Description
乾式電子写真方式用のプリンターラベル等に使用される粘着体及び剥離シートに関する。 The present invention relates to a pressure-sensitive adhesive body and a release sheet used for printer labels for dry electrophotographic systems.
乾式電子写真方式用のプリンターラベル等に使用される粘着体は、剥離シートに粘着シートが貼着されて構成され、粘着シートの一部が耳部としてカス取りされ、残った粘着シートの基材が、印刷が施されるためのラベル部として使用される。このような用途で使用される粘着体は、プリンターにおける走行性を良好にし、紙詰まりを防止するために、剥離シートに高い滑り性が要求される。 The pressure-sensitive adhesive used for printer labels for dry electrophotographic systems is composed of a pressure-sensitive adhesive sheet attached to a release sheet, part of the pressure-sensitive adhesive sheet is removed as an ear, and the remaining base material of the pressure-sensitive adhesive sheet Is used as a label for printing. The pressure-sensitive adhesive body used in such applications is required to have high slipperiness in the release sheet in order to improve running performance in the printer and prevent paper jamming.
また、近年、粘着体は、環境への負荷低減が要求されつつあり、剥離剤に無溶剤タイプのシリコーンが使用されつつあり、粘着剤にはエマルションタイプのものの使用が検討されつつある。 In recent years, pressure-sensitive adhesives are being demanded to reduce the burden on the environment. Solvent-free silicone is being used as a release agent, and the use of emulsion-type adhesives is being studied.
特許文献１には、剥離シートの滑り性を向上するための無溶剤タイプの剥離剤組成物が開示されている。ここでは、分子鎖末端にアルケニル基を有する低分子オルガノポリシロキサンと、高分子オルガノポリシロキサンとを含む剥離剤組成物において、低分子オルガノポリシロキサンのアルケニル基の１分子当たりの個数を２個より少なくし、これにより剥離シートの滑り性を改善している。 Patent Document 1 discloses a solventless release agent composition for improving the slipperiness of the release sheet. Here, in the release agent composition containing a low molecular organopolysiloxane having an alkenyl group at the molecular chain terminal and a high molecular organopolysiloxane, the number of alkenyl groups of the low molecular organopolysiloxane per molecule is more than 2. This reduces the slipperiness of the release sheet.
また、特許文献２には、分岐構造を有し、分子鎖末端にのみアルケニル基を有する低粘度ジオルガノポリシロキサンをベースとする無溶剤タイプの剥離剤組成物において、分子鎖末端にのみアルケニル基を有する高粘度ジオルガノポリシロキサンを添加することにより、剥離シートに滑り性が付与できる構成が開示されている。
しかし、特許文献１では、剥離シートの滑り性が改善されるが、低速剥離時の剥離力が小さく設定されているので、印刷中やラベル搬送中にラベル部が剥離シートからめくれ易くなり、搬送不良等のトラブルが生じやくなる。また、高速剥離時の剥離力が大きく設定されているので、高速で粘着シートを剥離させると粘着シートが切れやくなり、高速でカス取りが行えないという問題がある。特許文献２でも、剥離力の速度依存性について考慮されておらず、同様の問題が発生する虞がある。 However, in Patent Document 1, the slipperiness of the release sheet is improved, but since the release force during low-speed release is set to be small, the label portion is easily turned from the release sheet during printing or label transport, Troubles such as defects are likely to occur. Moreover, since the peeling force at the time of high-speed peeling is set to be large, there is a problem that if the pressure-sensitive adhesive sheet is peeled off at high speed, the pressure-sensitive adhesive sheet is broken and cannot be removed at high speed. Even in Patent Document 2, the speed dependency of the peeling force is not taken into consideration, and the same problem may occur.
そこで、本発明は上記問題点に鑑みてなされたものであり、剥離シートの滑り性を改善すると共に、低速剥離時の剥離力を所定のレベルに保ち、かつ高速剥離時の剥離力を抑えることができる無溶剤タイプの剥離剤組成物を用いた粘着体を提供することを目的とする。 Therefore, the present invention has been made in view of the above problems, and improves the slipperiness of the release sheet, keeps the release force at a low speed release at a predetermined level, and suppresses the release force at a high speed release. An object of the present invention is to provide a pressure-sensitive adhesive body using a solventless type release agent composition that can be used.
本発明に係る粘着体は、剥離シート基材の一方の面に剥離剤層を備えた剥離シートに、粘着シート基材の一方の面に粘着剤層を備えた粘着シートを、剥離剤層に粘着剤層が接するように、貼着されて構成される粘着体において、剥離剤層が、質量平均分子量１０００〜２０，０００の１分子中に少なくとも２個のアルケニル基を有する低分子オルガノポリシロキサンと、質量平均分子量５０，０００〜５００，０００の高分子直鎖状オルガノポリシロキサンとを含む付加反応型無溶剤タイプの剥離剤組成物が硬化被膜して形成されることを特徴とする。 The pressure-sensitive adhesive body according to the present invention has a pressure-sensitive adhesive sheet provided with a pressure-sensitive adhesive layer on one surface of a pressure-sensitive adhesive sheet base material, and a pressure-sensitive adhesive sheet provided on one surface of the pressure-sensitive adhesive sheet base material. Low molecular weight organopolysiloxane in which the release agent layer has at least two alkenyl groups in one molecule having a mass average molecular weight of 1000 to 20,000 in the pressure-sensitive adhesive body constituted so as to be in contact with the pressure-sensitive adhesive layer And an addition-reaction type solventless release agent composition comprising a high-molecular-weight linear organopolysiloxane having a mass average molecular weight of 50,000 to 500,000.
