摘要:
To provide a process for producing a laminated optical recording medium with improved production efficiency, with which in production of an optical recording medium by a 2P process, a resin forming an interlayer and a light transmitting stamper can easily be separated without applying any constrained load. A process for producing a laminated optical recording medium, which comprises applying a precursor of an ultraviolet-curing resin on a recording layer containing an organic dye formed on a polycarbonate substrate, disposing a polypropylene light transmitting stamper comprising a nonpolar member having a concavo-convex shape thereon, curing the ultraviolet-curing resin and then easily separating the light transmitting stamper without applying any constrained load so that the concavo-convex shape is transcribed on the resin layer.
