摘要： A process for making a release sheet which is non-silicone based and has good releasability from a pressure sensitive adhesive layer and which makes it possible to form a release agent layer at low temperature, having solvent resistance. The process comprises coating a substrate film with a release agent liquid, drying, and curing, to give a release agent layer, wherein the release agent layer is a cured layer obtained by irradiating a diene base polymer containing an intermolecular cleavage photopolymerization initiator with an active energy beam.