上記高分子直鎖状オルガノポリシロキサンは、充分な滑り性を発現させるために、アルケニル基を少なくすることが好ましく、分子末端のみにアルケニル基を有し、又はアルケニル基を有さないことが好ましい。分子末端のみにアルケニル基を有する場合、例えば、１分子中の各分子末端は１〜３個のアルケニル基を有する。剥離剤組成物の硬化前の粘度は、例えば５０〜３０００ｍＰａ・ｓである。また、例えば、剥離シートの剥離剤層表面とポリエチレンテレフタレートとの動摩擦係数はＪＩＳ Ｐ８１４７に準じた測定法において、０．１〜０．６となる。 In order to express sufficient slipperiness, the polymer linear organopolysiloxane preferably has a small number of alkenyl groups, preferably has an alkenyl group only at the molecular end or no alkenyl group. . When it has an alkenyl group only at the molecular end, for example, each molecular end in one molecule has 1 to 3 alkenyl groups. The viscosity of the release agent composition before curing is, for example, 50 to 3000 mPa · s. Further, for example, the dynamic friction coefficient between the release agent layer surface of the release sheet and polyethylene terephthalate is 0.1 to 0.6 in the measurement method according to JIS P8147.
また上記粘着剤層は、アクリル系エマルション粘着剤で構成されることが好ましく、アクリル系エマルション粘着剤は、官能基含有モノマーを０．３〜５．０質量％含むアクリル酸エステル系共重合体を含むエマルション粘着剤であることが好ましい。アクリル系エマルション粘着剤と上記剥離剤組成物の組み合わせにより、低速剥離時の剥離力を所定のレベルに保ち、かつ高速剥離時の剥離力を充分に抑えることが可能となる。また、このような構成によれば、剥離剤層及び粘着剤層に、有機溶剤を使用しなくても良くなるので、環境負荷を低減することができる。 Moreover, it is preferable that the said adhesive layer is comprised with an acryl-type emulsion adhesive, and an acryl-type emulsion adhesive is an acrylate-type copolymer containing 0.3-5.0 mass% of functional group containing monomers. It is preferable that it is an emulsion adhesive containing. By the combination of the acrylic emulsion pressure-sensitive adhesive and the release agent composition, it is possible to keep the release force at a low speed release at a predetermined level and sufficiently suppress the release force at a high speed release. Moreover, according to such a structure, since it becomes unnecessary to use an organic solvent for a release agent layer and an adhesive layer, an environmental load can be reduced.
本発明においては、温度２３℃、湿度５０％の環境下において、剥離速度０．３ｍ／分、剥離方向１８０°の条件で測定される、剥離シートの粘着シートに対する剥離力は、５０〜１５００ｍＮ／５０ｍｍであることが好ましい。また、温度２３℃、湿度５０％の環境下において、剥離速度１００ｍ／分、剥離方向１８０°の条件で測定される、剥離シートの粘着シートに対する剥離力は、１００〜３０００ｍＮ／５０ｍｍであることが好ましい。 In this invention, the peeling force with respect to the adhesive sheet of a peeling sheet measured by the conditions of peeling speed 0.3m / min and peeling direction 180 degrees in the environment of temperature 23 degreeC and humidity 50% is 50-1500mN /. It is preferable that it is 50 mm. Moreover, the peeling force with respect to the adhesive sheet of a peeling sheet measured by the conditions of a peeling speed of 100 m / min and a peeling direction of 180 degrees in an environment of a temperature of 23 ° C. and a humidity of 50% is 100 to 3000 mN / 50 mm. preferable.
本発明においては、剥離シートの幅方向における両端部には、粘着体を長手方向に送るための送り孔部が穿設され、粘着シートは、その一部が耳部として剥離シートから取り除かれて、剥離シートに残された部分が印刷が施されるためのラベル部として使用されることが好ましい。 In the present invention, feed hole portions for feeding the adhesive body in the longitudinal direction are formed at both ends in the width direction of the release sheet, and the adhesive sheet is partially removed from the release sheet as an ear portion. The portion left on the release sheet is preferably used as a label portion for printing.
本発明に係る剥離シートは、剥離シート基材の一方の面に剥離剤層を備えた剥離シートにおいて、剥離剤層が、質量平均分子量１０００〜２０，０００の１分子中に少なくとも２個のアルケニル基を有する低分子オルガノポリシロキサンと、質量平均分子量５０，０００〜５００，０００の高分子直鎖状オルガノポリシロキサンとを含む付加反応型無溶剤タイプの剥離剤組成物が硬化被膜して形成されることを特徴とする。 The release sheet according to the present invention is a release sheet having a release agent layer on one surface of a release sheet substrate, wherein the release agent layer has at least two alkenyl groups in one molecule having a mass average molecular weight of 1000 to 20,000. An addition reaction type solventless release agent composition comprising a low molecular weight organopolysiloxane having a group and a high molecular weight linear organopolysiloxane having a mass average molecular weight of 50,000 to 500,000 is formed by curing. It is characterized by that.
