    • It is an object of the present invention to provide an optical layered body having sufficient hardness as an optical layered body and exhibiting a good antiglare property.An optical layered body, comprising a light-transmitting substrate and a hard coat layer formed on the light-transmitting substrate, wherein the hard coat layer comprises two layers of a clear hard coat layer (A) and a hard coat layer (B), the hard coat layer (B) has a surface roughness on the outermost surface and satisfies 0.0010≦φ≦0.14 0.25≦θa≦5.0 in the case where Sm is defined as a mean spacing of profile irregularities; θa is defined as a mean inclination angle of profile irregularities; Rz is defined as a mean roughness of the surface roughness; and φ is defined as Rz/Sm, and the optical layered body has substantially no interface between the clear hard coat layer (A) and the light-transmitting substrate.
    • 本发明的目的是提供一种具有足够硬度的光学层叠体作为光学层叠体并具有良好的防眩性。 一种光学层叠体,其包括透光性基板和形成在透光性基板上的硬涂层,其中,所述硬涂层包含两层透明硬涂层(A)和硬涂层(B), 硬涂层(B)在最外表面上具有表面粗糙度,在Sm被定义为轮廓不规则的平均间距的情况下,其表面粗糙度满足0.0010≦̸<&phl;≦̸ 0.14 0.25≦̸ &thetas; a被定义为轮廓不规则的平均倾斜角; Rz定义为表面粗糙度的平均粗糙度; 和&phgr 被定义为Rz / Sm,并且光学层叠体在透明硬涂层(A)和透光基板之间基本上没有界面。
