ABSTRACT:
The present invention provides a hard coat agent composition that is useful for forming a hard coat layer with excellent anti-staining properties and lubricity, as well as superior scratch resistance and abrasion resistance, on the surfaces of various articles. The present invention also provides an optical information medium using the above hard coat agent composition. A hard coat agent composition comprising a fluorine-containing block copolymer (A1), a fluorine-containing polyether compound (A2) comprising an active energy ray-reactive group, and an active energy ray-curable compound (B). An optical information medium comprising a film element composed of one or more layers including at least a recording layer (4) or a reflective layer, on a supporting substrate (20), wherein at least one of the supporting substrate (20)-side surface and the film element-side surface is formed of a hard coat layer (8) comprising a cured product of the hard coat agent composition.
