Abstract
Description
本発明は、情報隠蔽用紙に関し、更に詳しくは、弱圧で情報の隠蔽が可能な情報隠蔽用紙に関する。 The present invention relates to an information concealment sheet, and more particularly to an information concealment sheet capable of concealing information with low pressure.
近年、銀行、クレジット会社、官公庁等より個人宛に各個人の預金状況、残高情報、年金情報等を通知する手段として情報隠蔽用紙が使用されている。かかる情報隠蔽用紙に使用される用紙は、その情報記載面に、感圧接着剤が塗工されており、低い圧力では全く接着しないが、所定圧力以上で圧着すると接着するよう構成されている（特許文献１，２）。
In recent years, information concealment sheets have been used as means for notifying individual individuals of deposit status, balance information, pension information, and the like from banks, credit companies, government offices, and the like. The paper used for such information concealment paper is coated with a pressure-sensitive adhesive on its information description surface, so that it does not adhere at all at low pressure, but it adheres when it is crimped above a predetermined pressure (
しかし、従来の感圧接着剤は、接着に比較的高い圧力を要するため、接着にはドライシーラー等の圧着装置が必要であり、用途が限られていた。 However, since the conventional pressure-sensitive adhesive requires a relatively high pressure for bonding, a bonding device such as a dry sealer is required for bonding, and its application is limited.
本発明は、大規模な圧着装置を必要とせず、手でこする程度の弱圧でも情報の隠蔽が可能な情報隠蔽用紙を提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide an information concealment sheet that does not require a large-scale crimping apparatus and can conceal information even with a low pressure that can be rubbed by hand.
すなわち、本発明の情報隠蔽用紙は、情報記入領域を有する情報記入片と、前記情報記入片の一辺に連接され、少なくとも前記情報記入領域を隠蔽する隠蔽片と、前記情報記入片と前記隠蔽片の少なくとも一方に形成された接着層とを有する情報隠蔽用紙であって、前記接着層が、アクリル変性天然ゴムラテックスと、過酸化物前加硫ラテックスと、合成ゴムラテックスとを含有する感圧接着剤組成物を塗布形成してなる層であることを特徴とする。 That is, the information concealment sheet of the present invention includes an information entry piece having an information entry area, a concealment piece connected to one side of the information entry piece and concealing at least the information entry area, the information entry piece, and the concealment piece An information hiding paper having an adhesive layer formed on at least one of the above, wherein the adhesive layer contains an acrylic-modified natural rubber latex, a pre-peroxide vulcanized latex, and a synthetic rubber latex. It is a layer formed by coating and forming an agent composition.
本発明の情報隠蔽用紙の接着層は、弱圧での接着が可能であり、例えば、接着層同士を対向させて、硬貨、ペン先等を用いて比較的強めに数回こする程度で接着することができる。そのため、接着にドライシーラー等の圧着装置を必要としない。 The adhesive layer of the information hiding paper of the present invention can be bonded with low pressure. For example, the adhesive layer can be bonded to the adhesive layer with the adhesive layers facing each other and rubbed relatively hard several times using a coin, a nib or the like. can do. Therefore, a pressure bonding device such as a dry sealer is not required for bonding.
また、本発明の情報隠蔽用紙の接着層は、通常状態では接着しないため、接着層を剥離紙等で保護する必要がなく、コスドダウンを図れる。また、接着層は透明であり、基材（情報記入片、隠蔽片）に印刷された文字等を視認できるし、接着層自体が印刷適性を有するため、接着層表面に印刷することも可能である。更に、レーザープリンター、インクジェットプリンター等により印字が可能である。 Further, since the adhesive layer of the information hiding paper of the present invention does not adhere in a normal state, it is not necessary to protect the adhesive layer with a release paper or the like, and cost reduction can be achieved. Moreover, since the adhesive layer is transparent, characters printed on the base material (information entry piece, concealment piece) can be visually recognized, and the adhesive layer itself has printability, so it is possible to print on the surface of the adhesive layer. is there. Furthermore, printing is possible with a laser printer, an ink jet printer, or the like.
