| description | Provided is a surface protection film for a prism sheet, which can be spread from a roll with a small force, and the tacky adherence force of which is not easily lowered by the release layer adhering to the pressure-sensitive adhesive layer. The surface protection film is a laminated film composed of (A) a release layer which consists mainly of a saturated fatty acid bisamide and has a thickness of 1 to 100nm, (B) a substrate layer consisting of a polyolefin resin, and (C) a pressure-sensitive adhesive layer consisting of a styrene-based elastomer, said laminated film being produced by co-extruding a molding material (A) which comprises the saturated fatty acid bisamide and the polyolefin resin and another molding material (B) which comprises the styrene-based elastomer. |
