摘要:
One embodiment of the present invention is a multilayer hard coating film which sequentially comprises, from the superficial layer side, a first hard coating and a resin film, and wherein: the first hard coating is formed from a coating material that contains a specific amount of (A) a polyfunctional (meth)acrylate and a specific amount of (B) a water repellent agent, while containing no inorganic particles; and the resin film comprises at least one layer of (α) an acrylic resin that contains 50-95% by mole of a structural unit derived from methyl methacrylate and 50-5% by mole of a structural unit derived from vinyl cyclohexane when the total of the structural units derived from polymerizable monomers is taken as 100% by mole. Another embodiment of the present invention is a multilayer hard coating film which comprises a second hard coating in addition to a first hard coating, and wherein: the first hard coating contains (C) a silane coupling agent in addition to the above-described components (A) and (B); and the second hard coating is formed from a coating material that contains a specific amount of (A) a polyfunctional (meth)acrylate and a specific amount of (D) inorganic fine particles having an average particle diameter of 1-300 nm.
