ABSTRACT:
A hardcoat agent composition comprising a fluorine-containing polyether compound (A) having a perfluoropolyether unit, urethane bond and active energy ray reactive group and a curable compound (B) having equal to or more than 2 active energy ray polymerizing groups in the molecule. An optical information medium having a film substance composed of single or multiple layers containing at least the recording layer4or the reflecting layer on the supporting substrate20, the optical information medium wherein at least either the surface of the supporting substrate20or that of the above-mentioned film substance is formed by the hardcoat layer8containing a curable substance of the above-mentioned hardcoat agent composition.
