<P>PROBLEM TO BE SOLVED: To provide a film which is improved in productivity caused by blanking properties in a process in which, when a release polyester film is used in optical applications, for example, a touch panel, a liquid crystal deflector, a retardation plate, etc., blanking the same film to a corresponding product size after sticking on a polarizing plate is carried out, deterioration in productivity caused by the generation of an oligomer by heating or pressurization in a polarizing plate sticking process, etc. <P>SOLUTION: In the release polyester film having a coating layer obtained by coating at least one side of a polyester film of 35-45% crystallinity with a coating liquid containing polyvinyl alcohol, the coating layer has a release layer containing 0.5-5.0 wt.% of at least one kind of a transition metal catalyst. <P>COPYRIGHT: (C)2012,JPO&INPIT |
