Description
本発明は剥離シート及び粘着体に関するものであり、特に、粘着シートがラベル加工される用途で用いられる剥離シート及び粘着体に関する。 The present invention relates to a release sheet and a pressure-sensitive adhesive body, and particularly relates to a release sheet and a pressure-sensitive adhesive body that are used in applications where the pressure-sensitive adhesive sheet is labeled.
従来、粘着層を有する粘着シートと、紙基材上に剥離層が設けられた剥離シートとを備え、粘着層と剥離層が密着するように貼り合わされた粘着体が知られている。このような粘着体では、粘着シートを剥離シートから剥離した後においても、剥離シート上に粘着層の一部が残るいわゆる糊残り現象が発生する場合がある。糊残り現象は、紙基材上に設けられた剥離層にピンホールや凹凸ができてそこに粘着剤が入り込み、その入り込んだ粘着剤が、粘着シートを剥離シートから剥離する際に破断されて発生すると考えられている。 DESCRIPTION OF RELATED ART Conventionally, the adhesive body provided with the adhesive sheet which has an adhesion layer, and the peeling sheet in which the peeling layer was provided on the paper base material was bonded so that an adhesion layer and a peeling layer might adhere | attach was known. In such an adhesive body, even after the adhesive sheet is peeled from the release sheet, a so-called adhesive residue phenomenon in which a part of the adhesive layer remains on the release sheet may occur. The adhesive residue phenomenon is caused when pinholes and irregularities are formed in the release layer provided on the paper substrate, and the adhesive enters there, and the adhesive that enters is broken when the adhesive sheet is peeled from the release sheet. It is thought to occur.
粘着シート用の粘着剤は、溶剤型粘着剤が用いられるのが一般的であったが、近年、地球環境保護や労働環境等を改善させるために、水系のエマルション型に急速に転換されてきている。同様に、剥離シートに使用される剥離剤も、溶剤型剥離剤から無溶剤型剥離剤への転換が進んでいる。これら水系粘着剤や無溶剤型剥離剤が使用された粘着体では、糊残り現象が特に発生しやすくなる。 In general, solvent-type adhesives are used as adhesives for adhesive sheets, but in recent years, they have been rapidly converted to water-based emulsion types in order to improve the global environment and improve the working environment. Yes. Similarly, the release agent used for the release sheet is also being converted from a solvent-type release agent to a solventless release agent. In the pressure-sensitive adhesive body using these water-based pressure-sensitive adhesives and solvent-free release agents, the adhesive residue phenomenon is particularly likely to occur.
ところで、ラベル加工された粘着シートをラベリングする時に糊残り現象が発生すると、ラベリング後に剥離シートの剥離層面が接触するガイドローラ等に、粘着剤の一部が転着することがある。このような粘着剤の転着は、紙送り不良や、ラベラーの動作不良等を引き起こし、ラベリングの作業性を低下させる原因になる。 By the way, when an adhesive residue phenomenon occurs when labeling a pressure-sensitive adhesive sheet that has been subjected to labeling, a part of the pressure-sensitive adhesive may be transferred to a guide roller or the like that contacts the release layer surface of the release sheet after labeling. Such transfer of the pressure-sensitive adhesive causes a paper feed failure, a labeler operation failure, and the like, and causes a reduction in labeling workability.
従来、糊残り現象を防止するために、所定の紙基材に剥離剤樹脂を０．８〜１．５ｇ／ｍ２の坪量で塗布するとともに、剥離層の紙基材に含浸されていない部分（剥離剤単体層）の厚みを３０〜１５０ｎｍに調整した剥離シートが知られている（特許文献１参照）。 Conventionally, in order to prevent the adhesive residue phenomenon, a release resin is applied to a predetermined paper base at a basis weight of 0.8 to 1.5 g / m 2 and the paper base of the release layer is not impregnated. There is known a release sheet in which the thickness of a part (release agent single layer) is adjusted to 30 to 150 nm (see Patent Document 1).
しかし特許文献１の剥離シートでは、粘着シートを剥離シートから剥離したときの糊残りを十分に防止することができず、ラベリングの作業性を十分に向上させることができない。 However, the release sheet of Patent Document 1 cannot sufficiently prevent the adhesive residue when the pressure-sensitive adhesive sheet is peeled from the release sheet, and the workability of labeling cannot be sufficiently improved.
