Abstract
The claimed invention provides an antistatic hard coat film that is extremely excellent in white muddiness resistance and antistatic properties and sufficiently prevents an interference fringe pattern. The claimed invention provides an antistatic hard coat film including a triacetyl cellulose substrate and a hard coat layer formed on the triacetyl cellulose substrate, the hard coat layer including an antistatic agent, a (meth)acrylate resin, and a polymer of a (meth)acrylate monomer, the triacetyl cellulose substrate including a permeation layer formed by permeation of the (meth)acrylate monomer from the hard coat layer side of the interface toward the opposite side of the hard coat layer, the antistatic hard coat film satisfying Formulas (1), (2), and (3):3 μm≤≤18 μm  Formula (1)0.3≤0.9  Formula (2)2 μm≤≤11 μm  Formula (3)where T denotes the total thickness (μm) of the permeation layer and the hard coat layer, and t denotes the thickness (μm) of the permeation layer.
