摘要

PROBLEM TO BE SOLVED: To provide a hard coat film that is excellent in adhesion between a support substrate and a hard coat layer and pencil hardness, and can reduce interference fringe caused by a difference in refractive index between the support substrate and hard coat layer.SOLUTION: There is provided a hard coat film comprising a support substrate and a hard coat layer laminated on a single face of the support substrate, wherein the support substrate is formed of a first acrylic photocurable resin having at least one of a urethane skeleton, aromatic ring, and cyclic structure; the hard coat layer is formed of a second acrylic photocurable resin; the support substrate has a tensile strength of 25 to 40 N/mm; the support substrate has a tensile elongation defined by the following formula of 10% or more and a pencil hardness of 2H or more. Tensile elongation={(length at break)-(initial length before pulling)}/initial length before pulling.SELECTED DRAWING: None