そこで、本発明は、例えばラベリングするときのように、粘着シートを剥離シートから剥離したときに、剥離シート上に残存する粘着剤の量を低減させることが可能な剥離シート、及び粘着体を提供することを目的とする。 Therefore, the present invention provides a release sheet and an adhesive body that can reduce the amount of adhesive remaining on the release sheet when the adhesive sheet is released from the release sheet, for example, when labeling. The purpose is to do.
本発明に係る剥離シートは、紙基材と、紙基材上に設けられた剥離層とを有し、剥離層が、シリコーン樹脂からなる剥離剤樹脂を含有し、剥離シートの剥離層が設けられた側の面が、平滑度２５００秒以上であるとともに、剥離層の坪量を坪量Ａ［ｇ／ｍ２］とし、紙基材に含浸されていない剥離層の剥離剤単体層の坪量を坪量Ｂ［ｇ／ｍ２］とした場合、質量比率Ｂ／Ａが０．２０〜０．８０であることを特徴とする。 The release sheet according to the present invention has a paper base material and a release layer provided on the paper base material, the release layer contains a release agent resin made of a silicone resin, and a release layer of the release sheet is provided. The surface of the release layer has a smoothness of 2500 seconds or more, the basis weight of the release layer is the basis weight A [g / m 2 ], and the basis weight of the release agent single layer of the release layer not impregnated in the paper substrate When the amount is a basis weight B [g / m 2 ], the mass ratio B / A is 0.20 to 0.80.
本発明に係る剥離シートは、紙基材の剥離層が設けられる側の面が、平滑度１０００秒以上で、透気度３１，０００秒以上であることが好ましい。例えば坪量Ａは、０．５０〜２．５０ｇ／ｍ２である。また坪量Ｂは例えば、０．２０〜２．００ｇ／ｍ２である。 In the release sheet according to the present invention, the surface of the paper base on which the release layer is provided preferably has a smoothness of 1000 seconds or more and an air permeability of 31,000 seconds or more. For example, the basis weight A is 0.50 to 2.50 g / m 2 . The basis weight B is, for example, 0.20 to 2.00 g / m 2 .
本発明に係る粘着体は、紙基材、及び紙基材上に設けられた剥離層を有する剥離シートと、剥離層上に設けられた粘着層とを有し、剥離層が、シリコーン樹脂からなる剥離剤樹脂を含有し、剥離シートの剥離層が設けられた側の面が、平滑度２５００秒以上であるとともに、剥離層の坪量を坪量Ａ［ｇ／ｍ２］とし、紙基材に含浸されていない剥離層の剥離剤単体層の坪量を坪量Ｂ［ｇ／ｍ２］とした場合、質量比率Ｂ／Ａが０．２０〜０．８０であることを特徴とする。 The pressure-sensitive adhesive body according to the present invention has a paper base material, a release sheet having a release layer provided on the paper base material, and an adhesive layer provided on the release layer, and the release layer is made of a silicone resin. The surface of the release sheet on which the release layer is provided has a smoothness of 2500 seconds or more, and the basis weight of the release layer is a basis weight A [g / m 2 ].

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。
本発明の一実施形態に係る剥離シートは、紙基材と、この紙基材上に設けられる剥離層とを備える。また、本発明の一実施形態に係る粘着体は、上記剥離シートと、剥離シートの剥離層の上に設けられた粘着シートとを備える。粘着シートは、基材シートと、この基材シートの少なくとも一方の面に粘着層が設けられたものであって、粘着層は粘着体において剥離層に密着している。ただし、粘着シートは、基材シートがないものであっても良い。粘着体は、特に限定されるわけではないが、例えばラベル加工された粘着シートがラベラー等によって被着体にラベリングされて使用されるものである。
Hereinafter, the present invention will be described in more detail using embodiments.
A release sheet according to an embodiment of the present invention includes a paper base material and a release layer provided on the paper base material. Moreover, the adhesive body which concerns on one Embodiment of this invention is equipped with the said peeling sheet and the adhesive sheet provided on the peeling layer of the peeling sheet. The pressure-sensitive adhesive sheet is a base sheet and a pressure-sensitive adhesive layer provided on at least one surface of the base sheet, and the pressure-sensitive adhesive layer is in close contact with the release layer in the pressure-sensitive adhesive body. However, the adhesive sheet may be one without a base sheet. The pressure-sensitive adhesive body is not particularly limited, but for example, a label-processed pressure-sensitive adhesive sheet is used by being labeled on an adherend by a labeler or the like.