本発明においては、低分子オルガノポリシロキサンに、高分子量の直鎖状オルガノポリシロキサンを添加した剥離剤組成物を剥離シートに用いることにより、剥離シートの滑り性が良好で、かつ低速及び高速剥離時に適正な剥離力を有する粘着体を得ることができる。また、この剥離シートに、エマルションタイプの粘着剤、特に官能基含有モノマーを０．３〜５．０質量％含むアクリル酸エステル系共重合体を含むアクリル系エマルション粘着剤を用いた粘着シートを組み合わせることにより、特に適正な剥離力を有する粘着体を得ることができる。さらには、無溶剤系剥離剤及びエマルション粘着剤を用いることにより、環境負荷の少ない粘着体を提供することができる。 In the present invention, by using a release agent composition in which a high molecular weight linear organopolysiloxane is added to a low molecular weight organopolysiloxane for a release sheet, the release sheet has good slipperiness, and low speed and high speed release. Sometimes a pressure-sensitive adhesive body having an appropriate peeling force can be obtained. Also, this release sheet is combined with an emulsion-type pressure-sensitive adhesive, particularly a pressure-sensitive adhesive sheet using an acrylic emulsion pressure-sensitive adhesive containing an acrylic ester-based copolymer containing 0.3 to 5.0% by mass of a functional group-containing monomer. In this way, it is possible to obtain a pressure-sensitive adhesive body having a particularly appropriate peeling force. Furthermore, by using a solvent-free release agent and an emulsion pressure-sensitive adhesive, it is possible to provide a pressure-sensitive adhesive body with little environmental load.
以下本発明について、実施形態を用いてさらに詳細に説明する。

Innumerable feed holes 44 are formed along the vertical direction in FIG. The printer label is transported in the longitudinal direction of the label when the feed hole 44 is fitted into, for example, a feed pin (not shown) inside the printer, and the feed pin moves, and the label portion is printed by the printing unit (not shown). Printing is performed on the upper surface of 42 base materials 21.
ラベル部４２は、図２において、幅方向において３つ離間して並べられたが、この構成に限定されず、幅方向において１つ以上並べられればいくつ並べられても良いし、ラベル部同士が離間されていなくても良い。長手方向においても同様に隣接するラベル部４２は離間していなくても良い。また、送り孔４４は、耳部４３が剥離された後に、形成されても良いし、剥離される前から形成されていても良い。 In FIG. 2, three label portions 42 are arranged apart from each other in the width direction. However, the present invention is not limited to this configuration, and any number of label portions 42 may be arranged as long as one or more labels are arranged in the width direction. It does not need to be separated. Similarly in the longitudinal direction, the adjacent label portions 42 may not be separated from each other. Further, the feed hole 44 may be formed after the ear portion 43 is peeled off, or may be formed before being peeled off.
剥離シート１３は、剥離シート基材１１上に、付加反応型無溶剤タイプの剥離剤組成物が塗布された後、熱硬化によって硬化被膜して剥離剤層１２が剥離シート基材１１上に形成することにより作製される。 The release sheet 13 is coated on the release sheet substrate 11 with an addition reaction type solventless release agent composition, and then cured by thermal curing to form a release agent layer 12 on the release sheet substrate 11.

剥離剤組成物は、低分子オルガノポリシロキサンを主ポリマーとし、高分子直鎖状オルガノポリシロキサン、架橋剤、及び触媒が添加されたものであり、更に所望により、反応抑制剤、剥離調整剤、密着向上剤などが添加されていても良い。また、剥離剤塗工後の硬化工程で、加熱に加えて紫外線照射を行う場合、光開始剤が添加されていても良い。 The release agent composition comprises a low-molecular-weight organopolysiloxane as a main polymer, and a polymer linear organopolysiloxane, a crosslinking agent, and a catalyst added thereto, and, if desired, a reaction inhibitor, a release adjusting agent, An adhesion improver or the like may be added.

低分子オルガノポリシロキサンとしては、質量平均分子量１０００〜２０，０００の１分子中に少なくとも２個のアルケニル基を有するオルガノポリシロキサンが使用され、このオルガノポリシロキサンは例えば一般式（I）で示される。 As the low molecular weight organopolysiloxane, an organopolysiloxane having at least two alkenyl groups in one molecule having a mass average molecular weight of 1000 to 20,000 is used. The organopolysiloxane is represented by, for example, the general formula (I). .
Ｒ1Ｒ2 2ＳｉＯ（ＲＲＳｉＯ）m（ＲＲ2ＳｉＯ）nＳｉＲ2 2Ｒ1 ・・・（I）
ここで、Ｒは脂肪族不飽和結合を有しない同一又は異種の一価炭化水素、Ｒ1はアルケニル基、Ｒ2はＲ又はＲ1であり、ｍ及びｎは自然数を表し、１２≦（ｍ＋ｎ）≦２７０である。
R 1 R 2 2 SiO (RRSiO) m (RR 2 SiO) n SiR 2 2 R 1 (I)
Here, R is the same or different monovalent hydrocarbon having no aliphatic unsaturated bond, R 1 is an alkenyl group, R 2 is R or R 1 , m and n represent natural numbers, and 12 ≦ (m + n ) ≦ 270.
Ｒ1で示されるアルケニル基としては、ビニル基、アリル基、プロペニル基、ヘキセニル基など炭素数２〜１０のものが例示される。Ｒは炭素数１〜１２、好ましくは１〜１０であり、例えばメチル基、エチル基、プロピル基等のアルキル基、フェニル基、トリル基等のアリール基などが挙げられるが、硬化性、剥離性の点から８０モル％以上がメチル基であることが好ましい。また、低分子オルガノポリシロキサンの粘度は、例えば１０〜３００ｍＰａ・ｓである。 Examples of the alkenyl group represented by R 1 include those having 2 to 10 carbon atoms such as a vinyl group, an allyl group, a propenyl group, and a hexenyl group. R has 1 to 12 carbon atoms, preferably 1 to 10 carbon atoms, and examples thereof include alkyl groups such as a methyl group, an ethyl group and a propyl group, and aryl groups such as a phenyl group and a tolyl group. From this point, it is preferable that 80 mol% or more is a methyl group. The viscosity of the low molecular organopolysiloxane is, for example, 10 to 300 mPa · s.