また、本発明の情報隠蔽用紙の接着層は、一旦接着した後に剥離することが可能であり、その後は、再度加圧しても再び接着することはない。しかも、剥離時には、情報記入領域に記入された情報の確認には支障がないが、剥離した痕跡が残る程度に基材が破れる。 In addition, the adhesive layer of the information hiding paper of the present invention can be peeled off after being bonded once, and thereafter it will not be bonded again even if it is pressed again. Moreover, at the time of peeling, there is no problem in confirming the information entered in the information entry area, but the base material is broken to the extent that the peeled trace remains.
更に、本発明の情報隠蔽用紙の接着層は、接着力を調整することにより、接着後に基材を破ることなく剥離する擬似接着タイプの接着層とすることが可能である。 Furthermore, the adhesive layer of the information hiding paper of the present invention can be a pseudo-adhesive type adhesive layer that peels without tearing the substrate after bonding by adjusting the adhesive force.
以下、本発明の情報隠蔽用紙について、図面を用いて説明する。 Hereinafter, the information hiding paper of the present invention will be described with reference to the drawings.
図１は、本発明を生命保険の告知書に適用した例を示す図であり、図１（ａ）は平面図、図１（ｂ）は隠蔽片で情報記入領域を隠蔽している状態を示す斜視図である。 FIG. 1 is a diagram showing an example in which the present invention is applied to a life insurance notice. FIG. 1 (a) is a plan view, and FIG. 1 (b) is a state where an information entry area is concealed by a concealment piece. It is a perspective view shown.
図１において、１は情報記入領域２を有する情報記入片、３は情報記入片１の一辺に連接され、少なくとも情報記入領域２を隠蔽する隠蔽片、４は隠蔽片３の、情報記入領域２と対向する領域（隠蔽領域）であり、５は接着層である。
In FIG. 1, 1 is an information entry piece having an
図１に示す告知書は、図１（ａ）に示す状態で、保険加入者に配布される。接着層５は、情報記入領域２と隠蔽領域４との外周に沿って、情報記入片１と隠蔽片３に跨って形成されている。そのため、隠蔽片３を折り曲げると、情報記入片１側の接着層５と、隠蔽片３側の接着層５が対向する。接着層５は通常状態では接着しないため、接着層５を剥離紙等で保護する必要はない。尚、接着層５の形成位置は、図１に示す位置に限定されないが、情報記入片１の情報記入領域２以外の領域及び／または隠蔽片３の隠蔽領域４以外の領域に形成することが好ましく、情報記入片１側の接着層５と隠蔽片３側の接着層５とが対向する位置に形成することが好ましい。
The notice shown in FIG. 1 is distributed to insurance subscribers in the state shown in FIG. The
保険加入者は、情報記入片１の情報記入領域２に必要事項を記入し、図１（ｂ）に示す様に隠蔽片３を折り曲げて情報記入領域２を隠蔽する。その後、隠蔽片３の接着層５に対応する位置を中心に、硬貨、ペン先等を用いて比較的強めに数回こする程度の弱圧を加え、隠蔽片３を情報記入片１に接着する。告知書は、この状態で保険会社に提出される。
The insurance subscriber enters necessary information in the
隠蔽片３は、剥離することが可能であり、一旦剥離すると再度加圧しても再び接着することはない。しかも、接着層５を形成する感圧接着剤組成物の組成を調整することにより、隠蔽片３を剥離する際に、情報記入領域２に記入された情報の確認には支障がないが、剥離した痕跡が残る程度に情報記入片１または隠蔽片３が破れる接着層、情報記入片１及び隠蔽片３が破れない接着層のいずれをも形成することが可能である。
The
接着層５は、アクリル変性天然ゴムラテックスと、過酸化物前加硫ラテックスと、合成ゴムラテックスとを含有する感圧接着剤組成物を塗布形成してなる層である。
The
アクリル変性天然ゴムラテックスは、天然ゴムラテックスをアクリル系単量体でグラフとしたラテックスである。アクリル系単量体としては、例えばアクリル酸メチル、アクリル酸ｎ−ブチル、アクリル酸ヘキシル、メタクリル酸メチル等が挙げられ、これらのうちでもメタクリル酸メチルが好ましい。また、グラフト化の度合いは、天然ゴム比５〜５０重量％であることが好ましい。 The acrylic modified natural rubber latex is a latex obtained by graphing natural rubber latex with acrylic monomers. Examples of the acrylic monomer include methyl acrylate, n-butyl acrylate, hexyl acrylate, and methyl methacrylate. Among these, methyl methacrylate is preferable. The degree of grafting is preferably 5 to 50% by weight relative to the natural rubber.
