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.
