Document Type and Number:
WIPO Patent Application WO/2016/129486
Kind Code:
A1
Abstract:
An optical layered body provided with a substrate and an adhesive layer formed on the substrate, the adhesive layer including light-scattering particles and an acrylic adhesive composition including an acrylic polymer, the acrylic polymer being a copolymer of a copolymerizing component (I) including 40 wt% to 93 wt% of an aromatic-ring-containing monomer (a1) and 7 wt% to 60 wt% of a hydroxyl-group-containing monomer (a2), the weight-average molecular weight of the acrylic polymer being 200,000 or less, the volume concentration V of the light-scattering particles with respect to the adhesive layer being 3%-35%, the refractive index of the acrylic adhesive composition being 1.52 to 1.67, and the refractive index of the light-scattering particles being 1.4 to 1.49.
