    摘要: A process for the preparation of a substrate for an optical disk having spiral or concentric guide grooves formed on the surface thereof, which comprises the steps of casting a radiation- and heat-curable liquid resin mixture between a duplicating mold and a transport substrate, curing the liquid resin mixture by irradiating it with radiation from the side of the transparent substrate, peeling the molded body from the duplicating mold and heat-polymerizing the obtained molded body by heating, wherein a mixture comprising a liquid resin having a terminal acrylic group and/or a terminal methacrylic group and an organic peroxide is used as the radiation- and heat-curable liquid resin mixture.
