Abstract: A Cd-free blue fluorescent quantum dot with a narrow fluorescence FWHM. The quantum dot does not contain cadmium and its fluorescence FWHM is 25 nm or less. The quantum dot is preferably a nanocrystal containing zinc and selenium or zinc and selenium and sulfur. Further, the quantum dot preferably has a core-shell structure in which the nanocrystal serves as a core and the surface of the core is coated with a shell.

Abstract: The present invention provides a curable composition which has a viscosity suitable for spray coating even at a high solid content and from which a cured product, on which precipitation of an ultraviolet absorber is suppressed and which has excellent weatherability and hot water resistance, is obtained, a cured product using the curable composition, and a stacked body. Provided is a curable composition including: a (meth)acrylate A; a urethane (meth)acrylate B; an ultraviolet absorber C; and a photopolymerization initiator D, in which the (meth)acrylate A has at least one of a dendrimer structure and a hyperbranched structure, a content of the (meth)acrylate A is 55 parts by mass to 95 parts by mass based on 100 parts by mass in total of the (meth)acrylate A and the urethane (meth)acrylate B, a content of the ultraviolet absorber C is 1.
