Description
本発明は、薬効成分を有する粘着薬剤からなる層が支持体層によって支持されてなる貼付剤の粘着薬剤表面を保護するための離型フィルムに関し、特にプラスチックフィルムの両面に貼付剤を粘着させる貼付剤用両面離型フィルムに関する。 The present invention relates to a release film for protecting the adhesive agent surface of an adhesive patch in which a layer made of an adhesive agent having a medicinal component is supported by a support layer, and in particular, an adhesive for adhering the adhesive agent to both surfaces of a plastic film. The present invention relates to a double-sided release film for agents.
編織布または不織布などの通気性と柔軟性とを有する素材からなる支持体層の片面に経皮消炎鎮痛剤や湿布剤（温湿布や冷湿布）などの薬効成分を含む粘着性組成物からなる粘着性薬剤層を設けた貼付剤は、家庭薬なども含め広く用いられている。 It consists of an adhesive composition containing medicinal ingredients such as transdermal anti-inflammatory analgesics and poultices (hot and cold compresses) on one side of a support layer made of a material having air permeability and flexibility such as a woven or non-woven fabric. Patches with an adhesive drug layer are widely used, including home remedies.
これら貼付剤は、使用直前までその粘着性薬剤層側表面は離型紙あるいは離型フィルムで保護されていて、使用時にこれらから剥がされて用いられる（特開２００１−２４５９１８公報（特許文献１）、特開２００１−２５８９２６公報（特許文献２）、特開平８−１１２３０５公報（特許文献３）参照）。ここで、現在では透明な離型フィルムの方が離型紙に比べて「清潔感」「クリーンさ」の点で好印象を与えるので、より多く、透明な離型フィルムが使われるようになっている。このような離型紙、離型フィルムは、貼付剤を剥がした後、床に落としてしまう場合がある。 The adhesive drug layer side surface of these patches is protected with a release paper or a release film until just before use, and is peeled off from these during use (Japanese Patent Laid-Open No. 2001-245918 (Patent Document 1)). JP 2001-258926 A (Patent Document 2), JP 8-112305 A (Patent Document 3)). Now, since transparent release films give a better impression in terms of “cleanliness” and “cleanness” than release paper, more transparent release films are now being used. Yes. Such release paper and release film may fall on the floor after the patch is peeled off.
このとき、透明な離型フィルムは見つけにくく、さらに、その離型面はシリコーン処理によりすべり性が高いので、そのまま放置された場合には人が踏みつけて転びやすく、さらに病院などでは松葉杖利用者が、この離型フィルムの上に松葉杖を突いて事故が発生するなど多くの問題が生じる。そこで、離型フィルムは離型面とはしない面に印刷を施し、視認性を向上させているのが一般的である。
しかしながら、比較的小型の貼付剤の場合には、２枚の貼付剤を両面離型フィルムを挟んで貼り合わせた形状で供給されることが多い。このような両面離型フィルムは、一般に、透明なプラスチックフィルムの両面にシリコーン類を塗布して離型層を形成して作製される。このため、プラスチックフィルムの離型層を形成しない面に印刷を施すと云う通常の手段を採ることができない。 However, in the case of a relatively small patch, it is often supplied in a shape in which two patches are bonded with a double-sided release film sandwiched therebetween. Such a double-sided release film is generally produced by applying a silicone to both sides of a transparent plastic film to form a release layer. For this reason, the usual means of printing on the surface of the plastic film where the release layer is not formed cannot be taken.
ここで、離型層上に印刷しようとしてもインクがはじかれてしまうので印刷できない。一方、印刷面の上に離型層を設けた場合には印刷がにじみ不鮮明となり、その結果、使用者の商品に対する印象が悪化するおそれがある。また、印刷層の上に保護層を設け、その保護層の上に離型層を設けることによりこれら問題を解決することは可能となるが両面離型フィルムとしての価格が高くなり、実用的でなくなると云う別の問題が生じる。 Here, even if it is going to print on a mold release layer, since ink will be repelled, it cannot print. On the other hand, when the release layer is provided on the printing surface, the printing is blurred and unclear, and as a result, the user's impression of the product may be deteriorated. In addition, it is possible to solve these problems by providing a protective layer on the printing layer and providing a release layer on the protective layer, but the price as a double-sided release film is increased and practical. Another problem is that it will disappear.
