AF Grade<Focusing on Fingerprint Resistance>
The Shoshimon Film “AF Grade” is a new type of fingerprint-resistant hard coat film that prevents fingerprint stains. Fingerprints do not stand out and are easy to wipe off, making this hard coat film suitable to use on the surface of mobile devices such as smartphones and digital cameras.

Fingerprint Resistance Measurement
Fingerprint Resistance Measurement Method:
After adding a fingerprint to the Shoshimon hard coat surface, the variation of Haze from before and after the fingerprint was added is measured. The finger print area is also wiped back and forth 5 and 10 times with a bemcot(250g/cm2 load), and the variation of Haze is measured during that.
