- Comparative Example 3 and Comparative Example 4 both contained a leveling agent of a different type from the Examples, and the contact angle on the surface of the hard coat layer was that in Comparative Example 3 for both water and hexadecane. If the numerical value deviates and the contact angle of water deviates from the numerical value of the present invention in Comparative Example 4, the wettability of the surface of the hard coat layer is insufficient, which is unsuitable for use as a base material for adhesion.
