<P>PROBLEM TO BE SOLVED: To provide a hard coat film which makes it possible to prevent blocking. <P>SOLUTION: The hard coat film is a film with a hard coat layer formed on a base material which satisfies the conditions required by following formulas (I) to (III). (I) is shown as 0.025μm≤Ra≤0.15μm. (II) is shown as 0.06μm≤Rz≤0.6μm. (III) is shown as 14μm≤RSm≤120μm. In formula (I) Ra is a centerline average roughness, in formula (II) Rz is a 10-point average roughness, and in formula (III) RSm is an average length of contour curve factor. The hard coating film has a fine unevenness on the surface of the hard coating layer in order to meet the conditions required by formulas (I) to (III), as a result of which blocking can be prevented. <P>COPYRIGHT: (C)2004,JPO |
