| 主权项 | 1. A hard coat film comprising: a light-transmitting substrate; and a hard coat layer, wherein the hard coat layer comprises a cured product of a composition for a hard coat layer, the composition comprising an isocyanuric skeleton-containing urethane(meth)acrylate, wherein the isocyanuric skeleton-containing urethane(meth)acrylate is urethane acrylate obtained by reacting three terminal isocyanate groups of an isocyanurate, which is a trimer of hexamethylene diisocyanate and has an isocyanuric skeleton, with a polyfunctional monomer so as to form the isocyanuric skeleton-containing urethane(meth)acrylate, and wherein the isocyanuric skeleton-containing urethane(meth)acrylate contains 9 or more functional groups. | ||
