Document Type and Number:
Japanese Patent JP2016168688
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a release film which has an improved balance of releasability and followability, and is excellent in wrinkle resistance and stain resistance.SOLUTION: A release film has a release layer containing a polyester resin material on at least one surface. When one surface of the release layer of the release film is overlapped by the other surface in an opposite side to a surface having the release layer of the release film, the film is pressurized at a load of 1 kg for 0.5 minutes, then the one release film and the other release film are peeled from each other on the condition of a temperature of 25°C at a peeling speed of 300 mm/min, and a peeling charged voltage of the surface of the release layer of the one release film immediately after peeling is represented by Q, |Q| is 100 V or more and 1,000v or less.SELECTED DRAWING: None
