<P>PROBLEM TO BE SOLVED: To provide an optical disk which is provided with high reliability by suppressing the occurrence of warpage, etc., and a method for manufacturing the optical disk making it possible to manufacture the optical disk having good workability and the high reliability. <P>SOLUTION: The optical disk 10 formed by laminating at least two substrates 11 and 15 by a tacky adhesive layer 14 consisting of a film formed by curing a UV curing resin composition by thermal crosslinking and UV crosslinking is configured. In manufacturing such optical disk 10, the UV curing resin composition containing an acrylic resin having double bonds at side chains, a photopolymerization initiator and a thermal crosslinking agent is thermally crosslinked, by which the composition is half cured. The half cured resin and is bonded to one substrate 11. Another substrate 15 is laminated to this substrate 11 and thereafter the UV curing resin composition is UV crosslinked by irradiation with UV rays, by which the composition is cured and the tacky adhesive layer 14 for bonding the one substrate 11 and the other substrate 15 is formed. <P>COPYRIGHT: (C)2004,JPO |
