PROBLEM TO BE SOLVED: To provide a laminated film useful for manufacturing a surface protective film having transparency, hardly charged at the time of friction or peeling, having a surface hard to generate the adhesion of a stain, provided with an improved pressure-sensitive adhesive layer easily peeled from a pasted surface to be protected regardless of the elapse of time and not damaging the examination properties of the pasted surface to be protected. SOLUTION: The laminated film used in the production of the surface protective film is constituted by providing a film, which contains a composition comprising 40 to 85 wt.% of an acrylic copolymer (A) with a glass transition temperature of -10 to 50 deg.C, 10 to 50 wt.% of an antistatic agent (B) obtained by polymerizing thiophene or a thiophene derivative and 1 to 10 wt.% of a surfactant (C), on at least the single surface of a polyester film. The surface resistivity of the film surface of the laminated film under an atmosphere with a temperature of 23 deg.C and a humidity of 50% is 2×10<7> to 5×10<9> Ω/cm<2> . |
