Kind Code:
A
Abstract:

To provide an antireflection article for sufficiently lowering the reflectance even when the refractive index of a transparent base material is high, to provide a molded article obtained from the antireflection article, and to provide automobile parts provided with the antireflection article and the molded article.

The antireflection article comprises: a transparent base material 3; at least one layer of intermediate layer 2 which is formed on at least one surface of the transparent base material 3 and has a refractive index different from the transparent base material; and a first layer 1 which is formed via the intermediate layer 2, made of a cured material of an active energy ray curable resin composition and has a fine rugged structure with a period of wavelength of visible light or less, wherein a difference of refractive index between respective adjacent layers is 0.01 to 0.11 and, when ns is refractive index of the transparent base material 3 and n1 is refractive index of the cured material of the active energy ray curable resin composition, ns and n1 satisfy the relation (1):0.03|ns-n1|0.17.
