1. An antireflective article comprising:
a chemically reinforced glass substrate with a surface compressive stress of 30 kg/mm2 or more; and an antireflection layer containing a binder resin, metal oxide particles, and a metal chelate catalyst, above the chemically reinforced glass substrate, wherein the antireflection layer has a moth-eye structure in an unevenness shape constituted by the metal oxide particles on a surface at a side opposite to a side at which the chemically reinforced glass substrate is provided, the unevenness shape of the antireflection layer has a ratio B/A of 0.5 or more, which is a ratio of a distance B between a center of apexes of adjacent convex portions and a concave portion to a distance A between the apexes of the adjacent convex portions, an average primary particle diameter of the metal oxide particles is 150 nm to 380 nm, a surface hydroxyl group content of the metal oxide particles is 1.00×10−1 or less, an indentation hardness of the metal oxide particles is 400 MPa or more, and the binder resin is a resin formed by a hydrolysis and a condensation reaction of a compound represented by Formula (1):
Rn—Si—X4-n Formula (1) wherein R represents an alkyl group having 1 to 10 carbon atoms, which may be substituted with other elements than a carbon atom, X represents a hydrolysable group, n represents 0 to 2, R's may be same or different, and X's may be same or different. |