本実施形態の剥離層は、紙基材の一方の面に剥離剤樹脂が塗工された後硬化されることにより形成されるものであって、剥離層の一部は紙基材に含浸されている。剥離層を形成するための剥離剤樹脂は、シリコーン樹脂が使用される。剥離剤樹脂は、例えばエマルション型、溶剤型、無溶剤型等の形態で、紙基材に塗布されるが、環境負荷等を低減させるために無溶剤型が好ましい。紙基材に塗布された剥離剤樹脂は、ラジカル重合型、縮合型、付加型、架橋型、又は開環重合型反応系などの硬化機構で硬化される。剥離剤樹脂としてはこれらの中でも、付加型反応系シリコーン樹脂が特に好ましい。付加型反応系シリコーン樹脂としては、１分子中に少なくとも２個のビニル基等のアルケニル基を有するオルガノポリシロキサン、１分子中に少なくとも２個のケイ素原子に結合した水素原子を有するオルガノポリシロキサンおよび白金系触媒を含み、所望により反応抑制剤等を含有するものが挙げられる。 The release layer of the present embodiment is formed by applying a release agent resin on one surface of a paper base material and then curing, and a part of the release layer is impregnated into the paper base material. ing. A silicone resin is used as the release agent resin for forming the release layer. The release agent resin is applied to the paper substrate in the form of, for example, an emulsion type, a solvent type, or a solvent-free type, but a solvent-free type is preferable in order to reduce environmental load and the like. The release agent resin applied to the paper substrate is cured by a curing mechanism such as a radical polymerization type, a condensation type, an addition type, a crosslinking type, or a ring-opening polymerization type reaction system. Among these, as the release agent resin, an addition-type reactive silicone resin is particularly preferable. Examples of the addition-type reactive silicone resin include organopolysiloxane having at least two alkenyl groups such as vinyl groups in one molecule, organopolysiloxane having at least two hydrogen atoms bonded to silicon atoms in one molecule, and Examples include those containing a platinum-based catalyst and optionally containing a reaction inhibitor and the like.
本実施形態では、剥離層を形成するために紙基材に塗工され硬化された剥離剤樹脂の坪量（すなわち、剥離層の坪量）を坪量Ａ［ｇ／ｍ２］とし、剥離層の剥離剤単体層の坪量を坪量Ｂ［ｇ／ｍ２］とした場合、剥離層に対する剥離剤単体層の質量比率Ｂ／Ａは０．２０〜０．８０とされる。なお、剥離剤単体層とは、剥離層のうち紙基材に含浸されていない部分のことをいう（後述する坪量Ｂの測定方法を参照）。 In this embodiment, the basis weight (that is, the basis weight of the release layer) of the release agent resin that has been applied to the paper substrate and cured to form the release layer is defined as the basis weight A [g / m 2 ]. When the basis weight of the release agent single layer of the layer is the basis weight B [g / m 2 ], the mass ratio B / A of the release agent single layer to the release layer is 0.20 to 0.80. In addition, a release agent simple substance layer means the part which is not impregnated in the paper base material among release layers (refer the measuring method of the basic weight B mentioned later).
質量比率Ｂ／Ａが０．２０より小さいと、紙基材表面が剥離層によって十分に覆われなくなり、剥離層表面に発生する凹凸やピンホールを十分に防止することができなくなる。したがって、剥離シートから粘着シートを剥離した場合に、剥離層上に残存する粘着剤の量（粘着剤残存量）、すなわち糊残り量を少なくすることが難しくなる。一方、質量比率Ｂ／Ａが０．８０より大きいと、紙基材に対する剥離層の密着力（投錨力）が不十分となって、粘着層上に剥離層の一部が転写するおそれがある。質量比率Ｂ／Ａは、糊残りや剥離層の粘着剤への転写をより効果的に防止するために、０．２５〜０．６０であることが好ましい。 When the mass ratio B / A is smaller than 0.20, the surface of the paper substrate is not sufficiently covered with the release layer, and unevenness and pinholes generated on the release layer surface cannot be sufficiently prevented. Therefore, when the pressure-sensitive adhesive sheet is peeled from the release sheet, it becomes difficult to reduce the amount of pressure-sensitive adhesive remaining on the release layer (pressure-sensitive adhesive remaining amount), that is, the amount of adhesive remaining. On the other hand, if the mass ratio B / A is larger than 0.80, the adhesion (peeling force) of the release layer to the paper substrate becomes insufficient, and a part of the release layer may be transferred onto the adhesive layer. . The mass ratio B / A is preferably 0.25 to 0.60 in order to more effectively prevent adhesive residue and transfer of the release layer to the adhesive.
