されている。In order to achieve high-density recording in optical information recording media, it is necessary to form a concavo-convex optical information pattern on a base material for optical information recording media. For this reason, several molding methods have been proposed in the past, and the 2P method, which has extremely high transfer accuracy for fine information recording patterns, is currently being actively studied. This 2
In the P method, an optical information recording medium is prepared by filling a liquid ionizing radiation-curable resin composition between a stamper having an uneven surface and a base material for the optical information recording medium, and applying the resin composition to the base material side or It is formed by irradiating ultraviolet rays or electron beams from the stamper side to cure them, and then peeling off the stamper. The above-mentioned ultraviolet ray or electron beam curable resins generally include urethane acrylate, epoxy acrylate, polyester acrylate, and polyether. A blend of polymerizable monomers with acryloyl groups such as acrylate and melamine acrylate, or oligomers with monofunctional or polyfunctional Kami-1 or oligomers with polymerizable vinyl groups such as acrylic acid, acrylamide, acrylonitrile, and styrene is used. has been done.

報記録媒体の提供を可能とするものである。The present invention improves the adhesiveness between the curable resin and the base material for the optical information recording medium by producing an optical information recording medium using an ionizing radiation curable resin composition made of a highly polar and low viscosity resin. Therefore, since it is not necessary to provide a primer layer, the process for producing an optical information recording medium can be simplified and the production cost can be reduced. Furthermore, by using a curable resin with low viscosity, it is possible to prevent the inclusion of air bubbles, etc., thereby making it possible to provide an optical information recording medium with a low error rate.
