Abstract
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.
Claims15
An optical layered body comprising
- 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 (cut patterns) of the hard coat layer exists in the region of the light transmitting substrate via the antistatic layer from the hard coat layer:
- and
- wherein the hard coat layer is formed on the antistatic layer.
A method for producing an optical layered body comprising an antistatic layer and a hard coat layer formed in sequence on a light transmitting substrate,
- wherein the antistatic layer is formed from a heat drying composition containing an antistatic agent and a thermoplastic resin;
- the hard coat layer is formed from a composition for hard coat layers containing a resin and a solvent;
- and
- the solvent has solubility for the thermoplastic resin of the antistatic layer.
