The present invention relates to a multilayer film for fiber bonding and/or fiber sheet surface protection, which is obtained by laminating a layer (I) that is formed from a thermosetting composition (i) on a support film (II), and wherein the thermosetting composition (i) contains a thermal polymerization initiator (C) that has a 10-hour half-life temperature of 65°C or higher. La présente invention concerne un film multicouche permettant la liaison de fibres et/ou la protection de surface de feuille de fibres, qui est obtenu par stratification d'une couche (I) formée à partir d'une composition thermodurcissable (i) sur un film de support (II), la composition thermodurcissable (i) contenant un initiateur de polymérisation thermique (C) qui a une température de demi-vie de 10 heures de 65 °C ou plus. 本発明は、熱硬化性組成物［ｉ］からなる層［Ｉ］と、支持フィルム［ＩＩ］とが積層されてなる繊維接着及び／又は繊維シート表面保護用積層フィルムであって、熱硬化性組成物［ｉ］が、１０時間半減期温度が６５℃以上の熱重合開始剤（Ｃ）を含有する、繊維接着及び／又は繊維シート表面保護用積層フィルムに関する。
