Abstract
It is an object of the present invention to provide an improved optical layered body with reduced scintillation, gloss blackness, color effects and interference fringes, while maintaining antistatic and antiglare performance. The optical layered body comprises, in order, an antistatic layer, an antiglare layer and a low refractive index layer on a light-transmitting substrate, The antistatic layer is a thin resin layer containing antimony-doped tin oxide and a diffusion filler, and having a predetermined surface roughness on its surface.
Claims20
An optical layered body comprising an antistatic layer, an antiglare layer and a low refractive index layer in an order on a light-transmitting substrate,
- wherein said antistatic layer is a resin thin layer containing antimony-doped tin oxide and a diffusion filler, wherein the diffusion filler is a silica and/or an organic resin bead, and
- wherein the low refractive index layer has a lower refractive index than that of the antiglare layer.