また、剥離シートの剥離層が設けられた側の面を、平滑度２５００秒以上とするとともに、質量比率Ｂ／Ａを０．２０〜０．８０とすることにより、粘着シートを剥離シートから高速剥離した場合でも、剥離シートの剥離力を適切な値に維持することができる。そのため、ラベル抜き加工とカス取りを３０ｍ／分程度の速度で行ってもラベルがカスとともに一緒に除去されてしまう身上がりが発生することはない。また、ラベリングを高速（例えば、１００ｍ／分以上）で行っても、剥離不良が発生することもない。 In addition, the surface of the release sheet on which the release layer is provided has a smoothness of 2500 seconds or more, and the mass ratio B / A is 0.20 to 0.80. Even when peeled, the peel force of the release sheet can be maintained at an appropriate value. For this reason, even if the label removal process and the scrap removal are performed at a speed of about 30 m / min, the label is not removed together with the scraps. Moreover, even if the labeling is performed at a high speed (for example, 100 m / min or more), no peeling failure occurs.
剥離層を形成するために紙基材に塗工され硬化された剥離剤樹脂の坪量Ａは、０．３０〜３．００ｇ／ｍ２であることが好ましく、０．５０〜２．５０ｇ／ｍ２であることがより好ましい。また、剥離剤単体層の坪量Ｂは、０．１０〜２．４０ｇ／ｍ２であることが好ましく、０．２０〜２．００ｇ／ｍ２であることがより好ましい。剥離剤は、例えばグラビアコーター、ロッドコーター、又はエアードクターコーターなどの公知の方法で紙基材に塗工される。 The basis weight A of the release resin applied and cured on the paper base material to form the release layer is preferably 0.30 to 3.00 g / m 2 , and is preferably 0.50 to 2.50 g / m 2. more preferably m 2. The basis weight B of the release agent alone layer is preferably 0.10~2.40g / m 2, and more preferably 0.20~2.00g / m 2. The release agent is applied to the paper substrate by a known method such as a gravure coater, a rod coater, or an air doctor coater.
紙基材は、原紙と、原紙の一面又は両面に設けられた目止め層とを有し、剥離層が紙基材の目止め層が設けられた側の面に設けられるものであることが好ましい。 The paper base has a base paper and a sealing layer provided on one or both sides of the base paper, and the release layer is provided on the side of the paper base on which the sealing layer is provided. preferable.
紙基材の少なくとも剥離層が設けられる側の面は、平滑度１０００秒以上、透気度３１，０００秒以上とされている。また、剥離シートの剥離層が設けられた側の面は、剥離層が設けられることによってその平滑度が高められ、平滑度２５００秒以上となる。 At least the surface of the paper substrate on which the release layer is provided has a smoothness of 1000 seconds or more and an air permeability of 31,000 seconds or more. Further, the smoothness of the surface of the release sheet on which the release layer is provided is increased by providing the release layer, and the smoothness becomes 2500 seconds or more.
紙基材の平滑度及び透気度がこのように高い値に設定されると、紙基材への剥離剤樹脂の浸み込み量が制御され、質量比率Ａ／Ｂが０．２０〜０．８０に調整されやすくなる。また、剥離シートの剥離層が設けられた側の面の平滑度が２５００秒以上であるため、剥離層表面におけるピンホールや凹凸が低減され、粘着シートを剥離シートから剥離した際の糊残りを低減させやすくなる。 When the smoothness and air permeability of the paper base material are set to such high values, the amount of the release agent resin penetrated into the paper base material is controlled, and the mass ratio A / B is 0.20 to 0. .80 is easily adjusted. Moreover, since the smoothness of the surface of the release sheet on which the release layer is provided is 2500 seconds or more, pinholes and irregularities on the release layer surface are reduced, and the adhesive residue when the adhesive sheet is released from the release sheet is reduced. It becomes easy to reduce.
