发明名称 Optical laminated body
摘要 The present invention discloses an antistatic optical laminate. The optical laminate comprises a light transparent base material and at least an antistatic layer provided on the light transparent base material, where the antistatic layer comprises an electroconductive polymer as an antistatic agent. Further, the surface of the antistatic layer has a concavoconvex shape, and the height of convexes in the antistatic layer are not less than 40 nm and not more than 300 nm.

主权项 1. An optical laminate comprising a light transparent base material, an antistatic layer provided on the light transparent base material, and a hard coat layer provided on the surface of the antistatic layer, wherein the light transparent base material is a triacetyl cellulose resin film, wherein the optical laminate is formed by forming the antistatic layer having a concavoconvex on the light transparent base material by using an electroconductive polymer dispersion liquid, applying a composition for a hard coat layer comprising an ionizing radiation curing resin and a penetrating solvent selected from esters and ketones on the antistatic layer to cause the composition for the hard coat layer to penetrate into the antistatic layer and the light transparent base material, and curing the ionizing radiation curing resin in the composition for the hard coat layer to form the hard coat layer such that the optical laminate has a flat surface, wherein the concavoconvex has convexities having a height of not less than 40 nm and not more than 300 nm and a width of not less than 40 nm and not more than 100 μm, and has concavities having a height of not less than 5 nm and not more than 40 nm and a width of not less than 10 nm and not more than 100 μm, wherein the convexities and concavities have a quadrilateral cross-section in a thickness direction of the antistatic layer, and wherein the light transparent base material and the antistatic layer are joined together and the antistatic layer and the hard coat layer are joined together, wherein the interface between the light transparent base material and the antistatic layer, and the interface between the antistatic layer and the hard coat layer are not observable under a laser microscope.
