When the spin coating is about to end, the xenon flash lamp 2 is irradiated to the extent that it is hardened to have no surface fluidity. 4. Using a high pressure mercury lamp, it was irradiated at 400 mJ/cm2 for 3 seconds from the upper side to completely cure the ultraviolet curable resin composition of the present invention. 5. After curing, the ultraviolet curable resin composition of the present invention is placed on the rotating base, and subjected to a round cap treatment to cover the inner diameter of 1 l_5 mm, followed by BRD-864 (曰本Chemicals (shares) company made blue light 23 201125918 Disc light transmissive layer resin) 3.0 g was supplied to the central part cap. 6. Spin coating for 4 seconds to 7 seconds at a speed range of 1500 rpm to coat a coating film thickness of 75/zm. At the end of the spin coating, the xenon flash lamp was irradiated for 2 times to harden it to the extent that it had no surface fluidity. 7. The blue light disc of the present invention was produced by using a mercury lamp with a pressure of 4 〇〇 mj/cm 2 for 3 seconds from the upper side to completely harden the BRD-864. Fabrication of a Blu-ray Disc with Organic Pigment Recording Layer (Example 4) 1. Sputtering a silver alloy on a polycarbonate substrate having a guide groove of 0.32/zm and having a diameter of 12 cm and a thickness of 1 _ 1 mm The film thickness of 丨〇〇nm is formed to form a reflective layer. Then, a dye solution (azo dye/glutamate in TFP (tetrafluoropropanol) solvent) was applied by spin coating, and dried by go C for 30 minutes to form an organic dye recording layer. Further, a Blu-ray disc substrate was produced by extruding ZnS-SiO 2 (Morby 80: 20) to a thickness of about 1 5 nm to form an interface layer'. 2_ placing the Blu-ray disc substrate on the rotating base with the interface layer as a top, performing a round cap processing to cover the inner diameter of 11.5 mm, and then preparing the external hardening type resin composition of the present invention 2.0 g is supplied to the cap of the center. 3. The viscosity of the ultraviolet curable resin composition of the present invention is applied in a speed range of 800 rpm to 1300 rpm for 4 seconds to 7 seconds to coat a coating film having a thickness of 100 m. When the spin coating is about to end, the xenon flash lamp 2 is irradiated to the extent that it is hardened to have no surface fluidity. 4. The high-pressure mercury lamp was irradiated from the upper side at 400 mJ/cm 2 for 3 seconds to completely harden the ultraviolet curable resin composition of the present invention, and the blue light disc of the present invention was produced. Recording signal characteristics before and after the durability test of the Blu-ray disc The Blu-ray disc of the present invention and a comparative example are made! The Blu-ray disc was placed in an 8 〇, 85/6 RH environment for 25 〇 hours. Using the Blu-ray Disc data signal measuring device DU_1〇〇〇 manufactured by Pulstec, the recorded signal characteristics (jitter value) of the Blu-ray disc before and after the durability test were measured and evaluated on the basis of the following criteria. The jitter value is one of the electrical signals of the optical disc. The higher the value, the more the signal data of the Blu-ray disc has deteriorated. If it is more than 丨〇%, the reading and writing of the data becomes difficult. ... evaluation of the jitter value 〇...jitter value is less than 10% X...jitter value is 10% or more Appearance evaluation when the ultraviolet curable resin composition is preserved After adjusting the ultraviolet curable resin composition of the present invention and the comparative example, The appearance of the liquid was observed after storage for 24 hours at 251, 45% RH. In the case where the liquid has been separated at the time of storage, it is difficult to uniformly apply the ultraviolet curable resin composition and it is difficult to harden it. Evaluation of the appearance of the liquid 〇························································· The (fluorenyl) acrylate having an alkylene group having a carbon number of 7 to 18 has good coatability, and good recording nickname characteristics can be obtained before and after the durability test. On the other hand, in Comparative Example 1 (which does not contain a (fluorenyl) acrylate having an alkylene group having a carbon number of 7 25 201125918 to 18), good recording signal characteristics could not be obtained before and after the durability test. Further, in Comparative Example 2, the (meth) acrylate having no alkylene group having a carbon number of 7 to 18 was similarly contained, and the appearance of the separation of the liquid was caused by storage at room temperature for 24 hours. The present invention has been described in detail with reference to the specific embodiments thereof. It is understood that various changes and modifications can be made without departing from the spirit and scope of the invention. In addition, the present application is based on a patent application filed on Jan. 29, the entire disclosure of which is hereby incorporated by reference. Again, all references cited herein are incorporated by reference. Single simple diagram
