Zusammenfassung:	To provide a process peeling sheet for manufacturing synthetic leather with excellent heat-resistant durability and with extremely less changes in a surface texture even when a resin sheet is repeatedly used in a step of peeling a resin layer from a process peeling sheet after the resin layer is formed by coating a surface of the process peeling sheet with a resin liquid in the process peeling sheet.SOLUTION: A process peeling sheet for manufacturing synthetic leather is formed by sequentially laminating a filling layer whose main components are granular powder and a binder and a release agent layer on a paper support. Change in glossiness after 10-minute processing under 200°C is less than 5.SELECTED DRAWING: None 【課題】合成皮革製造用の工程剥離シートにおいて、工程剥離シート表面に熱溶融した樹脂液を塗工して樹脂層を形成した後、該樹脂層を工程剥離シートから剥離する工程に繰り返し使用しても表面性状の変化が極めて少ない、耐熱耐久性に優れた工程剥離シートを提供する。【解決手段】紙製支持体の上に粒状粉体及びバインダーを主成分とした目止め層、及び剥離剤層を順次積層してなる合成皮革製造用工程剥離シートであって、２００℃環境下に、１０分間処理後の光沢度の変化が５未満である合成皮革製造用工程剥離シート。【選択図】なし
