Abstract: A pen-input surface material has a surface on which an input is to be performed with a pen. The surface has ten-point average roughness (Rzjis) ranging from 0.1 ?m to 6 ?m inclusive, an average space between asperities (RSm) ranging from 30 ?m to 500 ?m inclusive, and skewness (Rsk) of zero or higher.

Abstract: An optical layered product has a translucent substrate having at least an optically functional layer, containing translucent microparticles, provided directly or via another layer onto one or both sides of the substrate. The standard deviation of area dispersion variability of the translucent microparticles in the optically functional layer is in the range of 0.04 to 0.20.

Abstract: 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%.

Abstract: An optical layered film includes a transparent substrate on which a radiation curing resin layer containing translucent resin fine particles is layered, which has an internal haze value (X) and a total haze value (Y) satisfying Y>X, Y?X+11, Y?50 and X?15, and has fine irregularity shapes on the outermost surface of the resin layer.

Abstract: An anti-glare material comprises irregularity shape formed over at least one side. The side comprising the irregularity shape has slope angles satisfying the distribution conditions according to the formulae (1) and (2): A?0.2??(1) and 0.8?B?2.5??(2) wherein A: proportion of slope angles at or greater than 1.6° in relation to the total, B: (proportion of slope angles at or greater than 0.4° and smaller than 1.6° in relation to the total)/(proportion of slope angles less than 0.4° in relation to the total).