本発明は、これら問題点を改善する、すなわち、実用的で、視認性に優れ、「清潔感」「クリーンさ」のイメージを損なうことのない貼付剤用両面離型フィルムを提供することを目的とする。 The present invention aims to improve these problems, that is, to provide a double-sided release film for a patch that is practical, excellent in visibility, and does not impair the image of “clean feeling” and “cleanness”. And
本発明の貼付剤用両面離型フィルムは上記課題を解決するため、請求項１に記載の通り、透明なプラスチックフィルムの両面に離型層が設けられた貼付剤用両面離型フィルムであって、少なくとも一方の離型層が顔料または／及び染料を有している貼付剤用両面離型フィルムである。 In order to solve the above problems, the double-sided release film for a patch of the present invention is a double-sided release film for a patch in which a release layer is provided on both sides of a transparent plastic film as described in claim 1. , A double-sided release film for patches, in which at least one release layer has a pigment or / and a dye.
本発明の貼付剤用両面離型フィルムはその特有の構成により、低コストでの生産が可能であり、床に落ちたときにも容易に発見でき、思いがけない事故の原因となることが予防される。 Due to its unique structure, the double-sided release film for patch of the present invention can be produced at low cost, can be easily detected even when it falls on the floor, and can prevent unexpected accidents. The
本発明における透明なプラスチックフィルムとしては、離型フィルムとして取り扱い可能であれば、厚さ、材質に制限がなく、特に厚さは一般にシートとして分類されるような厚さのものであっても良い。なお、「清潔感」「クリーンさ」のイメージに直結するため、不透明や半透明などのものではなく、透明なものであることが必要である。 The transparent plastic film in the present invention is not limited in thickness and material as long as it can be handled as a release film. In particular, the thickness may be a thickness that is generally classified as a sheet. . In addition, in order to be directly connected to the image of “clean feeling” and “cleanness”, it is necessary to be transparent rather than opaque or translucent.
本発明の貼付剤用両面離型フィルムは、両面離型である必要があるため、離型層はプラスチックフィルムの両面に設ける必要がある。この離型層は原則、従来からの貼付剤用両面離型フィルムの形成方法、一般的にはシリコーン系離型剤塗布による。ただし、この際、少なくとも１層の離型層に顔料または／及び染料を配する。すなわち、塗布前のシリコーン系離型剤に顔料または／及び染料を、混練などの方法で混合し、得られた着色したシリコーン系離型剤を用いて、離型層を形成する。なお、用いる顔料、染料は、医薬的に用い得るものから選択する必要があり、さらに、その離型剤への添加濃度は最終的に得られる貼付剤用両面離型フィルムで充分な着色効果が得られる範囲である必要がある。 Since the double-sided release film for a patch of the present invention needs to be double-sided, it is necessary to provide release layers on both sides of the plastic film. In principle, the release layer is formed by a conventional method for forming a double-sided release film for a patch, and generally a silicone release agent. However, at this time, a pigment or / and a dye are arranged in at least one release layer. That is, a pigment or / and a dye are mixed with a silicone release agent before coating by a method such as kneading, and a release layer is formed using the obtained colored silicone release agent. In addition, it is necessary to select the pigment and the dye to be used from those that can be used pharmaceutically. Furthermore, the concentration added to the release agent is such that a double-sided release film for a patch that is finally obtained has a sufficient coloring effect. It must be within the range obtained.
本発明の貼付剤用両面離型フィルムの構成を、イメージ断面図を用いて説明する。図１には３種類（実質２種類）の本発明に係る貼付剤用両面離型フィルムのモデル断面図を示した。図１（ａ）には上面の離型層にのみ染料が添加された両面離型フィルムａを、図１（ｂ）には下面の離型層にのみ染料が添加された両面離型フィルムａ’（両面離型フィルムａの上下が逆になったもの）を、図１（ｃ）には両方の離型層に染料が添加された両面離型フィルムｂを、それぞれ示す。 The structure of the double-sided release film for a patch of the present invention will be described using an image sectional view. FIG. 1 shows model cross-sectional views of the double-sided release film for patch according to the present invention of three types (substantially two types). FIG. 1 (a) shows a double-sided release film a in which a dye is added only to the upper release layer, and FIG. 1 (b) shows a double-sided release film a in which a dye is added only to the lower release layer. FIG. 1 (c) shows a double-sided release film b in which a dye has been added to both release layers.
このような両面離型フィルムは図２にモデル的に示すようにして用いられる。すなわち、図２は粘着薬剤層と支持体層とを有する貼付剤２つを互いの粘着剤層同士が内側になるようにして、上記貼付剤用両面離型フィルムａを挟んで貼り合わせた状態を示す図である。 Such a double-sided release film is used as schematically shown in FIG. That is, FIG. 2 shows a state in which two adhesives each having an adhesive drug layer and a support layer are bonded together with the adhesive layer between each other, with the adhesive layers facing each other. FIG.
