Patent ID: 8778489

Claim:
An optical layered product comprising a translucent substrate and at least an optically functional layer containing first translucent microparticles and second translucent microparticles, the optically functional layer being provided directly or via another layer onto one or both sides of the translucent substrate, wherein the first translucent microparticles have a lower refractive index than the second translucent microparticles; 95% or more, in number, of the first and second microparticles have an actual particle size in the range of 1 to 20 μm as observed by electron microscopy; the optical layered product having irregularities on an outermost surface of the optical functional layer; the first translucent microparticles being more abundantly contained in the optically functional layer closer to a surface thereof than to the translucent substrate; and the specific gravity of the first translucent microparticles being small than the specific gravity of the second translucent microparticles.
