摘要： The method of producing a two-disc laminated optical video disc, includes first forming, on a first substrate, a first reflecting film capable of partially reflecting and partially transmitting a laser beam. Next on a second substrate, a second reflecting film is formed having a reflectance higher than that of the first reflecting film. A liquid ultraviolet-setting resin is applied to the first reflecting film and/or the second reflecting film. The above treated first substrate and the second substrate are bonded together, with a light-transmissible middle layer interposed therebetween. The liquid ultraviolet-setting resin is solidified by means of an ultraviolet light directed from below the first substrate.

摘要： A method of producing an optical disc of bonded type includes the processes of: (A) forming a first reflection film, which is half transparent for partially reflecting and partially transmitting an incident light, on a first information record surface of a first transparent substrate; (B) forming a second reflection film, which has a reflective index higher than that of the first reflection film, on a second information record surface of a second transparent substrate; (C) dripping a liquid resin of ultraviolet hardening type onto one of the first and second reflection films by a spin coating method to form a first resin layer in a non-hardened condition; (D) dripping a liquid resin of ultraviolet hardening type onto the other of the first and second reflection films by a spin coating method; (E) emitting ultraviolet onto the liquid resin dripped by the process (D) to form a second resin layer of ultraviolet hardening type in a hardened condition; (F) provisionally bonding the first and second transparent substrates together in a pressure reduced environment; and (G) hardening the first resin layer by emitting ultraviolet from a side of the first transparent substrate.

摘要： A laminate optical disc which has excellent heat resistance and also has sufficient bond strength. Radiation-curing adhesive layers are formed on a pair of transparent base plates excluding the outermost circumferential portions, respectively, and an ultraviolet-curing resin is applied to the outermost circumferential portion. Then, the pair of transparent base plates are bonded together by the radiation-curing adhesive layers, and also ultraviolet light is irradiated to the ultraviolet-curing resin to fix the base plates firmly to each other along the outermost circumferential portions. In a process for producing a laminate optical disc, radiation-curing adhesive layers are formed respectively on a pair of transparent base plates, and then irradiated with a radiation excluding at least the outermost circumferential portion to be tackified. After the thus treated base plates are bonded together by the radiation-curing adhesive layers, the outermost circumferential portions of these layers are irradiated until they lose tackiness.
