Patent ID: 10073195

Abstract:
An optical layered body has a light-transmitting substrate and a hard coat layer formed on the light-transmitting substrate. The hard coat layer contains reactive irregularly shaped silica fine particles and a binder resin. The reactive irregularly shaped silica fine particles are unevenly distributed at the side of the light-transmitting substrate in the hard coat layer. The hard coat layer can be divided in its thickness direction into three equal regions (1)-(3), in an order from the interface on the side of the light-transmitting substrate. Ratios of reactive irregularly shaped silica fine particles in the regions (1)-(3) are 30 to 90% in area, 25 to 80% in area, and 10 to 35% in area, respectively. The ratios satisfy the following relationship: the ratio of the region (1)>the ratio of the region (2)>the ratio of the region (3).
