Abstract
A material having a low refractive index that exhibits sufficiently low refractive index without deteriorating the strength of cured film produced therefrom, that can be cured by an active energy ray that is applicable for a resin base material that is not desired to be exposed to heat. Curable composition including: siloxane oligomer (a) containing a radically polymerizable double bond obtained through hydrolysis and condensation of alkoxysilanes containing at least an alkoxysilane A of Formula [1] and alkoxysilane B of Formula [2] in an amount of 100 parts by mass; inorganic fine particles (b) in amount of 10 parts by mass to 1,000 parts by mass; polymerization initiator (c) generating a radical upon active energy ray irradiation in an amount of 0.1 parts by mass to 25 parts by massRSi(OR)  [1]RSi(OR)  [2]a cured film produced from the composition, and a laminate including a low refractive index layer produced from the composition.
