Patent ID: 8124215

Claim:
A hard-coated antiglare film, comprising: a transparent plastic film substrate; and a hard-coating layer that contains fine particles and formed on at least one surface of the transparent plastic film substrate, wherein the hard-coating layer has a thickness of 15 to 30 μm, the fine particles have a weight average particle size of 30 to 75% of a thickness of the hard-coating layer, an average tilt angle θa of the unevenness of the hard-coating layer surface is in the range of 0.4° to 1.5°, the θa is defined by the mathematical formula (1), Average tilt angle θ a =tan −1 Δa (1); wherein Δa is a value obtained by dividing a sum total of differences (heights h) between the adjacent peaks and a lowest point of a trough formed therebetween by a standard length L of a roughness curve defined in JIS B0601 (1994 version); the hard-coating layer is formed using a material for forming the hard-coating layer containing Component A, Component B, and Component C, a ratio of Component B with respect to Component A in the hard-coating layer is in a range of 70% to 180% by weight, a ratio Component C with respect to Component A in the hard-coating layer is in a range of 25% to 110% by weight, and a ratio of the fine particles with respect to 100 parts by weight of the hard-coating material in the hard-coating layer is in a range of 2 to 70 parts by weight, wherein Component A is at least one of urethane acrylate and urethane methacrylate, Component B is at least one of polyol acrylate and polyol methacrylate, and Component C is a polymer or copolymer that is formed of at least one of Components C1 and C2, or a mixed polymer of the polymer and the copolymer, wherein Component C1 is alkyl acrylate having an alkyl group containing at least one of a hydroxyl group and an acryloyl group, and Component C2 is alkyl methacrylate having an alkyl group containing at least one of a hydroxyl group and an acryloyl group.
