Claim 13:
14. A method for producing a hard coat film according to claim 10, the method comprising:
applying a primer layer paint to the cycloolefin polymer base film, followed by drying to form a primer layer, wherein the primer layer paint contains a modified polyolefin resin in which a polyolefin resin is graft-modified with an α,β-unsaturated carboxylic acid or a derivative thereof, and a (meth)acrylic acid ester, and the graft weight of the α,β-unsaturated carboxylic acid or derivative thereof is in the range of 0.4 to 7 wt. % when the amount of the modified polyolefin resin is taken as 100 wt. %;
then applying a hard coat layer paint containing an ionizing radiation curable resin to the primer layer, followed by drying to form a hard coat layer; and
then performing ionizing radiation irradiation.