高分子直鎖状オルガノポリシロキサンとしては、質量平均分子量５０，０００〜５００，０００のものが使用され、例えば、１分子中の各分子鎖末端のみに１〜３個のアルケニル基を有するもの、又はアルケニル基を有しないものが使用され、一般式（II）で示されるものが使用される。 As the polymer linear organopolysiloxane, those having a mass average molecular weight of 50,000 to 500,000 are used, for example, those having 1 to 3 alkenyl groups only at the end of each molecular chain in one molecule, Or what does not have an alkenyl group is used, and what is shown by general formula (II) is used.
Ｒ3 3ＳｉＯ（Ｒ2ＳｉＯ）pＳｉＲ3 3 ・・・（II）
ここで、Ｒは脂肪族不飽和結合を有しない同一又は異種の一価炭化水素、Ｒ3はビニル基等のアルケニル基、又は同一若しくは異種の一価炭化水素基であり、ｐは自然数を表し、７００≦ｐ≦７０００である。

一般式（II）で示されるように、高分子直鎖状オルガノポリシロキサンは、各分子鎖末端のみに１〜３個のアルケニル基を有し、又はアルケニル基を有さないことが好ましい。高分子直鎖状オルガノポリシロキサンは、１分子中のアルケニル基を少なくし、又はアルケニル基を有さないようにすることにより、その架橋密度が低くなるので、剥離剤層に充分な滑り性を発現させることができる。また、高分子直鎖状オルガノポリシロキサンは、アルケニル基を有さない場合、剥離剤層の滑り性が良好になる傾向にある一方、アルケニル基を有する場合、剥離剤の粘着シートへの転写が防止される傾向にある。 As shown by the general formula (II), the polymer linear organopolysiloxane preferably has 1 to 3 alkenyl groups only at the end of each molecular chain or has no alkenyl groups. The polymer linear organopolysiloxane has a low cross-link density by reducing the alkenyl groups in one molecule or not having alkenyl groups. Can be expressed. Moreover, when the polymer linear organopolysiloxane has no alkenyl group, the slipperiness of the release agent layer tends to be good, whereas when it has an alkenyl group, the transfer of the release agent to the adhesive sheet It tends to be prevented.
高分子直鎖状オルガノポリシロキサンの具体例としては、例えば、ジメチルポリシロキサン、ビニル基を各分子鎖末端のみに１個ずつ有するオルガノポリシロキサン等が挙げられる。高分子直鎖状オルガノポリシロキサンは、低分子オルガノポリシロキサン１００質量部に対して、好ましくは０．５〜１５質量部、特に好ましくは０．８〜１２質量部添加される。 Specific examples of the polymer linear organopolysiloxane include, for example, dimethylpolysiloxane and organopolysiloxane having one vinyl group only at each molecular chain terminal. The polymer linear organopolysiloxane is preferably added in an amount of 0.5 to 15 parts by mass, particularly preferably 0.8 to 12 parts by mass with respect to 100 parts by mass of the low molecular organopolysiloxane.
架橋剤としては、例えば１分子中に少なくとも２個のケイ素原子結合水素原子（ＳｉＨ）を有するポリオルガノハイドロジェンシロキサン、具体的にはジメチルハイドロジェンシロキシ基末端封鎖ジメチルシロキサン−メチルハイドロジェンシロキサン共重合体、トリメチルシロキシ基末端封鎖ジメチルシロキサン−メチルハイドロジェンシロキサン共重合体、トリメチルシロキシ基末端封鎖ポリ（メチルハイドロジェンシロキサン）、ポリ（ハイドロジェンシルセスキオキサン）等が挙げられる。本実施形態では、架橋剤のＳｉＨと、低分子オルガノポリシロキサン及び高分子直鎖状オルガノポリシロキサンのアルケニル基との付加反応により硬化被膜が形成される。 As a crosslinking agent, for example, polyorganohydrogensiloxane having at least two silicon-bonded hydrogen atoms (SiH) in one molecule, specifically, dimethylhydrogensiloxy group end-capped dimethylsiloxane-methylhydrogensiloxane copolymer Examples thereof include a compound, a trimethylsiloxy group end-capped dimethylsiloxane-methylhydrogensiloxane copolymer, a trimethylsiloxy group end-capped poly (methylhydrogensiloxane), and poly (hydrogensilsesquioxane). In this embodiment, a cured film is formed by an addition reaction between the crosslinking agent SiH and the alkenyl group of the low-molecular-weight organopolysiloxane and the high-molecular-weight linear organopolysiloxane.
架橋剤は、剥離剤組成物中において、ケイ素原子結合水素原子の数が、アルケニル基の数に対して、０．８〜５．０（モル比）になるように添加されることが好ましい。モル比が０．８より低いと当該組成物の硬化性が低下し、５．０より高いと剥離剤の剥離力が重くなり、剥離性能が悪化する虞がある。 In the release agent composition, the crosslinking agent is preferably added so that the number of silicon-bonded hydrogen atoms is 0.8 to 5.0 (molar ratio) with respect to the number of alkenyl groups. When the molar ratio is lower than 0.8, the curability of the composition is lowered. When the molar ratio is higher than 5.0, the peeling force of the release agent becomes heavy, and the peeling performance may be deteriorated.
