Embodiment 1

[0024] 100g of dipentaerythritol hexaacrylate, 10g of a monofunctional acrylate containing a perfluoro group having a structure of chemical formula 1 (X=F, Y=F, Z=H, h=6, i=1, excluding other components) , 5g photoinitiator Irgacure 184, 10g silica particles (average particle diameter is 20nm, the silica particles are surface treated with methacryloxypropyl trimethoxysilane), 10g antimony doped Zinc oxide (AZO, produced by Nissan, particle diameter about 20 nm) and 100 g of methyl ethyl ketone were mixed with each other, and the coating composition was stirred for about 1 hour to mix them well with each other. Using the coating composition prepared above, 2-roll reverse coating was performed so that the cured thickness on the triacetylcellulose film was 10 μm. The coated film was dried in an oven at 60 °C for 2 min and heated at 1 J / cm using a polymeric mercury lamp. 2 UV energy is irradiated on it with a certain intensity, so as to prepare a wear-resistant coating film with ...

Embodiment 2

[0026] A coating film was prepared in the same manner as in Example 1 except that 20 g of the antimony-doped zinc oxide (AZO, produced by Nissan, particle diameter about 20 nm) used in Example 1 was used.

Embodiment 3

[0028] A coating film was prepared in the same manner as in Example 1 except that 20 g of tin oxide (manufactured by Nissan, particle size about 20 nm) was used instead of antimony-doped zinc oxide.
