Document Type and Number:
WIPO Patent Application WO/2014/103686
Kind Code:
A1
Abstract:
Provided are an optical layered object comprising an acrylic substrate and a resin layer formed thereon and a process for efficiently producing the optical layered object. The optical layered object is effective in inhibiting the occurrence of interference fringes and has improved adhesion between the acrylic substrate and the resin layer.
The optical layered object comprises an acrylic substrate and a resin layer formed on one surface thereof, wherein in a thickness-direction cross-section of the optical layered object, the interface between the acrylic substrate and the resin layer appears a ridgeline having protrusions and recesses, the length of the ridgeline being 31-45 μm per reference length of 30 μm taken in the direction perpendicular to the thickness direction of the optical layered object.
