Transparent stamper for molding optical multi-layer recording medium and process for producing optical multi-layer recording medium

摘要

A stamper having a good cost performance, which can be easily separated (released) from a layer of photo-curing resin, is provided. A process for producing an optical multi-layer recording medium having a good productivity is also provided by using such a stamper. The process for producing an optical multi-layer recording medium includes the steps of: laminating a layer of non-cured photo-curing resin and a transparent stamper made of amorphous polyolefin resin in this sequence on a substrate; curing the non-cured photo-curing resin with light permeated through the transparent stamper; and removing the transparent stamper.
