Title:
OPTICAL LAMINATE
Document Type and Number:
WIPO Patent Application WO/2015/046245
Kind Code:
A1
Abstract:
Provided is an optical laminate which comprises a base layer and a hard coat layer, and has a sufficient hardness, while being prevented from interference irregularity.
An optical laminate which comprises: a base layer that is formed of a thermoplastic resin film; and a hard coat layer that is formed by coating the thermoplastic resin film with a hard coat layer-forming composition containing a curable compound having a molecular weight of 600-2,500 and high-refractive-index fine particles having a refractive index of 1.50 or more. The hard coat layer has a permeation region that is formed by permeation of the hard coat layer-forming composition into the thermoplastic resin film. The high-refractive-index fine particles are segregated in the hard coat layer so that the concentration thereof is continuously decreased from the surface, on which the base layer is not arranged, in the thickness direction.