過酸化物前加硫ラテックスは、天然ゴムラテックスを過酸化物で前加硫したラテックスである。過酸化物としては、例えばベンゾイルパーオキシド、ジｔ−ブチルパーオキシジイソプロピルベンゼン、ｔ−ブチルハイドロパーオキシド等が挙げられ、これらのうちでもｔ−ブチルハイドロオキシドが、反応時のラテックス分散性、安定性に優れていることが知られている。 Peroxide pre-cured latex is a latex obtained by pre-curing natural rubber latex with peroxide. Examples of peroxides include benzoyl peroxide, di-t-butylperoxydiisopropylbenzene, and t-butyl hydroperoxide. Among these, t-butyl hydroxide is latex dispersibility and stability during the reaction. It is known to be excellent in properties.
合成ゴムラテックスとしては、例えば、スチレン−ブタジエンゴムラテックス、アクリロニトリル−ブタジエンゴムラテックス、ブタジエンゴムラテックス、クロロプレンゴムラテックス、ウレタンゴムラテックス等々が挙げられる。 Examples of the synthetic rubber latex include styrene-butadiene rubber latex, acrylonitrile-butadiene rubber latex, butadiene rubber latex, chloroprene rubber latex, urethane rubber latex, and the like.
アクリル変性天然ゴムラテックス（樹脂固形分）と過酸化物前加硫ラテックス（樹脂固形分）の合計量と、合成ゴムラテックス（樹脂固形分）との配合比率（アクリル変性天然ゴムラテックス（樹脂固形分）と過酸化物前加硫ラテックス（樹脂固形分）の合計量：合成ゴムラテックス（樹脂固形分））は、重量比で６０：４０〜９０：１０であることが好ましく、より好ましくは７０：３０〜８５：１５である。アクリル変性天然ゴムラテックスと過酸化物前加硫ラテックスの合計量がこの範囲より多すぎると（合成ゴムラテックスがこの範囲より少なすぎると）、基材への密着性、剥離時の凝集力が不足する傾向があり、アクリル変性天然ゴムラテックスと過酸化物前加硫ラテックスの合計量がこの範囲より少なすぎると（合成ゴムラテックスがこの範囲より多すぎると）、接着力が低下する傾向がある。 The blending ratio of acrylic modified natural rubber latex (resin solids) and pre-peroxide vulcanized latex (resin solids) to synthetic rubber latex (resin solids) (acrylic modified natural rubber latex (resin solids) ) And pre-peroxide vulcanized latex (resin solid content): the synthetic rubber latex (resin solid content)) is preferably 60:40 to 90:10 by weight, more preferably 70: 30-85: 15. If the total amount of acrylic-modified natural rubber latex and pre-peroxide vulcanized latex is too much above this range (if the synthetic rubber latex is too much below this range), adhesion to the substrate and cohesive force at the time of peeling will be insufficient. If the total amount of the acrylic modified natural rubber latex and the pre-peroxide vulcanized latex is too smaller than this range (if the synthetic rubber latex is more than this range), the adhesive force tends to decrease.
