US 2014/0227482 A1 · OPTICAL LAMINATE

Abstract

There is provided an optical laminate excellent in adhesiveness between a (meth)acrylic resin film (base material film) having low moisture permeability and a UV absorbing ability and a hard coat layer, and has suppressed interference unevenness. An optical laminate according to an embodiment of the present invention includes: a base material layer formed of a (meth)acrylic resin film; a hard coat layer formed by applying a composition for forming a hard coat layer to the (meth)acrylic resin film; and a penetration layer formed through penetration of the composition for forming a hard coat layer into the (meth)acrylic resin film, the penetration layer being placed between the base material layer and the hard coat layer, wherein the penetration layer has a thickness of 1.2 μm or more.
