Document Type and Number:
WIPO Patent Application WO/2019/087963
Kind Code:
A1
Abstract:
The present invention provides a hard coat film provided with an adhesive layer, having a pencil hardness of 3H or more, and capable of improving the visibility of a screen by suppressing the reflection of external light and of ensuring the visibility of the screen regardless of any angle when wearing polarized sunglasses. The hard coat film with the adhesive layer comprises: a base material made of a transmissive resin film with a retardation of 5,000 – 30,000 nm; a hard coat layer provided on one surface of the base material; an antireflection layer provided on the opposite side of the hard coat layer from the base material; and an adhesive layer provided on the opposite side of the base material from the hard coat layer. The hard coat layer has a thickness of 3 – 15 µm and is made of a curable resin. The antireflection layer has a thickness of 50 – 150 nm and a refractive index of 1.20 – 1.40. The adhesive layer has a thickness of 5 – 20 µm and a coefficient of dynamic friction of 0.05 – 0.30 on the outermost surface that is opposite the base material.