糊残りをより効果的に低減させるために、紙基材の少なくとも剥離層が設けられる側の面は、平滑度が１６００秒以上であることが好ましく、また、透気度は１００，０００秒以上であることが好ましい。さらに、剥離シートの剥離層が設けられた側の面の平滑度は、４０００秒以上であることが好ましい。 In order to reduce the adhesive residue more effectively, at least the surface of the paper base on which the release layer is provided preferably has a smoothness of 1600 seconds or more, and an air permeability of 100,000 seconds or more. It is preferable that Furthermore, the smoothness of the surface of the release sheet on which the release layer is provided is preferably 4000 seconds or more.
原紙としては、特に限定されるものではなく、剥離シートに一般的に用いられるものが使用され、例えば上質紙、再生紙、クラフト紙、ロール紙、グラシン紙などが好適に使用される。また、原紙は、セルロース繊維を主成分とする限りは、他の繊維例えばポリエチレン、ポリプロピレン、ポリエステルなどの繊維が少量含有されていても良い。原紙に使用されるパルプとしては、Ｎ−ＢＫＰ（針葉樹晒硫酸塩パルプ）、Ｎ−ＢＳＰ（針葉樹晒亜硫酸パルプ）、Ｌ−ＢＫＰ（広葉樹晒硫酸塩パルプ）、又はＬ−ＢＳＰ（広葉樹晒亜硫酸パルプ）等が例示される。 The base paper is not particularly limited, and those generally used for release sheets are used. For example, high-quality paper, recycled paper, craft paper, roll paper, glassine paper and the like are preferably used. In addition, the base paper may contain a small amount of other fibers such as polyethylene, polypropylene, and polyester as long as the cellulose fiber is the main component. The pulp used for the base paper is N-BKP (softwood bleached sulfite pulp), N-BSP (softwood bleached sulfite pulp), L-BKP (hardwood bleached sulfate pulp), or L-BSP (hardwood bleached sulfite pulp). And the like.
原紙の坪量は、特に限定されるものではないが、好ましくは２０〜２５０ｇ／ｍ２、より好ましくは３０〜１５０ｇ／ｍ２である。坪量が２０ｇ／ｍ２未満になると紙の強度が低下し、剥離剤の塗工工程において作業性が劣ることがあり、２５０ｇ／ｍ２を超えるとコストが高くなる。 Although the basic weight of a base paper is not specifically limited, Preferably it is 20-250 g / m < 2 >, More preferably, it is 30-150 g / m < 2 >. When the basis weight is less than 20 g / m 2, the strength of the paper is lowered, and the workability may be deteriorated in the coating process of the release agent, and when it exceeds 250 g / m 2 , the cost is increased.
目止め層としては、従来公知の水溶性樹脂等の塗料が塗工されて形成されたものが使用される。目止め層用の塗料としては、デンプンやポリビニルアルコール等のバインダー、所望により添加されるサイズ剤、着色剤、流動性調整剤、消泡剤等の添加剤、及び溶媒等を含む塗料等が使用される。塗料は、例えばエアードクターコーター、サイズプレスコーター、ゲートロールコーター、ナイフコーター、又はリバースコーターなどの公知の方法によって原紙に塗工される。これらの中でも、目止め層を原紙両面に設けることができるオンマシン（すなわち、抄紙中）でのサイズプレスコーターが、生産性や品質安定性を高めることができるため好ましい。 As the sealing layer, a layer formed by applying a paint such as a conventionally known water-soluble resin is used. As the coating material for the sealing layer, a coating material containing a binder such as starch or polyvinyl alcohol, an additive such as a sizing agent, a coloring agent, a fluidity adjusting agent, an antifoaming agent, or the like, and a solvent as required. Is done. The paint is applied to the base paper by a known method such as an air doctor coater, a size press coater, a gate roll coater, a knife coater, or a reverse coater. Among these, an on-machine (that is, in papermaking) size press coater in which a sealing layer can be provided on both sides of the base paper is preferable because productivity and quality stability can be improved.
