Abstract:
1. An optical recording medium-producing sheet, comprising: a first release sheet comprising a first base material and a first release agent layer; an energy-beam curable stamper-receiving layer laminated on the first release agent layer of the first release sheet and having a storage elastic modulus before curing of 1×10 a second release sheet comprising a second base material and a second release agent layer, wherein the second release agent layer is laminated on the stamper-receiving layer on an opposite side to the first release sheet, wherein the second release agent layer has a release force of 50 to 200 mN/50 mm relative to the stamper-receiving layer, wherein the first release agent layer of the first release sheet is formed using a release agent that contains an MQ resin containing an alkenyl group and haying, as constituent components, M units represented by formula (1) wherein the release agent does not substantially contain particles consisting of inorganic matter, and wherein the first release agent layer of the first release sheet has a release force of 300 to 800 mN/50 mm relative to the stamper-receiving layer before curing.
