<p>[Problem] To provide: an antistatic hardcoat film which has saponification resistance and is capable of maintaining antistatic properties and transparency by preventing the antistatic properties of a hardcoat layer, in which an antistatic agent is blended, from deterioration even in cases where saponification is carried out with use of an aqueous alkaline solution; and a polarizing plate and an image display device, each of which uses the antistatic hardcoat film. [Solution] In an antistatic hardcoat film (10), a hardcoat layer (2), which is provided on a transparent base film (1) that is composed of triacetyl cellulose, is formed to contain, as an antistatic agent, a quaternary ammonium salt polymer having a molecular weight of 1,000-50,000. A urethane-based multifunctional acrylate compound represented by formula [1] and having an isocyanuric acid skeleton and a 15-functional (meth)acryloyl group (Ac) is used as a resin content to be combined with the quaternary ammonium salt polymer. A low-refractive-index layer (3) may be arranged on the hardcoat layer. (In the formula, R represents a dipentaerythritol residue.)</p> |
