Abstract:
The present invention provides an optical layered body having a good antistatic performance and good optical properties as well as an excellent durability. The present invention provides an optical layered body, comprising: an antistatic layer on a light-transmitting substrate, wherein the antistatic layer is a resin thin film layer containing at least an organic conductive material and a nonconductive polymeric material which is a resin having a glass transition temperature of 60° C. or higher or a resin obtainable by a reaction between a resin having a glass transition temperature of 60° C. or higher and a cross-linking agent.