触媒としては、例えば白金系化合物が用いられ、白金系化合物の例としては、微粒子状白金、炭素粉末担体上に吸着された微粒子状白金、塩化白金酸、アルコール変性塩化白金酸、塩化白金酸のオレフィン錯体、パラジウム、ロジウム触媒等が挙げられる。触媒は、付加反応型のオルガノポリシロキサン及び架橋剤の合計量に対し、白金系金属として１〜１０００ｐｐｍ程度添加される。 As the catalyst, for example, a platinum compound is used. Examples of the platinum compound include fine platinum, fine platinum adsorbed on a carbon powder carrier, chloroplatinic acid, alcohol-modified chloroplatinic acid, and chloroplatinic acid. Examples include olefin complexes, palladium and rhodium catalysts. About 1 to 1000 ppm of the catalyst is added as a platinum-based metal with respect to the total amount of the addition reaction type organopolysiloxane and the crosslinking agent.
剥離剤組成物の硬化前の粘度は、５０〜３０００ｍＰａ・ｓであることが好ましく、８０〜２５００ｍＰａ・ｓであることがより好ましく、特に好ましくは１００〜２０００ｍＰａ・ｓである。粘度が上記下限値より低くなると、剥離シート基材に紙を使用した場合に剥離剤組成物が剥離シート基材に染み込みやすくなり、上限値より高いと剥離シート基材への剥離剤組成物の塗工が難しくなる。 The viscosity of the release agent composition before curing is preferably 50 to 3000 mPa · s, more preferably 80 to 2500 mPa · s, and particularly preferably 100 to 2000 mPa · s. When the viscosity is lower than the lower limit, the release agent composition is likely to penetrate into the release sheet substrate when paper is used for the release sheet substrate, and when the viscosity is higher than the upper limit, the release agent composition of the release sheet substrate Coating becomes difficult.
剥離剤層１２の塗布量は、特に限定されないが、０．０５〜５ｇ／ｍ2であるのが好ましく、０．１〜３ｇ／ｍ2であるのがより好ましい。 The coating amount of the release agent layer 12 is not particularly limited, but is preferably 0.05-5 g / m 2, and more preferably 0.1 to 3 g / m 2.
剥離剤組成物を剥離シート基材１１上に塗工する方法としては、例えば、グラビアコート法、バーコート法、スプレーコート法、スピンコート法、ナイフコート法、ロールコート法、ダイコート法等の既存の方法が使用できる。 Examples of methods for applying the release agent composition onto the release sheet substrate 11 include existing methods such as gravure coating, bar coating, spray coating, spin coating, knife coating, roll coating, and die coating. Can be used.
上記剥離剤組成物が使用されることにより、剥離シート１３の動摩擦係数が以下のように設定され、剥離シート１３の滑り性が良好になる。例えば、剥離シートの剥離剤表面とポリエチレンテレフタレートとの動摩擦係数は、ＪＩＳ Ｐ８１４７に準じた測定法において、０．１〜０．６となり、その上限値は好ましくは０．５５、特に好ましくは０．５となり、また、その下限値は好ましくは０．１５、特に好ましくは０．２となる。動摩擦係数が上記上限値を超えると、粘着体２０の走行性が悪くなり、プリンター内部における紙詰まり等が発生しやすくなる。また、動摩擦係数が上記下限値より低くなると、例えば生産工程において、剥離シートがロールに巻き取られる際、巻きずれが起こる虞がある。 By using the release agent composition, the dynamic friction coefficient of the release sheet 13 is set as follows, and the slipperiness of the release sheet 13 is improved. For example, the dynamic friction coefficient between the release agent surface of the release sheet and polyethylene terephthalate is 0.1 to 0.6 in the measurement method according to JIS P8147, and the upper limit is preferably 0.55, particularly preferably 0.8. The lower limit is preferably 0.15, particularly preferably 0.2. When the dynamic friction coefficient exceeds the above upper limit value, the traveling property of the pressure-sensitive adhesive body 20 is deteriorated, and a paper jam or the like in the printer tends to occur. Moreover, when a dynamic friction coefficient becomes lower than the said lower limit, when a peeling sheet is wound up by a roll, for example in a production process, there exists a possibility that winding | disengagement may occur.
粘着シート２３は、粘着シート基材２１上に、粘着剤が塗布されて、粘着剤層２２が粘着シート基材２１上に形成されることにより作製される。その後、粘着シート２３は、粘着剤層２２が剥離剤層１２に接するように、剥離シート１３と粘着シート２３が貼り合わせられ、粘着体１０が作製される。なお、剥離シート１３の剥離剤層１２の上に、粘着剤を塗布して粘着剤層２２を形成し、次いで、粘着剤層２２の上に粘着シート基材２１を貼着させることにより粘着体１０を作製してもよい。 The pressure-sensitive adhesive sheet 23 is produced by applying a pressure-sensitive adhesive on the pressure-sensitive adhesive sheet substrate 21 and forming the pressure-sensitive adhesive layer 22 on the pressure-sensitive adhesive sheet substrate 21. Thereafter, the pressure-sensitive adhesive sheet 23 is bonded to the release sheet 13 and the pressure-sensitive adhesive sheet 23 so that the pressure-sensitive adhesive layer 22 is in contact with the release agent layer 12. An adhesive is formed by applying an adhesive on the release agent layer 12 of the release sheet 13 to form an adhesive layer 22, and then attaching an adhesive sheet substrate 21 on the adhesive layer 22. 10 may be produced.
