PURPOSE:To facilitate handling by providing the structure in which light transparent bases formed thereon with the films of recording layer parts consisting of recording layers and protective layers are stuck to each other to the above disk and forming an adhesive layer of a mixture composed of an epoxy resin and a photosetting resin. CONSTITUTION:This optical information recording disk has the structure in which the light transparent bases formed thereon with the films of the recording layer parts consisting of the recording layers and the protective layers are stuck to each other. The adhesive layer 5 is formed by curing the adhesive agent consisting of the mixture composed of the epoxy resin such as bisphenol F system which is curable by heat and the photosetting resin such as acrylate monomer or oligomer. Since the adhesive layer 5 can be partially cured by light in this case, the handling is easy at the time of curing the adhesive layer 5 by heat; in addition, the bleeding of the adhesive agent from the inner and outer circumferences of the substrates and the consequent staining of the substrate surfaces are obviated. |