目止め層が両面に設けられる場合、目止め層を形成する塗料の塗工量（固形分）の両面合計は、特に限定されないが、目止め性能を効果的に発揮させ、かつ剥離剤樹脂の浸み込みを適度に抑えるために、好ましくは１〜１０ｇ／ｍ２、より好ましくは２．１〜５．０ｇ／ｍ２とされる。すなわち、片面あたりの塗料の塗工量（固形分）は、好ましくは０．５〜５ｇ／ｍ２、より好ましくは１．０５〜２．５ｇ／ｍ２とされる。 When the sealing layer is provided on both surfaces, the total amount of both sides of the coating amount (solid content) of the coating material forming the sealing layer is not particularly limited. In order to moderate penetration, it is preferably 1 to 10 g / m 2 , more preferably 2.1 to 5.0 g / m 2 . That is, the coating amount (solid content) of the paint per side is preferably 0.5 to 5 g / m 2 , more preferably 1.05 to 2.5 g / m 2 .
紙基材の平滑度及び透気度を調整するために、原紙にスーパーカレンダー処理が施されることが好ましく、またダンピングマシン等によって原紙の水分が適宜調整されることが好ましい。 In order to adjust the smoothness and air permeability of the paper base material, it is preferable that the base paper is subjected to a super calender treatment, and the moisture of the base paper is preferably adjusted as appropriate by a damping machine or the like.
粘着シートの基材シートとしては、紙類、プラスチックシート等が使用される。粘着層を形成するための粘着剤としては、アクリル系粘着剤、ウレタン系粘着剤、ゴム系粘着剤等が使用され、これらの中でもアクリル系粘着剤が特に好ましい。また、粘着剤の塗工液は、エマルション型、溶剤型、無溶剤型の形態のいずれでも良い。 As the base sheet of the pressure-sensitive adhesive sheet, papers, plastic sheets and the like are used. As the pressure-sensitive adhesive for forming the pressure-sensitive adhesive layer, acrylic pressure-sensitive adhesives, urethane pressure-sensitive adhesives, rubber-based pressure-sensitive adhesives, and the like are used, and among these, acrylic pressure-sensitive adhesives are particularly preferable. Further, the pressure-sensitive adhesive coating solution may be any of an emulsion type, a solvent type, and a solventless type.
以上のように本実施形態では、剥離層に対する剥離剤単体層の質量比率Ｂ／Ａが０．２０以上とされることにより、紙基材表面が剥離層によって十分に覆われることになる。これにより、剥離層表面の平滑度が高い（２５００秒以上）ことと相俟って、剥離シートの剥離層が設けられた側の面に、凹凸やピンホールができにくくなり、粘着シートを剥離シートから剥離した際、糊残りが発生しにくくなる。そのため、例えば、ラベル加工された粘着シートをラベリングする場合に、ラベラーのガイドローラ等に粘着剤が付着することが防止され、ラベリングの作業性を良好なものに維持することができる。また、剥離層に無溶剤型、粘着層にエマルション型のものが使用されるような場合でも、糊残りを十分に低減させることが可能である。 As described above, in this embodiment, when the mass ratio B / A of the release agent single layer to the release layer is 0.20 or more, the paper substrate surface is sufficiently covered with the release layer. As a result, coupled with the high smoothness of the release layer surface (2500 seconds or more), it becomes difficult to form irregularities and pinholes on the surface of the release sheet on which the release layer is provided, and the adhesive sheet is peeled off. When peeled from the sheet, adhesive residue is less likely to occur. Therefore, for example, when labeling a pressure-sensitive adhesive sheet that has been subjected to labeling, it is possible to prevent the adhesive from adhering to a guide roller or the like of the labeler, and to maintain good labeling workability. Further, even when a solvent-free type is used for the release layer and an emulsion type is used for the adhesive layer, the adhesive residue can be sufficiently reduced.
なお、本明細書において、平滑度はＪＩＳ Ｐ ８１１９：１９９８に準じて測定したもの、透気度はＪＡＰＡＮ ＴＡＰＰＩ ＮＯ．５−２：２０００に準じて測定したもの、紙の坪量はＪＩＳ Ｐ８１２４：１９８８に準じて測定したものである。また、叩解度は、ＪＩＳ Ｐ ８１２１：１９９５． パルプのろ水度試験方法に準拠して、ショッパー・リグラー形叩解度試験機により測定したものである。 In the present specification, the smoothness is measured according to JIS P 8119: 1998, and the air permeability is determined by JAPAN TAPPI NO. The basis weight of the paper measured according to 5-2: 2000 was measured according to JIS P8124: 1988. The beating degree is JIS P 8121: 1995. It was measured by a shopper-regler type beating degree tester in accordance with the freeness test method for pulp.