粘着剤を塗工する方法としては、例えば、グラビアコート法、バーコート法、スプレーコート法、スピンコート法、ナイフコート法、ロールコート法、ダイコート法等の既存の方法が使用できる。 As a method for applying the pressure-sensitive adhesive, existing methods such as a gravure coating method, a bar coating method, a spray coating method, a spin coating method, a knife coating method, a roll coating method, and a die coating method can be used.
粘着シート基材２１は粘着剤層２２を支持する機能を有しており、例えば、上質紙、クラフト紙、グラシン紙、合成紙等の紙、ポリエチレンテレフタレートフィルム、ポリブチレンテレフタレートフィルム、ポリエチレンフィルム、ポリプロピレンフィルム、ポリメチルペンテンフィルム、ポリカーボネートフィルム等のプラスチックフィルム、アルミニウム、ステンレス等の金属箔等の単体もしくは複合物で構成されている。粘着シート基材２１は、その表面または裏面に、印刷インクまたは粘着剤層２２の密着をよくする等の目的で、表面処理が施されていてもよい。 The pressure-sensitive adhesive sheet substrate 21 has a function of supporting the pressure-sensitive adhesive layer 22. For example, paper such as fine paper, kraft paper, glassine paper, synthetic paper, polyethylene terephthalate film, polybutylene terephthalate film, polyethylene film, polypropylene It is composed of a simple substance or a composite such as a film, a plastic film such as a polymethylpentene film or a polycarbonate film, or a metal foil such as aluminum or stainless steel. The pressure-sensitive adhesive sheet substrate 21 may be subjected to surface treatment for the purpose of improving the adhesion of the printing ink or the pressure-sensitive adhesive layer 22 on the front surface or the back surface thereof.
粘着剤としては、アクリル系エマルション粘着剤が使用される。アクリル系エマルション粘着剤は、官能基含有モノマーと、アクリル酸エステル、メタアクリル酸エステル等の他のモノマーとを共重合して得られるアクリル系共重合体を主成分として構成され、溶媒として水を含み、乳化剤、増粘剤等の所望の添加剤が適宜含まれており、必要に応じて、安定剤、粘着付与剤、充填剤、着色剤、酸化防止剤、帯電防止剤、紫外線吸収剤等をさらに含んでいてもよい。官能基含有モノマーとしては、例えばアクリル酸、メタアクリル酸等のカルボキシル基含有モノマーが挙げられる。官能基含有モノマーは、アクリル酸エステル系共重合体を構成するモノマー全体を基準（１００質量％）として、０．３〜５．０質量％含むことが好ましい。 An acrylic emulsion adhesive is used as the adhesive. The acrylic emulsion pressure-sensitive adhesive is composed mainly of an acrylic copolymer obtained by copolymerizing a functional group-containing monomer and another monomer such as an acrylic ester or methacrylic ester, and water as a solvent. Contains desired additives such as emulsifiers, thickeners, etc., as necessary, stabilizers, tackifiers, fillers, colorants, antioxidants, antistatic agents, ultraviolet absorbers, etc. May further be included. Examples of the functional group-containing monomer include carboxyl group-containing monomers such as acrylic acid and methacrylic acid. It is preferable that a functional group containing monomer contains 0.3-5.0 mass% on the basis (100 mass%) of the whole monomer which comprises an acrylate-type copolymer.
粘着剤層２２の塗布量は、特に限定されないが、５〜６０ｇ／ｍ2であるのが好ましく、１０〜４０ｇ／ｍ2であるのがより好ましい。 The coating amount of the adhesive layer 22 is not particularly limited, but is preferably 5 to 60 g / m 2, and more preferably 10 to 40 g / m 2.
本実施形態では、粘着剤をエマルションで構成することにより、粘着剤層及び剥離剤層のいずれにも有機溶剤を使用しなくて良いので、環境負荷を低減することができる。また、アクリル系エマルション粘着剤から形成される粘着剤層と、上記剥離剤組成物から形成される剥離剤層とを組み合わせて使用し、かつ粘着剤の官能基含有モノマーの含有量を上述した所定の範囲内にすることにより、高速剥離時、及び低速剥離時の剥離シートの剥離力を、所望の範囲に設定することができる。 In this embodiment, by constituting the pressure-sensitive adhesive with an emulsion, it is not necessary to use an organic solvent for both the pressure-sensitive adhesive layer and the release agent layer, so that the environmental burden can be reduced. Further, the pressure-sensitive adhesive layer formed from the acrylic emulsion pressure-sensitive adhesive and the release agent layer formed from the release agent composition are used in combination, and the content of the functional group-containing monomer of the pressure-sensitive adhesive is the above-mentioned By making it within this range, the peeling force of the release sheet at the time of high-speed peeling and at the time of low-speed peeling can be set to a desired range.
すなわち、温度２３℃、湿度５０％の環境下において、剥離速度０．３ｍ／分、剥離方向１８０°の条件で測定された、剥離シートの粘着シートに対する剥離力（以下、低速剥離力という）は、５０〜１５００ｍＮ／５０ｍｍとなり、好ましくは８０〜１２００ｍＮ／５０ｍｍ、最も好ましくは１００〜１０００ｍＮ／５０ｍｍとなる。上記上限値を超えると、低速剥離力が高くなりすぎ、ユーザーがラベル部を剥がすとき、無理な負荷をかけなければならず、ラベル部が剥がしにくくなる。また、下限値を下回ると、印刷中や搬送中に、ラベル部が剥離シートからめくれやすくなり、搬送不良等が生じやすくなる。 That is, in an environment of a temperature of 23 ° C. and a humidity of 50%, the peel force of the release sheet to the pressure-sensitive adhesive sheet (hereinafter referred to as low-speed peel force) measured under the conditions of a peel speed of 0.3 m / min and a peel direction of 180 ° is 50 to 1500 mN / 50 mm, preferably 80 to 1200 mN / 50 mm, and most preferably 100 to 1000 mN / 50 mm. When the above upper limit is exceeded, the low-speed peeling force becomes too high, and when the user peels off the label portion, an unreasonable load must be applied, and the label portion becomes difficult to peel off. On the other hand, when the value is below the lower limit value, the label portion is likely to be turned from the release sheet during printing or conveyance, and conveyance failure or the like is likely to occur.