また、アクリル変性天然ゴムラテックス（樹脂固形分）と過酸化物前加硫ラテックス（樹脂固形分）との配合比率（アクリル変性天然ゴムラテックス：過酸化物前加硫ラテックス）は、重量比で１０：９０〜９０：１０であることが好ましく、より好ましくは２０：８０〜３０：７０であるが、擬似接着タイプの組成物とする場合は８０：２０〜７０：３０であることがより好ましい。アクリル変性天然ゴムラテックスがこの範囲より多すぎると（過酸化物前加硫ラテックスがこの範囲より少なすぎると）、接着に要する圧力が高くなる傾向があり、アクリル変性天然ゴムラテックスがこの範囲より少なすぎると（過酸化物前加硫ラテックスがこの範囲より多すぎると）、剥離が困難になる傾向があり、無理に剥離すると基材の破損を生じる可能性がある。 The blending ratio (acrylic modified natural rubber latex: peroxide precured latex) of the acrylic modified natural rubber latex (resin solid content) and the pre-peroxide vulcanized latex (resin solid content) is 10 by weight. Is preferably 90:90:10, more preferably 20: 80-30: 70, but more preferably 80: 20-70: 30 in the case of a pseudo-adhesive type composition. If the amount of acrylic modified natural rubber latex is too much above this range (if the amount of pre-peroxide vulcanized latex is too small than this range), the pressure required for adhesion tends to increase, and the amount of acrylic modified natural rubber latex is below this range. If it is too much (when the amount of the pre-peroxide vulcanized latex is more than this range), the peeling tends to be difficult, and if it is peeled forcibly, the substrate may be damaged.
感圧接着剤組成物中のアクリル変性天然ゴムラテックス（樹脂固形分）と過酸化物前加硫ラテックス（樹脂固形分）と合成ゴムラテックス（樹脂固形分）との合計含有量は、好ましくは５０〜７０重量％、より好ましくは６０〜７０重量％である。合計含有量が５０重量％未満では接着力が低下する傾向があり、７０重量％を超えると剥離が困難になる傾向があり、無理に剥離すると基材の破損を生じる可能性がある。 The total content of acrylic-modified natural rubber latex (resin solid content), peroxide pre-vulcanized latex (resin solid content) and synthetic rubber latex (resin solid content) in the pressure-sensitive adhesive composition is preferably 50. It is -70 weight%, More preferably, it is 60-70 weight%. If the total content is less than 50% by weight, the adhesive strength tends to decrease, and if it exceeds 70% by weight, peeling tends to be difficult, and if it is peeled forcibly, the substrate may be damaged.
感圧接着剤組成物は、保存時の接着層同士の接着を避ける為にアンチブロッキング剤を含有することが好ましい。 The pressure-sensitive adhesive composition preferably contains an antiblocking agent in order to avoid adhesion between the adhesive layers during storage.
アンチブロッキング剤の含有量は、アクリル変性天然ゴムラテックス（樹脂固形分）と過酸化物前加硫ラテックス（樹脂固形分）と合成ゴムラテックス（樹脂固形分）との合計量１００重量部に対し１０〜５０重量部であることが好ましく、１０〜３０重量部であることがより好ましい。アンチブロッキング剤の含有量が１０重量部未満では保存時に接着層同士が接着する可能性があり、５０重量部を超えると接着力が低下する傾向がある。 The content of the anti-blocking agent is 10 with respect to 100 parts by weight of the total amount of acrylic modified natural rubber latex (resin solid content), pre-peroxide vulcanized latex (resin solid content), and synthetic rubber latex (resin solid content). It is preferably ˜50 parts by weight, and more preferably 10 to 30 parts by weight. If the content of the anti-blocking agent is less than 10 parts by weight, the adhesive layers may adhere to each other during storage, and if it exceeds 50 parts by weight, the adhesive strength tends to decrease.
