PURPOSE:To provide the optical recording disk which is stuck with the adhesive surfaces of two sheets of substrates with recording layers uniformly over the entire surface and is improved in the productivity CONSTITUTION:This optical recording disk is constituted by sticking two sheets of the substrates 3a, 3b with the recording layers having the recording layers 2 via adhesive layers 4 to one surface of the substrates 1 in such a manner that the recording layers 2 face each other. A reaction initiator is added to the adhesives constituting the adhesive layers 4. These adhesive layers 4 are cured by the polymn. reaction by the reaction initiator and the photopolymn. reaction by irradiation with UV rays. |
