HARD COAT FILM, PLASTIC SUBSTRATE, COMPOSITION FOR FORMING HARD COAT FILM, AND TOUCH PANEL

摘要

PROBLEM TO BE SOLVED: To provide a hard coat film that is excellent in hard coat property and antiblocking property and has a refractive index adjusted to suppress visibility of an electrode pattern, a plastic substrate including the hard coat film, a composition for forming a hard coat film from which a hard coat film having an adjusted refractive index can be formed, and a touch panel.SOLUTION: The hard coat film has an arithmetic average roughness Ra of a surface of 3 nm or more and 6 nm or less, 300 or more and 1000 or less projections having an average height or more per 400 μmsurface on the surface thereof, and a refractive index of 1.52 or more.
