<p><P>PROBLEM TO BE SOLVED: To provide a surface protective film of a propylene-based resin which generates very few fish eyes and is suitable as a film for surface protection of; building elements such as synthetic resin plate, decorative plate, metal plate, and glass plate, and liquid crystal display components such as polarizing plate, phase difference plate, etc. <P>SOLUTION: In the surface protective film where an adhesive layer is formed on one side surface of a substrate layer comprising the propylene-based resin and an exfoliation processing layer is formed on the other side substrate, the surface protective film is characterized in that; the substrate layer is the propylene-based resin comprising a propylene homopolymer or a propylene-α-olefin random copolymer, which is polymerized using a metallocene catalyst and has specific MFR (Melt Flow Rate), fusion peak temperature, molecular weight distribution and TREF (Temperature Rising Elution Fractionation) value; that the adhesive layer is an ethylene-vinyl acetate copolymer resin having specific MFR and vinyl acetate content; and that center plane average roughness (SRa) on the layer surface of the exfoliation processing layer is within the range of 0.2-1.5μm. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
