Title:
HARD COATING MATERIAL AND FILM OBTAINED WITH THE SAME
Document Type and Number:
WIPO Patent Application WO/2000/034396
Kind Code:
A1
Abstract:
A transparent hard coating material curable with heat or ultraviolet which is suitable for forming on a substrate, such as a film or sheet, an antireflection film functioning to reduce external light reflection and heighten the transmittance of light and having a low refractive index. The transparent hard coating material comprises an ultraviolet- or heat-curable resin having one or more (meth)acryloyl groups per molecule and colloidal particles of a silica/magnesium fluoride hydrate composite. It gives a transparent cured film having a refractive index of 1.48 or lower.
