According to the present invention, there is provided a release film that can be suitably used in various applications without suffering from deterioration in releasing property thereof, for example, owing to a solvent used upon processing an adhesive layer, when the film is used as a release film for adhesives or a protective film for an adhesive layer for a polarizing plate. The release film of the present invention comprises a polyester film and a coating layer formed on at least one surface of the polyester film, the coating layer comprising a silicone compound and a Gemini surfactant.

Release film

The present invention provides a polyester film that can be suitably used in the applications requiring excellent transparency and slipping property, for example, such as a film member for a transparent electrode used in touch panels, etc., and a member for molding films. The present invention relates to a polyester film comprising non-heat-resistant particles supported thereon, in which after supporting the non-heat-resistant particles on at least one surface of an unstretched polyester film, the unstretched polyester film is stretched in at least one direction thereof, and a process for producing a polyester film comprising the steps of blowing non-heat-resistant particles onto at least one surface of an unstretched polyester film to support the non-heat-resistant particles thereon, or applying a coating solution comprising the non-heat-resistant particles onto at least one surface of the unstretched polyester film to support the non-heat-resistant particles thereon; and then stretching the unstretched polyester film in at least one direction thereof.
