The present invention provides an ultraviolet-ray-curable composition for cyclic olefin resins, which is characterized by comprising, as the essential components, an ultraviolet-ray-curable compound (A) and a photopolymerization initiator (B) that is a compound having at least two groups each represented by formula (1) per molecule. When the ultraviolet-ray-curable composition for cyclic olefin resins according to the present invention is applied on the surface of a cyclic olefin resin and then cured, a hard coat layer which comprises a hard coating film that has high scratch resistance and excellent adhesion to the cyclic olefin resin and rarely undergoes discoloration can be produced.
