Embodiment 1
[0264] In this embodiment, a vinyl-based polymer (acrylic resin) is first produced, and the vinyl-based polymer is formed into a film, and then an optical disc is produced by using the film.
[0265]
[0266] In a 500 mL autoclave, 200 g of acetone as a polymerization solvent was put, and then 66.5 g (58.4 mol %) of methyl methacrylate (MMA), 39.9 g (27.4 mol %) of butyl acrylate (BA), cyclohexyl 26.6 g (14.2 mol %) of lyimide and 0.4 g of lauroyl peroxide as a polymerization initiator were added to the monomer mixture to dissolve, and then the mixture was put into the flask. Then, nitrogen gas was circulated at room temperature (25° C.) for 1 hour to replace the dissolved oxygen gas, and then the temperature was raised to 60° C. under nitrogen gas flow. The same temperature was maintained for 18 hours to obtain an acetone solution of an ethylene-based polymer. The polymerization rate at this time is 99% or more.

Embodiment 2
[0291] In this example, except that no antioxidant and light stabilizer were added, the film was prepared according to the same method as in Example 1, and then the optical disc was prepared according to the method in Example 1. The same various evaluations as in Example 1 were performed, and the results are shown in Table 2.
Embodiment 3
[0293] In this example, after separately preparing two types of vinyl polymers according to the following method, a resin formed by mixing divinyl polymers in a specific ratio was made into a film, and then an optical disc to which the film was applied was fabricated. Wherein, except for changing the resin used in the film, the rest were carried out according to the same procedure and evaluation method as in Example 1. The results are listed in Table 2.
[0294]
[0295] First, an ethylene polymer (A) is obtained in the following steps. In a 500 mL autoclave, 200 g of acetone as a polymerization solvent was put, and then 38 g (33 mol %) of methyl methacrylate (MMA), 90 g (61 mol %) of butyl acrylate (BA), and 5 g of acrylic acid (AA) were weighed. (6 mol %), 0.4 g of lauroyl peroxide and a polymerization initiator were added to the monomer mixture to dissolve, and then the mixture was put into the flask. Then, nitrogen gas was circulated at room temperature for about 1 hou...
