One aspect of the present invention is a hardcoat multilayer film which comprises a first hardcoat and a transparent resin film layer in this order from the surface layer side, wherein the first hardcoat has been formed from a coating material that comprises (A) 100 parts by mass of a copolymer of (al) a polyfunctional (meth)acrylate and (a2) a polyfunctional thiol, (B) 0.01-7 parts by mass of a water repellent, and (C) 0.1-10 parts by mass of fine resin particles having an average particle diameter of 0.5-10 µm and that contains no inorganic particles. Another aspect of the present invention is a hardcoat multilayer film which comprises a first hardcoat and a transparent resin film layer in this order from the surface layer side, wherein the first hardcoat has been formed from a coating material that comprises (A) a copolymer of (al) a polyfunctional (meth)acrylate and (a2) a polyfunctional thiol, (B) a water repellent, and (C) fine resin particles having an average particle diameter of 0.5-10 µm and that contains no inorganic particles, and which satisfies given requirements concerning abrasion resistance, total light transmittance, and the Y value of the XYZ color system based on a 2-degree field of view.
