Abstract
(EN)
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.

La présente invention concerne un film de revêtement dur ayant un substrat et une couche de revêtement dur formée sur au moins une surface du substrat. La couche de revêtement dur contient un composé ayant une structure de silsesquioxane. Le film de revêtement dur a une différence d'élasticité ∆σ de 1 800 à 4 900 MPa, la différence d'élasticité ∆σ étant exprimée par σA – σB, σA étant l'élasticité du substrat et σB étant l'élasticité de la couche de revêtement dur. Le substrat a une élasticité de 6,0 à 9,0 GPa. La couche de revêtement dur a un taux de récupération de 84 à 99 % tel que mesuré par un test d'indentation. La présente invention concerne également un article pourvu du film de revêtement dur et un dispositif d'affichage d'image.
