摘要:
Provided is a release sheet which is non-silicone-based and has a good releasability from a layer of a pressure sensitive adhesive and which has a stable antistatic property without being influenced by the air environment and is free of bleeding out of ionic substances derived from an antistatic agent. The release sheet is prepared by providing an undercoat layer containing a polyurethane-based resin and 0.1 to 45% by mass of a lithium salt-based antistatic agent and a layer of a rubber-based release agent formed by coating and drying a liquid containing a release agent in order on a substrate.
