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 &#x3bc;m&#x2264;&#x2264;18 &#x3bc;m&#x2003;&#x2003;Formula (1)0.3&#x2264;0.9&#x2003;&#x2003;Formula (2)2 &#x3bc;m&#x2264;&#x2264;11 &#x3bc;m&#x2003;&#x2003;Formula (3)where T denotes the total thickness (&#x3bc;m) of the permeation layer and the hard coat layer, and t denotes the thickness (&#x3bc;m) of the permeation layer.

Antistatic hardcoat film, process for producing same, polarizer, and image display device

The present invention provides an optical layered body having excellent antistatic properties, optical characteristics, hardness, adhesion, and interference fringe prevention performance, which can be produced at a low cost. An optical layered body having a hard coat layer provided on a triacetylcellulose substrate, wherein a resin composition used for forming the hard coat layer contains a quaternary ammonium salt-containing polymer, a binder resin, and a solvent; the quaternary ammonium salt-containing polymer has a higher hydrophilicity than the binder resin; and the binder resin contains two or more resin components having different hydrophilicities.

Optical layered body, polarizer and image display device

The claimed invention provides an antireflection film including a light-transmitting substrate, a hard coat layer, and a low-refractive-index layer, the hard coat layer and the low-refractive-index layer being formed on the light-transmitting substrate, the low-refractive-index layer including a (meth)acrylic resin, hollow silica particles, reactive silica particles, and two kinds of antifouling agents, the hollow silica particles having an average particle size of 40 to 80 nm and a blending ratio to the (meth)acrylic resin, represented by a ratio: Amount of hollow silica particles/Amount of (meth)acrylic resin, of 0.9 to 1.4, the amount of the reactive silica particles being 5 to 60 parts by mass based on 100 parts by mass of the (meth) acrylic resin, the antifouling agents including an antifouling agent that contains a fluorine compound and an antifouling agent that contains a fluoro-silicone compound.
