摘要： In a process for producing a multilayered information recording medium of the present invention, a process for forming a second signal substrate (110) serving as a resin layer provided between a first thin film layer (102), which is a first information recording layer, and a second thin film layer (108), which is a second information recording layer, includes the steps of: (I) applying a liquid resin (104) onto the first information recording layer; (II) placing, on the resin (104), a signal transfer substrate (105) having a signal surface with a shape of projections and depressions; (III) curing the resin (104) while the signal transfer substrate (105) is placed on the resin (104); and (IV) separating the signal transfer substrate (105) from the resin (104). The signal transfer substrate (105) is formed of an organic-inorganic hybrid material, such as a cured silicone resin obtained by curing a silicone resin composition containing a silsesquioxane compound, that contains a molecular-size inorganic part having a polyhedral structure constituted by —Si—O— bonds and an organic segment crosslinking a plurality of the inorganic parts with each other.
