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.

Optical laminated body

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&#xb0; C. or higher or a resin obtainable by a reaction between a resin having a glass transition temperature of 60&#xb0; C. or higher and a cross-linking agent.

Optical layered body, polarizer and image display device

An optical layered body wherein the additive amount of the antistatic agent can be reduced leading to a cost reduction while achieving high antistatic property simply and at a low cost. An optical layered body including an optical layered body comprising a light-transmitting substrate and at least a hard coat layer and a low refractive index layer, firmed on the light-transmitting substrate, wherein 1) the low refractive index layer is formed on the outermost surface, and 2) the low refractive index layer contains an antistatic agent.

Optical layered body, polarizer, and image display device

An optical layered body having an excellent antistatic property and adhesion is provided. An optical layered body is provided that comprises an antistatic layer and a hard coat layer formed in sequence on a light transmitting substrate, wherein in the cross-sectional appearance of the layered body, the cross-section phase of the hard coat layer exists in the region of the light transmitting substrate via the antistatic layer from the hard coat layer.
