Abstract
Embodiments relate to a hard coat-laminated film for a touch panel display face plate, the hard coat-laminated film including: a transparent resin film, and a hard coat formed on at least one surface of the transparent resin film from a coating material including an active energy ray-curable resin composition. The hard coat-laminated film meets the following requirements (1-i) to (1-v): (1-i) a total light transmittance of 80% or higher, (1-ii) a haze of 3.0% or lower, (1-iii) a yellowness index of 3 or lower, (1-iv) a water contact angle of a touch surface of 100° or larger; and (1-v) a water contact angle of the touch surface of 100° or larger after 20,000-times reciprocal cotton wiping of the touch panel.
