<P>PROBLEM TO BE SOLVED: To provide a mold-releasing polyester film which can attain high precision in an optical examination by the crossed nicols method for a polarizing plate and achieve foreign matter-reducing performance to process staining and adhesives. <P>SOLUTION: The mold-releasing polyester film having a coating layer obtained by coating one side of a polyester film with a coating liquid containing polyvinyl alcohol, and having a silicone-based mold-releasing layer on the coating layer is characterized in that the transparency of the mold-releasing film is ≥83.5%; the surface roughness (Ra) of the silicone-based mold-releasing layer is ≥9.0 nm; the MOR value of the mold-releasing film is 1.5-3.0. <P>COPYRIGHT: (C)2013,JPO&INPIT |
