Abstract:
One embodiment provides a hard coat laminated film having, in order from a surface layer side, a first hard coat and a transparent resin film layer. The first hard coat includes a coating material not including inorganic particles and including: (A) 100 parts by mass polyfunctional (meth) acrylate; (B) 0.01-7 parts by mass water repellent; (C) 0.01-10 parts by mass silane coupling agent; and (D) 0.1-10 parts by mass resin microparticles having an average particle diameter of 0.5-10 μm. Another embodiment provides a hard coat laminated film having, in order from a surface layer side, a first hard coat, a second hard coat, and a resin film layer. The first hard coat includes a coating material that does not include inorganic particles. The second hard coat includes a coating material including inorganic particles. The adhesive film fulfills the conditions: (i) a total light transmission rate of at least 85%; (ii) a pencil hardness for the first hard coat surface of at least 5H; and (iii) a Y value for an XYZ color system of 1.5%-4.2%.
