Document Type and Number:
WIPO Patent Application WO/2012/018087
Kind Code:
A1
Abstract:
Provided is a HC film having high hardness, satisfactory blocking resistance, low haze and high total light transmittance. A curable resin composition for a hardcoat layer, characterized by comprising (A) reactive silica microparticles each of which has a photocurable group on the surface thereof and which have an average primary particle diameter of 10-100 nm, (B) a smoothing agent which has an average primary particle diameter of 100-300 nm, (C) secondary particles each of which contains the smoothing agent (B) and which have an average secondary particle diameter of 500-2000 nm, (D) a polyfunctional monomer which has at least two reactive functional groups having crosslinking reactivity with the photocurable group in the reactive silica microparticles (A) per molecule and which has a molecular weight of 1000 or less, and (E) a solvent, and also characterized in that any secondary particle having an average secondary particle diameter of more than 2000 nm is not contained and the smoothing agent (B) is contained in an amount of 0.2-8 mass% relative to the total mass of the reactive silica microparticle (A) and the polyfunctional monomer (D).
