Abstract:
1. A process for producing an optical recording medium comprising an interlayer having a concavo-convex shape, the process comprising: (A) forming a first recording layer comprising an organic dye, on which information is to be recorded by applied light, on a substrate directly or via another layer, then (B) placing a curable resin material layer, formed by coating by spin coating a precursor of the curable resin, followed by a stamper having a concavo-convex shape for transfer corresponding to the concavo-convex shape on the first recording layer directly or via another layer, then (C) partially curing the curable resin material layer in the laminated state, thereby obtaining a bonded body comprising the substrate, the first recording layer, the curable resin material layer and the stamper, then (D) separating the stamper from the curable resin material layer so that the concavo-convex shape for transfer is transferred to the curable resin material layer, and applying surface modification treatment to promote curing of the curable resin material layer having transferred the concavo-convex shape for transfer, thereby forming the interlayer, and then (E) forming a second recording layer by applying a coating liquid comprising an organic dye on the surface of the interlayer.
