Optical layered object, polarizer obtained using same, and image display device

Abstract

Provided are an optical laminate including a resin layer on an acrylic base material in which the generation of an interference pattern is suppressed and the adhesiveness between the acrylic base material and the resin layer improves and a method for efficiently manufacturing the optical laminate. In the optical laminate including the resin layer on one surface of the acrylic base material, in a cross-section of the optical laminate in a thickness direction, an interface between the acrylic base material and the resin layer exhibits a ridge having crests and troughs and a length of the ridge corresponding to a standard length of 30 μm set in a direction perpendicular to the thickness direction of the optical laminate is in a range of 31 μm to 45 μm.
