Hard coat film

Abstract

A hard coat film 10 includes a base material 11, and a hard coating layer 12 composed of a cured product of a resin composition containing a resin (A) and a resin (B), the hard coating layer 12 being laminated on the base material 11. The resin (A) is a polyfunctional (meth)acrylic monomer having a weighted average of functionality of more than or equal to 4. The resin (B) is an aliphatic urethane acrylate. A glass transition temperature Tg of the hard coating layer 12 is more than or equal to 50° C. and less than or equal to 100° C. In a case of measuring a loss tangent tan δ of the hard coating layer 12 by dynamic viscoelastic measurement of applying a 1-Hz frequency dynamic load, the loss tangent tan δ at the glass transition temperature Tg is more than or equal to 0.07 and less than or equal to 0.15.
