ABSTRACT:
An optical recording medium is made by a step of bonding a light-transmissive substrate to a supporting substrate having a brightness of 8 or more and a saturation of 4 or less via a bonding layer composed of an epoxy resin; and a step of forming a transparent ink-receiving layer on a surface of the supporting substrate remote from the light-transmissive substrate. The bonding using the epoxy resin is conducted by a method of curing the resin by using a cationic initiator, a method of curing the resin by an addition reaction between the resin and a crosslinking agent containing an active hydrogen compound, a method of curing the resin by heating, or the like. In this invention, the bonding layer is composed of a material containing an epoxy resin instead of a radically polymerizable UV-curable resin typically used. Thus, although UV irradiation through the supporting substrate is not possible, the light-transmissive substrate can be securely bonded to the supporting substrate.
