Abstract: Embodiments relate to a hard coat laminated film having a first hard coat, a second hard coat, and a transparent resin film layer, where: the first hard coat is formed from paint which contains predetermined amounts of (A) a multifunctional (meth)acrylate, (B) a water repellent, and (C) a silane coupling agent, and which does not contain inorganic particles; and the second hard coat is formed from paint containing predetermined amounts of (D) a polymerizable compound and (E) inorganic fine particles having an average particle size of 1-300 nm. The (D) polymerizable compound contains: (d1) a multifunctional (meth)acrylate having three or more (meth)acryloyl groups in one molecule; (d2) a compound having two or more secondary thiol groups in one molecule; and optionally, (d3) at least one (meth)acrylate selected from the group consisting of a (meth)acrylate having two (meth)acryloyl groups in one molecule, a (meth)acrylate having one (meth)acryloyl group in one molecule, and a urethane(meth)acrylate.

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.
