Kind Code:
A1
Abstract:
The present invention provides a hard coat film having a substrate and a hard coat layer formed on at least one surface of the substrate. The hard coat layer contains a compound having a silsesquioxane structure. The hard coat film has an elasticity difference ∆σ of 1800 to 4900 MPa, where the elasticity difference ∆σ is expressed by σA – σB, σA is the elasticity of the substrate and σB is the elasticity of the hard coat layer. The substrate has an elasticity of 6.0 to 9.0 GPa. The hard coat layer has a recovery rate as measured by an indentation test of 84 to 99%. The present invention also provides an article provided with the hard coat film and an image display device.
