Abstract: An embodiment provides an adhesive film having, in order from the surface layer side, a first hard coat, a second hard coat, a transparent resin film layer, and an adhesive layer. The first hard coat is formed from a coating that does not include inorganic particles. The second hard coat is formed from a coating that includes inorganic particles. The adhesive film satisfies the following conditions: (i) the total light transmittance is at least 85%; and (vii) the pencil hardness of the first hard coat surface is at least 5H. Another embodiment provides an adhesive film having, in order from the surface layer side, a first hard coat, a second hard coat, a transparent resin film layer, and an adhesive layer. The first hard coat is formed from a coating that does not include inorganic particles. The second hard coat is formed from a coating that includes inorganic particles. The adhesive film satisfies the following conditions: (i) the total light transmittance is at least 85%; (iv) the water contact angle at the first hard coat surface is at least 100 degrees; and (v) the water contact angle at the first hard coat surface after 20,000 reciprocal cotton rubs is at least 100 degrees.

Abstract: Embodiments provide a pressure-sensitive adhesive film having (α) a poly(meth)acrylimide-based resin film layer and (γ) a pressure-sensitive adhesive agent layer in that order from the surface layer side and having a total light transmittance of 80% or higher. The pressure-sensitive adhesive film may further have (δ) a hard coat layer on the surface layer side of the poly(meth)acrylimide-based resin film layer (α). This hard coat layer (δ) may comprise an active energy ray-curable resin composition that contains (A) 100 parts by mass of a polyfunctional (meth)acrylate; (B) 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; (C) 0.05-3 parts by mass of organic titanium; and (D) 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm. This active energy ray-curable resin composition may further contain (E) 0.01-7 parts by mass of a water-repelling agent.
