Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a protective film for glass protection.SOLUTION: In a method for manufacturing a protective film 340, 440 comprising an adhesive layer 341, 441 and a non-adhesive layer 345, 445 laminated together, the non-adhesive layer is obtained by the steps of: a) producing fine particles 345b, 445b by a polymerization process; b) mixing the fine particles with a synthetic resin 345a, 445a; and c) forming a mixture of the fine particles and the synthetic resin into a layer. The protective film comprises: a non-adhesive layer including a first synthetic resin, and fine particles of a polymer dispersed in the first synthetic resin; and an adhesive layer including a second synthetic resin laminated together. 【課題】ガラス保護用保護フィルムを提供する。【解決手段】本発明は、粘着層３４１、４４１と非粘着層３４５、４４５とが積層されてなる保護フィルム３４０、４４０を製造するための方法であって、前記非粘着層は、ａ）重合工程によって微細粒子３４５ｂ、４４５ｂを製造する段階と、ｂ）前記微細粒子を合成樹脂３４５ａ、４４５ａと混合する段階と、ｃ）前記微細粒子と前記合成樹脂との混合物を層状に成形する段階とから得られることを特徴とする保護フィルムの製造方法を提供する。また、本発明は、第１の合成樹脂と前記第１の合成樹脂中に分散され重合体である微細粒子とを含む非粘着層と、第２の合成樹脂を含む粘着層とが積層されてなる保護フィルムを提供する。【選択図】図７
