Embodiment 1
[0220] A PET film (Mitsubishi Plastics Co., Ltd., PET, thickness 75 μm) was used as the transparent resin layer, and the AWM layer coating liquid AWM-1 was coated on the film with a wire bar coater #10, and then the coating was carried out at 80°C. Let dry for 1 minute. Pass the coating film through an ultraviolet irradiation device (manufactured by Ushio Co., Ltd., high-pressure mercury lamp, ultraviolet irradiation amount: 100mJ / cm 2 ) and UV-cured to form an AWM layer with a surface concave-convex structure. The thickness of the AWM layer in the obtained transparent laminated film was about 3 μm.
Embodiment 2~9 and comparative example 1~4
[0222] A transparent multilayer film was produced in the same manner as in Example 1 except that AWM-2 to 13 were respectively used instead of AWM-1 as the AWM layer coating liquid.
[0223] Table 1 shows the evaluation results of the transparent laminated films obtained in Examples 1-9 and Comparative Examples 1-4.
[0224]
Embodiment 10
[0226] On the AWM layer of the transparent laminate film obtained in Example 4, the low-refractive-index layer coating liquid LC was applied using a wire bar coater #4, and dried at 70° C. for 1 minute. Then, the coating film was passed through an ultraviolet irradiation device (manufactured by Ushio Co., Ltd., high-pressure mercury lamp, ultraviolet irradiation amount: 100mJ / cm 2 ) were subjected to UV curing to form a low refractive index layer. The thickness of the low-refractive index layer in the obtained low-reflection transparent laminated film was about 100 nm.