また、温度２３℃、湿度５０％の環境下において、剥離速度１００ｍ／分、剥離方向１８０°の条件で測定された、剥離シートの粘着シートに対する剥離力（以下、高速剥離力という）は、１００〜３０００ｍＮ／５０ｍｍとなり、好ましくは１５０〜１８００ｍＮ／５０ｍｍ、特に好ましくは２００〜１６００ｍＮ／５０ｍｍとなり、高速剥離力は、低速剥離力の１〜３倍になることが好ましい。高速剥離力が上記下限値より低くなると、耳部をカス上げするときに、ラベル部が耳部と共に飛ぶ可能性が高くなる。また、上記上限値を超える場合、カス上げのときに高速で耳部（粘着シート）を剥離させると、粘着シートが途中で切れる可能性が高くなる。 In addition, the peel strength of the release sheet to the pressure-sensitive adhesive sheet (hereinafter referred to as high-speed peel force) measured under the conditions of a temperature of 23 ° C. and a humidity of 50% and a peel speed of 100 m / min and a peel direction of 180 ° is 100 -3000 mN / 50 mm, preferably 150-1800 mN / 50 mm, particularly preferably 200-1600 mN / 50 mm, and the high-speed peeling force is preferably 1 to 3 times the low-speed peeling force. If the high-speed peeling force is lower than the lower limit value, the possibility that the label part will fly together with the ear part when the ear part is lifted is increased. Moreover, when exceeding the said upper limit, if an ear | edge part (adhesive sheet) is peeled at high speed at the time of scrap raising, possibility that an adhesive sheet will be cut in the middle becomes high.

（１）残留接着率測定
幅２５ｍｍ、長さ２０ｃｍの剥離シートの剥離剤層側の面に、ポリエステルテープ（製品名：NO.31B、日東電工社製）を貼り合わせ、その上に２０ｇ／ｃｍ2の荷重をかけて、７０℃で２４時間エージングを行った後、ポリエステルテープを剥離シートから剥がして、ステンレス板に貼り付けた。このポリエステルテープをステンレス板から１８０°の角度で速度０．３ｍ／分にて剥がした時の抵抗力（Ａ）を測定した。ブランクとして剥離シートに貼り合わしていないポリエステルテープをステンレス板に貼り合わせて同様に抵抗力（Ｂ）を測定した。そして、残留接着率を１００×（Ａ／Ｂ）として表した。残留接着率が９０％以上であれば、良好であるとして表１において○とした。８０％以上９０％未満であれば、使用可能であるとして△とした。８０％未満であれば使用不可能であるとして×とした。
(1) Residual adhesion rate measurement A polyester tape (product name: NO.31B, manufactured by Nitto Denko Corporation) is bonded to the surface of the release agent layer side of a release sheet having a width of 25 mm and a length of 20 cm, and 20 g / cm is formed thereon. After applying a load of 2 and aging at 70 ° C. for 24 hours, the polyester tape was peeled off from the release sheet and attached to a stainless steel plate. The resistance (A) when the polyester tape was peeled off from the stainless steel plate at an angle of 180 ° at a speed of 0.3 m / min was measured. A polyester tape not bonded to a release sheet as a blank was bonded to a stainless steel plate, and the resistance (B) was measured in the same manner. The residual adhesion rate was expressed as 100 × (A / B). If the residual adhesion rate is 90% or more, it is judged as good in Table 1 as being good. If it was 80% or more and less than 90%, it was marked as Δ because it was usable. If it was less than 80%, it was marked as x because it could not be used.
（２）滑り性試験
各剥離シートについて、ＪＩＳ Ｐ８１４７に準じて動摩擦係数を測定した。まず、底面６ｃｍ×１０ｃｍ、高さ２ｃｍの金属片（１０００ｇ）の底面にポリエチレンテレフタレートフィルムを貼り合わせた。この金属片を、剥離シートの剥離剤層側の面上に、貼り付けたフィルムが剥離剤層に接するように載せた。引張り試験機を用いて、水平方向に１．０ｍ／分の速度で金属片を引っ張り、安定状態になったときの力Ｆ（Ｎ）を測定し、Ｆ／（１０００×９．８×１０-3）を動摩擦係数とした。動摩擦係数が０．１以上０．６以下であれば良好であるとして表１には○とした。０．１未満または０．６を超える場合であれば使用不可能として×にした。
(2) Slip property test About each peeling sheet, the dynamic friction coefficient was measured according to JISP8147. First, a polyethylene terephthalate film was bonded to the bottom surface of a metal piece (1000 g) having a bottom surface of 6 cm × 10 cm and a height of 2 cm. This metal piece was placed on the surface of the release sheet on the release agent layer side so that the attached film was in contact with the release agent layer. Using a tensile tester, the metal piece was pulled in the horizontal direction at a speed of 1.0 m / min, and the force F (N) when the metal piece was in a stable state was measured, and F / (1000 × 9.8 × 10 − 3 ) was defined as the dynamic friction coefficient. In Table 1, it was marked as “good” if the dynamic friction coefficient was 0.1 or more and 0.6 or less. If it was less than 0.1 or more than 0.6, it was marked as unusable.
