PROBLEM TO BE SOLVED: To provide a release film in which failures caused by electrostatic charge are prevented, and for example, when exposed to a high temperature, an oligomer can be highly prevented from being precipitated from the film and the occurrence of failures caused by the oligomer is prevented.SOLUTION: There is provided a release film which has a coating layer obtained by applying a coating liquid containing a quaternary ammonium group-containing polymer and a polyvalent aldehyde compound on one surface of a biaxially-stretched polyester film and has a mold releasing layer on another surface. |
