Abstract

A hard coat laminated film according to at least one embodiment has, from the surface layer side, a first hard coat and a transparent resin film layer. The first hard coat is formed from a coating material including: (A) 100 parts by mass of a polyfunctional (meth)acrylate; and (B) 1-100 parts by mass of an N-substituted (meth)acrylamide compound. The transparent resin film has a first hard coat forming surface which is a poly(meth)acrylic imide resin. A hard coat laminated film according to another embodiment has, from the surface layer side, a second hard coat, the first hard coat and the transparent resin film layer. The second hard coat is formed from a coating material which includes: (A) 100 parts by mass of a polyfunctional (meth)acrylate; (E) 0.01-7 parts by mass of a water repelling agent; and (F) 0.01-10 parts by mass of a silane coupling agent; without inorganic particles.
