Title:
ANTIREFLECTIVE PLATE
Document Type and Number:
WIPO Patent Application WO/2019/202942
Kind Code:
A1
Abstract:
An antireflective plate in which a hard coat layer, an antireflective layer having a low-refractive-index layer, a protective layer, and an overcoat layer are layered in this order on a transparent resin substrate, the antireflective plate being characterized in that the low-refractive-index layer is a cured body of a curable composition containing (B-2) 50-200 parts by mass of hollow silica fine particles having an average particle diameter of 10-150 nm with respect to a total of 100 parts by mass of (C) 90-98 parts by mass of a silane coupling compound or a hydrolysate thereof and (D) 10-2 parts by mass of a metal chelate compound, the refractive index of the low-refractive-index layer being 1.20-1.45, the protective layer is a cured body of a curable composition containing (B-3) 7.5-35 parts by mass of spherical silica fine particles having an average particle diameter of 10 nm or less with respect to a total of 100 parts by mass of (C) 90-98 parts by mass of a silane coupling compound or a hydrolysate thereof and (D) 10-2 parts by mass of a metal chelate compound, the protective layer having a thickness of 10-15 nm and a refractive index of 1.45-1.50, and the overcoat layer comprises (E) a polymer of a fluorine-containing silicon compound. The antireflective plate exhibits high antireflective ability as well as excellent wear resistance and antifouling properties.