なお、図２の例では両面離型フィルムａは貼付剤の引きはがしが容易であるように貼付剤より大きいものを用いている。また、図２では粘着薬剤層と支持体層とからなる貼付剤での例を示したが、粘着剤層と支持体層との間に両者の密着性を向上させるためのアンカーコート層を設けた貼付剤を用いても良い。 In the example of FIG. 2, the double-sided release film a is larger than the patch so that the patch can be easily peeled off. Moreover, although the example in the patch which consists of an adhesive chemical | medical agent layer and a support body layer was shown in FIG. 2, the anchor coat layer for improving both adhesiveness is provided between an adhesive layer and a support body layer. An adhesive patch may be used.
以下に本発明の貼付剤用両面離型フィルムの実施例について具体的に説明する。 Examples of the double-sided release film for patch of the present invention will be specifically described below.
厚さ５０μｍの透明な２軸延伸ポリエチレンテレフタレートフィルムの片側に、シリコーン系離型剤１．２重量％、フタロシアニン系青色顔料０．２重量％、溶媒としてメチルエチルケトン７０重量％、トルエン２８重量％からなる離型層コート剤を乾燥重量が１．０ｇ／ｍ2となるようにグラビアロール法で塗布、乾燥、熱処理を行い、顔料を有する離型層を設け、さらに反対の面に同様の方法で乾燥重量が１．０ｇ／ｍ2の顔料を有する離型層を設け、顔料が配された離型層を２面有する、本発明に係る両面離型フィルムｃを得た。 On one side of a transparent biaxially stretched polyethylene terephthalate film having a thickness of 50 μm, 1.2% by weight of a silicone release agent, 0.2% by weight of a phthalocyanine blue pigment, 70% by weight of methyl ethyl ketone as a solvent, and 28% by weight of toluene The release layer coating agent is applied by a gravure roll method so that the dry weight becomes 1.0 g / m 2 , dried and heat-treated, provided with a release layer having a pigment, and further dried on the opposite side by the same method. A release layer having a weight of 1.0 g / m 2 was provided, and a double-sided release film c according to the present invention having two release layers provided with the pigment was obtained.
この本発明に係る両面離型フィルムｃの着色は、視認観察の結果、全面に亘って均一な青色半透明であることが確認された。また、この両面離型フィルムｃはフタロシアニン系青色顔料を用いずに作製した従来技術に係る両面離型フィルムｄと同等の、貼付剤に対する離型性が得られ、全く同様の取り扱い性であったが、白いタイルの床やクリーム色のビニールタイルの床などに落とした際には非常に見つけやすかった。 As a result of visual observation, the coloration of the double-sided release film c according to the present invention was confirmed to be uniform blue translucent over the entire surface. Further, this double-sided release film c had the same releasability as the double-sided release film d according to the prior art prepared without using a phthalocyanine-based blue pigment, and had exactly the same handleability. However, it was very easy to find when dropped on a white tile floor or creamy vinyl tile floor.
また、厚さ５０μｍの透明な２軸延伸ポリエチレンテレフタレートフィルムの片側にフタロシアニン系青色インキにてグラビァロール法により全面印刷を施した後、他方の面に上記実施例で用いたのと同様の、ただしフタロシアニン系青色顔料が添加されていない離型層コート剤で顔料を有しない離型層を形成し、さらに印刷面の上にも同様に顔料を有しない離型層を形成し、比較例に係る両面離型フィルムｅを得た。 Further, after printing on the entire surface by a gravure roll method with a phthalocyanine-based blue ink on one side of a transparent biaxially stretched polyethylene terephthalate film having a thickness of 50 μm, the same as that used in the above examples on the other side, except for the phthalocyanine A release layer having no pigment is formed with a release layer coating agent to which no system blue pigment is added, and a release layer having no pigment is similarly formed on the printed surface. A release film e was obtained.
この両面離型フィルムｅの着色は視認観察の結果、青色半透明であったが、幅方向、長さ方向で色調が大きく変動しており、全体に流れスジが見られ、商品価値のないものであった。また、面の違いによる貼付剤の離型性が大きく異なり、印刷層の上に施された剥離面での必要な剥離力は印刷層のない面に施された剥離面で必要な剥離力の４倍ないし８倍と極めて大きく、そのため極めて取り扱いにくいと云う結果が得られた。 As a result of visual observation, the coloring of this double-sided release film e was blue translucent, but the color tone greatly fluctuated in the width direction and the length direction. Met. In addition, the releasability of the patch varies greatly depending on the surface, and the required peel force on the peel surface applied on the printed layer is the same as that required on the peel surface applied on the surface without the print layer. The result was that it was extremely large, 4 to 8 times, and therefore very difficult to handle.
本発明の貼付剤用両面離型フィルムは、実用的で、視認性に優れ、「清潔感」「クリーンさ」のイメージを損なうことのない貼付剤用両面離型フィルムである。 The double-sided release film for patches of the present invention is a double-sided release film for patches that is practical, excellent in visibility, and does not impair the image of “clean feeling” and “cleanness”.
