A flexible antifouling and noncombustible film material (Patent Document 2) comprising an intermediate layer made of It was 討. Although the film materials of Patent Documents 1 and 2 are certainly a flexible film material having both noncombustibility and antifouling properties, the film material has a non-combustible fiber (for example, glass fiber) adhesive property between the fabric and the silicone elastomer composition. Inferior, light transmission damage of whitening scars when film material is strongly bent (whitening scratches caused by a change in the refractive index due to the fine separation of the silicone elastomer from the fiber surface and the replacement of the separated fines with air) It has recently become clear that the silicone elastomer layer is liable to peel off and fall off when the film material is repeatedly bent, and improvement thereof is desired.
