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.
Claims16
An optical layered body, comprising:
- an antistatic layer on a light-transmitting substrate and a hard coat layer on the antistatic layer,
- 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, and
- the antistatic layer is formed with a composition for forming an antistatic layer containing the organic conductive material, the nonconductive polymeric material and an organic solvent, and the composition for forming an antistatic layer is obtained by mixing the organic conductive material and the nonconductive polymeric material with the organic solvent and carrying out a dispersing treatment thereof, and
- the hard coat layer is formed with a composition for forming a hard coat layer containing at least a resin and solvent having permeability to the light-transmitting substrate and the antistatic layer.
