[Examples 1 to 10 and Comparative Examples 1 to 2] On one surface of a triacetonitrile cellulose film having a thickness of 80 μm, the coating composition prepared in the above Preparation Example was applied as shown in Table 1 below, and then dried by heating, An anti-glare antireflection film is produced by ultraviolet curing. At this time, the coating liquid of Preparation Example 7 was applied in the case of Comparative Example 2, and then the low refractive coating liquid TU-2189 (manufactured by JSR, refractive index: 1.35) was cured on the above anti-glare coating. Thereafter, coating was carried out so as to have a thickness of 1 〇〇 nm, and then dried and UV-cured to prepare an anti-glare antireflection film. <Test Example> The physical properties of the prepared antiglare antireflection film were measured as follows, and the results are shown in Table 1 below. 1) Ra (μηι ) After the prepared anti-glare anti-reflection film was bonded to a black acrylic plate, the surface roughness was measured at a thousand-fold magnification by a confocal microscope (manufactured by Keyence Corporation, 'VK-9510). Degree (JISB〇6〇1). 2) Anti-glare property After the prepared anti-glare anti-reflection film was bonded to a black acrylic plate, the three-wavelength fluorescent lamp was reflected on the surface of the coating layer to confirm the outline of the fluorescent lamp, thereby evaluating the anti-glare. Sex. ◎: The outline of the fluorescent lamp cannot be confirmed. PI12DRA004TW 21/25 201247814 〇: Only the position of the outline of the fluorescent lamp can be confirmed, but the line is not clear.
