Embodiment
[0314] Hereinafter, an Example and a comparative example are shown, and this invention is demonstrated more concretely.
[0315] In addition, the following "part" means a weight part, and "%" means a weight%.
[0316] 1. Embodiment 1~Example 7, Comparative Example 1~Comparative Example 4
[0317] 1) Manufacture of the composition
[0318] The components shown in the following Tables 1 to 3 were mixed in the proportions shown in the table, and further mixed using an autorotation / revolution mixer [Awatori Rentaro ARE-250 manufactured by Thinky Co., Ltd.] (1,800 rpm x 4 minutes) And defoaming (2,000rpm x 1 minute).
[0319] It should be noted that the meanings of the abbreviations in Tables 1 to 6 are as follows.
[0320] (A) Ingredients
[0321] ・OT-1000: Addition reaction product of pentaerythritol triacrylate and hexamethylene diisocyanate (urethane adduct having six acryloyl groups in one molecule. Hereinafter referred to as "adduct") and pentaerythritol Tetraacryl...
Embodiment 8～ Embodiment 10
[0363] 2. Embodiment 8~Example 10, comparative example 5
[0364] 1) Manufacture and evaluation of composition and resin sheet
[0365] Resin sheets were produced and evaluated in the same manner as in Examples 1 to 7 except that the cured product obtained after ultraviolet irradiation was heat-treated in a nitrogen stream at 120° C. for 5 hours. Table 4 shows the compounding composition and evaluation results.
[0366] In addition, as Comparative Example 4, polycarbonate [Iupilon NF-2000 manufactured by Mitsubishi Gas Chemical Co., Ltd.], which is a representative tough thermoplastic resin, was used. Hereinafter abbreviated as "EUP". ], and evaluated by the same method as in Example 1 to Example 7. The evaluation results are shown in Table 4.
[0367] [Table 4]
[0368]
[0369] 2) Summary
[0370] According to the results in Table 4, the resin sheet obtained from the composition of Example 8 of the present invention had high hardness, was excellent in the resu...
Embodiment 11～ Embodiment 12
[0375] 3. Embodiment 11~Example 12, Comparative Example 6 (Example with a thickness of 100μm)
[0376] 1) Manufacture and evaluation of composition and resin sheet
[0377] Using the composition of the present invention, a resin sheet of a comparative film was produced and evaluated.
[0378] A composition was produced by the same method as in Example 1 to Example 7.
[0379] A cycloolefin polymer film [Nippon Zeon Co., Ltd.] with a thickness of 100 μm was used. Product name: ZEONOR ZF14. Hereinafter referred to as "ZEONOR ZF". ) was used as a substrate, and the obtained composition was formed into a coating film with a thickness of about 100 μm using an applicator, and ZEONOR ZF was further coated on it while paying attention to preventing bubbles from entering.
[0380] The laminate was irradiated with ultraviolet rays to cure the composition.
[0381] The ultraviolet irradiation conditions are: use X0602, the illuminance is about 240mW / cm 2 , The conveying speed i...
