Title:
HARD COAT FILM, AND HARD COAT FILM HAVING SCRATCH-RESISTANT LAYER ATTACHED THERETO
Document Type and Number:
WIPO Patent Application WO/2019/171989
Kind Code:
A1
Abstract:
The present invention provides: a hard coat film provided with a hard coat layer formed on at least one surface of a substrate, wherein the hard coat layer contains a matrix component and inorganic microparticles having an average primary particle diameter of 3 to 100 nm, the content of the inorganic microparticles in the hard coat layer is 50 to 90 vol% inclusive, and specific relation formulae are satisfied in such an indentation test that a load is applied in the vertical direction against a surface of the hard coat layer which is opposed to the substrate side of the hard coat layer using a diamond-made knoop indenter, wherein E10 represents the indentation elastic modulus obtained when the indenter is indented by 10% relative to the thickness of the hard coat layer and E2 represents the indentation elastic modulus obtained when the indenter is indented by 2% relative to the thickness of the hard coat layer; and a hard coat film having a scratch-resistant layer attached thereto. (1) E10 − E2 ≥ 2 GPa; (2) E10 ≥ 8 GPa; and (3) E2 ≤ 8 GPa
