| 发明名称 | Optical layered body, polarizer and image display device | ||
| 摘要 | The present invention provides an inexpensive optical layered body which does not cause interference fringes but excels in hard coat properties, antistatic properties, and antireflection properties.;An optical layered body comprises: a light-transmitting substrate; and a hard coat layer (A) and a hard coat layer (B) on one face of the light-transmitting substrate in this order, wherein the hard coat layer (B) has a region (B1) not containing inorganic fine particles and a region (B2) containing inorganic fine particles, in this order from a portion adjacent to the hard coat layer (A), a boundary between the region (B1) not containing inorganic fine particles and the region (B2) containing inorganic fine particles has irregularities, and the inorganic fine particles have a particle size smaller than a visible light wavelength. | ||

| 主权项 | 1. An optical layered body, comprising: a light-transmitting substrate; and a hard coat layer (A) and a hard coat layer (B) on one face of the light-transmitting substrate in this order, wherein the hard coat layer (B) has a region (B1) not containing inorganic fine particles and a region (B2) containing inorganic fine particles, in this order from a portion adjacent to the hard coat layer (A), a boundary between the region (B1) not containing inorganic fine particles and the region (B2) containing inorganic fine particles has irregularities, the irregularities are formed depending on the presence of inorganic fine particles, and the inorganic fine particles have a particle size smaller than a visible light wavelength. | ||
