Document Type and Number:
WIPO Patent Application WO/2019/146622
Kind Code:
A1
Abstract:
The present invention provides a hard coating film which exhibits excellent adhesion (especially, long-term adhesion) between a hard coating layer and a base material in cases where a cycloolefin polymer film is used as the base material. This hard coating film is obtained by superposing a hard coating layer, which contains an ionizing radiation curable resin, on at least one surface of a cycloolefin polymer base film, with a primer layer being interposed therebetween. The primer layer has an arithmetic mean surface roughness (Ra) within the range of from 0.5 nm to 15.0 nm; and the surface of the primer layer has a coefficient of static friction within the range of from 0.6 to 2.0.
