PROBLEM TO BE SOLVED: To make it possible to minimize the peeling rate dependency when using a substrateless double-sided pressure-sensitive adhesive sheet in optical applications such as a touch panel, a liquid crystal deflecting plate, a phase difference plate, etc. An inexpensive polyester film for a double-sided pressure-sensitive adhesive sheet free from problems is provided. A release film in which a coating layer and a release layer are sequentially provided on one side of a polyester film stretched at least in a uniaxial direction, and the coating layer includes a conductive compound (A) and a binder polymer (B). The release layer has a reactive silicone resin having an alkenyl group and an alkyl group as a functional group, an unreactive silicone resin having a mass average molecular weight of 400,000 or more, and a silicone release layer containing a platinum-based catalyst. A polyester film characterized by that. [Selection figure] None |