アンチブロッキング剤としては、例えば、重炭酸カルシウム、軽炭酸カルシウム、タルク、ステアリン酸金属石けん、でん粉、シリカ等が挙げられる。これらのうちでも、接着層形成後のレーザープリンターによる印刷等に対する耐熱性を向上せしめる為にシリカを含有させることが好ましい。また、擬似接着タイプの組成物とする場合には、でん粉を含有させることが好ましく、その含有量は、好ましくはアンチブロッキング剤中４０〜８０重量％、より好ましくは５０〜７０重量％である。 Examples of the anti-blocking agent include calcium bicarbonate, light calcium carbonate, talc, metal stearate soap, starch, silica and the like. Among these, it is preferable to contain silica in order to improve heat resistance against printing by a laser printer after forming the adhesive layer. Moreover, when setting it as a pseudo-adhesion type composition, it is preferable to contain a starch, and the content is preferably 40 to 80% by weight, more preferably 50 to 70% by weight in the antiblocking agent.
感圧接着剤組成物には、塗工適性を維持・向上せしめる為に、界面活性剤、消泡剤、増粘剤等の添加物を添加してもよい。界面活性剤としては、ノニオン界面活性剤とアニオン界面活性剤を併用することが好ましく、ノニオン界面活性剤としては、ポリオキシエチレンラウリルエーテル、ポリオキシエチレンスチレン化フェニルエーテル、ポリオキシエチレンアルキルエーテル等で、ＨＬＢが１３．０〜１９．０のもの、アニオン界面活性剤としては、アルキルベンゼンスルホン酸ナトリウム、高級アルコール硫酸エステルナトリウム、硫酸エステル系等を用いることができる。消泡剤としては非シリコン系消泡剤が接着力に影響をされずに好ましく、０．１〜０．５重量％程度添加することが好ましい。増粘剤はコーターの塗工適性上のため使用され、アクリル系、ポリアクリル酸、ＰＶＡ、ＣＭＣ等、セルローズ系増粘剤を用いることができるが、アクリル系増粘剤が粘度の経時変化も少なく好ましい。 In order to maintain and improve the coating suitability, additives such as a surfactant, an antifoaming agent, and a thickener may be added to the pressure-sensitive adhesive composition. As the surfactant, it is preferable to use a nonionic surfactant and an anionic surfactant in combination. Examples of the nonionic surfactant include polyoxyethylene lauryl ether, polyoxyethylene styrenated phenyl ether, and polyoxyethylene alkyl ether. As the anionic surfactant having an HLB of 13.0 to 19.0, sodium alkylbenzene sulfonate, sodium higher alcohol sulfate, sulfate ester or the like can be used. As the antifoaming agent, a non-silicon antifoaming agent is preferable without affecting the adhesive force, and it is preferable to add about 0.1 to 0.5% by weight. Thickeners are used for coater coating suitability, and acrylic, polyacrylic acid, PVA, CMC, etc., cellulose thickeners can be used, but acrylic thickeners also change in viscosity over time. Less preferred.
感圧接着剤組成物は、例えば、アクリル変性天然ゴムラテックスと過酸化物前加硫ラテックスとを配合し、要すれば界面活性剤を添加した後に、合成ゴムラテックスを配合し、要すればアンチブロッキング剤を添加し、更に必要に応じて消泡剤、増粘剤等の添加物を添加して混合することにより製造することができる。アンチブロッキング剤は、分散性をよくするために界面活性剤等の分散媒中に分散させて添加することが好ましい。 The pressure-sensitive adhesive composition is prepared by, for example, blending an acrylic-modified natural rubber latex and a pre-peroxide vulcanized latex, adding a surfactant if necessary, and then blending a synthetic rubber latex, It can be produced by adding a blocking agent and, if necessary, adding additives such as an antifoaming agent and a thickener and mixing them. The antiblocking agent is preferably added after being dispersed in a dispersion medium such as a surfactant in order to improve dispersibility.
接着層５は、感圧接着剤組成物を、グラビアコーター、フレキソ、エアナイフコーター、バーコーターなどの塗布手段により塗布し、乾燥することにより形成できる。感圧接着剤組成物の塗布量は、接着層の接着性、剥離性、透明性等の観点より、好ましくは１〜５ｇ／ｍ2（固形分換算）、より好ましくは２〜３ｇ／ｍ2（固形分換算）である。
