PROBLEM TO BE SOLVED: To provide a release film for a pasting agent, even if a release film for a pasting agent is dropped when a percutaneous absorption pasting agent is used, having high visibility and easy to be picked up, and in which pasting operability when a percutaneous absorption pasting agent is used is not inferior with the conventional release film for a pasting agent, cost is inexpensive, and waste when the release film is disposed of can be volume-reduced.SOLUTION: There is provided a release film for a pasting agent, in which one surface of a base material film 1 is subjected to release treatment to laminate a release agent layer 2, in at least one edge part or the whole surface of the surface on the side opposite to the base material film 1, a patterned resin coat layer 3 is formed by applying a resin composition containing (A) one or more resins selected from a polyester resin, an acrylic resin, a polyurethane resin, an epoxy resin, a phenol resin, a silicone resin, and nitrocellulose ( cellulose nitrate), and (B) one or more selected from a pigment, a dye, a coloring matter, a metal fine particle, a metal oxide particle, a resin fine particle, a fine particle of a natural mineral, a carbon black and glass beads.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】経皮吸収貼布剤を使用する時に、貼布剤用離型フィルムを落とした場合であっても、視認性が良く、拾い上げ易く、かつ、経皮吸収貼布剤を使用する時の貼付操作性も従来と遜色なく、コスト的に安価であり、廃棄した際の廃棄物を減容できる貼布剤用離型フィルムを提供する。【解決手段】基材フィルム1の片面に離型処理が施され、離型剤層2が積層されており、基材フィルム1の反対側の面の、少なくとも1カ所の縁部に、または全面に、パターン化した樹脂コート層3が、(A)ポリエステル樹脂、アクリル樹脂、ポリウレタン樹脂、エポキシ樹脂、フェノール樹脂、シリコーン樹脂、ニトロセルロース(硝化綿)から選択された1種以上の樹脂と、(B)顔料、染料、色素、金属微粒子、金属酸化物粒子、樹脂微粒子、天然鉱物の微粒子、カーボンブラック、ガラスビーズから選択された1種以上と、を含有する樹脂組成物を塗布して形成されてなる。【選択図】図1
