A high capacity optical information storage medium, e.g., a Blu-ray Disc, possesses a multilayer coating on a surface thereof, the coating comprising: a) a light transmission layer in adherent contact with a surface of the optical information storage medium, the light transmission layer being obtained by curing a first curable composition comprising at least one monomer possessing at least one of acrylate and epoxy functionality; and, b) a hardcoat layer in adherent contact with the light transmission layer, the hardcoat layer being obtained by curing a second curable composition comprising functionalized colloidal silica and at least one monomer possessing at least one of acrylate and epoxy functionality.
