    • In a composition layering one layer on a transparent substrate, the present invention provides an optical film which can balance anti-glare function, high contrast, color reproducibility, and anti-glittering enough. The optical film in the present invention comprises a transparent substrate, and a resin layer layered on the transparent substrate, the resin layer including transparent resin fine particles and a radiation-curable resin composition, and having a fine rugged structure of an average inclination angle in a range of 0.8° to 3.0° on the top surface of the resin layer; a haze value which is in a range of 40% to 60%; and a transmitted image clarity which is measured by using an optical comb having width of 0.5 mm and is in a range of 5% to 35%.
    • 在透明基板上层叠一层的组合物中,本发明提供了能够足够平衡抗眩光功能,高对比度,颜色再现性和防闪光性的光学膜。 本发明的光学膜包括透明基板和层叠在透明基板上的树脂层,树脂层包括透明树脂微粒和可辐射固化树脂组合物,并且具有平均倾斜角度的细小凹凸结构 在树脂层的上表面上为0.8°〜3.0°的范围; 雾度值在40%至60%的范围内; 以及通过使用宽度为0.5mm并在5%至35%的范围内的光梳来测量的透射图像清晰度。
