ABSTRACT:
A method for producing an optical disc including the step of transferring a pattern of alternate projections and recesses from a stamper to a glass base plate by photopolymerization of a resin curable with ultraviolet rays, wherein the glass base plate is previously processed by surface processing by a suitable coupling agent. Before or after the surface processing with the coupling agent, the glass base plate is heated under a reduced pressure for improving bonding properties between the glass base plate and the resin curable with ultraviolet rays.
