Beschreibung
Zusammenfassung:	The purpose of the present invention is to provide a hard coat film which shows excellent temporal adhesion and high durability of a hard coat layer both under normal conditions and hot and humid conditions, even in the case of bonding to a base film having few polar groups and showing poor adhesion, for example, a cycloolefin film. The hard coat film according to the present invention, wherein a hard coat layer comprising an ionizing radiation curable resin is formed on at least one face of a base film, is characterized in that the ionizing radiation curable resin satisfies requirement (I). Requirement (I): peak area ratio 1 ((A/C)×100) is 5% or greater (wherein: A represents a peak area appearing within 3250-3500 cm-1 in infrared spectrometric measurement of the ionizing radiation curable resin in an uncured state; and C represents a peak area appearing within 1650-1800 cm-1 therein).
