Patent ID: 8309202

Claim:
A hard-coated film, comprising: a polyester film; and a hard coat layer placed on at least one side of the polyester film, wherein the hard coat layer comprises a multi-functional acrylate, another monofunctional or bifunctional acrylate, and a melamine-based crosslinking agent, the hard-coated film has a heat shrinkage ratio of at most 0.8% at 150° C. for 30 minutes in at least one direction, the hard coat layer has a surface with irregularities, an interface between the polyester film and the hard coat layer has irregularities on the polyester film side, such that projections of the irregularities on the polyester film side coincide with projections of the hard coat surface profile in the thickness direction, and the surface of the hard coat layer has 3D surface roughness parameters comprising an arithmetical mean deviation of surface Sa of from 15 nm to less than 150 nm and a kurtosis of surface height distribution Sku of from 1.5 to 5.