（３）紙詰まり試験
各粘着体について、その幅方向の両端部に送り孔を形成すると共に、抜き加工及びカス取りを行い、図２に示すようなプリンターラベルを作製した。印刷機（商品名：VSP-4971、富士通社製）を用いて、プリンターラベルに印刷を施したときに紙詰まりが起こるかどうかのテストを行った。テストは、速度８２００行／分、テスト時間１０分で行った。
(3) Paper jam test For each pressure-sensitive adhesive body, feed holes were formed at both ends in the width direction, and punching and scrap removal were performed to produce a printer label as shown in FIG. Using a printing machine (trade name: VSP-4971, manufactured by Fujitsu Limited), a test was performed to determine whether a paper jam occurred when printing was performed on the printer label. The test was performed at a speed of 8200 lines / minute and a test time of 10 minutes.
（４）剥離力測定
各粘着体について剥離力を測定した。剥離力の測定は、温度２３℃湿度５０％の環境で１日放置後、３０日放置後それぞれの粘着体について行った。粘着体は幅２０ｍｍ、長さ２００ｍｍに裁断し、引っ張り試験機によって、剥離シートを固定し、粘着シートを所定の剥離速度で１８０°方向に引っ張ることにより、粘着シートに対する剥離シートの剥離力を測定した。このとき、剥離速度を０．３ｍ／分、１００ｍ／分それぞれに設定し、温度２３℃、湿度５０％の環境下で低速剥離力及び高速剥離力の測定を行った。
(4) Measurement of peeling force The peeling force was measured for each pressure-sensitive adhesive body. The peel force was measured for each pressure-sensitive adhesive after being left for 1 day in an environment of a temperature of 23 ° C. and a humidity of 50%, and then left for 30 days. The adhesive body is cut into a width of 20 mm and a length of 200 mm, the release sheet is fixed by a tensile tester, and the adhesive sheet is pulled in a 180 ° direction at a predetermined release speed, thereby measuring the peeling force of the release sheet to the adhesive sheet. did. At this time, the peeling speed was set to 0.3 m / min and 100 m / min, respectively, and the low speed peeling force and the high speed peeling force were measured in an environment of a temperature of 23 ° C. and a humidity of 50%.
表１から明らかなように、分子量５０，０００〜５００，０００の高分子直鎖状オルガノポリシロキサンを添加した実施例１〜１０は、残留接着率及び滑り性のいずれもが良好な結果となった。また、高分子直鎖状オルガノポリシロキサンの添加量が同一である場合、滑り性は、その分子量が高いほうが良好であった。また、分子量が同一である場合、高分子直鎖状オルガノポリシロキサンがアルケニル基を含有しているとき、アルケニル基を含有していないときに比べ、残留接着率が高くなると共に、滑り性が低くなる傾向となった。 As apparent from Table 1, Examples 1 to 10 to which a high molecular weight linear organopolysiloxane having a molecular weight of 50,000 to 500,000 was added had good results in both the residual adhesion rate and the slipperiness. It was. Moreover, when the addition amount of the polymer linear organopolysiloxane was the same, the higher the molecular weight, the better the slipping property. Also, when the molecular weight is the same, when the polymer linear organopolysiloxane contains an alkenyl group, the residual adhesion rate is higher and the slipperiness is lower than when the alkenyl group is not contained. It became a tendency to become.
それに対して、剥離剤が分子量５０，０００〜５００，０００の高分子直鎖状オルガノポリシロキサンを含まない比較例１，２では、滑り性が悪く、紙詰まり試験において紙詰まりが発生した。また、比較例３のように、分子量が低い直鎖状オルガノポリシロキサンを多量に添加すると、滑り性が良好となったが、残留接着率が低く使用可能なレベルにならなかった。 On the other hand, in Comparative Examples 1 and 2 in which the release agent did not contain a high molecular weight linear organopolysiloxane having a molecular weight of 50,000 to 500,000, the slipperiness was poor and paper jam occurred in the paper jam test. Further, as in Comparative Example 3, when a large amount of a linear organopolysiloxane having a low molecular weight was added, the slipping property was improved, but the residual adhesion rate was low and the level was not reached.
また、実施例１〜９では、官能基含有モノマーを１〜３質量％含む粘着剤を用いることにより、高速及び低速剥離力のいずれも適正な値となった。それに対して、実施例１０のように官能基含有モノマーの含有量を１０質量％とすると、実施例１と同一の剥離シートを用いたにもかかわらず、３０日後の高速及び低速剥離力のいずれもが重くなりすぎる結果となった。この結果から、本発明の剥離剤組成物に対しては、官能基含有モノマーの含有量が１〜５質量％程度であるアクリル系エマルション粘着剤を用いれば、高速及び低速剥離力のいずれもが適切になることが理解できる。 Moreover, in Examples 1-9, both the high-speed and low-speed peeling force became an appropriate value by using the adhesive containing 1-3 mass% of functional group containing monomers. On the other hand, when the content of the functional group-containing monomer is 10% by mass as in Example 10, regardless of whether the same release sheet as in Example 1 was used, either high speed or low speed release force after 30 days was used. The result was too heavy. From this result, for the release agent composition of the present invention, if an acrylic emulsion pressure-sensitive adhesive having a functional group-containing monomer content of about 1 to 5% by mass is used, both high-speed and low-speed release forces are obtained. Understand that it will be appropriate.