また、剥離層を形成するために紙基材に塗工されて硬化された剥離剤樹脂（すなわち、剥離層）の坪量Ａ［ｇ／ｍ２］は、剥離剤樹脂の塗工量（固形分）であって、剥離層面の蛍光Ｘ線測定により、単位面積当たりのケイ素の存在量を基にして求められるものである。一方、剥離剤単体層の坪量Ｂは、以下のように求めたものである。まず剥離層の剥離剤単体層の厚みを、Ｘ線光電子分光分析法を用いて測定する。具体的には、先ず、アルゴンビームで剥離層面を３０秒間スパッタ掘削した後、Ｘ線光電子分光分析法にて、剥離層面の構成原子中のケイ素濃度を測定し、これをケイ素濃度の初期値とする。次いで、ケイ素濃度の初期値の測定で掘削した領域と同じ領域をさらに一定時間スパッタ掘削し、Ｘ線光電子分光分析法にて、掘削された剥離層面の構成原子中のケイ素濃度を測定する。これを繰り返し行い、剥離層の各深さでのケイ素濃度を測定する。なお、剥離層の掘削された深さは、単位時間当たりのスパッタ掘削厚みを基にして算出できる。
ここで、剥離層の深さ方向のケイ素濃度が、初期値の９０％以上のケイ素濃度が検出される剥離層の深さを剥離剤単体層の厚みとする。上記範囲以外の部分は、剥離剤樹脂が紙基材に含浸されているかまたは剥離剤樹脂が存在しない部分となる。得られた剥離層の深さ方向のケイ素濃度のデータより、初期値の９０％以上のケイ素濃度が検出される剥離層の厚みを、単位時間当たりの掘削厚みから算出し、剥離剤単体層の厚みを求め、３回の測定による平均値で評価する。なお、ケイ素濃度の初期値が、剥離層に使用した剥離剤樹脂のケイ素濃度と同一であることを予め確認しておくとよい。剥離剤単体層の厚みと剥離剤樹脂の比重から、下記式（１）より坪量Ｂを算出する。そして、坪量Ｂ／坪量Ａを、剥離層に対する剥離剤単体層の質量比率Ｂ／Ａとする。
坪量Ｂ＝剥離剤単体層の厚み×剥離剤樹脂の比重・・・（１）
Further, the basis weight A [g / m 2 ] of the release agent resin (that is, the release layer) applied to the paper base material and cured to form the release layer is the coating amount (solid) of the release agent resin. And is determined based on the amount of silicon present per unit area by fluorescent X-ray measurement on the surface of the release layer. On the other hand, the basis weight B of the release agent single layer is determined as follows. First, the thickness of the release agent single layer of the release layer is measured using X-ray photoelectron spectroscopy. Specifically, first, the release layer surface was sputtered for 30 seconds with an argon beam, and then the silicon concentration in the constituent atoms of the release layer surface was measured by X-ray photoelectron spectroscopy, and this was determined as the initial value of the silicon concentration. To do. Subsequently, the same region as the region excavated by measurement of the initial value of the silicon concentration is further sputter excavated for a certain time, and the silicon concentration in the constituent atoms of the excavated release layer surface is measured by X-ray photoelectron spectroscopy. This is repeated and the silicon concentration at each depth of the release layer is measured. The excavated depth of the release layer can be calculated based on the sputter excavation thickness per unit time.
Here, the depth of the release layer at which the silicon concentration in the depth direction of the release layer is detected to be 90% or more of the initial value is defined as the thickness of the release agent single layer. The part other than the above range is a part where the release agent resin is impregnated in the paper substrate or the release agent resin is not present. From the obtained silicon concentration data in the depth direction of the release layer, the thickness of the release layer in which a silicon concentration of 90% or more of the initial value is detected is calculated from the excavation thickness per unit time, and the release agent single layer The thickness is obtained and evaluated by an average value obtained by three measurements. In addition, it is good to confirm beforehand that the initial value of the silicon concentration is the same as the silicon concentration of the release agent resin used for the release layer. From the thickness of the release agent single layer and the specific gravity of the release agent resin, the basis weight B is calculated from the following formula (1). The basis weight B / basis weight A is defined as the mass ratio B / A of the release agent single layer to the release layer.
Basis weight B = thickness of release agent single layer × specific gravity of release agent resin (1)
