An object of the present invention is to provide an antireflection film and a coating agent having high adhesion of layers constituting the antireflection film, high scratch resistance, and low minimum reflectance. SOLUTION: (a) a transparent base layer 13, (b) a hard coat layer 15, and (c) a low refractive index layer 17, and the layer structures (a) 13 to (c) 17 are provided. (a) 13 / (b) 15 / (c) 17, and (b) 17 is mainly composed of acrylate and 2-3 functional methacrylate, and the above 2 to 100 parts by weight of the acrylate. The antireflection film 19 is characterized in that the mixing ratio of the trifunctional methacrylate is in the range of 0.5 to 50 parts by weight. [Selection] Figure 3 |
