected by blocking electromagnetic waves) and a variety of changes can be achieved. It ’s interesting. It is also suitable for use as an advertisement / promotion or business card. If bonding is performed by heating and pressing, the fine kamaboko-shaped convex portion will be destroyed or damaged, so that the lenticular lens 1 cannot be bonded (laminated), but the present invention uses an unheated non-pressing adhesive 4 Since it is a thing, what laminated | stacked the lenticular lens 1 can be manufactured.

また、非加熱非加圧接着剤4がアクリル・酢ビ共重合体から成るので、確実にレンチキュラーレンズ1と金属箔層2を接着することができる。   Further, since the non-heated and non-pressurized adhesive 4 is made of an acrylic / vinyl acetate copolymer, the lenticular lens 1 and the metal foil layer 2 can be securely bonded.

また、レンチキュラーレンズ1の厚さ寸法T1 を 200μm以上 500μm以下に設定し、かつ、金属箔層2の厚さ寸法T2 を15μm以上80μm以下に設定し、さらに、補強層3がOPPから成ると共にその厚さ寸法T3 を20μm以上80μm以下に設定したので、全体を合理的な厚さ寸法とすることができる。すなわち、スキミング防止効果を適切に得ることができ、かつ、全体として無駄がない厚さ寸法とすることができる。金属箔層2を適切に保護することができる。さらに、補強層3がOPPから成るので、強度的に優れる。 Also, setting the thickness T 1 of the lenticular lens 1 to 200μm or more 500μm or less, and the thickness T 2 of the metal foil layer 2 is set to 15μm or 80μm or less, further, the reinforcing layer 3 is made of OPP At the same time, since the thickness dimension T 3 is set to 20 μm or more and 80 μm or less, the entire thickness can be set to a reasonable thickness dimension. That is, it is possible to appropriately obtain a skimming prevention effect and to have a thickness dimension that is not wasted as a whole. The metal foil layer 2 can be appropriately protected. Furthermore, since the reinforcing layer 3 is made of OPP, it is excellent in strength.
