Title:
HARD COAT FILM
Document Type and Number:
WIPO Patent Application WO/2017/002779
Kind Code:
A1
Abstract:
The present invention provides a hard coat film that offers excellent anti-Newton ring effects and sustained visibility, reduces the haze value, suppresses contrast degradation and drops in transmittance, and can sustain the visibility of a display. This hard coat film 10 comprises a hard coat layer 2 on a transparent film base material 1, the hard coat layer 2 containing fine particles A and an ionizing radiation-curable resin. The fine particles A are organic particles. The difference in the refractive indices of the ionizing radiation-curable resin and the fine particles A in the hard coat layer 2 is greater than 0.001 and at most 0.050, and the film thickness T from the ionizing radiation-curable resin in the hard coat layer 2 is 0.7-2.0 times the average particle size of the fine particles A.
